THJi;  VALUES  OF  TKE  GARDEN 


Mrs.  A.  G-.  C-uuTOner 
Past  President,  Florida  Federation  of  Crarden  Clubs 

I  am  most  confident  that  I  but  echo  the  sentiments  of  hundreds  of  those 
v;ho  ere  listening  in  '.vhen  I  exprees  appreciation  and  gratitude  to  the  Agri- 
cultural Experiment  Station  and  the  Agricultu.ral  CollGje  of  the  University  of 
Florida  for  the  opportujiity  again  ^.^ivon  ns   to  glean  information  through  this 
second  series  of  Radio  Garden  Talks. 

While  I  esteem  greatly  the  cosaplimsnt  paid  to  me  when  I  was  asked  to 
raalce  these  opening  remarks,  I  speaJc  as  a  ;,iere  enthusiast  —  one  who  is  happy- 
over  what  she  has  learned  and  most  hopeful  as  to  what  she  vvill  learn. 

Probably  no  word  of  six  letters  —  save  only  the  words  Mother  and  Fa- 
ther —  can  and  d03s  bring  so  much  ci  help  and  satisfaction  to  m-inkind  as 
does  the  word  gn^rden.  It  is  a  passport  into  foreign  lands  and  -/.lether  or  not 
we  speak  their  tongue,  ~3  know  that  the  French  word  "jardin,"  the  Spanish 
"jardin,"  the  German  "t'lrten,''  and  the  Italian  "giardino"  are,  after  all,  but 
our  "garden;"  and  understc-^ndiug  their  pec  iiar  langimge  each  flower  brings  to 
us  a  smile  of  joyful  recognition,  v/hsrever  ^'e  may  meet  it. 

Believing?-  that  possibly  the  surest  v/ay  to  prove  the  underlying  dominance 
of  the  garden  in  the  lives  of  t'lo  h/u^iian  race  today  would  be  to  give  a  con- 
densed history  of  Gardening  Art  from  its  very  beginning,  I  intend  to  follow 
that  course  of  thought. 

In  E,°ypt ,  the  very  cradle  of  all  h-::.iiian  civilization,  we  find,  resultant 
from  the  peculiar  clmracter  of  the  soil  .'-^.  u  clinate,  an  early  and  important 
development  of  garden  cultivation.  Indeed,  all  horticulture  arose  from  their 
profit-making  care  of  plants.  The  Egjqptian  demanded  and  obtained  from  his 
garden  edible  fruits,  medicinal  herbs,  timber  and  shade.  He  valued  first  his 
trees,  then  his  vinc:'ards,  vG2;ot?hles,  flowers,  whiles  -'ind  ■•"v-.ter,   nil  of  which 
he  enclosed  within  walls.  Thus  it  v.-as  he  who  definitelj''  established  a  ma- 
terial, commercial,  spiritu^d  and  esthetic  value  to  the  garden  and  from  those 
days  down  to  the  present  that  a.ppr,'is;'l  has  held.  This  information  comes  to 
us  authoritatively  through  the  paii.ti.'_';s  fo\"<.nd  upon  the  v^alls  of  the  tombs  of 
kings  and  men  of  wealth;  very  often  e\ ?.n  the  plans  of  their  gardens  were  de- 
picted there.  From  Egj'pt  we  learn,  too,  of  the  use  m^.iicind  made,  long  before 
the  days  of  Christ,  of  the  fig,  the  olive,  the  syca.rrx)re  tree  and  the  date 
palm.  'We  learn  of  the  papyrus  by  means  of  which  groat  funds  of  knowledge 
have  been  handed  down  to  us,  and  of  the  beautiful  lotus  flower  which,  com- 
bined with  the  leaf  of  the  acanthuij ,  has  served  as  one  of  the  most  di.gnified 
and  artistic  types  of  forr.al  decoration. 

The  Babylonians  and  Syrians  invented  the  hanging  gardens. 


-  ?  _ 


To  the  Medes  pjid  -er^iaus  we  particvlaxl;7  o^ive  our  appreciation  of  trees. 
As  a  me.tter  of  fact,  when  t!ie  G-reeks  in-.^deJ  those  covntr". es  they   found  mar- 
velous parks,  which  were  nientioned  repeatedly  in  their  literature.   Zencphen 
even  used  the  term  "Paradise"  to  describe  a  Persian  garden,  and  Lysander  was 
enthusiastic  not  so  :.v-"h  over  the  beauty  of  these  parks  as  over  the  clever- 
ness of  the  minds  that  designed  and  ordeied  them.  Groves  7/ere  often  planted 
around  tombs  —  we  Icnov/  that  years  later  the  body  of  Our  Savior  was  bui'iod  in 
the  private  garden  of  Arimathea, 

We  who  take  the  Garden  of  Eden  as  the  beginning  of  all  things  find  that 
it  is  described  as  exactlj'-  like  the  oriental  tree  parks  of  Persia, 

Jerusalem  had  its  great  gardens,  which  were  located  outside  the  city 
walls. 

Of  course,  all  gardeners  knoiY  that  religion  was  closely  connected  with 
gardening,  and  much  has  come  do'vn  to  us  from  that  son.rce.  This  is  especially 
true  as  regards  India,  where  they  worshipped  the  trees,  ''-•'^..i  Buddlia  had  a 
different  species  of  tree  as  his  sacred  symbol.  The  follovdng  description  of 
the  location  and  plan  of  a  3uddhist  park  would  seem  to  comply  absolutely  with 
the  requirements  of  our  parks  of  today:  "Hot  too  near  the  town,  and  not  too 
far  away,  well  provided  with  entrances,  easily  reached  bj;-  people  who  like  to 
come,  not  too  noisy  by  day.  perfectly  qi  let  by  ni.ght,  removed  from  disturbance 
and  crowds,  a  place  of  retreat  and  lonely  contemplation." 

But  we   must  hasten  on  in  this  brief  summary  of  the  garden's  development. 
The  Greeks  left  beautiful  villa  gardens  as  an  inlieritance  to  the  Romans;  the 
Bysantines  brought  oriental  influence  with  its  ornateness  into  general  use; 
the  Italians  iiitrodi\ced  the  baroque  style  and  definitely  relegated  fruit  trees 
and  vegetables  to  the  kitchen  gardens.  They,  like  their  immediate  predeces- 
sors, the  BjT-santines,  arrangtd  the  £.:ardtj-i  in  terraces  and  deipanded  fine  vis- 
tas and  views.  Eoof  gardens,  -vhich  we  look  upon  as  a  recent  experiment,  were 
thriving  on  the  town  roofs  in  the  outskirts  of  old  Rome.  Truly,  in  the  first 
centuries  of  Imperial  Rome  the  art  of  .2;ardening  had  reached  a  degree  of  per- 
fection t'nat  has  never  been  siirpassed.  Water  was  abundant  and  the  fountains 
and  cascades  found  in  the  gardens  of  Iteiy  formed  an  inspiration  for  the  land- 
scape architects  of  m^.ny  nations. 

Spain  tells  its  story  in  the  wondorful  gardens  of  the  Alhambra  and  the 
Generalife:  very  e:^tensive,  very  ornate,  very  full  of  s-'onshine,  and  rath  pot- 
ted plants  everywhere  in  evidence. 

Then  came  the  French  influence  in  the  time  of  the  Renaissance.  Perfe'.:- 
tion  of  formal  planting  developed,  ieautiful  iomitaius  abourided.  Franct,  fwl 
lowed  the  gardening  ideas  of  the  Italipn  artisans  bej^ond  the  Alps  and  final? y 
cominanded  the  lead.   Germany  and  Russia  vied  with  each  other  in  aspiring  tc 
sr.rpass  the  efforts  of  the  French,  but  neither  of  them  ever  succeeded,  for 
certainly  not  the  attempt  of  Frederic  the  Great  in  the  Gardens  of  Sans  Souci, 
nor  that  of  Peter  the  Great  at  Peterhof,  can  compete  with  the  perfection 
wrouglat  by  Louis  XIV  at  Versailles.

England  it  was  in  reality  wliich  gave  to  us  the  t^rpe  of  gai-den  that  we  so 
admire  today.  The  broad  expanse  of  lavns,  the  massing  of  shrubbery  and  the 
rock  garden.  Yet,  though  we  liave  i'ollowed  her  exanrple  in  so  many  lines,  she 
still  delights  in  one  feature,  comparatively  unkno\7n  to  us  —  I  ^illude  to  the 
topiary  art. 

America,  it  would  seem,  lost  no  time  in  hui.ioring  her  innate  love  for  the 
garden,  since,  yoxuig  as  we  are,  we  may  boast  of  early  gardens  near  Salem, 
Massachusetts  and  Charleston,  South  Carolina,  dating  to  the  late  l600's. 

But  with  this  cursory  outline,  we  n-.ust  /or  leave  the  pa,st  and  think  of 
the  present  and  the  imi'aediate  future.  Let  us  speai;  of  our  own  state,  Florida, 
and  of  v-hat  value  a  garden  may  be  to  her.  Perhaps  intuitively  we  first  think 
of  the  esthetic  and  inspirational  value  of  a  garden.  We  should  not  do  so,  for, 
important  as  that  phase  is,  the  material  and  commercial  service  far  outbalance 
it.  Of  course,  the  nearer  we  can  live  to  Mother  Earth  the  better  for  us  phy- 
sically and  spiritually  —  we  all  know  that.  T7e  knov;,  too,  that  nothing  is 
of  i^ioch  more  benefit  to  a  city  than  well  kept  gardens  and  parks.  Their  influ- 
ence and  exa:rjpl3  are  farther  reaching  than  we  who  plan  thera  realise.  So,  if 
ill  health  or  other  de^^^rrent  circvanGtances  prevent  you  frou  participating  in 
various  and  sundry  civic  activities,  do  not  for  one  moment  feel  that  you  are 
not  aiding  your  community  to  a  mp.rked  degree  when  you  give  your  ovm  surround- 
ings proper  care  and  attention. 

And  now,  another  and  a  brc  vi?r  thought,  —  namely,  that  we  should  try 
nnich  more  pains talcingly  than  we  do  to  malce  use  of  gardens  in  connection  vrith 
each  and  every  hotel  in  our  state,  whether  it  ic.  located  in  the  heart  of  the 
city  or  in  the  suburbs.  There  is  no  section  too  crowded  or  too  costly  in  the 
Old  World  to  influence  the  hotel  ov;ner,  v/ho  caters  to  the  best  of  the  travel- 
ling public,  to  abandon  a  garden  in  connection  with  his  hotel.  If  one  ma,y 
dine  outside  in  the  capitals  of  Europe,  why  not  in  lovely  Florida? 

We  all  know  that  C.  W.  Barron,  the  dean  of  financial  editors,  struck  a 
true  key  when  he  affirmed  that  ours  was  a  "Luxury  State;"  everything  that  we 
■>•'■■  ve,  from  our  climate  and  beach^c!  to  our  choice  oranges,  celery  and  early 
f  ■;.■••■  berries,  are  luxuries.  We  who  live  in  the  irddst  of  these  choice  things 
h  •••.•. •).'■..  •■'••i.lize  their  values,  but  ^^(5  should.  Our  clii..c-';-i' ::.nu  soil  were  here 
when  ■:>)•.,•■■;  ■-.-!  Leon  arrived.  The  o.-dinary  ma.rkot  b;,;":.-.-/:  i3  supplied;  but  the 
eztraora '-.ary  basket  is  still  not  filled  to  overflowing.  The  time  once  v;as, 
before  methods  of  transportation  and  communication  -/ere  so  v/ell  perfected  as 
they  now  are,  t]ia,t  alTXist  each  and  ever3'  one  of  us  had  a  kitchen  garden.  We 
lived  much  less  expensively  then;  those  days  may  be  returring.  If  so,  we  re- 
sidents of  this  "Luxury  State"  <v^.y   deem  ourselves  doubly  fortunate.  We  should 
appreciate,  as  Mr.  Barron  says,  that  "the  way  for  Florida  and  particularly  for 
South  Florida,  is  to  coin  her  simshine  a,nd  ner  soil  into  food,  fruits  and 
flowers  for  the  great  markets  of  the  North,"  This  is,  of  course,  being  done 
increasingly  from  year  to  year.  But  we  mast  do  more  —  we  .rrust  educate  our 
customers  to  understand  the  enjoyment  and  the  value  of  such  things  as  the  pa- 
payas, the  improved  mangoes,  the  avocado  x^ears  and  our  choice  pineapples. 

Indeed,  we  must  carry  on  more  exhaustive  experiments  in  endeavoring  to 


-  u  - 


find  new  tropical  friiits  adfiptalDle  to  oiar  climatic  conditions  and  new  cross- 
es (such  as  oiir  yotmgberry) ,  realizing  that  ntuch  lies  before  us.   Though  the 
colossal  geniris  of  Thonifis  A.  Edison  may  no  longer  serve  us,  some  one  may  car- 
ry on  his  experiments,  and  r;e  shall  produce  rubber  right  here  in  Tlorida.  It 
does  not  seem  impossible  ',7hen  we  realise  that  such  common  plants  as  the  olean- 
der, goldenrod  and  flaine  vine  have  a  rubber  content. 

Do  you  know  that  one  narcissus  farm  in  our  state  produced  more  bulbs 
than  any  other  such  farm  in  the  United  States?  Could  we  perchance  comrriercial- 
ize  extensively  our  gerberas,  nerines,  watsonias  and  other  plants? 

Kuch  ti-uly  is  possible,  when  so  prorrdnent  a  botanist  as  the  late  Dr. 
L.  H.  Pammell,  of  lo'-a  State  College,  made  the  assertion  that  Florida  has 
the  most  wonderful  plant  life  of  any  state  in  the  country* 

And  yet,  however  mi.ch  I  am  persuaded  cf  the  healthful  and  commercial 
values  of  a  garden,  t?ie  fact  remains  in  m^r   .rdnd  that  beyond  the  shadow  of  a 
doubt  there  still  does  and  cilways  will  hover  about  our  personal  garden  spot 
an  inexpressible  delight  in  its  perfection,  an  indescribable  charm  in  its 
color  hariTiony,  an  luatold  joy  in  the  ability  to  share  its  beauty  v/ith  others, 
an  indisputable  privilege  of  weavin;-';  o\ir  o~i:   Tsrsonality  into  its  every  de- 
tail, a  never  ending  op;;':>ri;unity  of  -:erving  OiW   Tolant  children  with  a  kind- 
ness l:!.}':e  u".to  that  best.y/Gd  vvo-'   our  U'coian  children,  and  lastly  and  predomi- 
nantly a  wonderful  ins-oi ration  which  i":!  ?.-tin  to  the  Divine  when  we  have  need 
of  repose.  ''There,  indeed,  could  -'e  find  vcy :   yjn.r..-.   --ith  the  world,  more

We  all  know  that  if  a  plant  (or  an  animal,  too,  for  that  matter) 
is  burned,  there  remains  an  ash  T/hich  forms  a  very  insignificant  frac- 
tion of  the  original  weight  of  the  plant,  say  about  1^.  In  this  ash  is 
found,  by  chemical  analysis,  the  so-called  mineral  constituents  of  the 
plant.  In  the  gases  arising  from  the  burning  process  are  foimd  the  car- 
bon, hydrogen,  oxj'gen  and  nitrogen  of  which  the  organic  portion  of  the 
plant,  such  as  sugars/  proteins,  is  composed.  This  carbon,  hydrogen, 
oxygen  and  nitrogen,  together  with  the  elements  present  in  the  ash,  form 
the  building-stones  of  which  the  complex  compounds  of  the  plant  are  built. 

ITow,  it  is  clear  that  during  the  process  of  growth,  these  bxiilding 
stones  imist  be  supplied  to  the  plant.  The  carbon  is  procured  by  the 
plant  from  the  atmosphere  in  the  form  of  carbon  dioxide;  the  oxygen  is 
available  either  in  the  atmosphere  or  in  the  water  that  the  plant  takes 
in.  The  hydrogen  also  can  be  obtained  from  the  water.  Consequently, 
these  elements  are  usually  available  to  the  plant,  while  the  supplying 
of  nitrogen,  as  everyone  knows,  forms  one  of  our  fertilizer  problems. 
The  constituents  of  the  ash,  that  is,  the  minerals,  obviously  mast  come 
from  the  soil.  It  is  to  these  minerals  that  we  call  attention. 

Some  20  or  30  years  ago,  scientists  listed  as  mineral  constituents 
of  the  soil  necessary  for  plant  growth  the  follcving  chemical  elements: 
calcium,  magnesium,  potassiiiin,  phosphorous,  sulfur  and  iron.   It  is  true 
that  small  amounts  of  copper,  nickel  and  other  metals  had  been  reported 
as  being  normal  constituents  of  plant  ash,  but  no  physiological  signi- 
ficance was  attached  to  these.   In  fact,  copper,  manganese,  arsenic, 
boron,  zinc  and  some  others  were  considered  toxic. 

But  science  is  never  satisfied.  Methods  of  chemical  analysis  were 
continually  being  improved,  enabling  the  analist  to  detect  smaller  quan- 
tities of  the  mineral  elements  in  the  soil  and  in  the  plant  ash.  As  a 
result  of  this  improvement  in  technique,  it  soon  became  apparent  that  the 
previous  classification  into  essential  minerals  and  toxic  minerals  was 
inadequate. 

The  inadequacy  of  the  older  classification  hinged  on  two  points, 
(1)  whether  or  not  a  given  mineral  exerted  a  toxic  or  a  salutary  effect 
depended  in  many  cases  on  the  amounts  of  the  mineral  present,  so  that 
even  toxic  elements  might  be  beneficial  in  small  amounts,  and  (2)  the 
effect  of  a  given  mineral  was  not  the  same  for  all  plants  so  that  it  be- 
came questionable  whether  one  could  write  a  list  of  essential  elements 
for  all  plants. 


-  2  - 


Although  copper,  rranganese  and  zinc  were  previously  listed  as  toxic 
elements  and  '7ere  not  included  in  the  list  of  essential  minerals,  experi- 
mental work  at  the  Kentucky  Experiment  Station  about  1925  and.  I926  showed 
that  copper,  manganese  and  zinc  axe  essential  in  small  amoTints  to  the 
growth  of  many  farm  crops.  Moreover,  about  192?  work  at  the  Everglades 
Branch  of  the  Florida  Experiment  Station  demonstrated  the  need  of  copper 
in  small  quantities  for  the  growth  of  some  50  or  60  different  crops  on 
the  peat  soils  of  the  Everglades. 

That  the  effect  of  a  given  element  is  not  the  same  on  all  plants  is 
evident  from  work  at  the  Rothams ted  Experiment  Station,  in  England,  There 
it  was  shown  that  certain  of  the  legume  plants  as  broad  beans,  soy  beans, 
and  some  clovers  will  not  grow  to  maturity  in  the  absence  of  boron, 
whereas  some  other  plants  as  wheat,  barley  and  rye  grow  readily  to  full 
maturity  without  a  trace  of  boron. 

Because  of  this  inadequacy  of  the  older  concept,  it  became  neces- 
sary to  revise  our  notions  of  plant  nutrition.  In  the  preparation  of 
plant  diets,  we  mast  consider  not  only  the  traditional  nitrogen-phospho- 
rus-potash r  equirements,  but  also  a  balanced  ration  of  essential  miner- 
als. 

The  most  commonly  occurring  essential  minerals  are,  of  coiirse,  phos- 
phorous, potash,  calcium,  magnesium,  sulfvir  aJid  iron.  Available  phos- 
phorous stimulates  root  growth  and  consequently  assists  in  reader   develop- 
ment of  small  seedlings,  while  potash  is  essential  for  proper  stem  and 
leaf  growth.  Calcium  is  important  in  the  transportation  of  starch  with- 
in the  plant,  'vhile  magnesium  is  a  constituent  of  chlorophyll,  the  green 
pigment  necessary  for  the  m£i.nufacture  of  the  plant's  organic  foods.  Sul- 
fur is  a  constituent  of  plant  proteins  and  the  presence  of  iron  is  ne- 
cessary for  the  loriTiation  of  chlorophyll. 

The  less  commonly  occurring  minerals  suc'Ja  as  copper,  maaiganese, 
boron  and  zinc,  because  of  the  extremely  small  qiaantities  involved,  pre- 
sent problems  of  a  peculiar  nature.  In  the  first  place,  there  arises 
the  question:  for  what  are  we  going  to  use  the  plant?  From  some  plants, 
fruit  is  wanted,  as  in  citrus;  from  other  plants  we  hope  to  secure  seed, 
as  in  com;  iii  other  plants  foliage  is  sought,  as  in  some  ornamental 
plants.  It  is,  of  course,  desirable  to  prepare  for  a  particular  plant 
a  diet  which  will  attain  the  result  desired  from  that  plajit.  Thus,  a 
beautifully  foliated  orange  tree  would  be  ornamental,  but  if  the  fruit 
were  made  insipid  to  the  point  of  being  unsaleable,  the  tree  could  not 
pay  for  its  board.  Past  experience  with  the  use  of  minerals  shows  clear- 
ly that  great 'caution  mast  be  exorcised  in  the  feeding  of  minerals  to 
plants. 

And  yet  it  is  our  job  to  find  the  particular  mineral  diet  which 
will  correct  abnormalities  as  they  appear  in  our  plants.  The  accumulat- 
ed mass  of  experimental  data  on  the  role  of  minerals  in  plant  nutrition 
s\iggests  strongly  that  the  minerals  miglit  liave  specific  physiologic  funo- 
tions  in  the  plant.  Thus  in  central  New  York,  lettuce  which  should  jdeld 


-  3  - 


solid  "heads"  produced  long  leaves  laio"m  as  "rabbit  ears;"  the  addition    . n 
of  copper  in  minute  amounts  corrected  this  trouble.   In  Florida,  absence 
or  deficiency  of  copper  results  in  yellowing  of  foliage  (called  clilorosis) 
This  abnormality  may  be  corrected  by  the  addition  of  a  small  amount  of 
copper  to  the  soil.  As  suggested  by  Thatcher,  President  of  Llassachusetts 
State  College,  we  may  soon  recognize  in  plant  nutrition  certain  factors 
designated  by  "anti-chlorosis"  (or  an ti -yell owing)  factor, /the  "flower- 
ing factor." 

A  second  major  problem  in  the  study  of  mineral  nutrition  of  plants 
lies  in  the  possible  cusiulative  effect  of  minerals  added  to  the  soil. 
The  continued  application  from  year  to  year  of  such  minerals  as  copper, 
manganese  and  zinc  might  result  in  such  alteration  of  the  nature  of  the 
soil  as  finally  to  destroy  the  fertility  we  seek.  Or,  on  the  other 
hand,  by  repeating  small  doses  of  copper  or  zinc  on  perennial  plants, 
the  iTineral  may  accumulate  in  the  plant  to  its  detriment  unless  the 
plant  can  eliminate  the  mineral  "by   defoliation,  dropping  of  fruit,  or 
some  other  means. 

Attention  is  called  to  these  two  problems  simply  as  a  caution  a- 
gainst  a  too  ready  use  of  mineral  supplements  to  the  soil,  in  particular 
the  less  commonly  occurring  mnerals.  The  fact  that  addition  of  copper 
to  the  peat  soils  of  the  Everglades  produces  favorable  response  in  a 
large  number  of  crops  is  no  criterion  tliat  the  same  dosage  of  copper  on 
soils  of  different  nature  will  react  favora.bl;r  to  the  growth  of  plants 
in  general.  The  fundamental  data  pertaining  to  the  effect  of  the  mi- 
nerals on  the  physiologic  raechanism  of  the  plant  and  on  the  character 
of  the  soil  liave  not  as  yet  been  obtained. 

The  l''loric"~  ''- ;'ri r. ;il tural  Experiment  Station  is  nor;  devoting  con- 
siderable attention  to  this  problem  of  mineral  nutrition  of  plants.  The 
physiologic  effects  of  certain  minerals  on  both  horticultural  and  field 
crops,  the  effect  of  the  mineral  supplements  on  the  soil,  the  relation 
of  mineral  supplements  to  animal  husbandrj'  problems,  such  as  "salt-sick," 
and  the  development  of  a  field  practice  in  the  use  of  mineral  supple- 
ments are  some  of  the  problems  engaging  the  attention  of  various  depart- 
ments of  the  station.  Prom  this  coordinated  attack  on  the  problem  there 
most  certainly  will  emerge  a  better  understaiiding  of  our  Florida  soils 
and  a  practicable  teclinique  for  correcting  some  of  our  soil  deficiencies. 

Meanwhile,  ve   need  not  worr;^  unduly  about  any  possible  deficiency 
of  the  loss  common  minerals  in  our  ornamental  gardens.  The  amounts  of 
these  less  common  minerals  needed  are  so  small  tha,t  in  iiiany  cases  these 
am.ounts  are  sxipplied  automatically  in  the  muck,  claj''  or  fertilizer  tlaat 
ma,y  be  used. 

In  the  case  of  those  minerals  which  are  needed  in  appreciable  a- 
mounts,  such  as  calcium,  potash  and  phosphorus,  the  effect  on  the  plant 
is  largely  dependent  upon  the  soil  reaction. 


-  u  - 


To  briefly  ffannarize,  there  are  two  general  classes  of  minerals, 
those  that  are  commonly  knorni  and  r.re  needed  in  appreciable  amounts 
and  those  tlir.t  are  needed  in  minute  arounts.  These  less  common  ones, 
such  as  copper,  mangaiiese,  zinc  and  others,  are  quite  vital  to  plant 
grovrth.  They  are  frequently  supplied  automatically  in  the  soil,  mack, 
fertilizer,  etc.  Where  there  is  sa\   actual  deficiency  of  some  of  them, 
study  of  the  special  problem  is  necessary  since  these  minerals  react  so 
differently  on  different  soils  said  with  difx"erent  plants.

SOIL  EEA.CTI01T  IN  KEIATIOU  TO  GAEDEIIING 
Dr.  0.  C.  Brj'an,  Professor  of  Soils 
and  Agronon^r,  University  of  Florida 
College  of  Agriculture 

Soil  reaction  is  one  of  the  most  deep  seated  factors  affecting  the 
growth  of  plants  in  general,  and  especially  is  this  true  for  garden 
plants.  For  a  gardener  to  ignore  this  factor  may  mean  failure  before 
he  begins. 

The  term  reaction  simply  means  a  soil  condition  which  indicates 
th?.t  the  soil  is  acid,  neutral,  or  alkaline.   It  is  measured  in  terms 
of  pH  values  which  gives  the  amount  of  active  acid  or  alkali  present. 
A  neutral  soil  has  a  pH  value  of  7.0  while  an  acid  soil  has  a  pH  value 
of  less  than  7,0  and  an  alkaline  soil  has  a  value  of  more  than  7.0.  In- 
creasing the  pH  val-oe  above  7.0  means  a  direct  increase  in  alkalinity. 
But  the  reverse  is  true  with  acids.  A  decrease  in  pH  value  from  7  to  1 
means  an  increase  in  the  amount  of  active  acid  present.  Since  the  pH 
value  is  a  logarithmic  expression  of  the  concentration  of  active  acid, 
the  value  of  pHc  is  ten  times  as  acid  as  a  pH  of  6,0  and  pHij.  is  ten  times 
as  acid  as  pHr,  Other  things  being  eajial   the  greater  the  acidity  of  the 
soil  the  greater  the  loss  of  calcium,  and  other  bases  through  leaching 
processes. 

In  hi-'./ld  climates  the  soil  processes  tend  toward  an  acid  reaction, 
due  to  excessive  leaching  of  bases.  While  in  an  arid  or  semi-arid  cli- 
mate the  soil  processes  tend  toward  an  alkaline  reaction  because  of  no 
leaching  of  bases.   Intermediate  climatic  conditions  irake  for  a  neutral 
soil.  Of  course,  the  degree  of  weathering,  or  soil  processes,  and  the 
nature  of  the  material  from  which  the  soil  was  derived,  affect  the  ajiaount 
of  acid  or  alkali  present. 

The  reaction  of  the  soil  may  influence  the  plant  in  several  ways: 
(l)  by  direct  corrosive  effect  on  the  roots  hindering  normal  root  de- 
velopment, (2)  by  depleting  the  soil  of  lime  and  other  basic  nutrients, 
(3)  by  dissolving  poisonous  substances,  such  as  aluminum,  in  the  soil 
and  thus  poisoning  the  plants,  (U)  by  retarding  the  growth  and  develop- 
ment of  beneficial  soil  organisms,  and  (5)  by  precipitating  plant  nutri- 
ents like  iron  and  manganese.  Any  one  of  these  factors  may  seriously 
hinder  the  growth  of  plants,  and  thus  cause  a  poor  garden  or  even  a 
failure.  To  get  the  most  from  a  garden  one  should  adjust  the  reaction 
of  the  soil  to  suit  the  optimum  needs  of  the  plants. 

As  previously  indicated,  humid  soils  are  generally  acid.  That 
means  that  most  of  Florida  soils  are  acid  in  reaction.  This  is  a  very 
important  consideration  for  gardeners  in  Florida.  Fortunately,  however, 
most  cultivated  plants  including  our  highly  prized  garden  specimens,

prefer  an  acid  soil.  Moreover,  a  large  portion  of  the  nild  flowering 
plants  so  common  in  Florida  not  only  tolerate  but  prefer  acid  soils  for 
best  production. 

It  is  not  only  interesting  but  a  significant  character  of  such 
plants  as  azalea,  hydrangea,  straxirberry  and  lily,  to  gro^r  most  success- 
fully on  rather  acid  soils.  This  is  true  of  the  rose  —  the  princess 
of  garden  plants.  These  facts  are  well  known  by  the  successful  gar- 
dener. The  time  old  custom  of  adding  leaf  mold  ajid  pi  uty  of  moisture 
to  flowering  and  garden  plants  induces  an  acid  condition  in  the  soil 
—  oftentimes  a  necessary  factor  for  success. 

It  should  not  be  inferred,  however,  that  all  garden  plants  pre- 
fer a  distinctly  acid  soil.  Just  the  reverse  is  true  with  some  plants. 
Such  plants  as  abelia,  celery,  geranium,  poppies  and  others  grow  best 
in  a  neutral  to  slightly  alkaline  soil.  These  differences  in  responses 
are  inherent  characteristics  of  the  plants  and  can  rarely  be  changed 
by  man.  Without  taking  these  plant  characteristics  into  consideration 
the  best  of  gardeners  can  not  make  a  success.  Oftentimes  the  most  se- 
rious problem  confronting  the  gardener  is  Ms  persistence  in  trying  to 
grow  plants  on  soils  with  unfavorable  reaction,  and  at  the  same  time 
having  s\utable  corrective  materials  that  he  could  use. 

The  cost  of  controlling  soil  reaction  is  relatively  small.   In 
fact,  too  small  to  interfere  "fith  the  success  of  the  gardener.  After 
all,  the  primarj'-  objective  of  the  gardener  is  to  so  adjust  all  his  soil 
conditions  that  healthy  and  beautiful  plants  may  be  grown.  To  do  this, 
it  is  essential  that  the  plant  be  adapted  to  the  reaction  of  his  soil, 
or  otherwise  he  must  adjust  the  soil  reaction  to  suit  the  needs  of  the 
plant.  This  is  of  first  degree  importaiice,  particularly  for  garden 
plants. 

By  the  use  of  physiologically  acid  fertilizers  such  as  sulfate 
of  amm.onia,  urea,  ar-'imonium.  phosphate,  and  leaf  m.old  the  grov/er  can  keep 
the  soil  sufficiently  ecid  for  the  acid-loving  plants,  —  azaleas, 
strawberries,  and  others.  Sometimes  it  may  be  necessary  to  use  even 
s'olfur  or  alurdnum  s'olfate  to  secure  the  desired  peaction.  AluninTOn 
siiLphate  will  increase  tho  acidity  of  the  soil  immediatoly  following 
application,  but  sulfur  requiros  several  weeks  before  it  brings  about 
a  more  acid  condition.   The  aluminum  sulfate  should  be  applied  at  tho 
rate  of  l/k   to  1  pound  per  square  yard  (depending  on  the  soil)  and  v;a- 
tered  in.  The  sulfur  should  be  mixed  vrith  the  soil  at  rate  of  2  to  ^ 
ounces  per  square  yard  and  the  soil  moistened.  It  is  very  essential 
to  avoid  the  use  of  hardwood  ashes,  lime  and  alkaline  materials  in 
growing  acid-loving  plants.  'Thile  on  the  other  hand,  to  grow  cabbage, 
celery,  dahlia  and  other  lime-loving  plants  successfully  it  becomes  ne- 
cessary to  avoid  the  use  of  much  phj'-siologically  acid  fertilizers.  Wi^-h 
such  plants  line,  hardwood  ashes  and  alkaline  forming  fertilizers  are 
essential,  and  necessary  for  success  on  most  Florida  soils.  With  sand^^ 
soils  low  in  organic  matter  1/^  to  1/2  pound  of  ground  lime  per  square 
yard  will  be  sufficient.  For  soils  having  ab^'ondant  organic  matter 
these  amounts  may  be  doubled.  Although  hardwood  ashes  are  not  as  con- 
centrated as  ground  lime,  they  are  more  active  in  bringing  about  a 
change  in  the  reaction  of  the  soil. 


-  3  - 


Altliou^h  a  n-joriber  of  garden  plants  grow  "best  on  distinctly  acid 
soils,  this  does  not  mean  that  such  plants  groTv  'Yithout  calciiun  and 
other  tasic  nutrients.  In  fact,  many  such  acid-loving  plants  require 
a  high  content  of  calcium  for  normal  development.  This  moans  that  for 
such  plants  the  grower  -^ill  need  to  add  calcium  in  some  neutral  or  acid 
form.  One  of  the  most  practical  ways  of  adding  calcium  under  such  con- 
dition is  in  the  foru  of  Superphosphate  at  the  rate  of  1/2  pound  per 
square  yard,  worked  into  the  soil.  With  many  plants  bone  meal  is  a 
very  desirable  calcium  carrier.  Bone  meal  is  not  only  safe  to  use  but 
it  improves  the  quality  of  the  soil,  thus  making  a  more  desirable  plant. 

It  should  be  emphasized  that  only  quality  plants  make  a  desirable 
garden.  This  means  that  a  successful  gardener  ;7ill  need  to  carefully 
consider  those  fundamental  factors  that  influence  the  internal  make-up 
of  the  plant.  To  influence  the  plant  for  quality,  the  grower  will  not 
only  see  that  plenty  of  available  plant  food  and  moisture  are  present, 
but  that  the  reaction  of  his  soil  is  properly  adjusted  for  the  plants 
concerned. 

It  is  just  as  essential  that  these  adjustments  be  made  for  garden 
plants,  as  proper  food  and  envirorjnent  e^re  essential  to  animals.  The 
Roman  gardener  referred  to  vjaking  a  soil  "fat"  for  plants  to  feed  upon. 

In  discussing  the  relation  of  soil  reaction  to  gardening,  the  ques- 
tion of  soil  texture  should  not  be  overlooked,  ^liile  it  is  true  that 
sandy  soils  respond  quickly  to  treatment,  they  may  rapidly  change  in  re- 
action following  an  application  of  certain  fertilizers,  and  oftentimes 
produce  injury  to  the  plants.  This  means  that  where  a  grower  desires  to 
correct  the  re:  ccidn  of  his  soil  with  soluble  fertilizer  materials  he 
will  need  to  be  more  caref-ol  about  the  amounts  to  apply  on  sands  than  on 
loams  or  clay  soils.  Soluble  fertilizers,  such  as  sulfate  of  ammonia, 
will  burn  tender  plants  if  placed  in  contact  -vith  the  roots  or  leaves. 
Therefore,  the  gardener  should  be  careful  about  the  method  and  rate  of 
application  of  such  fertilizers.  They  should  be  applied  broadcast  around 
the  plants  at  the  rate  of  1  to  2  ounces  per  square  yard.  Hardwood  ashes 
or  lime  applied  to  sandy  soils  often  will  cause  chlorosis.  To  correct 
this,alujiiintiin  sulfate  is  a  practical  material  to  use. 

One  of  the  best  ways  of  avoiding  rapid  changes  in  soil  reaction  from 
fertilizer  treatment,  is  to  add  abundant  amo-'onts  of  orga.nic  matter  such 
as  coRTpost,  leaf  mold,  or  some  other  available  form  of  organic  matter. 
For  small  areas,  the  gardener  may  deem  it  desirable  to  add  some  clay 
material  to  the  sands  for  the  purpose  of  adding  a  more  stable  body  to 
the  soil.  Where  plenty  of  organic  matter  and  clay  is  present,  the  reac- 
tion of  the  soil  will  be  m.ore  constant  and  thus  iiiake  it  possible  to  grow 
a  healthy  plant  and  consequently  a  better  plant. 

The  gardener  who  has  a  variety  of  plants  and  soils  can  well  afford 
to  study  his  soil  reaction  problem  for  individual  plants.   In  many  in- 
stances it  will  be  good  business  to  secure  a  small  soil  test  kit  for 
measuring  the  reaction  of  his  field  and  garden  soils.  These  kits  are 
simple  and  can  be  secured  at  a  small  cost.  Some  of  the  companies  hpjid- 
ling  them  will  supply  the  gardener  with  a  list  of  plants  together  with 


k  - 


their  optimum  soil  reaction.  This,  as  a  rule,  is  very  val viable  to  the 
amateur  gardener.  Although  the  average  laj-man  might  not  successf-ully 
use  the  soil  tester,  the  careful  gardener  can  secure  satisfactory  re- 
sults with  a  littlepractice.  Unless  the  gardener  does  give  his  soil 
reaction  prohlem  careful  attention,  his  chances  for  success  will  he 
small,  especially  for  certain  plants.  Proper  attention  and  care  at 
the  riglit  time  and  in  the  right  place  will  raal:e  a  successful  garden 
where  others  fail.

The  fo'.uia-  tion  of  successf-jl  gardening  rests  on  the  establishment 
and  maintenance  of  a  fertile  soil.  In  the  buildin»3  and  tending  of  a 
fertile  aoil,  the  skillful  gardener  is  reallv  gardening  underground, 
Ee  is  evil tiv;.. ting  and  nurturing  an  extensive  garden  of  minute  plants. 
If  properly  pampered  this  garden  of  grotesquely  shaped,  chaotically  ar- 
ranged, evn-  changing  .-nicroplants  y'III  go  a  long  yray   towards  insuring  a 
vigorous  a;id  healthy  garden  of  higher  plants.  These  microscopic  plants 
are  the  beneficial  soil  :nicroflora.  The  fertility  of  the  soil  depends 
on  the  gro^vth  and   the  activity  of  these  rnicroorganisms  to  a  large  ex- 
tent. They  are  the  life  of  the  soil. 

The  numbers  and  3:inds  of  t];e  beneficial  aoil  micro-organisms  vary 
under  different  co-iditions.  In  geii'^ral  the  more  fertile  a  soil  becomes, 
the  ;5rp.atGr  tha  nu.Aer  of  beneficial  mi  or  0  organisms  it  contains.  An 
adequEitely  cultivr-.ted,  uell-drained  soil,  i^hich  has  been  ab'Jind&ntly  sup- 
plied with  decomposing  organic  matter  and  liberally  trea'.ud  with  the  es- 
sential fijrtilizer  constituents  and  aniraal  nvinures,  utsiv'^.lly  contains  an 
ample  number  of  beneficial  i.iicroorgi?uiismG.  Soil  ariidity  and  unfavorable 
raoisture  conditions  are  detrinients  to  the  beneficial  soil  microflora. 
The  ntuabers  and  kinds  of  these  beneficial  rnicroplants  are  as  v;?  ied  and 
interesting  as  those  of  the  higher  plants.  They  have  beo''  .mbj  xtcd  to 
study  and  clascification  as  havo  the  higher  pl?jtite.

THE  ryUTZ-O?.   OF  EiP7IH02-:/EilT  ON  FLORIDA  GARDEN  PLAl^'TS 

P/  -  lil.D.   Co'ly,   Professor  of  Botany  and  Bacteriology, 
University  of  Florida. 


Along  v..-:lth  the  nineralc  and  the  role  thir.-  ;;lay  in  plant  production,  as  well 
as  on  the  types  of  soils  and  ho"v  they  i7iay  co  prepared  and  fertilized  to  best 
advantage  in  our  gardens ,  we  ;:.uc;t  co^iSlder  the  influence  of  environment  on 
garden  plants. 

'The  factors  that  comprise  ar.  enviroranent  are  vvater,  teiiiperature,  air,  light, 
soil,  plant  food,  animalo  and  other  plants.  Any  change  in  the  normal  position 
of  a  plant  requires  time  for  I'tadjustment  to  its  new  environment.  Failure  to 
make  this  proper  readjustment  results  in  ov"-normal  growth  or  death  of  tnn  plant. 

The  importance  of  "^at'^r  has  already  "been  "orout^^ht  out  in  considering  its  role 
in  n.ineral  transportation  in  the  soil,  as  viell  as  other  fuiictions  pf  rf orraed  by  it. 
It  is  very  vital  to  the  plant  in  keeping  the  tender  parts  from  collapsing,  to 
supply  the  needed  minerals  and  to  provide  a  proper  mediur.  for  fia-'.-hing  the  cells 
of  impurities.  For  example,  an  ai^.n-iua  to  thrive  must  have  an  abvjidance  of  water, 
yet  good  drainage  is  equally  essential. 

The  response  of  plants  tr.  ater  is  siach  as  to  group  thj-m  under  three  distinct 
divisions:   (l)  those  which  demand  an  abundance  of  water,  s"i.ch  as  submerged 
aquatics  and  swamp  plants;  (2)  those  that  require  a  irciueratd  thougii  constant 
supply  of  water,  such  as  most  of  :ar  annual  z^-"^'<-''^   ^^ic'  a^'-icultural  plants,  anc. 
(3)  those  which  do  best  on  very  l.^t'^le  i"j,fcei".  such  as  occ\  r  on  a  very  dry  soil, 
as  cacti,  liatris,  sunflowers  and  g?'''llar^.ia.  The   water  requirements  of  a  plant 
should  be  studied  and  then  carefully  applied  for  best  development. 

Plants  often  suffer  in  th(5  garden  fio.!  too  much  water  rather  than  from  too 
little.  A  water-soaked  coil, Is  lo-,v  in  oxygen,  and  it  ttnids  to  become  sour  from 
decomposition  that  goef:  on.  The- fir?  u  condition  can  be  corrected  through 
drainage,  and  the  second  by  a  judicious  use  of  lime.  A  wet  soil  is  also  cooler, 
which  retards  germination  and  grovjt';..  Too  frequent  watering  tends  to  shallow 
rooting,  c'..ud  when  watering  is  deLzyed   or  stopped  the  roots  may  be  unable  to  go 
down  deeper  into  the  soil,  and  insufficient  moisture  rises  to  meet  the  increased 
demands;  conseq-j.ently,  the  pl.-j-ts  wilt  and  soon  die.  The  rose  is  a  good  example. 
The  soil  becomes  packed  fror.  frequent  watering  and  is  lov7  in  oxygen  content. 
Other  dangers  from  too  wet  a  soil  are  scalding  of  the  lower  stems  and  mildewing 
of  the  leaves.  Danping  of.'!,  one  of  the  most  destructive  pests  of  seedlings, 
is  encouraged  by  •;et  soil  s  :.d  poor  aeriation.

Prequently  one  has  noticed  ho'v  plants  dronp  f>nd  their  leaves  wilt  or  curl 
when  exposed  to  dry  winds  or  severe  h3at ,  but  hc"  they  recover  gradually  when 
these  conditions  subside.  This  wilting  is  a  means  of  checking  the  evaporation 
of  water  (transpiration)  frorA  within  the  plant.  Toward  dusk  the  plant  recovers 
its  forcer  rigidity  "because  less  water  is  lost  than  is  absorbed.  Calr-dium, 
hydrangea  and  many  other  broad,  thin-leafed  plants  illustrate  this  condition. 

We  are  quite  familiar  with  the  value  of  starting  bulbs  in  thf  dark  for 
proper  root  development  and  while  the  leaves  are  almost  colorless  this  is 
corrected  shortly  after  bringing  them  into  the  light.  Yet  '.hen  th'^  j-;.l:s  are 
allov-ed  to  start  in  the  light  thu  roots  s.-'    poorly  forrrsd  and  the  leaves  are 
short  and  slender.  The  flower  star:r  ?.re  also  "hurt. 

Nast'artiim,  sunflo"er,  gaillrrdia,  --.elia  mid  many  other  plants  fare  best 
in  f-oll  sunii^lit  for  at  lea~t  the  groriter  part  of  the  day  than  in  the  shade. 
Arbor-vitae,  junipers,  roses,  sage  paLr:  and  :;.a:i7  of  our  conifers  require  much 
light  for  their  best  development;  hov;ever,  Liany  of  them  will  gro\7  in  moderate 
shade. 

Often  we  become  discouraged  with  o"a.r  la',7ns  because  the  grass  does  not 
spread  well  ■'binder  tho  trees  and  shr^abbery.  The  lack  of  S'ufficient  light  may  be 
the  cause  of  such  failure.  3err;rada  grass  requires  co-'.3idsrable  light  for  bc-iSt 
development.   St.  Ai-^g'ustine  grass  car.  adjust  itself  to  moderate  light.  Other 
factors,  such  as  lack  of  s';iiiicicnt  moisture  for  thu  grass  roots,  since  the 
other  vegetation  absorbs  it  faster,  or  the  toxic  effect  produced  by  root 
excretions  of  other  plants  nay  also  co-itribv;.te  to  the  lail-ure  of  the  grass  in 
such  areas. 

We  have  observed  how  certain  plants  struggle  for  light.  Plants  kept 
before  a  window  and  allowed  to  receive  li^^it  only  from  one  direction  will  lean  in 
this  direction, and  unless  their  position  is  changed  will  become  "one-sided". 
Plants  in  a  crowded  seed-bed,  or  Eaplin;;s  crowded  in  a  gro.-t,,  are  spindlirig 
largely  because  of  their  straggle  for  light.  Grap  • ,  Vi-rgir.ia  creeper,  clematis, 
okunbergia  and  a  number  of  vii.„L-  climb  over  .-n;  so^-t  of  a  support  for  light,  a..d 
in  some  instances  will  shut  off  practically  .ill  lifht  from  the  plants  upon  v/hich 
they  are  clinging.  A  very  good  cxcj^.nle  of  this  is  the  effect  the  Florida  or 
^panigh  Moss  has  upon  o-cjt   trees.  Ti.l.:-  plar.t  is  not  a  parasite,  as  some  believe, 
but  the  air,  light  and  moisture  it  cuts  off  reduces  the  vigor  of  the  tree. 

Light  is  very  vital' to  all  green  plants  because  it  enables  the  chlorophj'-ll, 
or  green  coloring  matter,  to  naice  plant  food.  Yet  sometimes  the 'light  is  too 
strong  so  the  plants  have  to  change  the  position  of  their  leaves,  or  modify 
their  leaf -form  to  correct  the  light.  YoiUig,  tender  leaves  and  stems  are 
frequently  of  a  reddish  tint.  Tl:is  pig-ment  tends  to  shield  the  chlorophyll  from 
the  destructive  effect  of  the  li;iilit.  Often  hairs  occur  upon  the  surfaces  of 
leaves  and  stems,  to  reduce  t.o-':.   only  light  but  also  transpiration.  These  hairs 
reflect  much  light,  thereby  reducing  the  direct  influence  of  the  rays.

A  plant  thriving  in  a  rr-r;;.  place  and  moved  to  a  cool  one  becomes  inactive 
until  it  has  adjusted  itself  to  its  nev:  home.  Possibly  it  can  never  do  this. 
The  reverse  is  true.  Some  plants  are  so  fixed  in  their  habits  that  much  time  is 
required  to  overcome  them.  This  is  v;3ll  bro'oght  out  by  the  deciduous  habit  of 
many  of  our  northern  plants  on  being  brouglit  southrv-ard.  Every  year' the  shedding 
of  tHe  leaves  occurs  at  about  the  same.  ti;;e  as  in  the  original  home,  yet.  after 
a  time,  shedding  of  foli?ige  starts  a  little  letter  in  accordance  r.'ith  the  period 
in  v/hich  the  plant  is  in.  Southern  plants  carried  north'vard  are  readily  caught 
by  early  frosts  and  are  frequently  unprepared  for  the  northern  -.Tinters  because  of 
the  slov/ness  in  ripenin.~  of  their  uood..  Frequently,  \7e  in  Gainesville  have  light 
touches  of  rinter  before  Christmas  which  tempers  off  the  r;ood  and  permits  the

tolerance  to  lo-.  temperature  i.-  tied  \.^   largely  •.rith  certain  chemical  changes 
occuring  in  the  wood  of  the  pla...t,  rhich  are  induced  by  the  first  touch  of  cold 
that  causes  the  sap  to  fall.  Dry  Soeds  can  r;ithsta;id  a  temperature  of  100  degrees 
Centigrade  or  a  little  above  for  varyin,-;  periods  but  water-soai-jcd  seed  are  readily 
killed  at  70  degrees  Centigrade,  so  plants  rich  in  sap  are  more  susceptible  to 
injury  from  temperature  extremes  than  those  low  in  sap. 

Many  plants  are  limited  solely  'oy   temper.at"xr...  l>-ny   costly  attempts  have 
been  made  to  grow  quinces,  cherries,  as  well  as  certain  desired  varieties  of 
peaches  in  certain  regions  of   the  South,  but  too  prolonged  high  tem.peratures  of 
cvjamer,  and  insufficient  cold  in  winter  to  stimvlate  the  plants  for  proper  grov7th

PREPARIIIG  AED  FERTILIZING  GARDEJT  SOUS 

By-  W.  A.  Leukel,  agronomist, 
Florida  Experiment  Station 

The  fertilisation  of  an  ornamental  garden  is  a  matter  "7here  considerable 
judgment  must  be  used  ''oy   the  individual.   Only  a  few  fundamental  facts  concern- 
ing the  chief  essentials  of  garden  fertilization  can  be  given  in  the  time  al- 
lotted here. 

Tlie  establishment  of  a  proper  soil  environment  for  plant  growth  is  one  of 
the  first  essentials  in  ornamental  gs.rdening.   Such  a  plant  environment  means 
a  friable  soil  high  in  organic  matter.   This  soil  condition  not  only  provides 
various  plant  nutrients  but  conserves  soil  moisture  so  essential  for  plant 
growth.   Organic  matter  when  needed  can  be  supplied  to  garden  soils  from  four 
sources  —  namely:  woods-mold,  barnyard  iTianure,  muck  or  well  rotted  compost. 
Barnyard  manure,  when  used,  should  be  well  rotted.   A  sufficient  amount  should 
be  used  to  prevent  leaching  in  sandy  soils  and  also  to  bring  about  a  more  fri- 
able condition  in  heavier  soils.  Manure  should  be  plowed  under  and  well  incor- 
porated with  the  soil  before  the  soil  is  used  for  the  growth  of  garden  plants^ 
If  added  while  moist,  its  value  will  be  enhanced.  Where  manure  is  not  avail- 
able, a  good  muck  may  be  incorporated  with  the  soil  to  equal  advantage.  Mucks 
should  likewise  be  incorporated  with  the  soil  sometime  before  garden  crops  are 
planted.  Most  mucks  are  low  in  bacterial  flora  and  therefore  vrhen  well  incor- 
porated with  the  soil  a  better  bacterial  activity  is  created  in  the  soil-muck 
mixture. 

Well  rotted  compost  can  be  applied  and  used  to  increase  soil  organic  mat- 
ter in  the  same  manner  as  in  the  case  of  muc-;s  and  barnyard  manure.   This  ma- 
terial can  be  prepared  by  composting  all  waste  vegetation  during  the  growing 
season./  Compost  should  always  be  prepared  in  connection  with  garden  fertili- 
zation/ 

TIThere  soils  have  a  high  clay  content,  packing  or  puddling  often  occurs 
after  heavy  rains.   Such  soils  are  hard  to  cultivate  when  in  this  condition. 
Where  the  garden  area  is  not  too  large,  saiid  may  be  incorporated  with  the  soil 
to  give  them  a  loamy  consistency  and  make  them  easier  to  cultivate.  Where  the 
garden  area  is  of  considerable  size,  lime  ma;''  be  supplied  to  the  soil  in  vary- 
ing quantities  depending  upon  its  clay  content.   This  treatment  has  a  tenden- 
cy to  make  the  soil  more  friable  and  easier  to  cultivate.   Tlie  application  of 
lime  to  sandy  soils  should  be  practiced  ver^'  sparingly  or  not  at  all.   It  may 
stimulate  growth  temporarily  but  later  retardation  of  plant  growth  often  oc- 
curs. Competent  advice  should  be  sought  before  using  lime  on  these  kinds  of 
gardeii  soils. 


-  p 


To  further  provide  a  proper  soil  environnent  for  plant  gruv/th,  some  sys- 
tem of  drainage  should  be  provided  to  carr^^  off  the  excess  surface  water  af- 
ter hea-vj-  rains  and  the  free  soil  water.   Tlie  underground  plant  parts  such  as 
roots,  'b-olbs,  etc.,  need  a  proper  air  supply  as  v;ell,  just  as  do  the  aerial 
growth  parts.  A  water-logged  soil  deprives  the  lower  plant  parts  of  a  proper 
air  supply,  and  a  retarded  growth  results.  Plants  utilize  the  water  held  by 
the  soil  particles  or  the  so-cailed  film  water.  Water  that  flows  freely  te- 
tween  the  soil  particles  should  be  allowed  to  drain  off  and  permit  a  proper 
circulation  of  soil  air  for  plant  respiration  and  bacterial  activity. 

Water  is  the  so-called  universal  solvent.   Tne  availability  and  utiliza- 
tion of  fertilizing  ma,terials  depend  upon  the  extent  to  which  such  materials 
are  dissolved  by  the  soil  water  and  thus  made  available  for  plant  growth. 
The  utilisation  of  fertilizing  materials  by  plants  can  be  realized  only 
through  an  adequate  \?ater  supply-  The  growth  behavior  of  different  plants  can 
be  controlled  by  proper  fertilization  only  to  the  extent  to  which  such  mate- 
rials are  made  available  to  plants  by  water.  Ve.'^etative  growth  is  often  stimr- 
tilated  through  higher  nitrogen  fertilization  supplemented  by  an  ample  water 
supply.  Flowering  and  seed  production  in  many  plants  is  bro'ught  about  not 
onljr  by  decreasing  the  supply  of  nitrogen  but  also  by  retarding  the  availa- 
bility of  such  nitrogen  by  diminishing  the  available  water.  Besides  facili- 
tating the  availability  of  plant  nutrients,  water  is  essential  for  the  va- 
rious metabolic  processes  that  taJce  place  within  the  plant.   The  transloca- 
tion and  assimilation  of  the  variou.s  plant  nutrients  within  the  plant  ai-e  per- 
formed in  a  soluble  forra  and  water  is  required  for  tlus  purpose.   To  further 
carry  on  these  processes  a  certain  turgidity  mast  be  maintained  within  the 
plant.   This  condition  is  brought  aboiit  by  maintaining  a  required  osmotic 
pressure  within  the  plant,  Without  an  available  water  supply  this  condition 
cannot  be  maintained.  Respiration  and  plio  to  synthesis  in  plants  require  a 
moist  surface  within  the  pore  spaces  of  the  leaves  for  the  absorption  of  oxy- 
gen and  carbon  dioxide.  Plants  in  a  wilted  or  semi-wilted  condition  are  un- 
able to  cariy  on  those  vital  processes  efficiently  and  therefore  are  retarded 
in  their  growth. 

The  various  requirements  for  water  by  plants  necessitate  some  form  of 
irrigation  to  furnish  them  with  the  needed  supply.   The  individxial  can  best 
judge  for  himself  what  form  of  water  supply  system  meets  his  needs.  Water 
should  never  be  applied  to  plants  in  quantities  beyond  their  growing  needs. 
Such  excess  results  in  surface  erosion  and  in  the  leaching  of  plant  nutrients 
from  the  soil  in  the  drainage  water.  Excessive  evaporation  of  water  from  the 
soil  surface  can  be  avoided  'oy   irrigating  garden  plants  din'ing  the  cooler 
part  of  the  day  v;hcn  such  evaporation  is  at  its  lowest.   Soil  moisture  can  be 
further  conserved  through  the  use  of  mulches  and  the  eradication  of  weeds^ 
Weeds  utilize  a  groat  part  of  the  soil  moisture  nccessarj'-  for  garden  plants, 
and  their  eradication  should  not  be  overlooked. 

Tile  fertilizers  to  be  used  for  gard  n  plants  depend  upon  the  kind  of 
plants  grown  and  the  stage  of  growth  at  which  such  plants  are  to  be  utilized. 
Besides  the  various  forms  of  anirrial  manure  used  for  garden  fertilization,  va- 
rious commercial  fertilisers  are  available,  both  in  the  organic  and  inorganifj 
form.   Hiosc  known  as  complete  fertilizers  gencrallj''  contain  the  three  chief 
fertilizing  constituents  —  nitrogen,  phosphorous,  and  potassium  —  in  various 
proportions  or  percentages. 


Siiiiilc  fertilizers  grncrallv  contain  one  of  thoso  constituents.   If  ne- 
cessary a  coinpl.:.tc  fortilizcr  high  in  nitrogen  should  be  incorporated  ^vith  the 
soil  "before  planting  or  shortlj^  after  the  plants  togin  to  prodv.co  top  grov/th. 
The  proccd-oro  to  he  followed  after  this  depends  "upon  the  kind  of  garden  plant 
and  tho  purpose  for  which  it  is  grown. 

Por  fertilizing  purposes,  ornamental  garden  plants  maj'-  he  divided  into 
four  classes: 


1.  Toliage  plants 

2.  Plowering  plants 
Pruiting  plants 
BuLhs  or  flcslij'  roots 


I 


Poliage  plants  maj''  ho  anmaals  or  perennials.  Hiesc  plants  are  grown  for 
their  leafage  or  foliage.   To  produce  this  kind  of  growth  they  must  he  irnpt 
in  a  vigorous  vegetative  growth  condition.  After  adding  a  complete  fertilizer 
early  in  the  season,  fertilizing  materials  high  in  nitrogen  should  he  applied, 
at  short  intervals  during  the  growing  season.  This  fertilization  should  al- 
ways be  accompanied  b;'-  a  sufficient  water  supply  to  make  siich  materials  avvl"/- 
able  to  the  plants.  Wliere  the  iron  content  of  the  soil  is  insufficient  for 
ample  photosynthetic  activity  in  the  plants,  a  light  application  of  coppeva'^ 
added  to  the  soil  in  the  form  of  a  thin  spray  will  be  helpful.   In  case  :! 
perennial  foliage  plants  nitrogen  fertilizers  should  not  be  applied  too  jato 
in  the  season  so  as  to  have  the  young  succulent  growth  killed  b?/  early  f.ve,5t. 
Fertilizers  lower  in  nitrogen  applied  du-ring  the  late  growing  season  will",  be 
stored  within  the  plants  and  result  in  early  vigorous  growth  the  following 
spring. 

To  bring  about  a  maximum  production  of  flowers  on  plants  a  certain  rela- 
tive organic  composition  of  the  plants  must  be  attained,  especially  betT-3-?n 
nitrogen  and  carbohydrate  compounds  in  the  parts  of  the  plants  where  such 
flowers  are  produced.  A  vigorous  vegetative  growth  should  be  attained  by 
these  plants  during  the  early  growing  season^   To  attain  this  condition  fer- 
tilizers rather  high  in  nitrogen  should  be  supplied  to  the  plants.   This  fer- 
tilization brings  about  an  abundant  leafage  for  the  elaboration  of  carbohy- 
drate materials  in  the  plants.  After  a  sufficient  size  of  plants  with  ah.n- 
dant  leafage  is  attained,  nitrogen  fertilization  with  its  accompanying  waver 
supply  should,  be  reduced.   Tliis  brings  about  a  lower  nitrogen  supply  to  tlie 
plants.   Tlie  continual  elaboration  of  carbohydrates  by  means  of  the  large  let-f 
area  results  in  a  high  carbohydrate  content  in  the  plants  in  relation  to  ni- 
trogen. This  composition  relation  is  associatei  with  reproduction  or  flower- 
ing in  such  plants.   If  all  other  factors  are  f-avorable  such  as  light,  tem^;era- 
ture,  moisture,  etc.,  aburivlant  flowering  will  take  place. 

To  keep  plants  in  a  flower  producing  stage,  flowers  should  not  be  per- 
mitted to  form  fraits  or  seeds.   Contintial  removal  of  flowers  before  fruit 
forma.tion  reverts  the  flo-^  or  bearing  parts  of  the  plants  to  a  vegetative  growvh 
condition,  and  the  plant  gradtially  grows  back  to  the  reproductive  or  floweri::^; 
stage.  After  fertilization  of  the  flowers  or  gar.ietic  union  in  flowering  pla-t-j^ 
the  plants  acquire  an  increased  capacit;r  for  absorbing  plant  nutrients,  'ihe 
process  of  reproduction  appears  to  stimulate  this  feeding  power  of  plants  vr^ 
to  the  time  of  fruit  formation.  Tlie  application  of  fertilizing  materials  not 
too  high  in  nitrogen  at  this  advanced  flowering  pei-iod  will  keep  plants  in  a 


U  - 


vigorous  grov/lh  condition  by  supplying  sufficient  mlnp.ra?.  nutrients  for 
ab'ojidcint  flov/er  production.  To  promote  this  increased  capacity  of  plants, 
fruit  forma.tion  inust  not  be  permitted  to  talre  place. 

TnThere  the  fruit  of  the  plant  is  sought  in  ornamental  garden  plants,  vi- 
gorous flowering  is  a  pre-requisite  for  such  fruit  production.  In  addition 
to  this,  the  plant  must  possess  a  stored  supply  of  organic  and  inorganic 
foods  so  as  to  develop  the  fruit  when  it  once  begins  to  form.  To  obtain  this 
condition  in  plants  they  should  be  fertilized  with  fertilizers  rather  high  in 
nitrogen  so  as  to  produce  vigorous  vegetative  parts  with  abundant  leafageo 
This  increased  leaf  area  is  needed  for  the  elaboration  of  organic  foods  bt■^- 
yond  the  growing  needs  of  the  plants.  These  excess  foods  are  stored  within 
the  plants  and  later  utilized  in  the  development  of  the  fruit.  As  in  the  case 
of  all  flowering  plants,  when  sufficient  vegetative  growth  is  produced  the  irl- 
trogen  supplied  to  the  plants  should  be  decreased.   This  with  a  slightly  de- 
creased water  supply  will  bring  the  jDlants  into  flowering  which  is  pre-requi- 
site to  fruit  production.  As  formerly  stated,  plants  have  an  increased  ab- 
sorbing power  for  soil  nutrients  after  fertilization  of  tlie  reproductive 
parts.  Commercial  fertilizer  applied  during  this  period  will  supply  the  plant 
with  abundant  nutrients  for  later  production  of  fruit.  After  fruit  formation 
occurs  translocation  of  plant  foods  to  ths  fruit  forming  areas  takes  placb 
within  the  plant.  If,  before  this  period  the  plants  have  been  properly  fer- 
tilized, well  formed  fruits  will  result. 

Tlie  fruit  wood  of  many  plants  is  formed  the  year  previous  to  fruit  forma- 
tion. After  reproduction  in  such  plants,  fertilization  v?ith  a  compiete  fer- 
tilizer stimulates  the  storage  of  plant  foods  and  the  production  of  fruit 
growing  areas  for  the  following  season.  During  the  late  growing  season  phos- 
phate and  potash  fertilization  furthers  the  storage  of  plant  foods  for  the  fol- 
lowing season.  High  nitrogen  fertilizers  at  this  time  keep  the  new  growth 
too  succulent  and  susceptible  to  frost  injury. 

Plants  grown  for  the  production  of  bulbs  or  flesh.y  roots  sliould  be  ferti- 
lized so  as  to  stimulate  the  grov/th  of  the  underground  plaiit  parts.  Ferti- 
lizers applied  to  such  plants  should  be  his^i  in  soluble  phosphorus.  Tliis  ele- 
ment has  a  tendency  to  increase  root  or  bu.i.b  production  on  these  plants.  Early 
vigorous  vegetative  growth  is  essential  for  the  production  of  a  large  top 
growth  with  sufficient  leafage.  Roots  and  bulbs  require  the  elaboration  of 
large  quantities  of  organic  ms,terials,  especially  carbohydrates.   Therefore 
an  abiuidant  leafage  is  essential  for  this  purpose.  Mtrogen  fertilization 
early  in  the  season  is  necessary  for  a  good  top  growth,  fertilizers  applied 
later  should  be  lower  in  nitrogen  and  higher  in  phosphorus.  Where  sugarr.  f'ji-m 
a  large  part  of  the  materials  in  bulbs  and  roots,  potassium  is  ver;;;  essentia"^, 
for  their  elaboration.  Fertilizers  applied  after  early  growth  should  har^,  \hii 
element  increased  in  their  mixture. 

To  summarize  briefly,  garden  soils  should  be  high  in  organic  matter  con- 
tent, they  sliould  be  well  drained  and  adequately  watered.  As  to  fertilizers, 
let  us  keep  in  mind  that  after  applying  a  general  commercial  fertilizer  earl"^ 
in  the  season  fertilizers  high  in  nitrogen  will  produce  vigorous  growth  arf. 
fine  foliage.  If  the  plants  are  growA  for  flowers  or  fruit  they  should  firs  ■■ 
be  rnade  to  grow  off  vigorously,  and  then  the  nitrogen  content  of  the  ferti- 
lizer should  be  reduced.  For  bulbs,  fertilizers  higli  in  phosphorus  are  best.

G-ABDEiaiTG  LITEEATUEE 
By  -  Mrs.  Id-"  Keeling  Cresrp,  libr^ri-'n 
rioridr  Experiment  St'^.tion 

T;.ie  liter-^ture  of  orn^mentpl  g-irdening  h^s  h'd  ",  difficult  time  to  come 
into  its  own.  It  hrs  been  hidden  under  rll  sorts  of  subjects  "nd  only  within 
the  lT.st  cjU'-^rter  of  n  century  hrs  it  been  brought  out  into  the  light  of  dry  to 
develop  in  its  own  impor truce. 

It  is  possible  thr^t  long  before  the  -^dvent  of  the  book  in  the  forn  of 
cl'y  tablet  or  roll  of  p-^pyrus,  mm  prrcxiced  some  sort  of  orn'-'ment-'d  garden- 
ing. Ve   kiaow  th'-^t  he  hnd  laiovrledge  of  pl-^nts,  ^iid.  he  lipd  '"'   certain  love  of 
beauty  's  is  evidenced  ^oy   the  pictures  r  ipped  in  stone  th^t  hpve  been  dis- 
covered from  time  to  time  by  ^rchf'.eologists  in  their  exC'-^vtions.  Orn^mentr- 
tion  of  the  body  w-^.s  evident,  out  whether  this  extended  to  m-^n's  surroundings 
we  do  not  kiio?v. 

Clpy  trblets  ?,nd  papyrus  rolls  were  used  for  records  in  nncient  times 
to  ^.   cert'^ii:.  extent,  but  it  wis  not  until  the  15th  century  when  the  Germria 
Gutenberg  invented  the  method  by  which  p.-'per  could  be  printed  from  mov^.ble 
blocks  in  r  printing  press,  that  n  literp,ture  on  -nj'-  subject  wrs  r.ssured.  Al- 
most immedirtely  it  developed  th-^'t  m-T.^'  people  h'^xl  the  urge  to  write  so  th-^t 
with  the  p-'-ssing  of  the  ye-^rs  the  world  hns  become  fairly  well  stocked  with 
good,  b^d  ^nd  indifferent  books. 

Up  to  this  time  -"^ll  the  gardens  h.^d  been  n=>de  following  f   severely  for- 
mal style.  Tney  T;ere  plr^nned  j-nd  I'id  out  with  geoi: '.^tric^l  precision.  This 
Wf>s  true  to  such  rn   extent  th-t  in  172S  B.-tty  L^r;-"  y,  in  •",  book  on  "Hew  Prin- 
ciples of  G-rdening,"  devoted  ^11  of  P^rt  I  to  geometry.   "Eie  el-'bor^te  de- 
signs r>nd  figures  could  be  secured  only  by  the  nost  careful  computJ^tion. 

Tliis  type  of  g-^rden  hnd  existed  for  so  long  thr^t  gr-^du'^lly  it  became 
irksome  to  those  people  v/ho  longed  for  ^  more  n'^tur-^l  '■rr^ngement .  Pin.-^lly, 
the  poets  ''lid  p-^inters  beg'^n  to  m'-ke  v/ritten  r^nd  p-^inted  fppe'^ls  for  less  Tti  - 
fici-"lity  '^nd  more  n^tur'^l  beauty.  Milton,  Pope,  Xddison  r^nd   the  Dutch  pr>in*ers 
becme  insistent  for  this  chrnge  in  orn-'-ment'^l  plantings  '"nd  planning. 

In  176U  Willirm  Shenstone  in  "Unconnected  Tliouglits  on  Gardening"  wrote: 
"Grrdeni^ig  mf^y  ^e  divided  into  three  species  —  kitchen-gardening  -  p-rterre- 
g-rdening  -  --nd  Irndskip,  or  picturesque-g-^rdening.  Tlie  letter  tj.-pe  is  the 
one  in  which  we  -''.re  most  interested.  It  consists  in  pie-sing  the  im-'^gin-'^tion 
by  scenes  of  gr-^^ndeur,  beauty  or  variety.   Convenience  merely  h'-s  no  sh-'^re 
here;  f^r^y  f-rther  th-'^n  rs   it  pleases  the  im-^.gin'-tion."   It  is  believed  th-t  in 
this  writing  of  Shenstone  origin-ted  the  term  "l-ndsc-pe  g'-rdening."  It  would 


-  2  - 


seem  to  me  thrt  in  his  expression  "picturesque  garden"  he  h'^s  ''.Iso  been  respon- 
sible for  our  modern  "ornr-ment'-l  g'-rden"  for  ^n  orn'^ment-'^l  grrden  worthy  of  the 
nnme  certainly  mast  he  picturesque.

In  Shenstone's  ovm  be"utiful  garden,   engr'-ved  on  ->.  t^^blet,   were  these 

• 

"Here  in  cool  grot  rnd  mossy  cell. 
We  rur'^.l  frys  r-nd  f?>eries  dwell; 
Tho  rarely  seen  by  mort-^l  eye, 
Hilhen  the  p-'le  moon,  ascending  high, 
Dr.rts  thini  yon  limes  her  quivering  be«ms, 
We  frisk  it  near  these  cryst^^l  streams." 

Ti:n.t  r.  berutiful  picture  this  brings  to  mind  ^^nd  how  suggestive  of  m 
iderl  Florid?  garden! 

It  v^s  some  time  before  the  idep  advanced  t;  the  poets  for  picturesque 
gardens  sprerd  through  E'arope.  M'^ny  people  persisted  in  continuing  a  practice 
about  which  Bacon  hrid  written  over  r   century  before:  "As  for  the  mpMng  of 
Knots  or  Figures,  with  divers  Colored  E'rths,  they  be  but  toys,  you  m'^y  see  as 
good  sight  mrny  times  in  Tarts  ...  I  do  not  like  Im^^ges  cut  out  of  Juniper,  or 
other  g'-rden- stuff;  they  are  for  Children." 

The  grrden  based  on  the  elaborate  geometrical  design  was  doomed,  and 
while  its  imiredi-'^te  successor  was  different  from  the  g-Tden  of  todP^r,  it  was 
gradually  approaching  it. 

It  is  a  str?nge  f-ct  that  much  if  not  most  of  our  early  horticultural 
literature  wrs  written  by  persons  who  hrd  no  pri-rrry  interest  in  horticulture. 
I  have  already  commented  on  the  part  pl-^yed  "oy   the  poets  rnd  pr^inters  in  chf-ng- 
ing  the  form  of  the  garden.  It  remained  for  the  physici'-^n  "nd  n^tur-list  to 
give  the  world  first  knowledge  of  plants  -nd  pl-'jiit  life.  The   old  "Herb-'ls" 
written  by  them  J^re  of  immense  import-'^nce. 

It  ws  the  physician  '^nd  the  n5«turalist  who  were  first  interested  in  the 
pl.-nt  life  of  America.  One  of  the  e-rliest  known  AmeriC'-^n  writers  to  list 
plants  from  Ingl-'-nd  th'^t  would  or  i;70uld  not  grow  in  this  country  w?^s  John  Jos- 
selyn.  In  I672  he  published  v   book  entitled:   "ITew  England's  R.-^rities  Dis- 
covered in  Birds,  Beasts,  Fishes,  Sei-pents,  -nd  Pl--nts  of  the  Country."  His 
list  of  pl-nts  consisted  of  '.n  rissortLient  of  veget'^bles  -nd  flowers,  including 
with  C'lbb-'ge  r>nd  lettuce,  the  hollyhock,  gilly  floiTsr,  marygold  (spelled  m---ry- 
g-ol-d)  -^iid  he  comments  that  rosemar:,^  will  not  survive  there.   This  is  the  only 
authentic  account  of  vvh'-t  grew  in  those  e^rly  llew  Engl-"nd  gardens. 

In  1791  Willinm  B-^rtr-'m  published  his:  "Tr.-vjls  through  ITorth  ajid  South 
Cnrolina,  Georgi-'^,  E-^st  -^nd  West  Florida."  B^rtr-ra  w-^.s  -->  n-'^tur'^list  <-nd  he 
visited  these  st'-^tes  for  the  purpose  of  collecting  plr'nts.  His  list  of  plants 
found  growing  in  Florida  was  the  first  one  to  be  published.   It  is  '^n   iraport-^nt 
contribution  to  the  e^rly  pl-nt  literature  of  the  st-te  rnd  South. 


-  3  - 

In  his  "ITew  Cyclopedi-"  of  American  Horticulture,"  L.  H.  Bailey  descritea 
the  colonial  gardens  most  interestingly.  He  writes:  "The   colonial  orn^ment'-^l 
gardens  were  unlike  our  own  in  the  rel'^tive  poverty  of  pl-^nts,  in  the  ''.hsence 
of  the  ly^ndsc^-pe  •'^rrnngement,  in  the  rarity  of  greenliouses,  '^nd  the  lo.ck  of 
smooth-sh-^ven  Irwns  (for  the  Inmi  mower  w^s  not  iu.  3".-.ted  till  this  century)." 
He  gives  r  brief  description  of  the  privte  g-^rden  of  Governor  Peter  Stuj'ves^'nt 
of  ITew  Amsterdam  (now  ITew  York)  which  the  Governor  c-lled  the  "Bouwerie."  It 
required  kO   or  50  negro  slr.ves  f^nd  several  white  servants  to  c«^.re  for  it.  The 
site  of  th-^t  frmous  old  garden  is  the  location  of  ITew  York's  "Bowery"  of  todry 
—  truly  r.   grert  ch-"nge. 

TIae  Bulletin  of  the  Grrden  Cluh  of  America  is  replete  with  -Tticles  r- 
bout  the  g-^rden.   One  in  p-^rticulrr  of  special  interest  ^;^s   published  in  the 
September  1928  number  of  the  Bulletin.   It  w^s  "Colonir-l  Grrdens,"  by  Rr'.chel 
McM.  M.  Hunt.  One  interested  in  Florid^  gardens  should  rc^d  it. 

With  the  beginning  of  the  19th  century  -'.  number  of  American  books  on 
••agriculture  beg'ii  to  be  published.   The  tern  "agriculture"  wns  inclusive  of 
horticulture,  riid.   floricultiire  or  grrdening  usu-^lly  were  given  some  mention. 
In  ISOU,  John  Gr.rdiner  "nd  Df^.vid  Hepburn  published  -t  W'shington,  D.  C,  r^   very 
smrll  book,  measuring  only  four  by  six  inches,  entitled:  "Tlie  American  G-^rden- 
er,  containing  -^mple  directions  for  working  r>.  Kitchen  G'-^-rden,  ever5'-  month  in 
the  yep,r;  pnd  copious  instructions  for  the  cultivr-tion  of  Flower  Grrdens,  Vine- 
yards, ioirseries,  Hop-Y^rds,  Green  Houses,  pnd  Hot  Houses ."  Tlie  authors  cer- 
tninly  wrnted  to  cover  everything  while  they  were  r.t  it. 

Another  example  of  including  inform^.tion  nbout  vegetrbles,  orn.-^mentrls 
or  floriculture  is  shown  in  a  book  published  in  1823  "^Y  Willi?m  Cobbett;  "Tiie 
American  G'-.rdener.  A  treatise  on  the  situ-tiou,  soil,  fencing  y'lid  l.-^ying  out 
of  g.-^xdens;  on  the  m?>king  and  mpjirging  of  hot  bc^ds  rnd  greenliouses,  pnd  on  the 
propagation  rnd  cultiv^.tion  of  the  several  sorts  of  vegetr.bles,  herbs,  fruits 
pjid  flowers." 

Tiie   first  gre'>,t  l-ndscrpe  grxdener  of  Americ:  wns  Andrew  J?.ckson  Down- 
ing. He  \7as  born  nt  Hewburg,  IT.  Y.,  on  October  30,  1S15  rnd  died  by  drowning 
on  July  2S,  1852.   In  iSUl  he  published:  "Trertise  on  the  Tneory  -"nd  Pr-ctice 
of  L.-ndsc-pe  G-rdening  -nd  Cottrge  Residences."  Pour  ye.-rs  1-ter  he  published: 
"Fruits  '^nd  Fruit  Trees  of  Americr.."  Tlie  I'-tter  is  credited  with  aborting  more 
influence  in  arousing  the  interest  of  people  in  fruit  growing  tl:^j.i  --^11  other 
books  i.t  th.-t  time.  After  the  Author's  derth  it  r.-^s  continued  '^nd  sever^-l 
times  revised  by  his  elder  brother,  Ch-'rles  Downing. 

It  w-'S  not  until  1223  th-t  ^   writer  published  a  book  devoted  exclusively 
to  flowers.   Tl-.is  wrs  Rol^^nd  Green's  "Treatise  on  the  Cultivation  of  Flov.'ers." 
It  W--S  follov^ed  in  IS39  by  the  first  Americ-n  book  devoted  to  one  flower.   Tl'-is 
wrs  published  by  Snyers  '"nd  v.fs  p.  treatise  on  the  dnhli^". 

F.-.ile  the  horticultur-"l  book  w^s  of  £:re-t  inrport-nce  to  the  gardener, 
during  the  last  fifty  years  of  the  19th  century  it  w-s  the  agricultural  mi^ga- 
zine  th-^t  proved  the  most  helpful.

PLANT  imBS,   WHEHCS  DERI7ED  AITO  T7HAT  THEY  MEAN 

By  -  Erdrnan  West,  Mycologist 
Florida  Agricultural  Experiment  Station 


For  the  past  six  weeks  our  fence  rows,  woods  and  many  of  our  gardens  have 
"been  gay  with  a  native  shrub  bearing  dense  clusters  of  brilliant  purple  berries. 
Many  of  my  audience  will  recognize  it  at  once.  TTlj-at  is  its  namef  ''Tell,  the 
popular  name  is  French  Mulberry.  B^it  the  botany  books  say  it  is  a  native  of 
America  and  does  not  occur  in  Prance.  Further,  they  do  not  classify  it  among  the 
mulberries.  Then  what  do  they  call  it?  The  scientific  name  or  botanical  naue  :.s 
Callicarpa  americana.   But  you  say  "Botanical  names  are  so  difficult.  And  they 
don't  mean  anything  to  me."  Perhaps  a  little  explanation  of  the  form  and 
derivation  of  botanical  names  will  help  us  to  appreciate  them. 

Many  other  popular  names  are  just  as  misleading  as  the  one  just  mentioned. 
Spanish  moss  is  neither  a  moss  nor  Spnnish,  being  closely  related  to  the  pireappio, 
Corn  in  the  United  States  means  something  entirely  different  from  corn  in  England. 
A  few  popular  common  names,  however,  are  used  consistently  and  mean  definite 
plants,  as  Cherokee  Rose  r;id  live  oak.  Many  others  are  very  ambiguous.  Papaw 
may  mean  either  one  of  tv/o  very  different  plants.  The  term  "bay"  is  applied  zo   zu 
many  different  plants  that  I  will  not  attempt  to  list  them..  Moreover,  no  English 
popular  name  would  be  understood  in  Russia  or  France  or  Japan.  The  object i.ons  to 
popular  names  then  are  that  they  are  indefinite  and  not  widely  understood. 

The  use  of  Latin  binomials  to  designate  plants  dates  from  the  time  of 
Linnaeus  about  1753 •  Up  to  the  time  of  this  great  Swedish  naturalist,  plantii  had 
been  studied  and  described  principally  for  their  reputed  medicinal  propertie:;. 
Close  relationships  araorg  them  had  been  recognized  arii  related  plants  had  bs'^.n 
grouped  under  a  common  name.  For  instance,  all  roses  were  grouped  under  "Hoija", 
the  Latin  word  for  rose.  The  various  kinds  of  roses  were  distingui.^hed  oy  shcrt 
descriptions.   Sincd  Latin  was  the  common  classical  lang^oage  of  the  period,  ■(ihe-'-'e 
descriptions  also  were  in  Latin.  Linnaeus  hit  upon  the  happy  plan  of  design'/iiiitf 
each  kind  by  one  Latin  adjective  in  addition  to  the  group  name.  A  white  roso  u:'.' 

i-^.nnaeus'  time,  he  catalogued  as  Rosa  alba  and  followed  thio  with  a  desc.ip'../. T 

''■be  plejit.  Piper  was  the  Latin  word  for  pepper  and  so  the  plant  that  produced  th- 
black  pepper  of  commerce  became  Piper  nig  roan,  followed  by  the  complete  descilpci'.... 
of  the  plant . 


Probably  Linnaeus  did  not  intend  this  combination  to-be  the  name  of  the  plar . 
when  he  first  used  it.  He  was  resorting  to  it  merely  as  an  indicator  to  save  zr.p 
trouble  of  reading  through  each  entire  description.  However,  it  soon  became 
customary  to  refer  to  a  plaiit  by  this  combination  without  appending  the  descriptic. 
and  thus  the  binomial  system,  as  it  i  s  called,  was  established.  Sir:ce  then? 
attempts  have  been  made  to  extend  the  combination  to  ^ncxuce  three  or  mors  names, 


but  the  two'-name  combination  has  he^-one   established  throughout  the  '.Torld  for  the 
•scientific  designation  of  plants  and  animals.   Certain  codes  of  rules  have  been 
established  for  the  formation  of  these  names  both  in  A-nerica  and  Europe, 
differing  in  minor  respects  but  agreeir^  for  the  most  part. 

The  botanical  name  of  a  plant,  then,  consists  of  two  definite  parts.  The 
first  part  of  the  combination,  as  we  have  seen,  indicates  the  group  or  genus  to 
which  the  plant  belongs.  The  second  name  tells  the  s-pecj-es  or  particular  kind 
in  the  genus.  Thus  Linnaeiis'  white  rose  was  Hosa  alba.  The  nruiie  Rosa  indicates 
the  affinity  of  the  plant  with  all  the  other  roses.  The  alba  part  of  the  name 
distinguishes  it  from  all  the  others  in  the  group.  So  all  the  different  ros-^^s 
would  have  Hosa  for  the  f:".rst  part  of  the  name.  The   second  or  specific  part  of 
the  name  indicates  the  individual  i;ind  of  rose.  Rosa  sinensis  is  a  Chinese  rose, 
because  sinensis  in  Latin  means  Chinese.  Rosa  Carolina  is  a  rose  from  Carolina, 
Rosa  lancifolia  is  a  rose  with  lance-shaped  le;:.ves. 

In  the  beginning,  the  generic  names  were  the  Latin  names  for  the  plants  bu- 
as  new  plants  were  found  or  described,  new  genus  names  had  to  be  found  for  the 
various  groups  that  were  discovered.   Sometimes  the  name  of  the  man  who  discovei'cd 
the  plant  was  used  as  a  basis  after  being  Latinized.  Generic  names  vieve   frecr^ientl;. 
coined  to  honor  famous  botanists  or  patrons.   Thus,  the  stiiikring  cedar  of  the 
Chattahoochee  River  has  the  genus  nai'ne  Torreya  commemorating  the  famous  American 
botanist  Doctor  Torrey.  The  banana  sbrub  has  the  genus  name  Michelia  to 
memorialize  the  famous  Italian  botanist,  Peter  Michel, 

Old  C-reek  names  were  also  used  after  being  Latinized.  The  name  of  the 
I'rench  mulberry  to  which  we  referred  earlier  is  an  excellent  example.  The 
botanical  name,  you  remember,  is  Crillicarga  americana.   Callicarpa  comes  from  two 
G-reek  words  meaning  beauty  and  fruit.  So  Callicarpa  means  beauty  fruit.  America? 
is  a  Latin  adjective  meaning  America  i.  A  free  translation  of  the  whole  Latin  nanc 
would  be  American  Beauty  Berry,  which  is  far  more  appropriate  than  French  Mulberr-; 
the  popular  name  it  bears.   The  tulip  tree  or  tulip  poplar j  Liriodendron,  comes 
from  two  G-reek  words  meaning  tulip  and  tree.   Many  modern  generic  names  are  forme; 
by  taking  some  Sreek  word  or  combination  of  words  thcit  indicate  an  outstanding 
characteristic  of  the  group  and  using  it  for  the  generic  name.  For  instance, 
Cereus  is  the  name  of  a  genus  of  cacti,  while  Nyctocereus  is  a  closely  related 
genus  the  members  of  which  bloom  at  night.  Sycto  couc-s  from  a  Greek  word  meaning 
night.  Another  exainple  is  the  forget-me-not,  Hyosotis.  This  generic  name  comep 
from  two  Greek  words  which  mean  moiise  and  ear,  and  was  applied  to  this  plant 
because  the  leaves  resemble  the  ears  of  a  mouse  in  shape.   The  derivation  ar.l 
meaning  of  most  generic  i.araes  are  given  in  such  books  as  Bailey's  "Cyclopedia  cf 
Horticulture"  and  Gray's  "Manual  of  3otan^/." 

The  second  part  of  the  binomial,  the  specific  name,  is  frequently 
•'.escriptive  in  character.  Quite  often  the  specific  name  is  a  Latin  or 
Latinized  Greek  descriptive  adjective.  For  instance,  the  summer  grape  is  Vitis 
aestivalis ,  Vitis  being  the  classical  name  for  grape  and  aesti-valis  meanir.g 
summer;  the  potato  is  Solaxi^am  tuberosum,  the  tuberosum  part  of  the  name  referr;-.:).; 
to  the  fleshy  tubers. 

Many  specific  names  are  derived  from  the  countr:/  of  origin  of  the  plant. 
Thus  we  get  Citrus  sinensis,  meaning  the  citrus  from  China;  Azalea  indica,  the 
azalea  of  India;  and  Fraxinum  americana,  the  Fraxinum  or  ash  of  An-ierica. 


-3- 


Other  specific  names  indicate  the  habitat  of  \.iie  plant.  Pirms^  Tjalustris 
is  the  pine  of  the  sv/araps;  Aleurites  nontana  is  the  Aleurites  on  the  mountains, 
and  so  on. 

Very  frequently,  the  specific  nan:e  honors  the  collector  or  discoverer  of 
the  plant.  Phlox  Druramondii  thus  honors  Druramond;  and  Que  reus  Michauxii  was  named 
for  Andre  L'ichaux  who  found  this  oak. 

In  contrast  to  my  earlier  comments  concerning  common  names,  let  me  draw  your 
attention  to  how  appropriate  some  botanical  names  are.   In  v;estern  Florida  aud 
further  north  is  a  small  plant,  hugging  the  earth  at  all  times  and  perfuming  the 
air  in  spring.   Its  comni.on  name  is  Trailing  Arbutus.  Botanists  call  it  EpijErea 
regens  which  literally  translated  means  "creeping  upon  the  earth"  and  describes 
perfectly  the  habit  of  this  beautif-'ol  little  wild  flower.  Another  particularly 
apt  name  is  that  of  the  common  flame  vine  that  covers  buildings  with  its  fiery 
orange  red  blooms  in  spring.   The  botanical  name  Pyrostegia  venusta  means 
beautiful  fiery  roof. 

There  is  a  third  part  of  the  botanical  name  of  a  plant  that  is  important  anl 
interestirg  too.  This  is  the  name  or  initials  that  follow  the  genus  and  species 
name,  as  in  the  botanical  name  of  the  mango,  Mangifera  indica  L.  This  L.  stands 
for  Linnaeus  and  indicates  that  the  scientist  Linnaeus  first  gave  the  mango  this 
scientific  name.   Sometimes,  there  are  two  names  following  the  specific  name, 
one  of  them  in  parentheses,  such  as  Wisteria  f rutescens  (L^)   Poiret,  with  the  L 
in  parentheses.  This  means  that  Linnaeus  first  described  the  plant  and  gave  it 
the  name  f rutescens  but  put  it  in  som6  other  genus  than  Wisteria.  Poiret  later 
examined  the  plant  and  decided  its  affinities  were  vdth  wisteria  and  put  it  in 
that  genus,  so  we  get  the  present  name.  T^iat  a  sroty  this  little  botanical  name

The  pronunciation  of  botanical  names  is  another  bugbear  for  many  gardeners. 
Anyone  who  has  had  an  introduction  to  Latin  should  have  no  trouble  with 
botanical  names.  Many  books  on  the  classification  of  plants  give  simple  direc- 
tions for  pronouncing  the  names.  While  on  this  subject,  I  might  mention  some 
common  plants,  the  names  of  which  are  often  mispronounced.  Many  people  say 
Ca-me-lia  for  Ca-mell-ia;  Pitt-o-sporum  for  Pit-tos-porum;  Sto-ke-sia  for 
Stokes-ia;  and  Ag-er-a~tum  for  i,*»ger~atum 

A  very  delightful  treatise  on  this  subject  of  plant  names  has  been 
published  recently  by  the  Macmillan  Company.   It  is  "How  Plants  Get  Their  Names," 
by  L.H.  Bailey.   In  it  you  will  find  a  more  complete  discussion  of  the  deri;:  t\:r-: 
It  includes  an  appendix  giving  the  meanings  of  most  specific  names,  and  a  guile 
to  the  pronunciation. 

Botanical  names  have  other  advantages  which  I  have  hinted  at  previously. 
A  botanical  name  is  definite  in  its  meaning.   Common  names  may  be  very  local  in 
their  application  and  several  may  be  applied  to  the  same  plant  in  different  pla^-: 
but  a  botanical  name,  with  few  exceptions,  is  always  the  same  and  refers  to  a 
single  kind  of  plant.  Moreover,  being  written  in  Latin  it  can  be  understood  by 
botanists  anywhere  in  the  world.   'Che  botanical  name  of  a  plant  is  the  same  the 
world  over,  no  matter  what  nationality  may  be  using  it. 


-Il- 


With  these  practical  advantages  in  favor  of  the  Latin  names  of  plants,  it 
seems  desirable  to  learn  and  to  use  them.  This  is  especially  true  when  v;e 
consider  the  meanings  of  the  names,  their  aptness  to  the  plants  they  designate 
or  the  associations  they  "bear  to  eminent  botanists,  intrepid  explorers  and 
other  famous  men.  Really  we  are  missing  part  of  the  pleasure  of  laiowirg  our 
plant  friends  when  we  do  not  Icnow  their  real  names  and  hov/  they  received  them. 
A  little  time  with  some  botanical  book  such  as  Gray's  Manual  or  Bailey's 
Cyclopedia  of  Horticulture,  will  open  a  new  field  of  pleasure.  Or  the  author 
of  this  paper  will  be  glad  to  help  you  if  you  willv write  him.

AITITUAL  FL0T7ERI1IG  PLANTS  FOR  THE  WINTER  AND  SPRING 

GARTEN 
By:  John  V.  Watkins,  Assistant  Horticulturist, 
University  of  Florida  College  of  Agriculture 

Bj'  far  the  greatest  variety  of  annurlc  that  we  enjoy  in  Florida  be- 
long to  the  cool-'-'feather  group  that  blossom  in  the  mnter  and  early 
spring.  The  number  of  kinds  tlis.t  fall  into  this  already  long  list  are 
increasing  each  year  as  new  sorts  are  being  introduced  by  the  seed 
houses.   In  addition  to  giving  us  new  sorts,  plant  breeders  have  been 
constantly  improving  the  old  and  tried  species.  Larkspur,  nasturtiurr^, 
snapdragons,  calendulas,  California  poppies  and  petunias  are  some  of 
the  old  favorites  that  have  been  vastly  improved  in  size,  color,  sub- 
stance and  design  during  the  past  few  years. 

The  cool -weather  annuals  that  bloom  in  the  winter  and  early  spring 
are,  for  the  most  part,  cold-tolerant,  and  unless  extremely  low  tem- 
peratures are  experienced  they  will  thrive  during  the  months  of  October 
through  April. 

Ifeny  successful  gardeners  make  their  first  plantings  of  the  winter- 
blooming  kinds  in  late  Augu.st  and  early  September,  at  first  protecting 
the  tender  seedlings  from  the  direct  rays  of  the  sun  by  shades  of  cloth, 
dog  fennel,  moss,  etc.,  unti?.  they  have  become  sufficiently  robust  to 
grow,  \anshaded,  in  the  open.  Som.e  of  the  late  spring  blooming  annuals 
will  not  germinate  i,7ell  during  hot  weather  and  it  is  necessary,  there- 
fore, to  wait  until  November  to  sow  the  seed  of  this  general  group. 

The  following  lists  may  be  helpf'^ol  in  regard  to  planting  time: 

Annuals  that  may  be  started  in  A"iagust  or  September  include  Alyssum, 
Babys '  Breath,  Blanket  Flower,  Blue  .3yed  African  daisy,  Calendiila, 
Chinese  Forget-me-not,  Lobelia,  Lupine,  iioroccan  toad  flax,  Kastuctium, 
Pansy,  Petunia,  Phlox,  Pinks,  Sna.pdragon,  and  Sweet  Pea. 

Annuals  that  may  be  started  in  November  for  late  winter  or  early 
spring  bloom  inclxide  Alyssujn,  Babj'-s'  Breath,  Butterfly  Flower,  Cali- 
fornia Poppy,  Candytti-ft,  Carnation,  Cornflower,  Double  English  Daisy, 
Hunnemania,  Larkspur,  Leptosjme,  Lupine,   ••'igvionette,  Nicotiana,  Orange 
African  Daisy,  Painted  Tongue,  Poppies,  Scarlet  Flaix,  Statice,  and. 
Stocks, 

In  those  varieties  there  is  room  for  wide  choice  as  to  color  and 
kind  of  flowers.  Discussing  some  of  the  leading  ones,  let's  take 
Alyssum  first. 


2  - 


The  several  varieties  of  S-zeet  Alyssiim,  with  white  or  lilac  flowers, 
are  among  the  best  of  aimuels  for  ecging  and  for  planting  in  the  rock 
garden.  Low  grooving,  seldon  exceeding  a  height  of  12  inches,  this  plant 
should  have  a  place  in  everj''  garden,  window  box  or  hanging  basket. 

Babys'  Breath.  The  irhite,  rose  or  carmine  flo7;ers  of  the  three 
varieties  of  babys'  breath  are  especially  valuable  in  flower  arrange- 
ments; particularly  is  this  true  if  sturdy  flowers,  such  as  bla^nket 
flowers,  dv;arf  sunflowers,  carnations  or  pinks,  are  the  principal  subject 
of  the  bouquet.  The  tiny  flowers  on  wiry  stems  add  a  daintiness,  a 
softness,  to  an  arrangement  that  might  be  somewhat  stiff  and  lacking 
in  gracefulness. 

Blanket  Flower.  The  annual  forms  of  the  blanket  flower,  single, 
semi-double  and  full  double,  are  of  great  value  in  any  garden.  The  red 
and  yellow  daisy-like  blossoms  are  desirable  for  cutting  on  account  of 
their  cheerful  colors,  long  stiff  stems,  and  excellent  keeping  quality, 

Blue-Eyed  African  Daisy.  Oracefvl,  light  blue,  daisy-like  flowers 
about  2^   inches  across,  v/ith  steel  blu.e  centers,  are  profusely  borne  by 
these  plants.  Tliis  daisy  is  one  of  the  n-.ost  easily  grown  of  the  hardy 
annuals  and,  like  the  blarlcet  flower,  it  succeeds  in  trying  situations, 

volunteering  each  year. 

Calendula.  A  universal  favorite,  the  calendula  is  one  of  our  most 
important  winter-blooming  anmvils.  The  charming  double  flowers  in 
shades  of  orange  and  yellow  are  not  only  excellent  as  part  of  the  garden 
picture  but  they  are  ■'onsurpassed  as  cut  flo^Ters. 

California  Poppy.  This  is  especially  effective  when  gro'Tn  in  large 
groups  in  a  sunny  garden.  F.ecentlj-  the  seedmen  have  offered  varieties 
in  creams,  white  and  reds,  tlir.t  are  striking  deviations  from  the  typical 
yellows. 

Calliopsis  (Cal"  li  op'  sis).  The  Calliopsis  or  coreopsis  is 
another  type  of  the  nijunorous  daisy-like  flowers  that  play  so  important 
a  part  in  an  annual  boi-ier.  The  flo-'ers  in  shades  of  yellow,  some  va- 
rieties with  maroon  or  terra,  cotta,  are  borne  in  profusion  on  stiff, 
wiry  stems,  and  a.re  valijaole  both  in  the  garden  and  in  bouquets. 

Carr^tion.  The  hybrid  ann-uAl  carnations  which  have  recently  been 
developed  by  plant  breeders  will  supply  everj'thing  save  size,  for  which 
the  perfect  florist  carnations  are  prized. 

Cornflower.  This  lias  long  been  a  favorite  and  somehow  seems 
characteristic  of  the  old-fashioned  garden.  The  single  and  double 
flowers  of  white,  pirik,  red,  blue  and  purple,  borne  in  profusion  in  ear- 
ly spring,  contribute  beautiful  clear  colors  to  the  border  and  are  ex- 
cellent for  cutting. 

Double  English  Daisy.  Although  the  English  Daisy  (or  Bel lis)  is 
really  a  perennial,  in  Florida  it  will  not  thrive  after  the  advent  of 
warm  v/eather  in  Ifey,  and  is  grov-in   as  a  winter  annual  so  that  it  may  en- 
joy the  cool  growing  season.  For  edgings  or  for  rock  gardens,  the  Eng- 
lish Daisy  is  excellent.  The  :_^lants  are  merely  flat,  tight  rosettes  of 


■i ,;.  i-. 


i.:\..

shining  green  leaves  froni  which  the  flo-jer  stems  arise. 

G-ilia  (Gil'  ia) .  Anotlier  blue  flo'-rer  of  merit  that  blooiris  in  the 
late  spring  is  Gilia.  The  foliage  is  lace.7,  fern-like  and  is  an  at- 
tractive feature  in  itself.  The  flcvers  are  rough,  globular  heads,  a- 
bout  an  inch  in  diameter  and  are  borne  in  profusion  all  over  the  plant. 
As  yet  something  of  a  novelty  in  Florida,  the  gilia  has  proven  its  a- 
bilitj,'-  to  thrive  here  end  should  be  tried  in  everyone's  garden. 

Godetia  (Go  de'  sha) .  Although  the  Godetia,  or  satin-flower,  like 
the  Gilia,  is  not  often  seen  it  will  succeed  in  Florida,  especially  in 
a.  partially  shaded  situation,  and  it  undoubtedly  deserves  consideration 
as  a  spring  flowering  annual. 

nunneniania.  The  h'onnernania,  sometimes  called  tulijj  poppy,  resem- 
bles a  sulphur-yellow  California  poppy  of  giant  size,  is  coarser  and  of 
greater  substa,nce.  The  plants,  about  tv/o  feet  in  height,  are  very  pro- 
lific, hardy  and  easy  of  culture  after  germination.  Difficiilty  in  c^-t- 
ting  a  good  sta,nd  is  the  general  rule. 

Larkspur.  The  well-knowii  Larkspur  is  so  popular,  so  widely  grown, 
that  it  seems  hardly  necessar:-  to  clo?-cribe  this  most  valuable  annua.l.. 
Single  and  double  flowers  of  white,  ouff,  rose,  blue,  lavender  and 
purple  are  borne  on  erect  spikes  during  the  er.rly  spring.  Some  of  the 
newer  creations,  named  varieties  having  verj''  rouble  flowers  of  clear 
colors,  are  very   charming,  and  should  find  places  in  ever;'"  garden. 

Lobelia.  Lobelias,  in  their  beautiful  shades  of  blue,  may  be  had 
in  the  d'^arf,  conr  .ct  form,  which  is  so  c.esirable  as  an  edging  and  also 
in  the  trailing  or  hanging  form  which  i?  used  in  rock  gardens,  pots, 
boxes  and  baskets.  The  ch-arming  dwa.rf  plants,  under  six  inches  in 
height,  with  many  tiny  branches,  sre  covered  with  tiny  blue  flowers 
throughout  the  blooming  season. 

Lupine.  As  subjects  for  a  tall  border  the  annual  lupines  are  very 
effective,  and  they  are  no  less  striking  as  cut  flowers.  Their  keeping 
q-uality  is  excellent. 

Moroccan  Toad  Flax.  Of  comparatively  recent  introduction  into 
Florida  gardens,  this  little  toad  flax  from  Morocco  is  rapidly  gainirg 
the  popularitj'  it  so  rightfully  deserves.   It  is  a  dwarf  grower  of 
exceeding  hardiness  that  bears  its  spikes  of  tiny,  snapdragon-like 
flowers  throughout  the  '"inter  and  early  spring. 

Pansy.  Nothing  can  approach  pansies  for  edging  or  for  bedding  in 
the  late  winter  and  early  spring.  The  newer,  highly  developed  strains 
are  characterized  by  gigantic  flowers  of  most  striking  brilliance  and 
endless  variety  of  design.  The  pansy  is  distinctly  a  cool  weather  plant; 
seeds  will  not  germinate  well  in  the  warmth  of  late  summer,  the  young 
plants  that  are  produced  are  sicklj'-  and  slow  growing. 

Petunia.  No  garden  would  be  conplete  without  petunias.  The  humble, 
sn-iall  single  sorts  are  valuable  for  color  effects,  while  the  more  pre- 
tentious, single  and  double  fringed  and  veined  g^^-'t^ts  a' ways  attract  a 
great  deal  of  attention  because  of  their  -onus-oal  text-ore,  size  and 


1+  - 


colors. 


The  small  single  varieties  are  very  easily  groTm  from  seed,  tut 
the  double  flowered  va,rieties  are  best  secured  from  florists. 

Phlox.  The  annual  phlox  is  one  of  the  easiest  of  all  plants  to 
gro^  from  seed.  A  Hi(?-3  variety  of  color  is  offered  by  the  trusses  of 
charming  little  flo-^7er3  that  cover  the  dwarf,  spreading  plants  through- 
out the  early  spring.  It  is  excellent  as  an  edging,  for  ribbon  beds, 
as  a  ground  cover  for  a  siinny  expanse,  and  for  naturalizing. 

Pinlzs,  PirJcs  are  very  ^nuch  at  home  v/ith  us;  numsrous  kinds  thriv- 
ing as  annuals  can  be  used  as  perennials  if  they  are  cut  back  in  the 
early  s'ommer  and  fertilized  for  a  second  period  of  bloom.  Ho  R,ttempt 
nil!  be  raa.de  to  distinguish  the  species  or  hybrids,  but  it  is  suggested 
that  different  kinds  be  tried  so  that  the  gardener  can  select  those 
which  are  best  suited  to  his  conditions. 

Poppy.  The  poppies  have  long  been  garden  favorites.  The  bold, 
bright  colors  of  the  hybrids  of  the  opium  poppy  and  the  fragile,  fine- 
textured,  delicately  tinted  flor/ers  of  the  Shirley  group,  offer  us  va- 
riety in  substance,  color  and  design.  Poppies  do  not  transplant  well, 
the  seeds  do  not  sprout  in  hot  weather;  hence  it  is  best  to  sow  the 
seeds  in  Hoveraber  where  the  slants  are  to  grov;. 

Scarlet  Flax.  This  red-flo-rered  aamual  variety  of  flax  that  is 
gradually  gaining  popularity  as  a  garden  subject  in  Florida  deserves 
every  gardener's  consideration.  A  hardy,  bushy  annual,  to  two  feet, 
of  exceedingly  graceful  habit,  it  is  covered  with  charming  red  open 
flowers  throughout  the  spring. 

Snapdragon.  Although  this  is  really  a  perennial,  in  Florida  it  is 

treated  as  an  annual  because  it  rarely  survives  the  high  teniperatures 

and  heavj'-  rains  of  oijj  surajr.ers.  Like  the  pansy ^=',ii«K^'the  lari'^pur,  it  is 

distinctly  a  cool  -eather  plant  and  is  really  successful  only  when  it 

is  grown  tlirough  the  vdnter  and  early  spring  months. 

Statice.  The  annual  kinds  of  statice  are  well  adapted  to  our  gar- 
dens, thriving,  if  necessarj;-,  under  difficulties.  Statice  sinuata  has, 
in  the  spring,  tall  spikes  of  blue  or  white  flowers  arising  from  dwarf, 
tight  rosettes  of  lobed,  spatuLate  leaves.  The  bonduelli  variety  is 
verj''  similar  in  habit  but  produces  yellow  flowers,  while  suworori,  tb; 
rat-tail  statice,  bears  tail  graceful  spikes  of  delicate  pinl:  flowers. 
This  last  named  species  deserves  wider  trial  as  it  is  especially  good 
and  receives  favorable  cominent  ■•'herever  seen. 

Stock.  Stoclcs  arc  old  favorites  that  have  developed  wonderfully 
at  the  hands  of  plant  breeders.  Full,  double  varieties  in  ma.ny  colors 
belonging  to  different  strains,  the  plants  of  which  vary  in  habit  and 
ti:r.e  of  bloora,  are  offered  by  the  s^cd  hor^-ses. 

Sweet  Pea.  These  are  -.Ithout  doubt  among  the  most  important  of 
our  winter  and  spring  bloomin';  annuals.  Their  fragrance,  dclicacj'-  of 
texture  and  design  have  won  for  them  a  place  in  every  heart,  but  at 
the  same  time  it  must  be  conceded  that  the  hoot  of  pests  that  prey 


-  5  - 

upon  them  is  most  alarming  ^^Jid  often  most  difficult  to  control. 

The  Spencer  sweet  peas,  non  the  nost  populp.r  group,  hftve  rep.chod 
e.   rempirkftble  state  of  perfection.  Winter  flowering,  or  "oftrly"  strains 
plnnted  in  the  early  fnll  should  start  blooming  in  Doceaiber  if  condi- 
tions are  favorable,  and  the  spring  or  "late"  flovzoring  strains,  if 
planted  in  tho  -TTinter,  should  produce  a  uealth  of  bloom  in  March, 
April  or  liry.  The  list  of  varieties  is  long  —  no  kinds  can  be  recom- 
mended as  being  preferable  to  others;  one  most  trj'  different  sorts  in 
order  to  discover  which  are  best  for  the  desired  purpoBo,  or  be  content 
T7ith  the  "mixed  paclcete." 

Plant  the  seeds  in  a  staggered  dotiblo  roTv  so  the.t  the  trollia  may 
be  orocted  between  the  rows.  TThen  the  seedlings  emerge  treat  the  bed 
with  a  soil  sterilizing  compound  to  control  damping  off.  It  is  beet 
to  thin  the  pls'.nts  to  stand  a  foot  apart.  When  the  plwits  are  six 
inches  liigh  apply  steamed  bone  meal  so  as  to  make  the  grou»d  'vhita, 
then  stir  it  in  lightly.  A  mulch  of  oal:  leavee  or  peat  moss  is  valu- 
able in  conserving;  tl-.o  moisture,  Wnen  tendrils  appear  some  sort  of 
support  must  be  provided.  This  may  bo  poultry  netting  stretched  be- 
tween, posts,  a  trellis  of  cotton  cords  running  verticjxlly  over  horizon- 
tal bars  at  top  and  bottom,  or  a  line  of  brush  stuck  firmly  into  the 
©round  between  the  rows. 

The  Tines  '/ill  stand  considerable  cold  but  the  flower  buds  are  so 
.  easily  injured  thrt  protection  on  cold  nights  is  suggested  after  the 
plpjits  have  Oooaraenced  to  bloom.

PIAUTS   THAT  PLAITT  THEIiSSLVES 

By:   John  V.  Watkins,  Assistant  Horticulturist, 

Universit;;-  of  Florida  College  of  Agriculture 


ITature  has  endov/ed  certain  plants  '7ith  the  ability  to  reproduce  and 
establish  themselves  so  easily  and  so  retpidly  that  one  often  marvels  at 
the  magnificent  displays  of  periv7in.kle,  phlox,  coreopsis,  gaillardia  and 
petunias  that  have  escaped  from  cultivation,  re-seeded,  voluiiteered, 
and  blossomed  in  profusion  v7ithout  the  aid  of  man.   In  Florida  we  find 
nujabers  of  exotic  plants  so  thorouglily  at  home  that  they  successfully 
exclude  their  neighbors  from  their  colonies. 

Of  the  annual  garden  plants  that  plant  themselves  one  of  the  most 
satisfactory  is  Sweet  Alyssum.  This  plant  in  its  several  varieties,  with 
white  or  lilac  flowers,  is  one  of  the  best  winter  blooming  annuals  for 
edging  or  for  the  rock  garden.  Portuaiately  this  dwarf,  compact  plant 
produces  myriads  of  viable  seeds  that  will  furnish  an  abundance  of  volun- 
teer seedlings  for  each  season's  planting.  These  tiny,  self-planted  in- 
dividuals irny  be  lifted  and  transplanted  as  they  appear  in  August. 

One  is  continually  impressed  with  the  self-planted  Blanket  Flowers, 
or  G-aillardias,  tliat  are  encountered  on  the  high,  dry  sand  dunes  of  our 
East  Coast.  Year  after  year  the  gay  sprightly  flowers  are  produced  from 
the  seed  of  volunteer  plants  that  are  being  scattered  farther  and  farther 
from  their  original  garden  sites.  Usually  there  are  abundant  tiny  Gail- 
lardia seedlings  appearing  in  the  garden  in  October  or  llovenber. 

That  striking  daisy-like  flower,  the  Blue-Eyed  African  Daisy,  is 
one  of  the  most  accomodating  of  the  plants  that  plant  themselves.   If 
one  has  ever  gro^mi  this  flower  and  has  allowed  the  seeds  to  ripen  and 
drop  from  the  plant,  he  will  certainly  have  enough  plantlets  in  the  au- 
tvimn  to  supply  not  only  his  gardening  needs  but  those  of  all  his  neigh- 
bors as  well.  Of  easiest  culture,  admirable  as  a  cut  flower,  the  Blue- 
Eyed  African  Daisy  should  have  a  place  in  every  self-planting  garden. 

The  California  poppy  furnishes  an  abundance  of  warm  tones  of  yellow, 
orange  and  flame  color  throughout  the  early  spring  and  very  fortunately 
for  those  lazy  but  sensible  gardeners  who  depend  in  some  measure  upon 
volunteer  seedlings,  it  also  produces  literally  hundreds  of  plants  each 
winter.   These  aa:y  be  thinned  to  stand  a  foot  apart  or  they  may  be 
transplanted  if  care  is  taken  to  move  the  long  taproot  intact  in  a  ball 
of  soil. 

The  Calliopsis,  or  Coreopsis,  is  one  type  of  the  several  daisjr-like 
flowers  that  play  so  important  a  part  in  a  garden  th^t  plants  itself. 
Of  easy  cxiltxire,  growing  in  difficult  places,  said   often  naturalizing  in 
large  colonies,  the  calliopsis  can  be  most  highljr  recommended. 


-  2  - 


For  blue  flowers  in  ths  garden  tliat  plants  itself,  one  should  cer- 
tainly consider  the  Chinese  for-get-me-not,  or  Cynoglossura.  The  volun- 
teer seedlings  th^.t  are  usually  foijnd  in  fair  numbers  bloom  in  a  very 
short  time.  Possiblj;-  its  greatest  use  is  for  blue  color  masses  in  the 
garden,  because  the  flower  spikes  u.sually  wilt  badly  when  they  are  used 
as  cut  flowers. 

The  old-fashioned  Corn  Flower  will  sometimes,  especially  in  disease- 
free  soil,  furnish  enougli  volunteer  seedlings  to  be  considered  a  subject 
for  the  self-planted  garden.  However,  it  is  not  nearly  so  dependable  as 
are  most  of  the  other  plants  we  have  mentioned. 

Probably  every  one  who  is  garden-conscious  has  remarked  at  one  time 
or  another  about  a  gorgeous  display  of  spriglitly  yellow  that  is  furnished 
by  e.   chance  patch  of  late  or  Klondyke  Cosmos.  A  rather  between-season 
annual,  the  late  cosmos  comes  into  bloom  in  October  or  Hovember  when 
blossoms  are  sorely  needed.  This  tall,  coarse,  composite  is  apparently 
not  at  all  particular  as  to  its  requirements,  as  it  succeeds  without 
care  and  escapes  from  cultivation  at  the  slightest  provocation. 

AgeratuTii,  sometimes  called  Floss  Flower,  is  a,  perennial  in  frost- 
free  areas,  but  is  a  tender,  heat-tolerant  amroal  in  those  localities 
that  experience  sub-freezing  temperatujes .  In  any  event,  it  re-seeds 
readily  and  deserves  a  place  in  our  volunteering  garden. 

G-lobe  Amaranth,  also  Icnown  as  Bachelor's  Button,  thrives  during 
hot  weather,  volimteers  profusely,  and  can  be  depended  upon  to  succeed 
\mder  almost  all  conditions  during  the  sijinmer. 

Annua.1  Larkspur  is  one  of  the  most  striking,  yet  dependable  garden 
flowers  for  the  spring.  It  is  distinctly  a  cool  weather  plant,  the 
seeds  of  which  v/ill  not  germinate  during  hot  weather.   If  larkspur  has 
been  allowed  to  mature  its  seeds,  an  abunda:"ice  of  tiny  seedlings  will 
be  found  at  this  tine  of  the  yea.r.  These  transplant  with  the  utmost 
ease.  The  flowers  borne  hy   volunteers  will  probably  be  single. 

In  late  September,  througli  October,  when  there  is  a  paucity  of  flow- 
ers, the  Marigolds  contribute  their  bright  yellow  and  orange  blossoms  to 
our  gardens  whose  brightness  has  begun  to  wane.   Certain  tj.'pes  of  mp.ri- 
golds  will  pl-'^.nt  themselves  year  after  year. 

Moroccan  Toad  Flax,  althougii  of  comparatively  recent  introduction 
into  Florida  gardens,  is  rapidly  gaining  the  popiilarity  it  so  riglitfully 
deserves.   It  is  a  dwarf  grower  of  exceeding  hardiness  that  bears  its 
spikes  of  tiny  snapdragon-like  flowers  in  the  winter  and  early  spring. 
This  Linaria  self-sows  and  volunteers  most  readily,  apparently  not  de- 
teriorating as  regards  the  quality  or  the  color  of  the  flower  even 
though  chance  seedlings  are  used  as  the  planting  stock  j'-ear  after  year. 

ITo  spring  garden  is  complete  without  Petunias.   The  giant  ruffled 
sorts  do  not  set  seeds  readily,  but  the  small  flowered,  single  variet.es 
that  you  h,ad  in  your  garden  this  year  have  lavishly  sown  their  seeds 
for  your  convenience  and  when  you  arrange  your  garden  at  this  time  of 
the  year  there  should  be  ariTple  pla.nting  stocl":  for  you  and  your  friends.

The  Periwinlrle  is  a  perennial  in  the  lo?7er  penins-ola,  where  great 
"beds  of  this  charining  plp.nt  are  forever  causing  coninent  among  garden- 
rdnded  people.  'Where  frostc  are  the  rule  the  plants  nip,y  be  killed  hut 
it  is  certain  that  there  are  enoiogh  seeds  in  the  groimd  to  perpetuate 
the  colonj?-.  Exceedingly  cosmopolitan,  demanding  nothing  from  man,  this 
Periwinlrle  froin  Ifedagascar  is  truly  at  home  in  Florida  and  should  he 
grown  in  everyone's  garden. 

The  annual  Phlox  is  one  of  the  easiest  of  all  plants  to  grow  from 
seed.  Self-sov/n  seedlings  are  miraerous  in  the  vicinity  of  old  plantings 
and  even  in  places  where  discarded  plants  have  heen  piled.  Phlox  is 
relatively  free  fror.  pests,  transplants  most  easily  and  succeeds  in 
dry,  light,  sandy  soil.  It  is  excellent  as  a  ground  cover  for  a  large 
sunny  eicpanse.  In  parts  of  Florida  it  covers  large  areas,  hlooning  in 
its  season. 

Poppies  have  long  heen  garden  favorites,  and  certainly  they  can 
never  lose  the  miiversal  popiolarity  they  have  always  enjoyed.   The  !iy- 
hrids  of  the  opium  poppy  are  plants  that  plant  themselves  par  excellence 
as  they  self-sow  ahundantly  and  do  not  transplant  readily.  Often  the 
same  garden  spot  is  occupied  year  after  year  hy  these  bold  brigjht  giants 
of  the  spring  show. 

The  Moss  Verbena  is  possibly  a  perennial  strictly  speal:ing,  but 
should  the  garden  experience  very  low  teiirpsratures  the  roots  would  be 
killed  out  in  all  probability.  Self-so7/n  seeds  will,  no  doubt,  be  pre- 
sent in  sufficient  nun;bers  to  assure  the  continuance  of  the  culture. 
The  lavender  or  occasional  white  blossoms  of  this  dainty  verbena  that 
are  borne  in  the  greatest  profusion  througliout  the  summer,  are  p.  vital 
part  of  the  garden  that  plants  itself. 

Zinnias  are  probably  the  most  i.niiortpjit  of  our  heat-tolerant  sum- 
mer annuals,  without  which  our  gardens  weald  be  colorless  indeed  from 
July  to  ITovember.  As  early  plantings  become  old,  chance  seedlings  may 
be  found  under  the  parent  plants  and  these  r;iaw  be  transplanted  to  new 
locations  for  late  summer  and  early  autumn  blooms.  However,  the  seeds 
cannot  be  depended  upon,  ordinarily,  to  carry  over  the  winter  and  fur- 
nish seedlings  for  the  spring. 

Probably  the  tallest  of  the  annuals  that  plant  themselves  is  the 
sunflower.   Certain  small  flowered  varieties  that  are  excellent  for 
cutting  during  the  summer  persist  year  after  year,  successfully  main- 
taining their  colonies.  These  volunteering  sunflowers  are  particularly 
noticeable  on  the  sand  dunes  of  our  east  coast,  grov.lng  side  by  side 
with  the  blanlcet  flowers. 

We  have  discussed  only  anntual  flowering  plants,  as  these  are  best 
adapted  to  a  garden  that  plants  itself.  When   one  has  grown  any  of  these 
persistent,  hardy  varieties  and  wishes  them  to  plant  themselves,  he  nrast^ 
of  course,  allow  the  old  plants  to  remain  long  enough  to  r.vature  their 
seeds  and  drop  them  to  tlie  ground.  Then  they  can  be  removed  to  mpke 
room  for  a  new  planting.   In  preparing  the  sord,  spading  should  be  sha?.- 
low  so  th^t  the  self-sown  seeds  are  not  covered  too  deeply.  Even  thoiij^ 


k  - 


tlie  gp.rden  beds  iray  be  in  const-ijit  use,  volunteer  seedlings  of  most  of 
the  plants  '.7e  lip.ve  mentioned  vrill  apper".!-  in  con-^iderable  numbers  nt 
their  proper  seasons,  if  cultivation  is  not  practiced  too  continually. 
If  sand  paths  are  a  part  of  the  garden  scheme,  it  'Till  be  found  tKat 
myriads  of  tinj-  volunteers  will  spring  up  along  the  edges  of  the  paths. 
Close  oboervption  on  the  part  of  the  gardener  is  necessary  so  that  the 
seedlings  na.y  be  discovered  and  transplanted  about  the  time  they  have 
developed  two  pairs  of  true  leaves.  Probably  the  most  difficult  feature 
is  the  ability  to  identify  the  plantlets  at  tre.nsplanting  time.  One 
must  learn,  by  experience,  to  distinguish  the  varieties  so  that  they  may 
be  used  in  the  garden  spots  best  siiited  to  their  lia.bit  of  gro'vth,  size, 
color  and  so  on. 

In  addition  to  the  garden  use  of  these  plants  thpt  plant  themselves 
some  are  admirably  adapted  for  roadside  use.  Some  'Till  persist  year 
after  year  in  spite  of  mowing  and  gi^azing  of  the  ropd  shoulders.  For 
roadside  use  the  lowest  growing  sorts  are  more  desirable,  and  one  of  the 
best  is  the  blarJret  flov/er  or  gaillardia.  This  plant  is  not  liked  by 
cattle,  and  is  very  persistent  in  its  growth. 

■ 

As  a  roadside  plant,  annual  phlox  he.z   already  been  used  by  several 
garden  clubs  in  the  state  and  has  proven  fine.  It  is  a  hardy  grower 
and  spreads  rapidly  if  not  pulled  up  by  admiring  passers-by.  Eight 
here,  let's  put  in  a  caution  against  this  destruction  of  roadside 
beauty.  A  tourist  vrill  say,  "My  pulling  a  few  of  those  flowers  will 
not  hurt,"  but  what  if  every  one  who  passes  that  way  says  the  same?  The 
big  trouble  is  that  r:p.ny  pull  the  plants  out  by  the  roots  instead  of 
picking  them.  These  plants  that  plant  themselves  have  to  produce  seed 
or  there  will  be  no  flo'-ers  the  next  year.  So  iTia.y  we  all  stop  aiid  thiiik 
before  we  become  a  party  to  destroying  roadside  beauty  that  is  ours  only 
to  look  at  and  enjoy  in  passing. 

Another  good  roac.sif.e  plant  that  plants  itself  is  the  Periwinlcle. 
It  will  do  well  if  not  mowed  too  frequently.   Calliopsis  is  another 
that  is  good,  although  it  attains  a  height  of  18  to  20  inches.  Though 
seldom  used,  moss  -^.-erbena  will  make  any  roadside  a  place  of  beauty.  It 
has  proven  its  value  in  several  places  in  the  state  on  railroad  right- 
of-ways  where  it  has  established  itself  in  magnificent  colonies. 

In  conclusion,  let  us  all  pay  more  attention  to  letting  these 
plants  have  a  chp/nce  on  our  roadsides  and  in  our  flower  gardens.

The  aesthetic  beauty  of  a  city,  town,  or  coirmunity  is  dependent  largely  upon 
the  appearance  of  the  home  grounds.   It  matters  not  how  well  kept  the  pa.rl:s  and 
streets,  if  the  residential  grounds  are  not  attractive  the  beautiful  effects  can 
not  result.  The  plantings  about  the  home  grounds  are,  therefore,  important.  They 
are  an  integral  part  of  the  general  landscape  and  should  be  raade  with  much  careful 
thought  and  planning. 

The  plant  material  should  be  selected  that  will  grow  properly  and  give  the 
ddsired  effect  for  a  well  planned  and  executed  planting  v.'ill  be  a  great  disappoint- 
ment if  plants  are  used  that  are  not  adapted  to  the  locations.  Some  have 
experienced  poor  results  in  plant  growth  ''oy   using  material  that  was  observed 
growing  satisfactorily  in  other  states,  but  the  mere  fact  that  plants  succeed  in 
ether  sections  is  no  criterion  that  they  will  thrive  under  different  environmental 
conditions. 

Florida  is  wonderfully  blessed  with  an  abundance  of  native  plant  material 
that  will  fulfill  the  requirements  in  a  great  maiiy  instances  in  planting  the  home 
grounds.   Then  again,  there  are  m.any  introduced  species  that  will  give  good 
results  when  suitably  located  according  to  the  demands  of  the  particular  plants 
being  used.  Here  it  should  be  borne  in  mind  that  most  hardy  shrubs  and  nlants 
ave  generally  best  transplanted  d^uring  the  dormant  season  from  about  November  15 
to  March  15 . 

The  transplanting  of  native  shrubs  direct  from  the  wilds  is  generally  more 
hazardous  than  trajisplanting  plants  from  the  nursery  where  they  have  been  grown 
for  a  year  or  more.  Native  plants,  however,  can  be  successfully  moved  to  the 
home  grounds  and  other  desired  locations  when  proper  precautions  are  taken  and 
the  material  is  suitably  situated.  The  new  locations  should  simulate  as  nearly 
as  possible  the  conditions  where  the  plants  are  grooving  naturally. 

Plants  grown  wild  seldom  have  the  heavily  branched  root-system  usually  found 
on  those  produced  in  the  nursery,  and  this  is  one  of  the  principal  reasons  why 
they  present  a  special  problem  in  transplanting.   Shrubs  that  are  to  be  moved  into 
the  gardens  should  be  pruned  back  severely  and  kept  well  watered  at  all  times  if 
the  best  results  are  to  be  had.   If  the  needs  can  be  anticipated  for  some  months 
in  advance,  it  would  be  advisable  to  transfer  the  native  plants  to  a  bed  or  row 
the  previous  planting  season  where  they  can  be  carefully  looked  after,  watered 
and  fertilized  so  that  they  will  produce  good  root-systems  before  they  are 
transplanted  to  permanent  places.

Some  fertilizer  should  be  applied  at  the  time  of  transplanting.   Steamed 
bone  meal  and  cottonseed  mea.l  are  excellent  materials  to  work  into  the  soil 
around  the  roots  as  the  plants  are  being  set.  Organic  material  is  of  much 
iraportance  to  all  garden  soils  and  it  can  be  supplied  in  composted  manures,  peat, 
and  muck.  Leaves  in  large  quantities  are  supplied  by  oaks  and  should  never  be  rakdd 
away  from  where  they  collect  in  among  the  shrubs  as  they  are  valuable  sources  of 
organic  material  and  provide  an  excellent  mulch  in  addition  to  their  fertilising 
value . 

When  shrubs  are  received  from  the  nursery  if  they  cannot  be  planted  at  once, 
they  should  be  removed  from  the  packages  and  "heeled  in"  to  keep  them  in  good 
condition  until  ready  for  planting.  The  location  for  any  group  of  plants  should 
be  such  that  adequate  growth  and  m:aximum  vigor  can  be  maintained,  and  the  soil 
should  have  the  proper  drainage  and  exposure  required  by  such  plants.   Those  that 
will  not  tolerate  shade  should  be  used  only  in  sunny  locations,  while  t?iOSe  with  a 
high  shade  tolerance  can  be  planted  vdiere  there  is  relatively  little  sun. 

The  soil  should  be  well  prepared  before  setting  the  plants.  Organic  material 
and  fertilizers  should  be  added  to  have  a  suitable  condition  for  adequate  growth. 
Everything  shoiild  be  done  with  the  idea  of  plea.sing  the  plant.   Since  azaleas, 
for  example,  cannot  be  grown  successfully  in  a  dry  soil,  during  periods  of  dry 
weather  they  should  be  frequently  '."/atered. 

The  supply  of  soil  moisture  is  of  extreme  importance,  'Without  moisture  the 
proper  functioning  of  the  plants  cannot  proceed  as  it  is  through  the  mediijim  of 
m.oisture  that  the  plant  foods  are  taken  from  the  soil.   Iloisture,  as  sap,  conveys 
the  plant  foods  to  the  leaves  and  the  available  foods  from  the  leaves  to  various 
parts  of  the  plant  for  the  production  of  growth.  Catering  the  soil  should  not  be 
postponed  until  there  is  a  wilting  of  the  leaves;  on  the  other  hand  adequate 
moisture  should  be  present  at  all  times.  A  copious  supply  of  water  should  be  made 
rather  than  the  applications  of  scanty  amoionts  that  just  ;vet  the  surface.   The 
soil  should  cGDntain  the  right  amount  of  moisture  throiighout  that  portion  occupied 
by  the  roots  of  the  plants.  For  those  plants  that  require  a  moist  atmosphere,  much 
sprinkling  must  be  done  diiring  dry  weather,  and  where  there  are  trees  that  remove 
large  quantities  of  water  from  the  top  IS  inches  of  soil  it  is  necessary  to  apply 
water  at  more  frequent  intervals  than  where  such  trees  are  not  adjacent  to  the 
plantings. 

A  permanent  sprinkling  system  installed  among  the  shrubs  will  make  watering 
an  easy  task  if  the  cut-off  valve  is  properly  located  and  the  nozzles  are  so 
spaced  that  there  will  be  a  slight  overlapping  of  the  spray  during  the  times  when 
there  is  the  lowest  water  pressure.  The  ordinary  garden  hose,  hovvever,  is 
c omraonly  msed  and  will  maintain  a  satisfactory  moisture  condition  if  it  is  con- 
btantly  looked  after.  To  give  best  results  it  should  have  attached  a  good  simple-- 
'..'orking  sprinkler. 

We  come  now  to  another  one  of  the  i.nportant  problems  in  connection  with  the 
handling  of  garden  plants,  that  of  supplying  the  necessary  plant  foods.   If  the 
soil  was  properly  prepared  at  the  time  of  setting  the  plants,  it  will  contain 
sufficient  nutrients  to  start  and  maintain  the  growth  for  some  months,  but  by 
June  or  July  additional  materials  should  be  aptjlied. 


-3- 


In  addition  to  the  importance  of  organic  matter  as  previously  mentioned, 
some  commercial  fertilizer  shoxild  be  applied  to  the  soil  in  which  the  plants  are 
growing.  This  can  be  in  the  form  of  a  complete  fertilizer  such  as  5~7-5  or  the 
materials  can  be  applied  separately.  The  average  home  gardener  will  find  the 
complete  mixture  more  satisfactory.  Bone  meal  and  cottonseed  meal,  however,  are 
find  additional  fertilizers  for  most  garden  plants. 

l^Tewly  planted  shi-ubs  should  have  been  fertilized  when  tliey  were  set,  hence 
it  will  not  be  necessary  to  give  them  a  spring  application,  but  for  established 
plant  beds,  a  complete  fertilizer  sliould  be  applied  in  the  scoring.  This  should 
be  applied  evenly  over  the  surface  of  the  soil  and  ral:ed  in  at  the  rate  of  about 
5  pounds  to  each  100  square  feet.  A  second  application  possibly  containing  more 
nitrogen  should  be  made  in  July.  No  fixed  rule  can  be  made  that  is  applicable 
under  all  conditions  as  the  composition  and  amounts  to  apply  will  vary  somewhat 
vdth  different  soil  types  and  conditions.   The  experienced  gardener,  however, 
does  not  go  so  mrach  on  measured  amo^juits  but  imows  vrhen  the  plants  need  feeding 
and  applies  fertilizers  accordingly.   It  is  important  to  remember  that  nitrogen 
is  the  most  important  in  producing  growth,  and  is  also  the  element  that  is  most 
readily  lost  by  leaching  from  the  soil.   It  should,  therefore,  be  supplied  in 
rather  liberal  amiounts. 

The  art  and  practice  of  pruning  is  as  iirportant  as  the  planting  itself. 
Tfc  matters  not  how  perfect  the  plans  nor  hov;  carefully  the  plant  m.aterial  is 
s-ilected  and  arranged,  if  the  growth  is  not  kept  within  the  size  that  it  is 
£-apposed  to  be,  the  main  effect  may  be  lost  and  the  plants  become  leggy  and 
straggly.   Instead  of  being  ob,iects  of  beauty,  they  will  present  an  unl:ept  and 
unattractive  appearance. 

Most  shrubs  will  require  a  certain  amount  of  judicious  pruning  to  I'eep  them 
from  out-growing  the  bounds  within  which  their  tops  and  branches  are  supposed  to 
la'^iain.  A  plant  may  be  of  a  dwarfed  habit  of  growth  and  fulfill  the  requirements 
of  such  a  type  admirably  when  young,  but  may  become  -onsightly  in  several  years  if 
allov/ed  to  develop  along  lines  of  least  resistance.   In  groups,  certain  plants 
will  often  outgrow  others  and  crowd  them  out  of  the  picture  to  such  an  extent 
that  they  become  out  of  shape  and  fail  to  produce  the  effect  for  which  they  were 
planted.   When  plants  get  into  such  a  condition  thrcogh  lack  of  attention,  it  is 
too  late  to  maintain  their  original  beauty  without  interruption  and,  while  it  is 
often  possible  to  cut  them  back  in  such  a  way  as  to  revive  them  and  in  a  measure 
bring  about  the  desired  appearance,  it  is  much  better  to  direct  growth  of  the 
individual  plants  by  a  proper  and  systematic  pruning  from  the  start. 

Foundation  plantings  should  be  v.-atched  and  not  permitted  to  grow  out  of 
shape,  as  shoots  can  be  cut  out  when  the  growth  is  ii-properly  located  without  harm 
to  the  plant  So   This  will  prevent  the  group  from  developing  into  one  too  large  or 
o.ie  that  is  one-sided. 

The  pruning  of  plants  in  general  used  mostly  for  a  rjxss   of  foliage,  such 
as,  banlrings,  foundations  and  screenings,  should  be  done  during  the  late  winter 
months  just  before  the  initial  bud  growth.  This  permits  the  new  top  to  shape 
itself  and  keep  its  desired  type  and  form  with  a  miniraun  of  care  throughout  the 
growing  season.  The  flowering  plaiats  will  have  to  be  pruned  at  a  time  that  will 


-U- 


not  interfere  with  flo"'er  production.  A  general  and  safe  rule  to  follow  is  to 
learn  the  flowering  habits  of  the  shrubs.  Prune  in  the  winter  only  those  that 
bloon  on  v/ood  of  the  current  season's  groivth,  and  -orune  those  that  bloom  on  second 
year  wood  shortly  after  they  are  through  blooming.  Dead  v;ood  will  occasionally 
occur  in  plants  growing  in  crowded  locations.  This  should  be  carefully  removed 
as  it  develops,  and  the  cut  should  be  made  well  into  the  green  wood  area  at  the 
junction  of  the  branches  or  to  a  bud  so  that  growth  renewal  will  readily  take 
place. 

To  briefly  sumiviarize;   I'lative  shi^ubs  should  be  c\it  bac^:  rather  severely  when 
transplanted,  and  the  soils  and  locations  should  simulate  those  where  such  plants 
are  growing  naturally.  Adequate  amounts  of  organic  materials  should  be  thoroughly 
incorporated  v-ith  the  soil  a.nd  additional  applications  should  be  made  annually 
in  addition  to  the  applications  of  commercial  fertilizers. 

Generous  amounts  of  bone  meal  or  cottonseed  meal  should  be  worked  into  the 
soil,  being  placed  arourii  the  roots  and  the  soil  should  be  thoroughly  watered 
when  the  plants  are  transplanted.  All  plants  should  be  set  as  deeply  as  they 
grew  in  the  nursery,  it  being  better  to  set  them  an  inch  or  two  deeper  than  to  get 
Them  too  shallow. 

Copious  watering  of  the  soil  is  much  more  satisfactory  than  if  the  surface 
:^f  the  soil  only  is  moistened.  Plants  tha.t  require  a  moist  atm.osphere  should  be 
sprinkled  frequently  during  dry  times  in  addition  to  keeping  plenty  of  moisture  in 
the  soil. 

The  mere  fact  that  you  are  interested  in  gardening  is  siifficient  evidence 
that  you  are  vitally  concerned  about  the  beauty  of  the  home  grounds.  May  I 
re-emphasize ,  therefore,  the  im'oortance  of  handling  plants  in  a  way  that  y/ill 
pex-mit  their  proper  development,  as  nature  has  so  generously  provided  and  intended, 
CO  the  end  that  such  plants  can  contribute  their  bit  towards  the  ultimate  beauty 
of  the  landscape.

ARCHITECTURAL  FEATURES  OF  THE  FLOliYER  GARDEU 
Rudolph  Weaver,  Director,  School  of 
Architecture,  University  of  Florida,  and 
Ai'chitect  for  the  State  Board  of  Control 


To  those  of  you  who  are  following  this  series  of  garden  talks  it  re- 
quires no  argument,  I  am  sure,  to  convince  you  that  the  possession  of  a  gar- 
den enriches  your  life.   If  you  do  not  already  own  a  garden  then  I  hope  you 
are  planning  one  in  the  immediate  future.   If  you  ere,  then,  of  course  it 
will  he  necessary  to  give  .-orae  consideration  to  certain  architectural  fea- 
tures of  your  garden. 

In  this  talk  I  am  assigning  that  any  feature  of  a.  garden  which  cannot 
be  classified  as  plant  material  is,  in  some  form  or  another,  an  architectural 
feature.   Such  elements  sre  planned  pnd  devised  as  p  setting  for  the  plant 
material,  to  enhance,  if  possible,  the  beauty  of  the  trees,  vines,  shrubs  and 
flowers.  All  of  which  should  be  tied  together  into  one  harmonious  whole  pjid 
into  unity  with  the  house  or  other  edifice,  which,  with  the  grrden,  is  de- 
signed to  delight  the  senses  ^^nd  beaiitify  the  lives  of  those  whose  good  fortune 
it  is  to  behold  the  garden  or  to  wn,lk  therein. 

Our  aesthetic  sense  dcm-'inds  thnt  there  should  be  a.  bplpnce  established 
between  the  elements  of  ?  g'-^rden.   So,  therefore,  since  JTr'.ture  is  generally 
inform?'!  it  is  possible  -"nd  desirable  to  introduce  into  the  grrden  composi- 
tion some  architectural  fer^tures  which  act  p,s  p.  tj:^.,    accenting  by  their  dif- 
ferences the  charm  of  growing  things.  But  it  should  be  recognized  as  a  prin- 
ciple that  great  restr-^int  should  be  used  and  no  features  should  be  added 
th-'t  could  be  omitted.   Tliere  is  nothing  th^t  so  easily  spoils  a  garden  as  p,n 
overabundf^nce  of  architectiiral  elements.  Avoid  overcrowding.  Also  make  your 
a.rrangements  simple.  Do  not  mistake  ingeniousness  for  design. 

Another  principle  which  sho-old  be  accepted  is  that  all  garden  archi- 
tectural p.ccessories  should  be  of  such  cfera.cter  that  they  will  harmonize  with 
the  character  of  the  house.   Hiis  should  include  stylistic  chara.cteristics  — 
if  there  ire  any  —  simila.rity  of  materials,  scale  md.   color.  These  are  ele- 
ments of  unity,  and  unity  between  house  pjid  garden  should  be  highly  esteemed. 

The  first  step  in  the  procedure  of  developing  the  architectural  fea- 
tures of  a  grrden  is  to  coi-sidt.r  the  house  plan  it:.alf .  Wliere  should  the  walks 
le-ad  from  the  house  entmnces?  TTha.t  views  do  you  have  from  the  windows?  Is 
it  desirable  to  terminate  these  views  v?ithin  the  grrden  with  some  feature? 
Through  such  an  analysis  you  mpy  develop  the  logical  location  of  the  archi- 
tectural elements,  those  structural  features  about  which  the  planting  will  taice 
place.   Ideal  results  pxe,    of  course,  obtained  when  both  house  and  garden  are 


-  2  - 

planned  together  by  one  capable  mind  or  through  the  cooperption  of  several 
minds  working  in  hprraonious  collaborrtion. 

After  the  plan  hns  been  devised  th^n  the  drt-'-ils  should  receive  care- 
ful considerrtion.   In  such  p  brief  discourse  as  tiils  it  is  obviously  impos- 
sible to  tell  whrt  should  be  included  in  r   p-Tticulp.r  gnrden  so  the  most  thrt 
cm  be  done  is  to  en'umer'"te  some  of  those  rrchitecturnl  features  which  have 
been  used  in  mrny  fine  gardens  in  various  parts  of  the  world,  and  which, 
through  repeated  use,  have  indicated  their  desirability  as  garden  elements 
and  which,  furthermore,  m'-^y  be  found  in  both  simple  and  world  famous  gardens. 

"Eo  discussion  vtIII  be  n^Ae  here  as  to  the  desirability  of  formality 
or  informality  of  structural  fe-^tures;  it  is  only  necessary  to  follow  your 
persons'l  desires  -"^nd  use  restraint. 

In  enumerating  certain  architectural  features,  I  will  first  s-uggest 
the  w^Il.  Walls  should  be  of  course,  when  possible,  of  the  s^me  m'-^terial  as 
the  house  itself  —  or  of  the  same  mr'teri->l  as  the  foundation  of  the  house. 
Wr^lls  m-"y  function  in  various  capacities.  They  maj  be  used  to  create  dif- 
ferent levels,  either  grerit  or  small. 

Walls  rre,  perhaps, the  perfect  background  for  growing  things,  especial- 
ly when  consideration  is  given  to  the  color  combinrtion  between  the  wall  and 
the  plant  material  -''Jid  betv;een  the  w-'ill  and  the  bloom,  if  -'^ny.   There  is  a 
fine  old  wall  around  the  garden  of  the  Alcazar  in  Sp'^in.   It  is  covered  with 
a.  lovely  boug.'^inville.  Wliile  the  a.rrnngeraent  is  simple,  the  effect  is  regal. 
It  is  a  good  example  for  the  Southern  ga,rden  maker. 

Wa.lls  of  cement  or  plaster-covered  masonry  are  the  perfect  backgro-und 
for  the  long  sh^dow-fonns  of  swaying  stems  and  blossoms  —  sun-printed  in 
f^iry  shapes  for  the  eyes  of  those  who  can  see  —  contrasting  the  light  of 
the  sun  with  the  restful  coolness  of  the  sh-,dows  v/J  ich  it  creates.  Here  we 
have  the  completeness  of  opposites  which  are  comj"  -entary;  manifest.''tions 
of  Nature's  generous  gifts  such  as  dark  --^nd  lighL,  v.-'rm  -"^nd  cool,  and  when 
huraaji  skill  assists  we  may  arrange  to  ep.ch  individual's  satisfaction  complete 
harmonies  of  color,  as  soft  yellow  walls  to  make  a  b?^ckground  for  lavender  or 
purple  bloom,  or  pjn.y   other  harmony  to  satisfy  the  soul. 

If,  at  a  certain  place  beyond  the  wall  there  is  a  view,  then  the  wall 
may  be  pierced  and  in  the  opening  may  be  placed  an  iron  grille  or  other  orna- 
mental device,  architectural  in  character.  Such  screen-filled  opening  soft- 
ens what  may  otherwise  seem  a  severe  handling  and  also  brings  into  the  garden 
added  charm  by  permitting  glimpses  of  the  outside  world. 

Wliere  different  levels  are  possible  by  all  means  use  a  few  steps. 
There  is  something  about  r  flight  of  steps  which  adds  a  regal  touch  to  a  gar- 
den; wide  lov/  trends,  c-oggeatir^  leisure  to  the  feet  -^nd  adding  variety  to 
the  terrain. 

Where  a  v;all  is  possible  and  -appropriate,  Vi/hat  could  be  more  lovely 
than  '>  vine  covered  pergola  placed  against  it?  ?iTiether  the  pergola  be  formal 
or  informal  makes  little  difference.  Against  the  v/'^ll  it  cre.'^tes  aji  outdoor

semi-living  room  effect  'r'here  one  mr^y   enjoy  the  "best  tl.e  g-rden  h'-s  to  offer;

the  perfume  provided  in  '11  well  pl-^nted  gj^rdens. 

The   pergolr  in  iteelf  is  one  of  the  morjt  ch-^rming  '^rchitectur'^l  fertures 
of  ^.  garden.  Do  not  ra^ke  the  posts  too  slender.   If  timher  is  used  let  the 
posts  "be  suT3st.'>nti-''l.  Fnen  the  timbers  "^re  l.->rge  enough  vines  ^re  more  ^t  home 
bec'>use  they  cr^n  tv;ine  nbout  such  structur^'^l  members  more  gr^cefullj".   Of 
course  the  pergol"  should  t«^ke  its  proportions  from  the  house  rnd  v^hether  or 
not  it  connects  with  the  house  it  should  still  seem  to  be  p-Tt  of  it  —  echoing 
its  ch-'rp.cter.   If,  for  instance,  the  house  is  of  cement  plaster,  the  pergol." 
posts  mry  be  of  the  s'^me  m^teri.'^l.   The  s-^^me  kinds  of  m'^teri'-l  recurring  here 
rnd.   there  tend  to  unify  the  elements,  which  is  so  desir-'^ble.  This  simil'^.rity 
of  m-'.terii.ls  rvoids  fussiness  ^nd  gives  thrt  ever-so-v"lued  restfulness  th^t 
induces  pe-^ce  rnd  c"lm  where  one  m^^y  cniickly  retrert  rnd  rest  from  -"^n  over-hec- 
tic v'orld. 

To  the  foregoing  m-^y  be  .-^dded,  when  sp'ce  permits,  w-^ter  effects.   In 
nil  times  '^r.d  countries  mrn  hn.s  provided  reflecting  pools  -.herein  he  m--^^  see

down  <"nd  m-'^de  nn  element  in  the  effect;  where  the  mirrored  clouds  m^y  be  seen 
to  mingle  with  the  other  reflections  in  the  pool,  thereby  bringing  to  the  nr- 
ture  lover  more  r^nd  more  of  the  ple^-'sures  of  the  out-of-doors.  Those  who  h^^ve

Foundation  plantings  constitute  one  of  the  major  elements  of  land- 
scape design.  Much  la'oor,  time  and  thought  have  been  riven  to  the  proper 
treatment  of  this  phase  of  ornamental  planting  hy  eminent  landscape  archi- 
tects and  the  follov/ing  exnressed  thoughts  on  the  subject  are  in  large  part 
drawn  from  such  authorities  as  Waugh,  Johnson  and  Van  Ifelle. 

All  groupings  of  plant  materials  designed  in  particular  relation  to 
a  house  in  its  imvediate  surroundings  are  aptly  termed  foundation  or  base 
plantings.  Such  groupings  form  a  comple.nent  in  living  green  to  the  archi- 
tecture of  the  home  and  serve  to  blend  its  structural  lines  v/ith  the  general 
surroundings  landscape.  1!^.ey   are  probably  of  less  importance  on  the  larger  and 
more  extensive  estates;  their  value  and  effect  to  a  large  degree  increase  with 
the  decrease  in  size  of  the  grounds  about  the  building. 

The  use  of  plant  materials  in  home  building  has  uiade  remarkable  pro- 
gress in  recent  j'-ears,  and  home  owners  and  home  builders  more  and  more  are 
considering  a  home  as  bein.;  incomplete  vithout  an  accompanying  setting  of  fol- 
iage*  It  is  true,  of  coarse,  that  many  houses  have  no  complerentary  plantingsbut 
w'iihtheir  value  being  demonstrated  to  a  2;reater  e::tent  than  ever  before  it  is 
no  longer  considered  as  an  overly  ez-DS'-sive  adjunct  but  as  an  onoortunity  toward 
improvement  v/ith  comparatively  little  labor  and  expense. 

Fnen  prot)erly  made,  a  foundation  plantinr  serves  several  definite 
i:airposes.   It  connects  the  house  with  the  grounds  and  adjacent  plantings  so 
that  after  a  tii/ie  the  house  and  grounds  will  appear  to  have  ^ror'n  together 
into  a  permanent  unity,  each  an  integral  part  of  the  other.  Shrubs  and  vines 
tend  to  soften  and  blend  architectural  lines,  imparting  to  the  building  a 
finished  and  complete  appearance  that  is  in  harmony  vdth  its  surroundings. 
Then,  too,  there  are  in  mai-.y  instances  ob.iectionablo  feat\ires  that  can--ot  be 
avoided  in  the  back  lot  but  which  one  does  not  care  to  have  exposed  to  the  public 
view.  These  may  be  effectually  screened  by  the  prober  use  of  either  shrubs 
or  vines.  Of  course,  all  such  views  should  be  eliminated  as  far  cs  possible, 
but  in  those  instances  where  this  cannot  be  accomplished,  suitable  plantings 
will  help  materially,  and  in  addition  will  aid  in  the  improvement  of  the  general 
apcearance  of  the  whole  place. 

Around  the  high  and  open  a.nd  unsightly  foundation  that  is  in  common 
use  because  of  the  ventilation  afforded  during  the  sumr.er  months  is  indeed  one 
place  where  foundation  plantings  are  of  decided  worch,  since  they  allow  the 
wanted  ventilation  and  at  the  same  time  remove  the  stilted  arroearance  of  the 
house.  Again,  properly  placed  plantings  dress  up  a  property,  increase  its 
value,  and  transform  it  from  just  a  house  to  a  home. 

ITot  so  Ion?  ago  the  possible  effects  of  plants  on  architecture  were 


-2- 

obscured  by  house  design  itself.  There  vas   that  period  nhen  ornate  building 
frills  were  in  vogue  and  fancy  scroll  v/ork  in  wood  and  wrought  iron  were  con- 
sidered, rather  than  plants,  as  the  means  of  ornamentation. 

However,  with  the  passing  of  the  unduly  conspicuous  building  modes 
and  the  entrance  of  the  simpler  and  more  logical  architecture  there  came  also 
a  clearer  understanding  and  appreciation  of  the  close  relationship  between 
home  architecture  and  planting.   It  was  readily  seen  that  a  well  designed 
house,  -with  its  fitting  complement  of  plants,  had  resulted  in  combining 
architects'  plans  with  plantsmen's  plans  into  a  unit  that  opened  up  a  new  era 
in  the  principles  of  architectural  planting  and  led  to  that  highly  specialized 
branch  of  agriculture  nov;  so  well  known  under  the  name  of  landscape  architec- 
ture. 

Fortunately,  there  are  no  highly  specialized  or  so-callad  standar- 
dized designs  which  require  the  usage  of  certain  plantt  to  the  exclusion  of 
others  and  since  ever,  the  sano  varieties  of  plants  differ  ■'■aterially  in  size 
and  growth  habit  it  is  seldou  tl'^at  two  separate  plant  in,  :g  ar^  seen  that  bear  any 
strikin,';^  resemblance.   Thus,  each  planting  is  more  or  loss  a  distinct  entity 
and  there  is  little  liklihood  of  sameness  or  monotony  in  landsr.ping  designs. 

Any  house  reflects  the  realtion  of  nearby  plants  aiid  plantings.  Un- 
suitable plants  detract  from  its  appearance;  on  t>e  o^her  hand,  it  will  gain 
from  congenial  association.  Sarrounding  plantin^^s  ii^part  of  th^^ir  nature,  and 
no  home  is  complete  until  planted. 

Plantings  reflect  ji.r  personal  preferences  for  plant  materials,  but 
only  those  she -Id  be  us^d  whi ^h  are  compatible  with  the  outer  characteristics 
of  the  home.  Thi<!!  is  well  illustrated  in  the  different  architectural  types 
in  Florida  wherein  Colonial,  Old  3•^■?;lish  and  Spanish  modes  are  found.   Many 
of  the  gaily  colored  acalyphas,  crotons  and  other  tropical  plants  are  used  to 
advantage  in  the  tropic;-!  portions  with  the  Spanish  types,  but  the  same  plants 
could  hardly  be  co'siderod  to  be  so  W3ll  adapted  for  the  others;  and  likewise, 
the  coniferous  varieties  adapted  to  the  Colonial  or  English  types  would  not  be 
so  well  fitted  to  the  Spf  ■  _sh.  The  point  ca-.:.not  be  too  strongly  emphasized  that 
the  primary  aim  is  tov;ard  plant  effects  and  rot  the  masimum  development  of  plant 
specimens. 

Tlie  usual  and  dosiratle  scheme  of  planting  allows  for  visibility  of 
the  house  from  the  strcot  or  road.  Tliis  calls  for  open  lawns  -J.nd  imparts  the 
desired  appearance  of  spaciousness.   In  plar.-ing,  the  scheme  should  first  be 
thoroughly  vorked  out  and  clearly  visualized  with  duo  corsideration  being  given 
to  each  of  the  different  typos  of  plants  that  will  be  Ui^cd  —  their  adaptability 
to  the  soils  and  location,  their  ultimate  size,  and  compari'Civo  rates  of  grovth. 
Their  resistance  to  insect  or  disease  attack  should  not  be  overlooked.  Plants 
should  not  be  chosen  merely  because  they  have  an  apoeal  in  the  nursery  row  nor 
because  their  size  at  the  ti.ae  is  suitable.  Adaptability  and  eventual  develop- 
ment must  bo  considered.  For  those  who  are  inexperienced  in  planting  or  unac- 
quaintod  v;ith  the  many  available  plants  suitable  for  foundation  plantings, 
there  are  numerous  Florida  nurserymen  who  will  cheerfully  furnish  ideas  or 
schemes  of  planting,  together  with  lists  of  plants  best  adapted.  Many  books 
and  bulletins  are  also  available  tliat  will  supoly  the  wanted  information  as  to 
arrangement,  adaptability,  selection,  and  care  of  ornamentals  suited  to  founda- 
tion planting. 


-3- 

Ir.  the  choice  of  plants  there  are  several  factors  that  if  given  due 
consideration  before  planting  'Till  make  for  more  satisfactory  results  in  the 
later  development  of  the  planting.  Because  of  the  variation  in  cliniatic  con- 
ditions in  the  latitude  extremes  of  Florida  it  is  of  primary  importance  that 
the  plants  chosen  be  hardy  enough  to  nithstand  the  coldest  temperatures  of  the 
region  w'here  planted.  I'othing  is  quite  so  disap-ooin-cing  and  discouraging  as 
the  loss  of  a  portion  of  one's  plantings  by  freezing,  for  the  gaps  left  in  tlie 
foundation  are  later  difficult  to  fill  quickly  and  satisfactorily.  The  sea- 
sonal effect  of  flo'.Terii-'.g  varieties  must  not  be  overlooked  and  blossom  colors 
can  be  chosen  to  obtain  the  most  striking  and  harmonious  effects.  Attention 
must  be  given  to  soil  acidity;  not  all  plants  will  thrive  under  like  soil  con- 
ditions even  though  every  effort  has  been  directed  toward  giving  them  adeqiiate 
attention  in  the  way  of  coil  fertility.   The  type  of  foundatior,  whether  it 
be  high  or  low,  more  or  less  open,  or  closed  except  for  ventilatorsj  V7ill  have 
a  strong  influence  on  the  type  of  shrubbery  suited  as  well  as  on  the  arrange- 
ment of  the  plants.   G-enarally  with  open  foundations  the  effort  is  toward  an  un- 
broken bank  of  green,  while  with  the  low  concrete,  brick  or  stucco  foundation 
the  groupings  are  more  scattered  and  smaller-growing  plants  are  used.  Heavily 
shaded  locations  usually  require  an  entirely  different  treatment  from  sunn^ 
situations,  since  many  plants  a,re  not  adapted  to  both  exposure  extremes. 

In  foundation  plantings  there  should  be  free  use  of  evergreens,  not 
necessarily  conifers,  but  anythin?  other  than  a  predominance  of  deciduous 
plants.  Florida  planters  have  a  distinct  advantage  over  those  of  northern 
latitudes  in  that  the  variety  of  plants  ad.apted  to  this  use  is  extremely  wide 
and  varied.  iTearly  any  desired  effect  can  be  secured,  as  there  is  ar.  almost 
endless  variety  of  tj'-pes,  heights,  and  outlines,  as  well  as  foliage  variations 
among  them.  Usually  the  conifers  are  sDari:".gly  used,  their  placement  being 
where  accent  points  are  desired  with  the  balance  of  the  planting  consisting 
of  a  well-chosen  variety  of  broadle:  ved  evergreen  shrubs. 

In  the  arrangement  of  materials  it  is  not  practicable  to  lay  down 
any  hard  and  fast  rules  for  the  creation  of  good  foundation  plantings.   Plants 
in  pots  or  tubs  may  be  tried  at  different  places  before  they  are  finally  set. 
Eacli  situation  has  its  own  peculiarities  and  presents  a  problem  of  its  ovm. 
Conventional  planting  schemes  need  not  necessarily  be  followed.  Bold  planting 
after  a  creful  study  of  the  requirements  of  a  sitxiation  usually  brings  desir- 
able results.   Such  a  method  ass^ares  an  effect  differeiit  than  th-<t  of  one's 
neighbors  ana  gives  a  sense  of  individuality  t'l  t  should  be  reflected  in  every 
phase  of  home  building. 

As  the  informal  typii;  of  planting  is  the  more  desirable  and  most  com- 
mon, it  is  a  K\'eneral  practice  to  choose  two  or  three,  or  more,  accent  points 
on  each  side  of  the  house  to  be  planted.  Such  accent  points  might  be  corners, 
wide  spaces  between  windows  or  doors  and  on  each  side  of  entrances.  At  these 
points  the  principal  emphasis  is  -iven  by  planning  the  largest  grclng  and 
most  conspicuous  plants.   It  is  not  at  all  necessary  that  the  foundation  plant- 
ing be  continuous,  r)articula,rly  if  the  foundation  is  of  brick  or  stone.   Vines 
have  a  prominent  place  and  each,  unless  a  solid  wall  coverirg,  can  represent  a 
considerable  accent. 

A  few  "don'tg"  might  be  included  to  advantage. 

Don't   overplant.      Over-planting  is  a  common  fault  and  the   crowding 
of  too  much  miscellaneous  nnterial   into  a  foundation  planting  is  one  of   the 


conmonest  errors  ;5tf  arnateur  enthusiasm. 

Don't  depend  too  much  on  annuals  as  the  basis  of  the  planting.   They 
require  continuous  replacement  and  during  sone  seasons  of  the  year  cannot 
he   expected  to  have  much  ornamental  effect.  Perennial  evergreen  sliruhs 
should  form  the  primary  planting  -^^'ith  the  annuals  to  "be  used  as  a  supplement  if 
they  are  desired.  i 

Don't  use  too  large  or  too  conspicuous  materials.   2rees  can  he  ad- 
vantageously utilized  only  against  the  largest  of  buildings  and  some  of  our 
variegated  foliage  plants  do  not  fit  in  vrell  v;ith  all  types  of  architecture. 

Don't  use  too  mar^''  conifers.  There  is  almost  no  restriction  in 
variety  of  broadleaved  evergreens  that  are  ideally  adapted  to  foundation 
plant  ing . 

Don't  be  afraid  of  your  or.'n  ideas  as  to  plants  and  planting.  Yours 
may  give  as  good  effect  as  if  it  had  been  planted  from  a  blueprint.  This  is 
not  offered  in  disparagement  of  landscape  designs,  but  since  many  of  us  can- 
not afford  the  services  of  a  landscape  architect  V7e  should  not  let  such  a 
short-coming  dampen  our  enthusiasm. 

Lastly,  don't  fail  to  plant  some  sort  of  a  foundation  planting,  if 
it  has  not  already  been  done.  There  are  yet  too  many  houses,  both  rural  and 
urbRn,  that  are  bare  of  plantings.   Tne  ti.ae,  money  and  effort  expended  will 
be  returned  many  times  over  in  the  satisfaction  derived  from  the  enl-.anced  ap- 
pe.rv;rc,nce  and  valuation  of  your  home.

CHOICE  PLAMS  TO  USE  IN  FOU^IDATION  PLMTINGS. 
3y  -  W.L.  Floyd,  assistant  dean  and  professor  of 
horticulture,  University  of  Florida  College  of 
Agriculture. 

In  a  subtropical  climate  such  as  ours,  plants  that  grow  and  look  green  when 
those  of  more  northern  regions  appear  bare  and  lifeless  are  especially  desirable. 
The  broad  leaved  evergreens  are  fine  for  this  purpose  and  Florida  has  a  nunber 
native  to  the  state  and  many  others  that  have  been  introduced  from  foreign  climes. 
Time  does  not  permit  enumerating  the  many  fine  plants  available  for  foundation 
plantings  in  Florida,  '''e  will,  hov/ever,  discuss  a  fevi   of  the  choice  ones. 

Cherry  laurel  is  the  first  one  we'll  discuss.   It  is  a  native  shrub  or  small 
tree.   It  may  be  kept  pruned  to  shrub  size  for  a  long  time.   It  has  dark  green, 
oblong  leaves,  2  to  U  inches  long,  bears  small,  white  fragrant  flowers  in  racemes 
in  late  winter  and  spring.  The  fruit  ripens  in  late  autumn  and  resembles  a  cherry 
except  that  it  is  black.   Cherry  laurel  is  easily  propagated  from  seed,  it  may  be 
planted  in  a  garden  row  much  as  peas  or  beans,  allowed  to  grow  for  a  season  or  two 
and  then  transplanted.   It  is  valuable  as  a  hedge  plant.   It  stands  shearing  well, 
and  stools  out  at  the  base,  thus  forming  a  wall  of  green  from  the  ground  up. 
Wien  placed  where  it  has  plenty  of  room  and  pruned  from  the  bottom  it  develops 
into  a  small,  attractive  tree.   Cherry  laurel  requires  a  well-drained  soil,  it 
being  practically  worthless  on  wet,  poorly  drained  soils. 

Wsjc  privet  is  another  choice  foundation  plant.   It  com.es  to  us  from^  Japan  and 
is  one  of  the  most  popular  members  of  the  privet  fainily.  No  foundation  plant  is 
seen  more  often  about  Florida  homes.  Occasionally,  we  hear  uncomplimentary 
references  to  it  because  it  is  so  common,  but  such  are  ill  advised  as  the  plant  is 
attractive  and  worthy  of  a  place  in  the  most  carefully  developed  planting. 

It  has  broad  oval  leaves  U  to  6  inches  long.  They  are  dark  green,  shining 
as  though  waxed,  which  probably  suggested  its  common  name.  Flowers  of  white  or 
cream  are  produced  abundantly  in  spring.   The  frait  is  blue-black,  berry-like  with 
1  to  U  seeds.   These  may  be  used  for  propagating  new  plants,  but  like  most 
seedlings  of  shrubs  and  trees  do  not  come  true  to  the  parent  type.  The  plant  is, 
thus,  best  propagated  from  cuttings.  Wax  privet  stands  pruning  well,  and  grows  in 
soil  of  medium  or  low  fertility  in  sun  or  partial  shade.   It  is  attacked  by  root 
knot  to  a  limited  extent.  There  is  a  variety  tricolor  which  has  leaves  variegated 
with  yellow  and  pinl:  wh^n  young. 

Other  privets  sometimes  grown  in  Florida  are  the  Japan,  California  and  Amoor 
River.  The  two  latter,  because  they  are  hosts  of  whitefly,  should  not  be  planted 
in  citrus  growing  sections. 


-2- 


Found  so  often  along  with' wax  privet  as  to  be  generally  thotight  of  as  its 
companion  plant  is  Pittosporum,  having  no  well  known  comirion  name.   It,  too,  is  a 
native  of  Japan.  The  leaves  are  somewhat  lighter  green,  smaller,  more  leathery 
arxL  of  different  shape  from  privet,  with  which  they  form  a  pleasing  blend.  The 
branches  develop  in  whorls  of  from  3  to  6  from  the  nodes,  and  the  flo'vers  are 
creamy-white  in  fragrant  umbels  borne  in  spring.  The  fruit  is  an  inconspicious 
capsule.  There  is  a  variety  with  leaves  variegated  with  white  but  it  is  not  so 
well  suited  for  foundation  planting  as  the  green. 

The  viburnums  are  a  large  group  of  well  kno'-vn  shrubs,  among  which  are  several 
native  species  most  of  which  are  deciduous!  the  two  most  desirable  evergreen 
species  the  sweet  or  odoratissimumi  and  suspended  or  suspensurn  come  from  India  and 
Lin  Kin  Islands.   They  are  much'  alil:e ,  the  leaves  of  the  first  being  somewhat 
smaller,  the  plant  m.ore  erect,  and  the  flowers  in  small  erect  panicles,  while 
those  of  the  latter  are  drooping.  The  leaves  are  glossy,  light  green,  differing 
in  color  and  texture  enough  from  those  already  described  to  give  pleasing  variety 
when  planted  with  them.   They  are  quite  free  from  insect  pests  and  diseases, 

Abelia,  we  must  not  leave  out.   It  is  a  shrub  of  wide  range,  of  long  willowy 
growth.   Its  small  oval  leaves  often  show  pink  or  red  while  young  and  turn 
bronze  in  autumn.  The  small  tubular  flowers  of  white  tinged  with  pinlv  are  borne 
in  panicles  from  June  to  November.   It  is  a  native  of  Chiiia,  likes  full  sun,  and 
is  propagated  mainly  by  cuttings, 

Severinea  is  a  spiny  shrub  worthy  of  oxir  consideration.   It  has  oblong 
dark  green  leaves  about  1^  inches  long.'  Its  flowers  are  white,  fragrant, 
opening  in  late  winter  and  early  spring,  followed  by  a  fruit  which  is  a  sruall  beriy 
that  is  black.   Severinea  is  low  and  spreading,  thrives  in  sunny  positions,  is 
related  to  citrus  and  comes  to  us  from  the  same  region,  south  China. 

The  Jasmines  form  a  valuable  group.   Many  of  them  are  climbing  or  half 
climbing,  the  latter  m.ay  ee.sily  be  pruned  to  grow  as  dropping  shrj.bs,  a 
characteristic  which  is  cdesirable  in  some  plants  of  a  mixed  planting  such  as 
those  made  against  foundations  usually  are. 

The  graceful  and  the  downy  varieties  each  have  bright  green  leaves,  and  bear 
white  fragrant  flowers  in  dense  hanging  heads  through  a  greater  part  of  the  year. 
They  are  so  much  alike  that  they  are  often  confused,  and  because  of  the 
appearance  of  their  white,  star  shaped  flowers  so  conspicuous  amid  the  wealth  of 
small,  green  leaves  they  are  often  called  Star  Jasmine,  as  are  two  or  three 
others  of  the  Jasmine  group. 


% 


Then,  there's  the  primrose  Jasmine.   It  bears  yellow  primrose  like  flowers, 
has  dark  green  shiny,  compound  leaves  of  three  leaflets.   Its  young  stems  are 
also  green,  the  flowers  are  1  to  2  inches  across  and  flowering  continues  through 
a  long  period.   It  is  a  native  of  China,  grows  well  in  sandy  soil  under  a 
considerable  amount  of  shade. 

All  the  Jasmines  are  easily  propagated  by  cuttings  or  layers,  occasionally 
forming  natural  layers  about  old  plants  where  drooping  branches  rest  on  the 
ground .

Another  choice  foundation  plant  is  t?ie  Feijoa,  The  Peijoa  comes  from  South 
America  and  is  important  hecause  of  its  gray-green  foliage,  which  gives  an  added 
shade  in  the  coloring.   It  bears  lovely  purplish  flowers  singly  in  spring,  later 

,j  ripens  a  few  oval  edible  fruits  about  the  size  of  peaches.   They  are  green  with  a 

fi  tough  of  crimson.  The  Feijoa  is  easily  propagated  from  seed. 

A  pleasant  reminder  of  our  readings  in  classic  literature  where  heroes 
were  crowned  with  myrtle  and  laurel  is  Sweet  Ilyrtle  which  has  been  brou^t  to  us 
from  Southern  Europe  and  is  the  classic  myrtle.   Its  leaves  are  oval  about  one 
inch  long,  it  has  shining  and  aromatic  flowers  that  are  srfiall  white  or  rose 
tinted,  and  the  fruit  is  a  s:;ali  blue-black  berry.   Sweet  liyrtle  may  be  easily 
kept  to  a  height  of  3  to  U  feet,  though  left  un-^)runed  it  may  become  10  feet  high. 
It  is  of  erect  compact  habit  and  has  no  serious  pests  or  diseases.  Frost  dis- 
colors it,  but  in  spring  it  recovers  its  true  color  if  the  cold  has  not  been  too 
severe.  There  is  a  smaller  xeaved  form,  also  a  variegated  one.  These  should  be 
used  with  careful  discriir-inatioa  as  they  do  not  always  blend  well  with  broader 
leaved  plants.  Svieet   Myrtle  will  do  best  on  a  dry,  well-drained  soil. 

Another  of  the  myrtles,  wax  n^'-rtle,  is  a  native  not  given  the  attention  it 
deserves.   Its  foliage  is  almost  olive  green,  it  grows  easilj'  and  blends  well  with 
other  plants.   Its  berries  are  coated  v^/ith  wax  which  gives  the  plant  an 
interesting,  unusual  appearance.  'There  is  a  dwarf  form  which  is  also  important 
where  plants  that  grow  only  1  to  3  feet  high  are  wanted. 

All  the  time  must  not  be  used  in  talking  of  bro-ad  leaved  evergreens  even 
though  few  have  been  discussed  of  the  large  number  that  years  of  introducing, 
trying  out  and  selecting  by  plant  lovers  have  given  us. 

Pi      In  a  state  where  such  coniferous  trees  as  the  pine,  cjrpress,  and  cedar 
occupy  so  prominent  a  place  in  the  la^ndscape,  small  forms  may  well  be  used  among 
our  ornamental  plantings. 

Tall,  erect  forms  fit  into  narrow  spaces  v/ell,  and  often  at  corners  and  in 
angles  give  variety  and  pleasing  contrast  to  the  more  abundant  broad  leaved 
evergreens  among  which  they  are  placed. 

The  arborvitae  are  a  varied  and  interestinsj;  group.  Many  are  of  small 
compact  growth,  some  are  upright  columnar  tj^e,  others  like  the  Rosedale  hybrid 
and  Compacta  are  rounded  or  ovoid,  some  are  golden,  some  are  blue,  green,  and  the 
greater  number  are  bright  green.  Thus,  a  color,  size  and  shape  may  be  selected 
for  almost  any  position. 

There  are  many  other  choice  coniferous  plants,   Italian  cypress  is  a  tall, 
narrow  form  of  value,  though  very  little  used  in  Florida.  Phitzer's  juniper  is 
a  spreading  form  2  to  3  feet  high  and  5  to  6  feet  wide.  Japanese  juniper  is  an 
oval  form  growing  not  over  5  or  6  feet  high.   Creeping  juniper  spreads  along  the 
ground  reaching  a  height  of  only  6  to  12  inches,  the  Yew  or  Podacarpus  is  erect 
and  narrow,  seldom  exceeding  6  feet.   Our  native  Comptie  or  Zai.iia  looks  much  like 
a  coarse  fern  but  v;ill  grow  in  dry,  sunny  places  where  ferns  will  not  thrive. 
These  are  a  few  of  the  conifers  we  have  to  select  from  that  have  proven  their 
adaptability. 


-U- 


Still  another  group  of  plants,  ferns,  haye  a  place  against  shaded  walls, 
and  underneath  larger  plants,  v/here  plenty  of  organic  matter  and  water  can  be 
supplied,  the  Sword,  Boston,  leather  and  other  cultivated  varieties  as  well  as 
attractive  ones  from  the  Vi'oods  make  green  and  attractive  angles  and  spaces, 
where  few  other  plants  can  be  grown  successfully. 

In  hays  and  other  sms.ll  indentations  to  face  do.;n  the  higher  plants  and 
add  color  may  "be  placed  herbaceous  perennials  such  as  fotir-o- clock.  Stoke' s 
aster,  penstemon,  physostegia,  wandering  Jew,  and  violets. 

For  such  positions  a  n-uinber  of  bulbous  plants  are  useful,  as  the  day  lily, 
zephyr  lily,  oxalis,  snow  flake,  narcissus  and  others. 

IJo  state  has  a  greater  variety  of  material  for  making  an  attractive  year 
round  planting  about  the  home,  and  no  effort  will  add  more  bear.ty  and  grace 
to  the  home  grounds,  especially  when  combined  wr.'ch  an  open,  v/ell  l:ept  lawn, 
a  well  planned  border  plant ixig,  and  a  house  painted  to  3aa.rmonize  with  the 
surro'ondings.

G-vovi'^r   Roses  in  Flori'-la 

Mrs.  S.  F.  Poole 
Presidert  Florida  :^ose  Society. 


ilo  flovrer  today  is  deservedly  more  popular  -il^an  the  rose  -  tlie  queen 
of  flowers.  Everj^  lior.ie  should  have  a  rose  gp.rde-? .  I'othinr,  .^ives  to  the  home  the 
saine  atmosphere  of  disti'^ctio:'.  as  the  rose  r.'arden. 

".{any  people  "believe  roses  can-ot  "be  /?-row.-i  succjssfull^'  in  Florida,  but 
under  t)roT3er  care  ?/9  may  grov/  "beautiful  roses  successfully  in  a:^.y  section  of  the 
state.  T-ere  is  r'o  flovfer  fiat  will  .-,ive  mjre  -ratiifyi^^';  results  than  the  rose 
when  proiTerly  cul-civa.ted  ,  and  the  "ro'pin::  of  roses  is  not  s^ach  a  "big  problem. 

People  comin':  ere  from  othnr  states  to  sTie.id  their  '.7inters  are  disap- 
pointed to  see  so  few  rose  .-ardenc!. .  He  have  ".ad  wi'-tar  visitors  ask  us  if  they 
could  visit  our  rose  ,;"ardG-,  r:-:nar>i-- ':  V-rc   "  J .oy   had  rot  seen  any  roses  .'j;rowing 
in  Florida." 


Florida  is  foremost  cf  "11  statin  ir  \.r:2   u"iion  in  climatic  advai').ta-~es, 
yet  ■oerhaps  gro'"r>  fewer  roses  than  many  of  her  sinter  states.   True,  t'-cre  arc 
natural  climatic  disa-'vantPA-es  in  Flori-'.aj  such  as  our  hot  ai'.d  wet  sumiors.  On 
the  other  hand  we  have  fine  ci-ov/in:-;  conditions  from  Octo"ber  to  April.  !E;.crc  are 
some  varieties  of  ror,cr>,  like  the  Pornots,  that  will  not  stand  the  rainy  season. 
Tlio  solution  wc  offer  is  to  plant  those  varieties  each  fall,  cn^ioyin^^;  e^n  abundaneo 
of  beautiful  flo'-'ors  durin,;;  t'.c  vdntcr  and  spring-  before  the  raiay  season  start'".. 

I'ow  is  a  rood  time  to  plan  and  plan,t  a  rose  f;arden.  Rose  bushes  have 
never  been  as  cheap  as  they  ar^  today.   Give  thou.-;ht  to  the  fgroiDer  location  of 
your  rose  garden.  Choore  a  well-drained  loca.ticn  away  from  the  roots  of  trees, 
and  where  the  sun  shines  at  least  half  of  the  day.  A  moist  spot  is  desirable 
in  so  far  as  this  will  a-^'-ist  in  ms,intaininA'  the  pro-'-^er  condition  of  moisture 
without  exces'^.ive  need  for  ••'av.crin".  At  ti.e  same  time  it  is  essential  that  v/a^j.. 
does  not  stand  and  nta  :nato  in  the  ncil.  After  chocsin;':  the  location  and  arranj-i- 
in,-^  for  drainage  and  for  the  equally  imnort^-nt  ma-'.er  of  water  ou-only,  the  next 
thing  to  be  co-^sidered  is  the  ■oropar-^tion  of  the  soil.   If  j''our  soil  is  light 
and  porous  prcparo  it  to  the  doDth  of  about  ei:ihteen  inches.   In  dig;,-ing  out  the 
bed  place  the  top  soil  on  one  side  and  the  subsoil  on  the  other.  Ticn  fill  in 
•with  alternate  layers  of  top  soil  and  corapost.  T!.-is  compost  is  well  made  of  two 
Parts  of  muck  and  one  part  of  cow  manure.  Eio  compost  should  be  prepared  several 
weeks  before  usinn  to  allow  it  to  ago.  Peat  moGS,  or  djcaycd  leaf  mould,  may  be 
added  to  the  compost.   To  this  add  a  liberal  amoiint  of  bone  meal.  Mix  all  these 
materials  thoro'ghly.   If  you  wish,  clai'  may  be  added  to  this  mixture.  Clay 
gives  body  to  the  soil  and  assists  in  the  retention  of  HiOisture.   On  the  other 
hand  should  your  '~,oil  be  heavy,  dig  ouv  a  portion,  of  .he  claj'",  preferably  subsoil 
and  add  sand  and  nuriTas  so  o hat  water  '--ill  drain  through  readily.

roses  budded  on  this  stock  are  vigorous  and  make  a  good  gro'wth  the  first  year, 
Uie  fact  renains  that  bushes  on  this  stock  do  not  stand  oxir  rainy,  season  a.3  ~ell 
as  those  on  Texas  Wax. 

In  planting  the  roses  prune  the  bushes  to  about  eight  inches.  Plant 
them  from  15  to  2^  inches  apart,  depending  upon  the  variety.  This  will  place 
the  plants  close  enough  together  to  shade  the  ground  above  the  roots,  thu?-  keep>- 
ing  them  cooler  and  more  moist.  A  i'n'eat  deal  of  space  is  wasted  in  most  ..-ose 
beds  by  spacing  the  plants  too  far  r,  art.  Hybrid  perpetuals  should  have  a  dis- 
tance two  to  two  and  one-half  feet.  Wider  spaces  should  be  left  every  four  or 
five  feet  for  paths  to  permit  proper  cultivation  and  watering  and  room  for  cut- 
ting flowers.  The  bushes  should  be  set  at  the  sane  depth  as  they  were  groring  in 
the  nursery.  Firm  down  the  soil  thoroughly  aroimd  the  newly  set  plants.  Then 
water  the  plants  adequately  for  they  should  be  kept  moist  until  the  roots  have 
taken  holdc  Excess  moisture  at  this  time  prevents  root  growth.  After  plants  are 
rooted  keep  them  watered  well  during  dry  weather.  Take  time  to  set  your  rose 
bushes.   They  look  better  and  are  more  successful  if  a  number  of  the  same  kind  are 
planted  together  rather  than  scattered  miscellaneously  through  the  bed.  Then  too,, 
the  stronger  growers  are  sure  to  encroach  upon  the  weaker  sorts  and  prevent  tneir 
development . 

As  to  fertilization,  roses  are  gross  feeders  and  if  fine  quality  blooms 
with  long  stems  are  to  be  expected,  a  v.q\\   planned  fertilizing  program  must  be 
carried  out.  There  is  nothing  better  than  dairy  manure,  bone  meal  or  tankage. 
An  application  of  hard  wood  ashes  annually  may  correct  acidity  as  well  as  stimu- 
late ijacterlal  action.   This  double  function  makes  more  plant  food  available..  Xyi 
the  fall  and  again  about  the  first  of  March  it  is  well  to  use  some  complete  bal- 
anced fertilizer  V7ith  an  organic  base  containing  all  the  elements  of  plarit  food, 
such  as  nitrogen,  nhosphoric  acid,  and  potash.  The  firstof  June  give  your  rooes 
a  liberal  application  of  bone  meal  and  then  do  not  fertilize  them  again  until 
fall.  Allow  the  plants  to  go  partially  dormant  during  the  hot  and  wet  periol= 
We  rmist  always  bear  in  mind  that  all  of  the  flowers  come  on  the  new  growth  and  to 
get  this  growth  we  should  fertilize  regularly  every  month  or  six  weeks  during 
'rail,  winter  and  spring. 

Cultivation  versus  Mulchiy.f:;  much  has  been  said  on  this  subject.  Ma::^ 
rose  growers  have  better  success  mulching,  others  prefer  shallow  cultivation.  We 
l^elieve  it  depends  on  your  own  local  condition.  We  prefer  a  mulch  of  oak  leave -j, 
^rass  clippings,  peat  moss,  or  any  suitable  material  during  the  summer,   it 
shades  and  keeps  the  ground  cool  and  moist.  During  the  winter  we  practice  shal- 
low cultivation. 

Many  questions  are  asked  about  pruning.   I  have  found  it  best  to  prone 
in  September  or  October,  depending  upon  the  condition  of  rose  bushes.   In  cut- 
ting back  rose  plants  do  so  v/hen  and  where  you  have  mature  wood  and  a  strong  eye 
to  cut  to.  Of  course  the  conount  cut  back  will  depend  upon  the  strength, "-^Igor  and 
variety  of  the  plant.  Plants  should  be  gone  over  thoroughly,  cxitting  out  disease.', 
dead  and  weakened  wood.  Leave  abotit  six  of  the  best  and  strongest  canes.   In  ai:. 
pruning  a  symmetrically  shaped  bush  should  be  kept  in  mind. 

If  your  rose  plants  are  not  doing  well  perhaps  they  are  not  gettir^g  the 


:  -  3  - 

proper  care.   It  :iay   be  lack  of  foo",  soil  conditions  caasoj.  "by  C3rtain  tj'pes 
of  fertili-jer,  lack  of  i-.oi'-iture,  roots  of  ot'.ier  plants  or  tree',  or  it  raay  be 
caused  by  a  fungous  disp:ase,  sr.cli  as  b''.acl:  spot,  or  pov^dery  imldew.   If  you 
have  neglected  to  fertilise  give  f.ie..  a  liberal  application  of  a  complete  fer- 
tilizer, such  as  a  foui--ei;Sht-five  anal^-sis.  Then  give  them  a  thorough  water- 
ing.  If  the  bushes  should  still  refuse  to  grow  tr;'-  moving  them  to  a  ne'.7ly  pre- 
pared bed,  or  if  you  wish  to  leave  them  in  the  same  bed  dig  them  up  and  heel 
them  in  while  you  remove  the  old  soil.  Then  iiialie  a  new  bed  into  which  you  may 
reset  your  bushes.   Choose  the  time  when  the  plants  are  at  the  nearest  point 
of  dormancy.  They  should  be  cut  baclr,  both  tops  and  roots. 

The  most  troublesome  insect  pests  in  rose  growing  are  aphids  and  thrips, 
and  the  7/orst  fungous  diseases  are  blaclcspot  and  pov/'derj''  mildew.  Aphids  at- 
tach the  nev7  growth  or  the  soft  tender  shoots  below  the  bud.  Thrips  are  mora 
often  in  the  flowers.  They  are  the  cause  of  flowers  failing  to  open,  ttLrnin^' 
brown  and  withering  up.  They  are  particularly  noticeable  on  some  varieties, 
such  as  Mrs.  Francis  Scott  Key.  For  control  of  these  insects  use  Black  Leaf 
Uo  or  other  tobacco  extracts.  For  control  of  black  spot  first  make  a  thorough 
cleanup  of  the  fallen  leaves  and  follov;  with  an  application  of  lime-sulphi-r, 
or  Bordeaux  mixture  every  ten  da:;s  or  tv/o  weeks  \intil  the  trouble  is  under 
control.   It  is  better  to  keep  constantly  ahead  of  blackspot  and  insects  than 
to  wait  until  they  have  a  good  hold  before  starting  to  fight  them,  Black  spot 
is  a  matter  of  prevention  and  not  one  of  cure. 

Much  could  be  said  about  rose  varieties.  Some  growers  are  content  to 
grow  Radiance  only.   It  is  all  ri~J.it  to  grow  Radiance,  but  be  sure  to  try  some 
of  the  new  varieties. 

In  thir.  way  valuable  additions  inay  be  added  to  our  list.  Our  rose  gar- 
dens woulclbe  comnonplace  if  no  one  ever  tried  new  varieties.  For  instance,  if 
several  years  ago  no  one  had  eicpsrimented  v;ith  new  varieties  would  we  have  the 
Radiance  today?  Some  of  the  newer  varieties  which  we  tried  last  year  proved 
to  be  quite  successful,  such  as  E.  &.  Kill,  a  beautiful  dark  red  rose,  vigor- 
ous and  a  free  bloomer.  We  believe  it  is  going  to  be  as  popular,  if  not  bet- 
ter than  the  Etoile  de  Hollande.  Telisman  is  giving  good  results.  President 
Herbert  Hoover  is  decidedly  ?/orthwhile.  ^-.ile  it  resembles  the  Talisman,  it 
is  more  vigorous  and  has  longer  stems.  Betty  Uprichard,  a  two-toned  rose,  sen'ii- 
double,  is  very  vigorous  and  worthwhile.  We  consider  Kaiserin  Auguste  Vik- 
toria  the  best  white  rose,  better  f-ian  the  new  ones.  We  have  tried  Edel.  li 
did  not  stand  the  summer  very  well.  Dame  Edith  Helen  is  probably  the  most 
beautiful  pink  rose.  Blooms  are  very  large,  full-double,  pure  glov/ing  pink,. 
My  experience  shov/s  that  it  is  a  vigorous  grower  but  a  shy  bloom.Gr.the  first 
year.  The  second  year  the  bushes  look  scraggly,  and  the  blossoms  are  smaller^ 
Some  of  the  new  roses  vie   planted  last  season,  that  do  not  show  aiiy  ill  effects 
from  the  hot  weather  and  the  rainy  season  and  are  thus  highly  prized  are  iTidith 
Nellie  Perkins,  salmon  pinlc.  Editor  L'cFarland  is  a  verj"-  beautiful  rose,  a 
deep  even  pinlc  with  a  faint  tracery  of  white  i.ipon  the  edge  of  the  petals.   It 
inherited  its  vigor  and  productiveness  from  one  of  its  parents,  the  Radiance. 
Mrs.  Pierre  S.  DuPont,  blossoms  are  a  deep  golden  yellow;  one  of  the  best  yel- 
low roses  that  we  have  tried.  Anothsr  good  one  is  Ami  Quinard,  velvety,  crim- 
son maroon,  semi-double  blossoms  and  the  bush  is  of  extraordinary  vigor. 

If  you  are  after  new  climbers,  by  all  means  plant  MeriTiaid.   It  is  a  sin- 
gle rose  of  five  brilliant  white  petals  heavily  washed  with  gold  and  glorified 
by  a  great  burst  of  golden  stamens.  You  will  like  it.  We  also  have  in  our 
garden  climbing  Scorcher  and  Daydream  and  they  are  very  promising. 


Perhar-:;  some  of  you  do  not  know  that  there  is  a  rio"ida  Rose  Society, 
an  affiliated  unit  of  the  Araerican  Rose  Society*   The  qualifications  for  ciem- 
"bership  in  the  Florida  Ros3  Society  is  an  interest  in  roses  and  a  desire  to  know 
more  about  then. 

The   society  puhlislies  a  rose  hulletiii  annually.   ''&ro'"/ing  Roses  in

HAEDY  OHlTAIEiT^DilS  FOR  TH3  FLOE  IDA  GiEDSH 


Harold  Liowry,  Assistant  Director 
Florida  Experiment  Station 

Clims,tic  conditions  of  Florida  are  exceptionally  favorable  to  plsmt 
growth  and  this  accounts  in  large  .aeasure  for  the  ^;ealth  of  ornsumentals 
fotmd  in  the  state,  Fev;  other  areas  in  the  United  States  can  conipete  as 
to  variety  and  it  is  exceedingly  douhtful  that  any  other  state  can  boast 
of  a  near  a-oproach  to  the  wide  range  of  tropical  and  semi-tropical 
plants  found  within  its  borders.  The  numerous  native  plants  suited  to 
ornamental  usage  have  been  supplemented  with  introductions  from  all  con- 
tinents and  it  is  a  cons3rvative  estimate  that  no  less  than  a  thousand 
varieties  no-^  enter  in  one  form  or  sjiother  into  Florida's  lists  of  orna- 
mental plants. 

In  recent  years,  ornamental  gardening  has  received  a  great  impetxis, 
mainly  througij  the  efforts  of  the  statewide  org'?T.ization  of  Garden  Clubs 
whose  work  is  now  apparent  in  everjr  section  of  the  sts.te.  As  a  whole, 
the  value  and  desirabilit:"-  of  orna^aental  plaiiting  is  becoming  well  es- 
tablished but  thsre  are  yet  too  many  residential  lots,  homes  and  streets 
unjDlajited.  Some  few  owners  are  found  who  apiiarently  care  but  little  for 
the  beax^tificrition  of  their  home  grouiids.  Such  a  "ondition  is  q"'jlte  pro- 
bably due  in  large  measure  to  i.gnorance  of  plants  and  a  lach  of  apprecia- 
tion that  properly  ma.de  and  well  kept  plantings  not  only  enliance  the 
beautj?-  of  a  property  but  its  monetary  value  as  well.  A^ain,  the  planting 
of  ornamentals  is  neglected  in  man--  instances  because  of  a  lack  of  in- 
formation concerning  varieties  best  suited  for  specific  uses  and  their 
adaptability  to  the  different  areas  of  the  sta.te. 

It  is  discouraging  after  having  planted  shinibs  or  trees,  diligently 
cared  for  them,  throi^ghout  the  summer  and  fall  and  brought  them  into  a 
thrifty  growing  condition  to  have  them  severely  daiiiaged  or  killed  out- 
right by  cold  thi  following  winter.  Many  shrubs  and  vines  nay   be  killed 
to  the  ground  bji-  c./.d  but  will  spring  from  the  uninjured  roots  and  make 
a  vigorous  growth  the  following  summer.  Som.e,  however,  if  subjected  to 
severe  frosts,  may  be  killed  outright  ajid  to  prevent  such  losses  it  is 
advisable  to  plant  only  varieties  known  to  be  hard;''  in  the  locality.  For 
any  given  section  of  the  state  there  are  numerous  trees,  \'ines  and  shrubs 
that  are  climatically  adapted  and  sufficiently  hardj'  to  be  planted  with- 
ou.t  fear  of  cold. 

3y  the  term  hardiness,  as  referred  to  plaiits,  we  usually  have  re- 
ference to  their  ability  to  withstand  low  tenroeratures  without  appreciable 
damage.  Hardiness  seems  to  depend  on  several  factors,  araong  them:  the 
natural  cold  resistfince  of  different  species  and  varieties,  the  condition 
of  the  plant  as  to  health  and  dormancy  at  the  time  the  cold  weather  oc- 
curs, the  a.ge  and  size  of  the  plant,  temperatures  prevailing  previous  to 


-  2  - 


cold  periods,  ajid  possi'blj''  ritli  some  species  the  amoujit  of  s-jjishine  pre- 
vailing in  the  vfintsr  :-ionths.  Since  the  freezin:.;  process  in  plants  does 
not  cause  death  through  rupture  of  the  tissues  'out  primarily  throtigh 
?/ater  loss  in  the  cells  and  the  forraa.tion  of  ice  in  the  intercellular 
spaces,  it  appears  th?t  the  softer  the  grorth  and  the  greater  the  sap 
content  the  more  susceptilDle  is  the  plant  to  injurj'. 

To  a  degree,  pl?nts  may  he  enahled  to  -.vithstand  colder  temperatures 
if  it  is  possihle  to  "bring  them  into  a  condition  of  dormancy  prior  to  the 
advent  of  the  coldest  r;eather.  This  is  difficult  of  accomplishment  hut 
is  "believed  to  "be  aided  by  vritldiolding  "both  late  seasonal  cultivation  and 
late  applications  of  soluble  nitrogenous  fertilisers  and  "by   applying  some 
form  of  potash  salts  in  earlj;-  fall. 

Paradozical  as  it  may  seem,  growers  in  Florida  quite  often  have  cer- 
tain plants  severely  cold-da-maged  v/hen  the  same  varieties  are  unhurt  at 
points  one  or  two  hundred  miles  further  north  by  even  lower  temperatures. 
Such  conditions  evidently  are  occasioned  by  o'ox   fluctuating  winter  tem- 
peratures wherein  rather  extended  periods  of  v.-arm  weather  —  warm  enough 
to  prevent  complete  dormancy  or  even  cause  increase  of  sap  flow  or  ac- 
tual growth  —  are  follc-'ed  by  sudden  temperature  drops  that  are  damag- 
ing in  their  effect. 

Our  winter  sunshine,  too,  seems  to  have  its  effect  on  the  dormancy 
of  manjr  plants.  This  is  strihingly  brought  out  in  the  case  of  the  lit- 
chee  —  the  Chinese  tree  bearing  the  delectable  bright  red  fruits  that 
ap-oear  IVxe   clusters  of  large  strawberries.  This  tree  is  indigenous  to 
the  Canton  delta  region  of  China  "fhere  it  thrives  a:id  is  seldom  injured 
by  cold.  Canton  is  in  the  same  latitude  as  Havana.  Coconut  palms  are 
foimd  in  abrjidance  in  Havana  and  also  as  far  as  Palm  Beach,  which  is 
over  3-g-  6.egrees  northward.  Strangely  enough,  coconuts  do  not  grow  in 
CarAon   because  of  the  low  winter  teiiiperatures,  while  the  litchee  in  Flo- 
rida is  occasionally  injured  ^O"   cold.  The  difference  in  the  zero  point 
for  vegetative  growth  in  the  two  plants  offers  the  only  explanation  for 
their  difference  in  behavior.  The  litchee  evidently  is  stimulated  into 
a  flush  of  growth  at  about  60  to  $5  degrees  Fahrenheit  while  the  coconut 
requires  ^mich  higher  te-peratures.  A  comparison  of  sunshine  for  the  month 
of  February  of  a  given  year  showed  Canton  to  have  but  5'2  hours  for  the 
whole  m-onth,  while  southern  Florida,  with  a  higher  mean  ternperature  Vy 
about  7  degrees,  had  nearly  200  hours  for  the  saine  period.  Florida's 
fluctuating  temperatures  and  high  percentage  of  sunshir^r  days  make  it  vir- 
tually impossible  for  the  litchee  to  remain  dormant  and  as  a  consequence 
it  is  not  resistant  to  the  infrequent  periods  of  relatively  low  tempera- 
tures. Many  other  plants  fall  in  the  sam.e  category,  notably  the  Mexican 
lime,  gaava  and  r:iango,:"-ot  to  as  noticeable  a  degree  though  the  cold  sus- 
ceptibility is  similar. 

As  is  well  known,  the  degree  of  hardiness  in  pleats  varies  widely 
in  the  various  species.  Kost  plants  of  the  tropics  cannot  withstand  much 
cold  of  sustained  duration  and  shoiild  not  be  planted  in  those  areas  com- 
monly subjected  to  occasional  teniperatures  of  freezing  or  below.  Ordi- 
narily, there  is  no  pronoiinced  dormant  season  with  tropical  plants  that 
corresponds  to  that  of  the  plants  of  the  cooler  temperate  zones.  Some 
are  deciduous,  being  without  foliage  for  short  periods,  but  the  time  of 
leaf  shedding  r.-ia,y  be  induced  more  b:/  seasonal  drought  or  moisture  condi- 
tions than  by  temperature  alone.

T'ith  those  of  more  northern  states  and  tbe  co;:r-arisons  made  here  are  onl" 
for  the  -.r-ir-oose  of  calling  attention  to  terap^rature  variations  existent 
within  Tloricba. 

There  are  no  distinctly-  rnarhe:  bouzidarios  in  the  three  arbitrarily- 


named  p.reas  since  fev;  '^.'inter  seasons  are  identical  to  the  extent  that 
given  niiniimim  temperatures  of  one  '"inter  ca.n  "be  talren  a.s  an  exact  cri- 
terion of  the  cold  that  :oBy  "be   expected  at  a  designated  location  the  next 
yer>s.     Florida's  cold  weather  —  such  as  it  is  —  in  nearly'-  all  instances 
is  hrought  in  hy  northerly  rrinds  and  is  seldom  of  over  two  or  three  days' 
duration,  freezing  tenrperatures,  vrhen  they  do  occur,  rarely  last  over  a 
few  hours.  This  condition  allo-s  for  fairlj'  ".dde  differences  in  ter.ipera- 
ture  uiininiuras  even  in  closely  adjacent  localities.  Sovae  local  areas  are 
noted  as  "being  cold  "spots"  while  others,  "oecause  of  some  topographical 
protective  influence  a.re  well  knovm  as  warm  or  "frost-free"  locations. 

Because  of  the  teiTiperature  differences  obtaining,  three  factors 
should  he  given  consideration  in  the  choice  of  ornamentals: 

±irst:  The  relative  hardiness  of  the  plants  in  question. 

Second:  The  area,  the.t  is,  the  northern,  central  or  southern  area, 
in  which  the  plants  a,re  to  he  grown. 

Third:  The  local  situation  as  to  prohahle  protection  afforded  hy 
nearness  to  lalres  or  ocean,  hy  elevation,  or  hy  overhang- 
ing trees  and  nearhy  "buildings. 

Due  to  the  extremely  large  number  of  ornamentals  p.vailahle  for  Flo- 
rida planting,  it  is  iru^ossihle  in  the  time  allotted  to  give  anj'-thing  lihe 
a  comprehensive  list  of  those  adapted  to  the  different  sections.   In  many 
instances,  ohservation  of  those  plants  growing  in  the  vicinity  will  give 
a  good  idea,  as  to  the  ones  adapted  to  that  particular  area.  Quite  reli- 
able inform.^tion  as  to  the  clima.tic  adaptability  of  the  n^omerous  varie- 
ties mp.y  also  be  had  from  the  inany  nurser-'men  who  grow  ornamentals.  The 
Experiment  Station,  too,  has  a  list  of  nan;'  of  the  :nore  co:.imon  plants, 
arranged  as  to  haj-diness,  that  riay  be  had  for  the  ashing. 

The  questions  of  hardiness  and  adaptability  of  the  plants  to  be  used 
about  the  home  and  in  the  garden  are  of  paramount  importance  and  should 
be  given  due  consideration  in  ga.rden  plans  since  the  ultimate  success  of 
the  planting  v;ill  depend  largely  on  these  factors.

THE  PRDPAGATniT  OF  GARLEIJ  PL.AITTS 


John  7.  'Yatkins,  Asst.  Horticulturist 
University  of  Florida,  College  cf  Agriculture 

In  the  growint^  of  anything  some  -olans  have  te  he  made  for  Tcroetuating 
the  kind.   This  wq   call  •■jro-jagation,  and  it  is  one  rf   the  important  jobs  in 
tiie  having  of  a  fine  garden.  Most  gardeners  leave  a  lot  of  the  task  cf 
•oropagation  U")  to  nurserymen,  who  make  a  speciality  of  that  work,  but  there 
are  many  who  get  great  satisfaction  in  or o-)agating  many  of  their  own  garden 
olants.  KnO'viedge  of  hci7  the  different  kinds  of  -jlants  are  ^rooagsted  is 
really  a  -jart  of  good  gardening. 

Plant  "orroagation  may  be  defined  as  the  incra^se  in  plants  tc  r)enetuate 
the  species  or  the  variety.   It  involves  the  art,  the  science  and  the  knowledge 
of  the  best  time,  ilace  suid  manner  ©f  -)ror)Sgating  each  kind  of  -olant.   The  art 
may  be  acquired  by  following  an  exa-.nle,  either  written  or  manual,  or  by  the 
trial  and  error  method.   The  science  may  be  acouired  from  b-joks  or  from  an 
ex-)erienced  gardener. 

Methods  of  Tro^agation  divide  themselves  into  t"'o  general  classes  - 
sexual  and  asexual,  the  sexual  method  id  dependent  on  the  -formation  of  seeds, 
and  the  asexual  method  is  used  when  seeds  are  not  available.  Under  the  asexual 
classification  we  should  consider  the  various  tjnes  of  prorjagation,  such  as 
division,  cuttings,  Inyerage,  bulding  and  grafting. 

In  this  oa-'Der  we  will  consider  only  th«i  planting  of  seeds,  division, 
cuttings  and  layerage,  and  will  omit  the  mere  technical  discussion  of  budding 
and  grafting. 

The  olant ing  of  seed  is  by  far  the  simoliest  and  most  used  method  cf 
Tjrooagating  flowering  olants.   That,  hs'-^ever,  is  a  much  bigger  job  than  just 
sticking  a  few  seed  in  the  ground  and  covering  thera.   There  is  a  time  to  '^lant 
them,  certain  soil  to  olant  them  in,  a  depth  tn  cover  them,  and  they  need  the 
right  amount  of  moisture. 

We'll  discuss  the  planting  of  seed  in  more  detail,  but  mw  sup-ooso  w<» 
discuss  some  of  the  more  interesting  asexual  methods  of  orcrjagation. 


-  2  - 

Division:    Propar^aticn  "by  division  is  the  easiest,  quickest 
and  best  way  to  increase  most  herbaceous  perennials,  and  many  btilbs. 
Dig  the  plants,  shaJce  off  the  dirt  and  it  will  be  apparent  t  iit  they 
v/ill  divide  up  into  units  or  small  plants  all  having  roots,  stems,  buds 
erlieaves.   These  units  may  be  separated  and  planted.   The  beds  should 
be  thoroughly  prepared  beforehand  and  abundant  water  should  be  added 
to  pack  the  soil  well  about  the  roets.   Plants  are  best  divided  aftor 
the  blooming  season,  but  with  care  thej^-nay  be  so  increased  at  any  time. 

Cuttini'-2;s:    This  method  also  is  much  used  in  the  propagation  of 
perennials  and  it  is  not  at  all  difficult  if  a  i^ood  grade  of  sharp, 
clean  sand  and  plenty  of  ''ater  are  used. 

Old  stems  are  cut  in  three  or  four  inch  len,i;ths ,  just  above  and 
■ust  b«!low  convenient  nodes  or  buds.   The  leaves  on  the  upper  nod© 
should  be  left  intact.    A  sharp  Jniife  that  will  make  a  clean  neat  cut 
is  the  best  tool  t  1  use  in  nakin,-^  cuttin.-s. 

A  flat  or  box  of  any  convenient  size  in  the  bottom  of  which 
several  holes  have  been  drilled  to  allow  the  free  pasGa;^e  ^f  watar 
is  an  ideal  receptacle  for  the  rooting  of  c\ittings.   Cover  the 
drainage  holes  v/ith  coarse  material  so  t]i;it  the  sand  "ill  not  wash 
through.    Fill  the  box  with  coarse  sand  to  wit  in  an  inch  'f  the 
top;  pack  well,  insert  the  cuttings  to  tiie  upier  nodes,  and  water 
to  firm  thesand  about  the  cuttings.    Shade  the  flat  and  keep  the 
sand  moist  at  all  times.     'iTlieii  the  roots  are  aloout  one  inch  long, 
set  the  youn,^  plants  in  fertile  soil  that  can  be  readily  watered, 
and  protect  them  from  thehot  s-on  or  cold  until  they  are  well  es- 
tablished. 

Dormant  hardwood  cuttings  of  garden  shrubs  may  be  made  in 
eight  or  ten  inch  lengths, tied  in  b\mdles  and  buried  in  sand  upside 
down.   When  inspection  sho^fs  that  a  callus  has  fonned  on  the  basal 
end,  the  cutting  may  be  lined  out  in  nursery  rows.   They  are  set  so 
that  only  one  or  two  buds  are  above  the  i';round  level    The  moisture 
must  be  adequate  and  constant  if  a  good  percenta;x«  of  well  rooted 
plants  is  expected. 

Layerage  is  that  method  of  propagation  in  which  plants  are  in- 
creased by  rooting  their  stems  wif,:ou.t  detaciiing  them.   When  these 
stemiS  are  well  furnished  witJi  roots,  they  are  sever-^d  and  the  new 
plants  are  transplated  as  individuals.   Uany  of  our  woody  and  semi- 
woody  garden  plants  aremost  easily  propagated  by  layering,  which  is  a 
favorite  method  ™ith  many  gardeners  because  successful   increase  is 
practically  assured. 

Simple  layers  ars  m-if'e  by  bending  down  the  lower  branches  of  a 
plant  so  that  it  coraei.  into  contact  with  the  soil.    Usually  a  trench 
is  made  to  receive  the  stem  which  has  boen  notched  or  nicked  witn  a 
]-3iife  to  facilitate  rootin-^-.   After  the  soil  has  been  leveled  and  firm- 
ed over  the  branch,  a  peg  or  a  brick  is  used  to  hold  the  layer  in  place. 
Frequent  watf^ring  is  m»st  important  to  insure  tlie  quick  development  of 
an  adequate  rcot  system. 


-  3  - 

Continuoufj  layers  are  tliose  in  which  ^'hole  steir.s  or  canes  are 
b-'oried  ujader  a  few  inches  of  sand,   ITe"  plants  arise  from  eyes  or 
buds  along  the  anes.    The  rnet^'-od  cannot  be  \iEed  witli  many  -plants, 
and  evpn  those  th.--t  may  te  increased  in  tl'.is  ^"'ay,  do  not  produce  large 
numbers  of  progeny. 

Chinese  layerin,^  is  a  popular  method  used  in  increasing;  plants 
vrhose  branches  cannot  be  bent  donn  to  the  ground.    The  stems  are  notch- 
ed where  the  root  systeu:  ie  ^'anted  and  the  voujided  area  is'  boimd  tight- 
ly in  a  wad  of  sphagnum  moss,  fibrous  peat  or  other  moisture  holding 
materirtl.    String,  tape  or  raffi.a  is  wrapped  round  and  round  the  wad 
to  hold  it  firmly  in  placf^.   Freqxient  watering  of  the  layer  is  essen- 
tial.  iJhen  roots  begin  to  eraerge  tlirough  th.e  ball  of  moss,  the  nevi 
plant  should  be  severed  and  potted  as  an  individual.   Chinese  layers 
are  used  to  ma'ce  neif  root  systems  on  potted  or  tubbed  specimens  that 
have  become  l=ggy.   Pots,  cans  and  cups  of  various  materials  may  be 
used  in  this  type  of  layering,  especially  if  soil  is  preferred  to  moss 
as  thc>  rooting  medium. 

Pljjnt_ing  See_d_s^    The  one  item  of  greatest  difficulty  with 
most  gardeners  is  gettin.'^  a  good  stand  of  seedlin''-:s  and  protecting  them 
from  the  dreaded  disease  known  as  "d;"jnping  cyf".   During  August, 
September  and  Octcbir,  when  most  annual  seeds  are  planted,  the  warm 
weather  is  very  favorable  to  tae  growth  of  d.ara;oing  off  organisms  and 
the  loss  of  seedlings  is  tremendous,  if  pro-^er  precautions  arenot  ob- 
served. 

There  are,  perhaps,  as  m'vny  different  methods  of  planting  seeds 
as  there  are  gardeners.   The  method  describee  herevrith  has  been  used 
successfully  at  the  horticultural  grn-ijids  of  the  Col"^^.ege  of  Agricult-'ore 
for  the  last  five  years,  and  chough  it  isnot  necessarily  the  best  way 
to  plant  seeds,  it  has  proven  very  satisfactory. 

First  of  all,  the  autumn  sown  annuals  ma^'  be  divided  arbitrarily 
intc  two  classes  -  thos-i  which  transplant  readily  and  those  v/hich  do  not. 
Seeds  of  the  former  are  planted  in  flats,  vuiile  those  of  the  latter  are 
sewn  in  the  open  groujid  where  the  plants  are  to  stand. 

The  flat  may  be  a  shallev;  box  of  any  convenient  size  th.  t  has 
plenty  of  drainage  holes  or  cracks  in  the  bottom  to  allow  water  to  pass 
freely  out  of  the  soil.   Thorough  drainage  is  exceedinglj'-  important  in 
soils  where  tender  seedlings  are  grown,  as  a  scur,  water-logged  soil 
is  fatal  to  most  young  garden  plants.    In  the  bottom,  of  the  flat  should 
be  placed  a  layer  cf  pine  straw,  dead  grass  clip'jings  or  other  cor.rse 
m.n,terial  so  that  the  soil  will  not  wash  through  the  drainage  holes. 

The  soil  used  in  flats  may  be  any  good  grade  of  garden  soil 
v;hich  contains  a  fair  pjnctmt  of  well-rotted  organic  matter  such  as  cow 
manure,  oalc  leaves,  peat  moss,  etc.   The  older  the  soil  is,  the  better. 
Soil  th-it  is  free  from  root-'mot  nem'-.todes  is,  of  cours'=,  desirable. 

Firm  the  soil  to  '-^ith.in  half  an  inch  of  the  top  of  the  flat  Avith 
a  brick  or  a  block  cf  wood.    Flood  this  gently  packed  soil  with  a  solu- 
tion of  one  of  the  organic  mercury  compounds  tliat  are  indicated  for  the 
control  of  damping  o*'f.    After  this  solution  h.is  drained  off,  sift 
the  seqds,  broadcast,  on  the  wet  soil.    Cover  lightly  by  sifting  sand 


-  4  - 

thro^jgh  a  screen 
or  sandy  soil/ over  the  seeds.   Coverin.T  the  seeds  too  deeply  is  a  common 
error.    Generally  spe,ak:ing  if  tlie  seeds  be  just  barely  hidden  good  re- 
sults may  be  expected.   After  the  seeds  have  been  covered  T'it;:  soil,  pl;\ce 
a  V7et  newspaper  over  the  flat.   'Tater  should  be  sprihlcled  on  the  paper 
whenever  it  becomes  dry.    In  this  '•ay  there  if5  no  d;ui^er  of  ^ashin.'^  th-- 
seeds  out  of  t]ie  soil,  and  the  soil  is  l:ept  uniformljr  moist.    The  v/et 
ne^7Spaper  should  remain  on  the  flat  until  the  seeds  jC^erminate.   Place  the 
.flats  on  boxes  or  benches  that  are  protected  from  ants  vrhich  often  carry 
ai-'ay  the  seeds.    Some  of  the  most  popular  of  our  autumn-sown  annuals,  such 
as  pansies,  snapdragons  and  larkspur,  are  cool  v.-eather  plants  and  their 
seeds  vrin  not  germinate  readily  if  the  temperature  is  excessively  hif;h. 
Forthis  reason,  to  assure  a  fair  stand,  it  ib  im.po:'tant  that  the  flats 
should  be  placed  in  the  coolest  possible  situation.    The  north  side  of 
a  buildin.^,  under  a  tree,  or  under  an  open  shed  should  do  nicely. 

i-fter  ^erm.ination  the  flats  must  be  placed  '^here  the  seedlinfCB 
can  /^et  an  ab'judance  of  lif;ht;  if  tliey  are  left  in  the  shade,  the  seedl- 
ings \7ill  grov  into  weak,  le.'^gy  plants.   We  have  found  that  a  muslin 
shade  such  as  is  used  for  celery  or  tobacco  seed  beds  allor's  sufficient 
light  to  penetrate  to  the  young  plants.   Shortly  after  germination,  the 
flats  should  receive  another  application  of  a  compound  for  the  control 
of  damping-off .   !7ater  sho-ld  be  carefully  applied  through  a  fine  spray. 

Tnen  the  seedlings  sho^'  abou".  four  true  leaves,  they  may  be  trans- 
planted to  i,7ell  prepared  beds  vfhere  they  are  to  bloom.   Choose  a  cool, 
cloudy  afternoon  for  transplant  in":  if  it  is  at  all  possible,  and  set  the 
plants  about  12  to  18  inches  apart.    Clcse  planting  is  desirable  to  assure 
bold  color  masses.    As  further  insurance  a/^ainst  damping  off  it  is  often 
a  good  plan  to  use  the  d;imping-off  control  iirmediately  after  transplanting. 
Great  care  sho^jld  be  exercised  in  ^7atering  the  yc^-Xip;   plants  until  they  are 
nell  established.   Ovor'-'aterin,'^  can  be  as  harmful  as  under-natering. 

The  second  class  of  annu-als,  thrse  "hich  are  planted  in  the  open 
ground  nhere  they  arp  to  bloom,  may  be  haxxdled  much  the  same  as  vegetables. 
Sovr   the  seeds  tJiinly  in  siiallov  drills  or  trenches.    Cover  lightly  nith 
soil  and  sprinlcle  i-'ith  a  dairiping-off  control.    The  drills  or  rons  may  be 
covered  vith  vet  strips  of  b^orlap.    If  t.iis  material  is  used  '■'ater  irill 
not  vash  the  seeds  out  of  the  soil,  pjid  the  soil  stays  uniformly  moist. 
If  ants  are  abundant,  grits  or  ccrnmeal  she  Id  be  sprin3cled  liberally 
alcng  the  rovs.   These  '-'ill  be  talcen  in  preference  to  tlie  seeds.   As 
soon  as  thp  seeds  germinate  the  burlap  must  be  removed  and  a  second  appli- 
cation af  the  d,-mping-of r"  control  she  Id  be  made.   Wlien  the  plants  are 
\'ell  established,  thin  s&  th.-.t  they  stand  about  12  to  18  inches  apart. 

In  summing  up,  v/e  might  say  tliat  the  one  bi-  thing  to  bear  in 
mind  in  propagating  plants  is  that  different  plants  demand  different 
Kethods  and  it  is  up  to  the  gardener  to  learn  the  likes  and  dislikes 
of  their  different  kinds  of  plants.   When  plants  are  considered  as 
individuals  and  something  ni'th  life  in  them,  the  gardener  is  rauc  i  more 
likely  to  be  successful  in  having  a  fine  garden.

DECIDUOUS  TREES  FOR  THE  FLORIDA  LAITOSCAPE 

&.  H.  Blackmon,  Horticulturist 
Florida  Agricultural  Experiment  Station 

Trees  occupy  an  iiriiDortant  place  in  any  well-c.esij_;ned  and  executed 
landscape  planting.   They  function  as  does  the  frame  of  a  picture,  and 
bring  out  the  lines  and  'boundaries  with  the  proper  setting  so  that  the 
full  and  complete  effect  of  the  other  plant  material  is  developed.  Rest- 
ful breal:s  can  be  established  along  roadsides,  in  parhs,  estates  and 
countr^r  club  grounds  with  the  proper  use  of  the  right  trees. 

Ornamental  trees  should  be  selected  for  their  indivic.ual  ability  to 
produce  certain  definite  and  desired,  effects.  Evergreen  trees  are  often 
used  because  of  their  beautiful  gTeen  appearance  during  the  dormant  sea- 
son, but  there  are  many  locations  and  types  of  plantings  where  it  is  more 
desirable  to  use  other  Lind.s,  Trees  for  shad.e  and.  beauti''  during  the  suith 
mer  months  are  required  on  practicalljT-  all  si-nall  home  ground.s.  Where  the 
full  benefit  of  the  Florida,  sun  is  desired  during  the  v/inter  months  de- 
ciduous trees  are  the  most  satisf actor"  ones  to  plant.   With  proper  selec- 
tion and  arrangement  it  is  possible  to  meet  adequately  such  requirements 
with  a  great  variety  of  trees  that  shed  their  leaves  during  the  dormant 
season  so  as  to  admit  practical "13'  all  of  the  auilight  during  the  time  when 
it  is  most  desired. 

There  are  man"  t"pes  of  la.ndscapes,  especially  those  of  large  propor- 
tions, v\here  deciduous  trees  can  be  used  most  effectively.   Cclor  combi- 
nations in  foliage  and  flowers  of  exquisite  beauty  can  be  produced  in 
great  abundance  during  the  spring  and  autumn  by  the  correct  arrangement 
of  such  trees  in  the  planting.  Colors  in  great  array  are  ma.gnificently 
portrayed  in  the  natural  woods  of  Florida  dui'ing  the  spring  and  fall 
months  when  the  foliage  of  persiminons,  oalzs,  sweet  gums,  maples  and  ithers 
in  gorgeous  hues  blend,  harrroniously  with  the  green  of  the  pines.  After 
all,  what  is  more  beautiful  than  the  natural  landscape  upon  which  all  suc- 
cessful plans  must  be  based  if  suitable  audi  pleasing  surroundings  are  to 
be  developed. 

There  are  tv;o  general  types  cf  deciduous  trees  adaptable  to  Florida 
landscapes.  Those  that  shed  all  their  leaves  during  the  fall  and  those 
that  shed  their  leaves  during  the  latter  pert  of  the  dormant  season  and 
become  completely  defoliated  just  before  or  about  the  tiiae  of  the  initial 
sirring  flush  of  growth.  The  native  cherry,  red  oalt,  hich-jry  and  pecan 
are  representative  trees  of  the  first  group,  while  laurel  and  water  oalrs 
re-oresent  the  latter. 


The  soils  required  for  deciduous  trees  are  much  the  same  as  those 
for  t'^e  general  ulantings  ma.de  in  landsca^oe  arra.ngements.  Therefore,  if 


Page  two . 


a  gcoc  lawn  rnr'.  shrub  soil  is  available,  fiOod  results  will  be  hac'.  in 
planting  rnc.  ;;:;ro'ving  trees  ada;"ted  to  Florir.a  conditions.   In  general  the 
land  shoulc  be  well  drained,  but  of  sucli  condition  that  it  will  retain 
surrficientjmoisture  that  rnaxiinam  results  will  be  obtained  from  the  water 
supply  and  vigorcus  growth  of  the  trees  maintained. 

Transplanting  is  done  during  the  dormant  season  according  to  the 
general  rules  for  setting  trees.   The  holes  should  be  large  enough  to  ad- 
mit the  roots  without  crowding  and  to  a  de-th  that  will  allow  the  roots 
to  be  as  dee'^  as  the:"  were  in  the  nursery  or  in  their  natural  Iccaticn. 
In  setting  the  trees  it  is  best  to  plant  with  the  roots  no  deeper  than 
they  grew.   Use  onlj"-  top  soil  and  press  it  firmly  about  the  rrcts  and 
add  about  one  ^ocund  of  bone  meal  as  the  holes  are  being  filled.   Wlien 
the  holes  are  three-fourths  full,  water  thoroughly  and  then  fill  in  with 
loose  earth.   The  tops  of  the  trees  should  be  cut  bac.'c  rather  severel-"-  to 
balance  with  the  root  systems  at  the  time  the  trees  are  trans-olajited. 

Tyiien  trees  are  rem.oved  from  their  natural  loc?tions  one  should  talre 
up  as  gooc"  a  root  system  as  possible  and  'orotect  it  from  drving  ^'inds  and. 
suji  with  damp  moss  or  buxlap  until  trans^^l^nted.   The  root  s'",''stem  on 
trees  with  ti'nn.zs  not  over  two  or  two  and  one-half  inches  in  dirraeter 
should  be  not  less  than  twc  feet  across,  three  feet  is  better,  and  the 
roots  shovid  have  a  depth  length  of  IS  to  36  inches,  deyending  u;-)on  the 
kind. 

The  size  of  trees  that  will  give  the  best  results  after  trans-planting 
is  an  imuortant  item,   ITursery-grown  trees  are  graded  by  feet  up  to  12 
feet  high  and  by  cali-^er  of  trun',:  in  inches  for  larger  grades.   Most  trees 
will  grow  off  inach  better  if  medium  sizes  are  selected  rather  than  the 
extremely  Irrge  ones.   Pecans,  hichories  and  walnuts  in  general  should  be 
of  the  5  "to  6  foot  or  6  to  o  foot  grades  or  smaller,  althougli  trees  as 
large  as  3  to  10  feet  can  be  successfully  -^la.ited  about  the  home  where 
individual  attention  can  be  given  them.   Per  other  kinds,  trees  with 
trunlcs  not  ever  two  and  two  and  cne-half  inches  in  diameter  should  be 
planted,   although  water  oaks  up  to  U  to  6  inches  in  dirmeter  often  are 
trans^olanted  successfully  with  b^re  roots. 

Trees  in  the  landscape  ordinarily  receive  little  or  no  cultivation, 
as  it  is  generally  desired  to  hpve  the  lawn  grass  completely  covering  the 
ground.   There  are  some  species,  notably  the  pecan,  that  will  grow  off  to 
a  much  better  ?d.vanta.ge  if  a  small  ajrea  about  the  ba.se  is  ?:ept  clean  of 
growing  vegetation  and  mulched  with,  organic  material  for  the  first  two 
or  three  -"-ears.   This  latter  |)ractice,  however,  is  not  so  importajit  if 
the  trees  are  located  in  lawns  that  are  r.snt   ^"ell  watered  and  fertilized. 
Adequate  soil  moisture  must  be  maintained,  otherwise  the  trees  will  not 
make  suitable  growth. 

A  general  fertilizer  a-ial-"-zing  about  ^-J-^   should  be  applied  in  the 
s-ring  and  a-^ain  in  the  su.nmer  to  su'tcI"  plant  foods  in  sufficient  amounts 
to  produce  "rowth.  Bone  meal  and  cottonseed  meal  are  also  good  materials 
to  use  on  th:;  soil  in  which  shade  trees  are  growing.   If  the  lawns  in 
which  trees  are  located  are  prc-'erlv  fertilized  during  the  growing  sea- 


Pa^e  three. 


son  it  will  not  oe  necc-ssarv  to  nir>::e  additional  applicE.tions,  but  it 
would  bii  advisp'ole  to  increase  the  ^motmts  some'^hat  in  the  areas  occu- 
pied bv  the  tree  roots.   If  trees  are  to  be  ^iven  special  fertilizer  in 
lawns  it  is  best  done  by  plugging,  i.e.,  punching  holes  in  the  earth  in 
the  root  zone  and  filling  with  fertilizer,  preferably  bpne  meal. 

The  pruning  of  deciduous  trees  shoulr".  be  generally  attended  to  dur- 
ing the  dormant  season  which  in  Florida  is  approxima.tely  from  December  to 
March.  About  rll  that  need  bs  done  is  to  prune  out  any  dead  ajid  inter- 
fering brajiches.   All  TDinining  should  be  'one  so  that  the  cut  is  made 
next  to  another  branch  or  where  the  limb  joins  the  tr\i:il;  of  the  tree  to 
insure  oropsr  healing  of  the  wound.  When  removing  dead  limbs  the  cut 
should'  be  made  well  into  the  green  wood  area.   The  cuts  should  be  made 
■••ith  a  sha.rp  saw  a.nd  in  such  a  way  as  to  avoid  splitting.   All  cut  sur- 
faces of  more  thaji  one  inch  in  diameter  should  be  covered  with  a  good 
grade  of  outside  paint  or  wound  dressing  to  prevent  the  entranice  of 
moisture  and  wood-rotting  fungi.  Decaying  wood  that  started  from  brolien 
or  poorl-"-  -nrunsd  branches  a,nd  unprotected  cut  surfaces  has  ca^used  the 
weplcening  and  death  of  many  trees  that  otherwise  would  have  lived  for  a 
much  longer  period. 

Trees  ma.-"-  become  unsir-ptl'"  and  lose  their  vptility  and  usefulness 
due  to  attac^:s  of  insects  ajiid  disea,ses,  a.nd  gardeners  should  be  prepared 
to  prevent  such  losses.   Complete  information  regarding  control  methods 
of  destructive  -pests  can  be  obtained  from  the  University''  of  I'lorida  Ag- 
ricultural Ex-^^riment  Station. 

There  are  a  Ifrge  nu^riber  of  deciduous  trees,  both  introduced  and 
native,  from  w'lich  Florida  gardeners  ma.y  select  ma.toria,l  for  planting. 
The  native  trees  are  sufficientl^r  numerous  to  fulfill  almost  a.ny  renuire- 
ments.   There  .^re  numerous  oalts,  svcamore,  cvoress,  sv;eet  gum,  ma.ples, 
hiclcories  and  others  native  to  Florida  that  are  excellent  trees  for  land- 
scape and  street  plantings.  There  are  also  majiy  introduced  trees  w'-'ich 
should  not  be  overlooked  that  thrive  satis;'actorily  when  properly  located, 
includ-ing  G-inl:go,  Koelreuteria  formosana,  Aleurites,  Pecan,  Blacl;  Walnut 
a.nd  rna.ny  others. 

Laurel  and  water  oaJis  are  probabl;"'  th.ciriost  commonly  used  sf  all  de- 
ciduous trees  for  roadside,  street  and  la.ndscape  plantings.  The  red  or 
Spanish  oalr  gives  good  results  and  is  often  left  v/hsre  growing  nrturally 
when  clearings  arelpiade.  All  of  these  mal:e  beautiful  trees  aaid  furnish  a- 
bundant  sha.de,  but  the  last  naaaed  is  the  only  one  thnt  sheds  the  leaves 
completely  in  the  fall,  the  other  two  being  more  or  less  tardily  decidu- 
ous. 

The  Bald  cypress  anr'  the  Pond  c^^ress  are  t'"o  coi.iinon  native  decidu- 
ous conifers  that  can  be  trans-olaiited  and  gTown  successfully  as  ornajnental 
trees.  Thev  present  a  ver-r  beautiful  appearance,  especially  in  the 
sriring  when  the  new  grc-th  has  the  light  green,  feathery  appearance. 

The  Svcanore  is  i-il-'^ntec'  a.s  a  shade  troe  to  some  extent  throughout 
the  northern  areas  of  Florida  where  it  thrives  satisfactorily.  O'-dng  to 
its  grayish  white  barh  it  can  be  used  effectively  where  it  is  desirable 
to  have  r.   tree  that  will  show  ai".iong  or  against  a  ma.ss  of  green  foliage. 
Some  object  to  its  leaves  as  the^/  fall. 

Sweet  Gum  is  another  native  tree  that  is  found  throughout  most  of 


Florida  that  is  a  vigoro'As  jjrov-cr.   It  is  pjTCjrdJ'-al  in  general  shape, 
tall  and  well  suited  for  roadside,  avenue,  and  group  planting s  where  such 
deciduous  trees  are  desired.  The  foliage  is  dense  and  turns  to  shades  cf 
"beautiful  reds  and  yellovz-s  in  the  late  fall  months. 

The  Red  maple  which  is  native  over  Florida  from  the  southern  parts 
through  to  the  northern  areas,  is  used  to  some  extent  in  ornamental  plant- 
ings.  It  presents  a  bea.utiful  appearance  in  the  s-pring  a.nd  the  folia.ge 
turns  to  bright  red  and  yellow  colors  in  ths  fall,  which  malces  it  very- 
attractive.   This  tree  should  he  emplo:7ed  more  extensively,  as  it  trans- 
plants easily  and  is  well  adapted  to  natural  conditions  where  the  soil 
is  suited. 

Native  hicliories  are  not  generally  transplanted,  but  are  frecuently 
left  as  specimen  trees  when  clearings  are  made.   They  are  beautiful  trees, 
especially  Hicoria  alba,  and  Hicoris.  glabra,  and  lend  much  dig:iity  and 
beautj?-  to  landscapes.   The  Water  hiclcory,  Hicoria.  aquatica,  can  be  trans- 
planted successfuJLly  and  is  es"oecially  valuable  in  rather  wet  locations. 

The  pecan  is  planted  extensively  as  a  shac'e  tree  throiighout  central 
and  north  Flori'^a.   The  l?rge  trees  frequently  noted  about  the  homes  in 
the  state  are  .nostly  seedlings,  but  the  later  plantings  are  mostly  of 
named  varieties.  With  the  pro"Der  varietv  it  is  possible  to  have  orna- 
mental she.de  trees  t'lat  will  also  produce  a  supply  of  nuts  for  home  use 
and  for  sale. 

The  Maiden  hair,  or  GiiiI:go  biloba,  is  planted  sparingly  as  an  orna- 
mental tree  in  the  northern  part  of  the  state.   It  presents  a  pleasing 
appearance  during  the  grov^ing  season,  and  again  in  the  late  fa,ll  when  the 
foliage  turns  to  a.  golden  yellow.   As  the  fruit  has  a  foul  oder  it  is 
best  to  plant  only  those  trees  bearing  the  stajninate  flowers. 

The  tung-oil,  Aleurites  fordi,  introduced  from  China,  presents  a 
a  beautiful  appearance  in  the  spring  when  in  full  bloom.   It  is  also 
rather  attractive  as  a  foliage  tree  during  the  summer^nonths  but  owing  to 
its  habit  of  growth  it  would  be  best  suited  as  a  part  of  the  ba.nks  and 
clumps  of  sniall  trees  rrther  than  in  a  location  where  an  extremely  large 
stately  specimen  is  desired.   Other  species  which  are  planted  to  some  ex- 
tent in  the  southern  part  of  the  sta^te  a.re  Alexirites  montana;  A.  moluc- 
cana;  A.  cordata;  and  A.  trisperma. 

Koelreuteria  formosana  is  as  yet  quite  rare  in  Florida,  but  succeeds 
as  an  ornamental  deciduous  tree  on  well-dradned  lands  over  most  of  the 
state.   This  is  a  flowering  tree  that  can  be  utilized  effectively  where 
color  is  desired  in  the  late  summer  and  fall.   It  produces  great  panicT.ps 
of  small  yellow  flowers  that  appear  in  late  September  and  early  Octobe: 
followed  by  the  red  capsules  containing  the  seed.  The  colors  are  very 
showy  and  attractive  and  the  trees  can  be  used  in  numersous  ways  in  va- 
rious sized  landscapes  and  home  grounds. 

There  j»re  two  walnuts  that  are  used  to  some  extent  as  j'-ard  trees 
that  thrive  in  central  ajidnorth  Florida.   The  Blaclc  walnuts  make  beauti- 
ful shade  trees  of  considerable  proportions  that  a.re  quite  useful  as  well 
as  ornamental.   The  seedling  Japanese  walnut  is  found  growing  about  homss 
less  frequently  than  the  Black  walnut  and  is  a  iruch  smaller  tree.   Nuts

v,-ith  delicioiis  kernels  are  produced  in  aliundance  "by  both  of  these  wal- 
nuts which  adds  materially  to  the  home  supply. 

There  are  man;"-  decidiious  trees  other  than  those  mentioned  and  hrief- 
ly  described  that  can  be  successfully  used  in  Florida  landscapes  and  for 
street  and  roadside  lolr.ntin^^js.  Much  fuller  lists  with  complete  descrip-

ORi-JAI.EHTAL  FLORIDA  FRUIT  TRE-^IS 

By 

H.  S.  "finite,   Hortictilturist  in  Charge, 
Sub-Tropical  Experimtnt  Station,  Homestead,  Fla. 

To  the  prosr)ective  orcliardist  the  only  considerations  entering  in- 
to the  selection  of  fruit  trees  are  the  quantity  and  quality  of  fruit 
to  be  expected  and  the  market  returns,  but  to  the  home  owner  who  wishes 
to  have  a  few  fruit  trees  arci-ind  his  house  it  is  of  interest  to  know 
what  ones  will  serve  an  ornamantal  function  as  well  as  provide  frmt 
for  his  table.   Florida  has  no  fruit  trees  which  make  such  a  striking 
display  as  northern  aople,  cherry  or  peach  trees  in  the  spring,  yet 
there  are  maxiy  among  Florida's  fruit  trees  which  are  as  well  worth  grow- 
ing for  their  ornamental  value  as  for  their  fruit.   In  nearly  every  case 
they  are  attractive  the  whole  year,  instead  of  having  only  a  relatively 
brief  period  of  loveliness  in  the  spring. 

Most  of  the  attractive  fruit  trees  of  Florida  have  ornamental  va- 
lue chiefly  because  of  their  comosctly  sjTTnmetrical  habit  and  their  ever- 
green foliage.   In  a  state  v.-here  so  many  brilliantly  colored  shrubs  and 
vines  abound,  it  would  almost  seem  enough  to  ask  that  fruit  trees  should 
be  handsome  evergreens.  But  of  the  three  F's  of  ornainental  value  — 
flowers,  fruit  and  foliage  —  we  have  some  fruit  trees  with  all  three 
and   some  with  two,  a.s  well  as  those  with  only  handsome  foliage  to  re- 
commend them  as  ornamentals. 

Perhaps  the  best-known  examples  of  fruit  trees  with  a  triple  F  for 
ornament  --  attractive  flov/ers,  colorful  fruit  and  beautiful  foliage  — 
a.re  found  a/aong  the  citrus  S'-ecies.   The  waxy,  white  flowers,  with  a  de- 
lightful fragrance,  are  set  off  in  s--rrinj-  by  the  background  of  glossy 
green  foliage,  while  in  winter  the  same  berutiful  green  serves  again  as 
setting  for  the  yello-ff, -.orange  or  red  fruits.   The  most  ornamental  of 
the  citrv.s  family  is  the  kumquat,  whose  numerous  fruits,  like  orsjige- 
•^■■ellow  plums,  adorn  the  sha-oely  little  trees  for  months.   Of  slightly 
larger  habit  and  more  spreading,  willov;y  branches  are  the  tangerines, 
whose  fruits  are  the  size  flf  small  apples  and  var'"  in  color  from  brig^'^t 
orange  to  a  decided,  red,  according  to  the  variet-".  Fnile  it  is  more 
difficult  to  obtain  and  keep  symmetrical  specimens  of  orajige  and  grapa- 
fruit  trees,  w.3  would  undoxibtedly  value  them  more  for  their  ;purely  or- 
namental effect  if  the-"-  were  not  so  coOTiion,   Where  they  must  be  grown 
in  tubs  and  kept  in  a  greenliouse  through  the  winter,  crajige  trees  are 
considered  very  attractive  ornrjnenta.1  trees,  A  well-grown  grapefruit 
tree  is  handsome  at  all  seasons,  biit  ecpecially  so  '"^hen  the  great  j'el- 
low  balls  of  fruit  are  hajiging  in  clusters  all  over  it  in  winter.  All 
of  these  citrus  trees  can  be  grown  throughout  nearly  the  whole  of  pc-jdn- 
sular  Florica,   They  are  fruits  which  had  their  ancestral  home  in  f-^i 
eastern  Asia,  but  the^"-  have  si-;r&ad  around  the  whole  world  in  the  sub- 
tro  -^ics. 


Of  even  ••idor  range  O-  distribution  in  Florida  is  the  loquat, 
Tf'hich  adc^s  the  ch?rni  of  brig'.it  yellow  clusters  of  fruit  end.  panicles 
of  fra^rp.nt,  though  not  strikin^-ly  IjeaTi.tiful,  white  flowers  to  the 
green  of  its  s'^-.Tnietrical  body  of  foliage.   It  attains  a  height  of  20 
feet  usually,  and  forms  a  conpact,  round-headed  tree.   The  large 
leaves  are  glossy,  dark-rreen  on  the  uppsr  side  and  covered  with  a 
brownish  felt  on  the  under  side,  and  form  a  dense  ma.ss  of  foliage  all 
the  year.   The  juicy  yellow  fruits,  of  the  size  of  sitiall  plums,  have  a 
very  pleasant  pcidity  added  to  their  sweetness,  and  so  are  especially 
tasteful  to  tourists  whose  Tialates  find  the  richly  sweet  tropical 
fruits  somewhat  cloying.   P1.3ssant  to  eat  out  of  hand,  loquats  make  a 
splendid  preserve  or  jelly.   JTor  the  lower  ha.lf  of  Florida.,  at  least, 
this  is  the  onlv  ver:"'  satisfactor'-  reoresentative  of  that  most  promi- 
nent family  in  northern  horticulture,  the  Ror,e  faiiiily,  to  which  the 
apples,  pears,  cherries,  peaches  and  plfJTiS  belong.   It  also  is  a.n  Asia- 
tic fru.it,  n.^tive  to  central-eastern  China  originally  and  cultivated 
for  centuries  in  China  and  Japan.   From  these  countries  we  have  im- 
ported several  choice  varieties,  while  others  hpve  oeen   developed  in 
recent  vears  by  a  California  horticulturist.   One  small  villag^e  in 
China  is  said  to  ha.ve  shipped  out  $20,000  worth  of  loruats  in  a  single 
/'•ear,  and  in  Japan  the  fruit  production  runs  aoove  a  million  dollars 
annually. 

Limited  to  t'^e  more  tropica.l  -eortions  of  Florida,  the  lower  coast- 
al areas  mostl^,  are  tv/o  handsome  trees  which  have  come  to  us  from  the 
far  East  Indies  —  the  rose-a.-ple  rr/-   the  jajAolan  (Jr-im'  bo  Ian'). 
Both  are  large  evergreen  trees  with  medium-sized, somewhat  leatherv, 
glossy  green  leaves  w":>ich  form  a  fairl^'-  co.n'oact  body  of  foliage.   The 
rose-a-pple  is  the  more  "ddely  grown  of  the  two,  bof"  in  this  state  and 
in  the  rest  of  the  world.   Besides  its  handsome  as-^:ct  it  is  rema.rk- 
ablc  for  its  fre.its  rnf  flo'-ers.   The  fruits  are  the  size  of  a  large 
round  plum,  li;;h-t  yelloi''  in  color,  and  have  a  firm  but  verv  tender 
flesh  perfumed  with  the  odor  of  rose-w,-,ter  a.id  slightly  sweet.   It  is 
used  to  give  an  pxoma  to  jellies.   The  flowers  \voul(5  be  rather  incon- 
s^iicuous  greenish-white  blooms  if  it  were  r..ot  for  the  great  number  and 
size  of  the  stamens.   These  stand  out  lihs  long  vellow  pins  filling  a 
pin  cushion,  or  like  a  yellow  po/Jion,  being  three  inches  a.cross  the 
stamen  cluster.  The  new  loaves  a.ppea,ring  in  srring  a.dd  the  lovely 
wine  color  of  their  flush  to  the  green  of  th._  older  leaves.   The 
flowers  of  t'^e  j^mbolan  c"o  not  have  such  a  showy  pir.-cushion  effect  as 
those  of  the  rose-a.-:!ple,  but  arc  attractive  white  buttons  on  the  da.rk 
green  coat  of  foliage,  while  the  fruits  are  like  sraaJl  deep-purple 
plums.  Th^y  a.rc  used  for  preserves  raid  jellies,  rather  than  to  eat 
out  of  hand. 

Of  th"  trees  which  combine  ornrinenta;.  fruit  '-'ith  attractive  fo- 
lia.ge  habit,  the  mangos  probably  ra^iil':  first.   For  handsom.;ness  of  fo- 
liage aspect  alone  a  fine  specimen  of  mango  hr.s  f^w  eqv.a.ls.   It  madcos 
a  sjnimetrical,  round-headed  tree  of  up  to  60  fact  in  height,  with 
glossy  slender  leaves  which  are  a  rose  r^^d  when  the-"-  first  a-opcar  in 
the  spring  and  rer-vain  a  d.ark  •;:reon  for  more  than  a  y^a^r.   In  such  fine 
varieties  as  thu  Hrden  and  Uulgoba,  the  pendant  clusters  of  brilliantly 
colored  frj.it  make  a  sight  not  soon  forgotten.  And  when  in  late  v;in- 
ter  the  whole  tree  is  nearly  covered  with  a  majitle  of  panicles  of  sme.ll 
T'oTlowish  flowers,  the  :Tiajigo  wotild  almost  seem  to  qixalify  for  a.  triple 


?,  also.  In  its  "oc-st  v"ri;.ti^n  t'.ic  ;ariii:7;o  is  O"  f.'^j:  the  finest  of  the 
strictl:!-  troricel  fruits,  hr.vinrj,  n   pleasant  r.rorna  <ind  a  delightful  sub- 
r.cid  otialit-'^  adcfcd  to  its  svTctncss.   It  is  to  the  tropics  v/hat  tho 
pcr.ch  is  to  the   to:.Tp3ratc  zon,;,  pjid  con  "og  gro'^n  in  Florida  as  far  north 
as  Mcrritt's  Island  on  the  oast  coast,  Bradenton  on  tho  wost  coast,  and 
Lal:c  Placid  in  tho  ccntar  of  the  state. 

Ihj   West  Indian  star-rpple  is  a  tree  of  sorne'vha.t  more  tropical  re- 
quirements than  the  i.iango,  hut  of  even  more  h-:autiful  foliage  as;ject. 
The  tree  itself  is  by  no  means  so  large  and  sto.tely,  but  the  leaves  are 
glossy  green  -above  and  a  lovcl^-  satiny  ;;oldcn-broivn  underneath.  So  rs 
tht;  leaves  dpnce  in  the  breeze,  they  ^lerin  like  burnished  copper  when- 
ever their  undersides  meet  the  sijnlight.  The  flo'v^rs  are  small  pud 
rather  inconspicuous,  but  tho  fruits  are  as  large  as  a  mcdiUiTi-sized 
apple  and  ma--  be  either  light  ,;'jrecn  or  bright  pur"plc.  Within  the 
fruit  is  a  rather  soft  vrhite  flesh  of  melting  sveetness.   When  the 
fruit  is  cat  across  the  middle,  it  riresents  much  the  same  a-ppearance 
as  an  '-ir^le,  r/ith  a  st^r-shai^ed  cl-uster  of  seeds  at  the  core,  and  hence 
the  name  "st.-'r-.'^-DPlc. "   Its  sister  s-^occics,  a  nftive  tree  in  southern 
Florida,  tplccs  its  nc'':nc  from  tho  v^r?;'"  similar  character  of  the  leaf 
undersides,  and  is  Inno-ai  as  the  "satin-leaf." 

Another  tree  'Tith  beautiful  fr\iit  and  handsome  foliage  is  the 
lychce  (li'chee).   It  is  -jrather  difficiilt  of  ci.iltiv.^tion,  althou-^  it 
is  ful"'.-^  as  h-'-rd-''  rs  the  m"n.~o,  '■nd  there  are  h^'-rdl^''  a  dozen  bearing 
trees  in  the  stntc.  But  it  is  -^  tree  '-'hich  -ell  repays  t're  troxible  of 
gro'"ing  it.  Lihe  tho  lociuat  and  the  citrus  fruits,  the  lychce  is  a 
gift  from  thj  Celestial  Smpire,  'fhcre  it  h^s  been  cherished  for  over 
2,000  -'•^ars  ."s  the  finest  of  all  fruits.   The  tree  is  sm^ll,  round- 
headed,  and.  comr)r.ct,  •■'■-th  glossy,  darh-.-^Tcen  foliage  of  sl'^nder,  rather 
drooping,  com-nound  leaves.  The  frxiit  is  bornL.  in  grap.j-lilcc  clusters, 
and  each  fruit  is  like  an  oval  red  strrVoerry,  ^vith  tough,  rous^iened 
skin.   Inside  is  -^  cle"r,  transli.iccnt  -.ralp  of  very  agree.ably  blended 
swectn.:ss  and  acidit"^-.   The  dried  fruits  constitute  the  v^ell-known 
"lychec  nuts"  of  Chinese  confectioner?''.  As  is  true  also  of  tho  m-ngo 
and  the  loquat,  it  is  neccssarj'-  to  have  grafted  trees  from  named  va.ric- 
ties  to  be  sure  of  fine  duality  fruit. 

Vfhile  the  akcc  fruit  is  usuj'.lly  ^aten  after  frying,  rather  than 
fresh,  and  p^'^rt.-;:cs  in  luanj-  respects  of  the  qualit-^  of  a  vegetable  ra- 
ther th-n  of  a  f-ru.it,  -'•ot  it  is  al'.7ays  classed  as  a  fruit.  And  as  such 
it  deserves  consi'-'",.- ration  among  those  fruit  trees  h-^^ving  attractive 
fruits.   It  is  a  plant  -'hich  criac   to  the  TTcst  Indies  r  century  and  a

distinctive  fruits.  These  are  bright-red  capsules  of  2  or  3  inches 
length,  borne  in  large  cliistv.rs,  and  the  open  hrbit  of  the  tree  serves 
to  mrke  them  tho  more  cons->icuous.  Wlacn  they  are  fully  nvt-oxe  the-' 
split  open  to  disclose  a  shining  vhite  pul-p  containing  large  blaclc 
seeds.  The  pulp  has  a  ver--  nut-like  flavor  '-'hs-::   friedi  in  butter.  The 
tree  is  decidedl"  tro'-ical  in  reauiremcnts,  abovit  like  the  star-apple,

of  the  srmt   fT.iily.  The  tree  hr.bit  is  tall  and  stately,  often  spread- 
ing out  into  -".  gropt  roxuidGcl  top  "but  rl"T."s  conrriact,  and  the  medium- 
sized  l';?5ves  are  a  desp,  ^-glossy  green.  Tho  "oro'Tn  fr^jlts  are  usually 
the  size  of  a  smnll  aTOle,  and  contain  several  seeds  of  medium  size 
imlDedded  in  n   li.^it-''oro'7n  flesh  vrhich  is  soft  and  s'Toet  and  is  slightly 
gritty,  li?^e  a  northern  pe.-'r.  On  the  Florida  Keys  the  "dill;''"  is  one 
of  the  fe'7  fruits  "fhich  grcv  satisfactorily,  and  it  is  highly  prized. 
The  mil;:y  juice  of  the  oarlc  forins  the  'br-sis  for  che'.7ing  giuii,  and  in 
Central  America  great  areas  of  sairodillas  are  tai^ped  for  the  chicle 
(chich'l)  to  supply  our  great  chewing  gujin  industry.  But  a.part  from 
either  the  fruit  or  the  chicle,  the  sapodilla  is  a  tree  '■'orthy  of 
planting  for  its  handsome  aspect.   It  is  unusually  free  from  either 
diseases  or  insect  pests. 

Another  ver-  sturdy  and  hcndsomo  tree  vhich  endures  no  touch  of 
frost  is  the  tamarind.  Slo'v  of  gro-^th,  like  the  sapodilla,  it  devel- 
ops at  length  into  a   ver^^  large,  compact,  round-headed,  tree.  The  fine- 
ly divided  foliage  is  a  light  green  shade  rnc,  peculiarly  heautiful.  In- 
digenous to  tropical  Africa  and  perhaps  to  soiithern  Asia,  it  has  "been 
cultivated  for  so  long  in  India  as  to  m?l":o  its  origin  \incertain.  It  is 
'•"ell  "-orthy  of  cultivation  for  its  heauty  of  ha'iit  alone,  hut  it  also 
has  valu.ahle  fru.its.   These  are  pods  of  U  to  3  inches  length  ajid  an 
inch  across.   This  tree  belongs  to  the  Pea  family,  rnd  'within  each 
bro-'n  -cod  is  a  th.itf-  bronn  paste  of  high  siigar  content  and  high  aci- 
rity.  A  deliciov.s  cooling  drinl",  lilze  limeade,  is  made  from  this  pulp 
in  the  '^est  Indies,  -.'hile  in  the  Orient  the  ta:Ti?.rind  is  valued  as  an 
ingredient  of  chutnics  and  curries.  Like  the  s-podilla,  ^-hose  range 
it  shares,  this  hrndsomo  tree  has  fc'  dis'ases  or  pests,  and  it  is 
ver-'-  resistent  to  storm  Trinds. 

The  Cattlcy  or  Stra-vberry  gaava  is  a  rather  small  tree,  rarely 
exceeding  20  feet,  -dth  ver"  attrrctive  glossy,  deep-green  leaves  rjid 
smooth  bro'vnish  branches.   It  is  native  to  Brazil,  but  nas  carried  to 
China  b^-  Portug-uese  traders  early  in  the  iSth  century.  And  thus  it 
became  lenc^n  at  first  to  Europe  as  a  Chinese  fruit.  There  pxb   both 
yello^T  and  red-fruited  varieties,  both  alike  being  highly  valued  for 
m--^lcing  jellies  cs  -'ell  as  for  eating  out  of  hand.  The  fruits  are  much 
the  size  of  plujTis.  The  tree  is  about  as  hardy  as  the  orange,  and  is 
rarely  attacked,  o:"   either  disca.ses  or  insects. 

A  handsome  fruit  tree  of  ver"'  narro'v  range  of  distribution  in 
Florida  is  the  jr-k  (j.-ck).  This  brother  of  the  fa;.ious- bread-fruit  is 
onl"'^  hard^'-  enough  to  grov;  '-here  the  sa-nodilla  and  trmarind  flourish, 
and  is  an  imr;>igrant  originrlly  from  t.ie  motuatains  of  southern  India. 
It  forms  oridbr  favorable  conditions  a  tall,  densc-foliaged  tree  of 
statel"  hahit.  The  fruits  are  ver^'-  unusual,  being  as  largo  as  a  foot- 
ball and  borne  directly  on  the  trunk  or  main  branches.  They  are  har:'!- 
ly  a  sufficient  reason  in  themselves  for  the  gro-/ing  of  this  tree,  e-o 
far  rs  frvit  eurlity  is  concerned,  but  t'leir  rjiusual  character  makei 
them  higkl"  interesting  and  the  tree  itself  is  a  decidedly  handsome 
one. 

Another  decidodl''  tro-eical  frv.it  tree,  -vhich  has  come  to  our 


-  5  - 


shores  from  the  ncr.rb"  West  I-ndiss,  is  the  Mar.iinee  Apple  or  marae:'-.  The 
large,  glossy  deep-green  loaves  aie  borne  on  a  verv  cor.Tpact  frair-ework, 
and  the  tree  ic  hp.ndr.omc  and  stately.  The  large  fruits,  lilie  huge  rus- 
setcd  per.chos,  have  a  flesh  v/hich  '■/hen  fully  mature  is  of  the  texture 
of  half-ripe  pi;achos.  The,"  are  valuxd  rather  for  use  in  preserves,  to 
'Thich  they  impart  an  apricot  flavor,  than  for  use  as  a  dessert  fruit. 

Closely  related  to  the  persimmon  is  a  h?ridsome  evergreen  tree  of 
mediuin  size,  the  "blck  sapote,  "/hich  had  its  origin  in  the  highlands 
of  southorn  Mexico.   Lil.e  so  many  of  the  tropical  fruit  trees,  it  has 
glossy,  somevhat  leath'^ry  leaves  of  medium  size.   The  fruits  are  as 
large  as  small  apples,  and  contain  a  soft  pulp  of  dark  chocolate  brovm 
V7hich  is  very  s-'/eet.  As  a  dessert  fruit  it  is  more  esteemed  in  Mexico 
thrji  in  this  country.   The  tree  is  ver'-'  tender  to  frost. 

The  Otfheite  (O-ta-hite')  -  gooseoerry  is  a  s;:ia.ll  tree,  native  to 
Madagascar  and  India,  Vnich  gro'vs  'veil  in  the  southern  half  of  the 
state.  This  haiif.some,  erect,  little  tree  has  its  leaves  ranged  in 
pairs  along  the  sides  of  small  branches,  so  that  they  aprcar  to  be 
large  com^ijound  leaves,  and  these  feathery  branches  stand  out  stiffly 
from  the  larger  braiiches,  giving  a  vcrj'-  characteristic  appearance  of 
conroactness  to  this  small,  rovmd-ton-^ed  tree.   The  sm.all  green  fruits, 
about  Pdi   inch  across,  are  ribbed,  and  they  have  a  quality  similar  to 
the  goose-beri-y,  so  that  they  make  good  jellies  and  jams. 

Summing  up,  -o  note  that  the  Icumquat,  tangerine,  loquat,  rose- 
ap-ple,  and  jambolan  are  of  ornrmiental  value  for  foliage,  fruit  and 
flo"'ers,  all  three;  the  ma.ngo,  lycheo  and  star-apple  combine  colorful 
fruits  •-'ith  handsome  foliage;  and  the  sapodilla,  tajxirind,  jak,  niamey, 
black  sapote,  cattley  guava  and  Otaheite  gooseberry  are  valued  for 
fine  foliage  and  tree  habit.   And  these  are  only  those  of  Florida's 
fruits  v.'hich  have  ornamiental  value  a.s  trees  apart  from  the  value  of 
their  fruits  in  themselves.

ROSE  VAaiZTIES  POH  FLORIDA 


K.  Harold  Huxne ,  Assistant  Directoi',  Research 
Florida  Experirntnt  Station. 

TiThat  roses  shall  I  plant?  is  a  direct  auestion  that  must  he  answered  in 
some  fashion  hy  everyone  malting  a  rose  planting  or  setting  out  onlj'-  a  feiv  bushe^: 
in  the  garden.   And  the  answer  to  tie  question,  whether  that  ansv/er  '.'e-  dependable 
or  not,  inay  be  obtained  from  various  sources.   It  ina.v  be  had  from  rose  catalogiies 
that  are  today,  in  man.y  cases,  veritable  works  of  art,  Roses  in  these  booklets 
are  displayed  singly,  in  beds,  in  groups,  on  arhors  or  pillars,  in  color  and  in 
black  and  white.  Wlio,  having  seen  these  catalOtT'.es,  does  not  wish  to  plant  a 
rose  or  a  dozen?  The  text  goes  with  the  pi.-jtures;  it  niatches  them  in  flowexy  Ir.-.- 
guage  and  the  story  of  the  rose  and  its  behavior  is  complete.  And  so,  huiiting 
through  the  pages  of  the  catalogue,  there  coi'.^s  into  -"cistence  a  mental  rose 
garden,  the  bushes  in  vigorous  growth,  the  Leaves  healtliy,  green  and  lush,  T^ith 
flowers  in  gorgeous  h.ues  of  p.iuk,  or  red,  or  copper,  or  yellow,  or  glisteni?-ig 
white.  Thus  in  the  cool  o.V  a  v.intcr's  ni,;^ht,  by  wandering  through  a  ca.talogue, 
the  answer  is  fourd  to  f   qv  ,st..on,  "''inif  t  ross  shal]  I  plant?" 

But  the  catalogues  do  not  t.^11  all  fi.:  stoi,;;  the-"-  do  not  give  a  conrplete 
answer  to  the  question,  "Wiat  roses  shall  I  plant?"  The  descriptions  give  cer- 
tain information;  fhey   tell  certain  things  about  the  varieties,  their  good 
points  are  set  forth,  but  as  a  ge.ieral  rulo  the  rose  planter  must  learn  their 
shortcomings  and  deficiencies  for  himself.  This  i'^  where  the  catalogues  fail. 

Certainly  it  is  a  safe  conclusion  t.iat  all  the  varieties  listed  are  not  a- 
dapted  to  Florida  conditions,  Fuy  arj  they  not  adapted?  To  begin  with,  a  lot 
of  rose  varieties  named  and  introduced,  originated  in  different  parts  of  the 
world,  never  should  have  been  introduced  an^-v/aj''.  They  have  nothing  of  particu- 
lar value  to  recommend  them,   I  know  t^ere  is  a  constaait  tendency  on  the  part 
of  plant  lovers  to  interest  themselves  in  -^lants  that  are  new;  they  want  the 
very  latest  thing  and  the  rose  ori-'^;inators,  introducers  aiid  nurserymen  have 
xound  it  to  their  advantage  to  catir  to  the  desire  lor  the  nev?,  even  to  the  ex- 
jont  of  displacing  better  pl?nts.   In  conser-uence  there  has  sv/ept  over  tlxis 
country  a  wave  of  rose  sirj^er-sales....  nship  in  the  proinotion  of  varieties  that  is 
-lot   based  on  actual  performajice,  an^  this,  unfortunately,  is  resulting  and  can 
hut  result  in  a  deplorable  situation,  a  loss  of  interest  in  the  rose  on  the  pa^'t 
-."?  those  who  grow  it.  They  have  becxi  fooled  too  of  tan.  To  be  plain  and  candid 
ciL'out  it,  I  have  never  been  able  to  understand  "vhy  a  perfectly  fine,  v/ell-adapt- 
ed  old  rose  should  be  displaced  by  one  of  ;-orfc  r;.c-mt  origin  for  no  butter  rea- 
son than  that  it  is  new.  I  believe  in  new  roses;  I  believe  in  testing  them,  iu 
trying  thora  out,  but  for  mc  they  must  equal  in  all  particulars  those  I  have  and 
present  some  additionaJ  point  of  merit  before  I  discard  the  old,  dependable 
■  :orts.   I  believe  in  new  roses,  but  v/e  must  not  mal:e  gardens  with  them  or  buy 
them  in  quantity  unt:.l  thoy  have  been  tried  ai^d  found  satisfactory  for  our  area.

Hoses  of  today  are  of  very  ndxcd  parentages.  Hybridizers  have  "bred  roses 
of  in?.ny  ^linds  and  from  them  evolved  our  gard.en  forms.  Some  of  these  parents 
give  plants  adapted  to  our  conditions,  others  do  not.   If  into  the  makeup  of  a 
rose  there  enters  too  miich  of  an  original  svecies  that  "belongs  to  a  dry  climate, 
we  are  likel^'-  to  fail  wit'i  it  "because  our  rainfall  of  55  inches  or  so  annually 
is  entirely  different  fro  a  thr.t  to  w'^ich  it  is  adapted  or  to  which  one  or  more 
of  its  parents  has  "been  accustomed.  Heat  and  moisture  induce  poor  growth  in 
the  stunner  season;  diseases  lay  hold  of  stems  and  leaves,  and,  to  use  a  good 
Florida  expression,  "it  just  peters  out."  Furthermore,  roses  that  go  ba.ck  to 
parents  from  cold  clims.tes  are  likely  to  "be  failures.   They  will  not  succeed  un- 
less they  are  well  chilled  in  winter.  Occasionplly  follov/ing  a  cool  winter  thcj'- 
may  flower,  "but  that  is  not  often.  And  so,  though  they  may  "be  grown  into  good 
stout  plants,  they  do  not  bloom.  They  are  failures  for  just  the  same  reason 
that  plxims,  raspberries,  currants,  horseradish  and  other  plants  from  northern 
climates  are  failures  here.  We  have  succeeded  very  well  in  keeping  growing 
roses  and  other  plants  warm  by  biiilding  greenhouses  around  and  over  them,  but  re 
have  not  got  ver:':^  far  yet  with  refrigerating  them.  Some  varieties  of  roses  are 
notoriously  weaii  growers,  the  stems  are  slender  and  weak,  the  foliage  scant; 
thej^  haven't  enough  stamina  to  laroduce  buds  of  size  that  hold  up  their  heads. 
Away  with  theml 

The  first  requisite  of  any  rose  for  Florida  is  ability  to  grow  vigorously. 
They  may  malie  good  green  shrubs  if  nothing  more.  The  second  requisite  is  free- 
dom from  diseases  and  insects.  Wli;  ;:row  roses  to  feed  insects  and  harbor  di- 
seases if  they  alone  will  benefit?  And  the  third  desiderattim  is  free  flowering, 
—  an  abundant  harvest.  Whether  the  flowers  are  white,  pink,  copper,  red  or 
yellow  does  not  matter  if  they  are  not  produced  or  are  fev/  and  far  between. 
When  vigorous  growth,  freedom  from  disease  and  free  flowering  are  assured,  other 
things,  as  color,  shape  of  bud,  habit  of  growth,  can  be  considered. 

There  are  still  other  things  that  imist  be  considered  in  growing  roses  in 
Florida.   In  what  prrt  of  the  state  are  the;/-  to  be  grown  and  what  is  the  objec- 
tive? Our  state  is  of  vast  extent,  north  and  south,  east  and  west.   In  conse- 
quence the  climate  is  not  uniform.   It  is  wrirmer  in  the  southern  portions  in 
winter  than  in  the  north  and  west.  Roses  may  be  grown  and  flowered  out-of-doors 
all  winter  long  in  southern  Florida  or  in  favored  spots  elsewhere.  Seldom  do 
they  bloom  throughotxt  the  v/inter  in  northern  aid  northwestern  Florida.  Only  a 
very  few  times  have  I  kno^m  it  to  happen  in  the  last  thirty- five  years. 

Because  of  these  differences  in  climatic  conditions,  two  entirel;^  different 
systems  of  rose  growing  have  come  into  existence.   It  is  fort"UJiate  that  m£>.ny 
varieties  of- 'roses  begin  to  bloom  within  a  few  weeks  after  they  are  planted. 
Consequently  in  southern  rioricia,  in  addition  to  nal^:ing  gardens  v/ith  dependable 
varieties,  many  other  roses  cp.n  "be  pl.anted  in  autumn  on  heavily  fertilized  groimd 
and  treated  a.s  roses  are  in  northern  greenhouses.  Fine  flowers  are  produced. 
The  plants  cost  little  a.nd  in  spring  the  planting  is  abandoned  and  a  new  one 
made  the  following  autumn.  By  this  method  the  so-called  greenhouse  varietiu-?, 
for  the  most  part  not  adapted  to  all- the-year- round  conditions,  may  be  grovrn. 
The  plan  is  adapted  to  the  growing  of  fine  'cut  flowers,  but  only  by  the  stretch 
of  some  imagination  can  this  be  called  rose  gardening. 

In  the  colder  sections,  a  different  situation  is  presented.  Hoses  planteC. 
out-of-doors  in  auttimn  or  winter  do  not  bloom  until  spring  and  if  there  are  to 
be  roses  from  them  in  autumn,  the  other  good  flowering  season,  they  must  be  of 
such  constitution  as  to  pass  through  the  summer  in  good  condition.  Right  heie 
is  where  many  varieties  fail,  among  them  a  groat  many  of  the  newer  sorts,  par- 


ticalarlj-  those  crrrying  pernctif^na  (pcr-nee- she-ana)  strain  as  a  part  of  their

ill  rose  ^ardenin;^  in  this  str.to, 

A^r.in,  there  arc  diffcrercor,  in  :;oil  conditions  that  mast  bo  considered. 
One  set  is  roprescntcd  Id:/  the  flat'-'oods  of  northeastern  Florida,  another  ty  the 
lolling  clay  or  clay  underlain  soils  of  ncsttrn  Florida,  a  third  hy  the  sandy

Enough  has  "been  said  to  raa^-.o  ii^ain  the  fact  that  Florida  conditions  for 
rose  growing  r.re  not  uniform  for  tl;'-  state.   There  ajv  distinct  cliTir-.tic  a,nd 
soil  area.s  that  present  different  proolems.   It  is  true  that  soils  can  be  made 
and  draina-ge  in  some  measure  v/ill  trice  care  of  surplus  i/ater,  but  v/e  can't  do 
much  about  changing  climate  (ra.infall,  temperature  and  length  of  day),  and  our 
course  in  rose-grov/ing  lies  alon,^;  the  line  of  \ising  varieties  that  vdll  grow  in 
spite  of  it  or  because  of  it,  i';hic'':ever  'ray  ;'0U  lilcc  to  state  it. 

Thun  back  to  the  catalo.^e  again.   It  ■  ill  be  noted  tha.t  follo^ving  the  va- 
rieties certain  letters  hr  -e  been  nlaced:  T.  for  tea  roses,  H.  T.  for  h;^'-brid 
tea  varieties,  H.  P.  for  hybrid  r^erpetuals,  lois.  for  noisettes,  and  so  on. 
These  letters  indicate  f  I'i.ite  ^Toups  of  r'-'i-.s  of  kno'vn  origin.   They  are  at 
the  same  time  an  indication  of  I'O't  thoy  no  ir--.:ly  to  behave  in  a  given  loca- 
tion. The  roses  important  for  iis  are  to  be  foa.d,  for  the  most  part,  among  the 
Teas  and  Hybrid  Teas,  both  bushes  and  climbers.  To  these  may  be  added  Bengals, 
Noisettes  and  a  fe'v  others.   In  r.,cent  ••ea.rs  a  ntv;  strain  has  been  bred  into  our 
rose  varieties,  designated  by  the  name  Pernotiana.  One  of  the  regrettable  mis- 
takes that  has  happened  is  to  call  these  Hybrid  Teas.  True,  from  the  sta.ndpoim; 
of  their  breeding,  they  ma.;'  be  rightly  so  designated,  but  because  they  a.re  dis- 
tinctly different  in  their  behavior  from  the  old  t.^TDes  of  hybrid  teas,  thej' 
should  not  be  so  listed.  Better  to  call  them  Pernctia.na  or  Hybrid  Pernetiaiia 
roses.  Villc  de  Paris,  Los  Angeles,  Miss  Lolita  Armour  and  Talisman,  for  in- 
stance, belong  here.  The  only  satisfactory  results  likely  to  be  had  from  these 
sorts  is  in  growing  them  as  i7inter  roses. 

There  are  other  sources  from  which  informa.tion  on  rose  varieties  can  be 
secured,  but  one  more  only  can  be  mentioned.   In  nearly  every  corainanity  inhere 
are  individuaJs  Vno  ha.ve  tested  an'  ;-ro-7n  'lan;/  sorts.  Rose  growers  are  easy  to 
a.pproach  and  always  willing  to  help  others.   Consult  them,  see  T/hat  the^-  are 
growing,  find  out  vrhat  kinds  are  mi  t  c'^epnndable  —  then  go  back  to  youi'  own  gar- 
den and  plant  those  varieties.  Having  made  such  a  olanting,  add  to  it  a  few 
that  are  new  and  untried  sorts.  You.  will  add  a,  new  interest  to  your  rose  ven- 
tures and  increa.se  your  rose  knov/ledge. 

So  far,  I  have  dealt  with  fundainentals  only  that  we  may  have  a  better  un- 
derstanding of  some  of  our  rose  problems,  our  fadliii-  s  and  successes.  Now  for 
a  few  remarks  on  c?ch  of  several  varieties  t'lat  are  .lost  dependable,  rememberi'^g 
that  nev/  sorts  are  on  trial  that  a  rrxich  larger  number  ma^'  be  grown  far  south 
under  conditions  ap;'roxira~ting  those  of  greenhouses. 

If  I  were  to  make  a  rose  garden  in  Florida,  with  space  enough  at  my  dis- 
posal, these  varieties,  conr^idcriiig  the  f^uidaiventals  already  mentioned,  vrould  h^ 
my  choice: 


.^"T?,)IFp-  RIVOIPJl,  H.  T.,  has  a  cre?-nc'  white  flo'ver,  rose-pink  tinted  tov/ard  the 
center;  very  double.  A  vigorous  gr  .er  i'.'ith  clean  iolia.i<,e,    a  raolerate  producer. 
It  ran"-.s  as  a  good  garden  varict;"''  ar.d  the  flov.-ers  are  fine. 

DUCIIESSE  .OE  BRABMIT,  T,,  a  verjr  old  rose,  dating  f.'om  1357,  with  soft,  rosy- 
pink  flowers.  Vigorous  in  growth,  free  in  flo'.verin^^r-,  resistant  to  black  s^oot. 
This  was  President  Theodore  Roosevelt's  favorite  rose. 

ETOIIE  DE  HOLLA>IDE,  H.  T.,  originated  in  I5I9,  is  one  of  the  newer  roses.   A 
good  grower,  with  clean,  deep  green  leather?/  foliage,  color  a  dark  velvety  rose- 
red,  the  center  lichter.  Yevj   fragrant.  A  "jood  rose. 

FRANCIS  SCOTT  KEY,  H.  T.,  a  hybrid  of  Radiance,  v/ith  large,  rounded  crimson-red 
flowers,  is  often  a  satisfactory  variety  in  F]o'''ida.   It  is  a  vigorous  grower 
with  good  foliage. 

FRAU  KARL  DRUSCHKI,  H.  P.,  is  one  of  our  stron^^'ost  growers  and  when  its  large 
white  buds  and  open  flowers  are  secared  in  v2;ood  condition  they  are  very  lovely. 
However,  it  is  not  a  particularly  free  bloomer  and  in  spring  the  flowers  are 
likely  to  be  injured  by  thrips. 

FREIHERR  VOII  liARSCHALL,  T.  The  flowers  of  this  rose  are  a  dark,  carmine-red, 
and  the  young  shoots  in  their  coloring  almost  match  the  rose.   It  is  a  vigor- 
ous grower,  but  it  cannot  be  called  a  free  flowering  variety.   However,  I  have 
alwa,ys  esteemed  it  highly  and  grow  it  in  ra^r-   garden. 

S-^J,^?  A¥   TEPLITZ,  H.  T.  Few  roses  are  redder  than  this  and  none  sweeter  or  more 
intensely  scented.   It  is  a  vigorous  plant, very  resistant  to  disease;  the  fiov*-- 
ers  are  dark,  velvety  scarlet,  usually  borne  in  clusters.   It  is  very   prone  to 
produce  seeds  abundantly  and  the  hips  should  be  cut  off  to  prevent  weal-:ening 
the  plant.  The  climbing  varietur  i,'  also  ."'ood. 

KAISERIIC  AUGUSTE  VIKTORIA,  E.  T.   A  rose  of  moderrte  vi:;cr  n-ith  long,  pointed 
cream-'vhite  buds,  of  good  lasting  quolity.  TTiien  the  flowers  are  open  they  are 
almost  snov/y  white  with  a  slight  lemon  t:  it  at  the  center.  The  stems  are  ra- 
ther wealc.   It  is  a  moderate  gro.7er,  but  -Then  -/ell  fed  is  usually  satisfactory 
in  its  behavior. 

LOUIS  PHILIPPE,  Ben.   Perhaj^s  there  is  no  ..ore  comrr.on  or  widely  distributed 
rose  in  Florida  thm  this;  in  fact,  it  is  sciiietimes  called  the  Florida  rose.  It 
has  excellent  folipge;  it  never  seems  to  be  bothered  particularly  by  black  spot. 
The  flowers,  often  pro....  ced   in  clusters,  are  double,  rounded  or  somewhat  flat- 
tened, dark  red.   It  is  an  3::ccl'.ent  garl-n  o'lrib  and  dates  ba.ck  to  I83H,  so  it 
is  just  a  hTondred  years  old  t'.iis  year. 

MA1.U1T  COCHET,  T.  A  pink  rose  ".•ith  Ion'":,  poi  .ted  buds  and  large  flowers.  Palt. 
TDinlc,  deeper  in  the  center  and  light  yello'.v  colored  toward  the  base,  on  good 
strong  stems.  The  leaves  are  leather-'-  and  dark  green.  The  growth  is  vigorous 
but  rather  open  and  inclined  to  br-"nch  v.-idely.   It  does  not  flower  v/ith  parti- 
cular freedom,  but  the  blooms  are  ver:;  fine  when  secured  at  their  best.  Thei : 
is  a  white  variety  known  as  FKITS  UAI.IAIT  COCHET,  T.,  which,  in  all  respects,  i^: 
the  counterpart  of  the  pink  one  except  for  the  coloring  of  its  flowers,  v,'hich 
are  v.'hite,  t..:'.t.'.  red  on  the  outer  petals  and  pale  lemon  yellow  tov/ard  the  can- 
ter.

IlIvLil .  LAI/E6AED,  T.   This  is  another  of  the  old-time  roses,  stron~  gro'.ring  and  free 
frci  most  robe  diseases.   The  flo'vers  are  piiih,  rosy  salnon  at  the  conter.   It 
is  ver;-  dou-hle  and  blooiLS  free"'-:'. 

ilARIE  VAN  E0UTT3,  T.  Than  t'.jis  there  is  prohpoi.y  no  finer  rose  in  its  coloring. 
It  dates  back  to  IS7I.   I  have  seen  hushes  that  at  t-,velvo  years  of  age  trere  eight 
feet  high  ond.   eight  feet  across,  and  so  free  from  disease  ivas  the  foliage  that 
not  a  single  bit  of  black  spot  v^as  in  evidence.   The  flo'vers  are  pale  yellor;, 
large  and  very  double,  flushed  T^ith  caroine-pink  along  the  edges  and  lihely  to 
sho':/  more  pink  coloring  in  cool  -/eather.   It  is  a  very  satisfactory  bloomer  and 
a  rose  that  can  be  reconraended  unresorvodlj''. 

MIHITIS  FRAUCIS,  T.   In  habit  of  grov/th  this  rose  somewhat  resembles  Mme.  Lan>- 
bard,  but  in  petal  stj'-lc  it  is  quite  different.  The  petals  are  more  open  and  a 
beautiful  shade  of  pinl:.  The  foliage  is  healthy  and  the  bush  is  a  strong  grow- 
er. 

EAIUMCS,  H.  T.   Some  people  have  said  wo  have  tco  many  Radiance  roses  and  yet 
it  continues  to  be  one  of  the  roses  that  people  plant  because  it  is  easily  grov/n 
and  those  v.'ho  have  difficulty .  in  ha.i.clling  others  'onder  our  conditions  find  it 
very  satisfactory.  Probably  as  long  as  roses  are  gro'-vn  in  Florida,  Radiance 
roses  will  be  grovm.   It  is  vigorous,  produces  its  flov/^rs  on  good,  strong  stems, 
and  has  most  of  the  merits  that  a  ;,ood  rose  for  our  conditions  shoiold  have.   It 
is  frs^grant,  pinl:,  light  on  the  iiiner  surfcco  of  the  petals,  deeper  on  the  out- 
side, a  continuous  bloomer  during  the  growing  season  PJid.   regardless  of  the  opin- 
ion of  some  people  who  spealc  disparagingly  c"  its  merits  ajid  its  commonioess,  I 
would  recommend  it  for  a.v  and  ever'/  garden.   Its  co^mterpart  is 

RED  PJfflIA>TC3,  H.  T.  The  raiiie  style  of  bush,  the  same  style  of  flower,  but  dif- 
ferent in  color.  It  is  •"  clear  shade  of  cherry-red,  fine,  vigorous  and  depend- 
able. 

SAFRMO,  T.  The  buds  of  this  rose  are  unsurpassed.  Fnen  the  flowers  open  they 
are  only  partly  double,  salmon  in  color,  the  bush  is  vigorous  and  under  any  sort 
of  decent  conditions  long-lived.  An  ol:'.  and  very  dependable  varietur,  it  was 
originated  in  IS39. 

In  addition  to  these,  I  would  recommend  0PH3LIA  and  SUIIBURST  and  MARY 
COUIWSSS  OF  ILCHESTSR  for  further  trial. 

CLIIOING  ?.0S2S 

AK3M01E :  is  a  -oiiilc  Cherokee,  not  nearl;-  so  vigorous  in  its  growth  as  the  white 
form,  producing  its  lovely,  single,  pink  flowers  during  the  spring  months, 
^^losely  related  to  it  a.id  much  like  it  is  JL^ZiOVA,    darker  in  color,  so  that  'A 
is  sometimes  called  the  Red  Cherokee.  And  then  there  is  the  CHER0K3E  ROSE  ii- 
relf,  that  came  to  us  from  westerr  China  but  has  become  so  much  at  home  that 
It  is  often  regarded  as  a  native  A.  rican  plant.   The  white  form  is  a  rampant 
gro'ver  and  it  needs  a  lot  of  space  -.-here  it  can  clirb  high  into  the  tops  of 
trees  or  over  buildings,  but  it  is  well  '-'orth  having  'vherever  there  is  enovifVi 
space.  SILVER  MOON  is  a  Cherokee  hybrid,  glistening  white,  with  more  petals 
than  Cherokee.   It  is  a  very  strong  grower  that  apparently  has  given  a  good 
account  of  itself  in  northern  and  western  Florida.  The  11A.CART1IEY  ROSS  resej.i- 
bles  Cherokee  in  its  pure  "-hite,  single  flov/ers,  but  it  is  a  different  species 


(Eosa  "bractc!ata)and  tlie  foliar-^e  is  totally  'ajililce  that  of  the  Gherol:&c,   It  is 
iiatv.ra?^ized  in  different  parts  of  tlie  state  and  forms  dense  clur.rps  from  the  many 
shoots  thpt  come  up  from  the  ^'"rcxi.nd. 

3A1KSIA.   The  two  Banltsia  roses,  alha  (white)  and  lutea  (yellow),  are  "both  well 
v^orth  growing.  The  flowers  arc  smal],  and  clustered.  Perhaps  there  are  no  finer 
climbers  than  these  tv/o . 

BELLE  PORTUGUOISE.  A  strong,  rampant  growing  rose  that  must  have  plenty  of 
space.   It  was  probably  first  introfAiced  into  this  state  and  :;to7j\\   in  St.  jix\^s- 
tine,  ivhere  it  is  highly  esteemed.  The  buds  are  long  and  pointed,  the  flowers 
are  very  large,  sometimes  as  much  £3  six  inches  across,  partly  double,  flesh 
pinlc  in  color.  The  foliage  is  darh  green  and  glossy. 

CLIlvBIiMG  PERLE  DES  JARDINS,  CI.  This  is  one  of  the  best  of  the  yellow  rosss.  A 
climbing  sport  from  the  bush  form  of  the  snne  najne.   I  thinl;:  on  the  whole  it  is 
more  satisfactory  than  IIASECHAL  NIEL.   I  have  never  had  an;'  success  -./ith  the 
bush  form  of  this  name,  but  the  climbing  variety  is  a  most  satisfactory  rose. 

CLimiN&  PIIE  UMMl   COCKET,  CI.  T.  A  cotuiterpr.rt  of  the  bush  of  the  sane  name, 
but  a  strong,  vi.:;orous  cli  ..bing  rose. 

CLII'fflING  ROSE  liARIE,  H.  1.,    is  a  rose-pint  flowered  variety  with  good  foliage, 
vigorous  and  free-flowering, 

DEVONIENSIS,  CI.  T.  A  very  old  rose  (l?^+l),  ■uite  tinged  with  blush.  Very  vi- 
gorous, often  called  the  "HafTiolia  Rose." 

DR.  W.  VAN  FLEET,  H.  tV.,  is  a  strong  growing  climber  with  pale  pinli  or  almost 
white  buds.  There  are  fine  plants  of  this  in  northern  Florida,  perhaps  else- 
^'here . 

EORTUKE'S  YELLOW:  For  exquisite  coloring  in  shades  of  yellow,  gold  and  bronz, 
no  rose  surpasses  this.   It  is  a  moderate  climber  with  good  foliage;  the  flow- 
ers are  produced  abundantly  along  the  twigs.  Hov/ever,  it  is  only  in  bloom  for 
about  a  month  in  spring,  but  because  of  its  dainty  coloring  and  the  beauty  of 
its  half-double  flowers  it  merits  a  place  in  any  ro=e  garden. 

PAUL'S  SCARLET  CLIlvGSER  is  a  good  climbing  rose  with  deep,  dark,  rich  scarlet 
flowers.   It  is  a  moderate  grovrer. 

ESIME  I'AARIE  KSIJRIETTE,  CI.  H.  T.   A  vigorous  gro-'ing,  free  blooming,  climbing 
rose,  ^'ith  cherry-red  flowers.  Wlier.  given  proper  care  ''nd  attention  it  malres  a 
magnificent  plant.   It  is  inclined  to  lose  its  leaves  at  the  base  so  that  the 
branches  or  stems  are  bare,  and  t'lis  is  its  r.iain  draback. 

RE\'E  D'OR,  CI,  T.  This  rose  holds  its  folia;;e  well  do"'n  to  the  base  of  the 
plant,  deep  green,  vigorous  and  strong  growing.  The  flowers  are  almost  the 
counterpart  of  those  of  Safrano,  buff  yellow  or  srlmon  in  color.

SPILlYIiia  FOR  FLOVffiR  GAi?DEW  INSECTS 


A. 


11.   Tissot,  Associate  Entomologist, 
Florida  Experiment  Sta.tion 


Everyone  has  heard  the  expression,  "Ever;-  rose  has  its  thorn,"  but 
only  those  who  have  grown  a  flower  garden  know  hov»r  trxie  it  is  that  every  flower 
also  has  its  insects,  —  whole  sv.'arms  of  insects! 

During  recent  years  a  great  deal  of  attention  has  been  given  to  home 
"beaut if i cat ion  and  the  growing  of  all  kinds  of  flowers.   With  the  increase  of 
these  flowering  plants  tnere  has  come  a  corres  ;onding  increase  in  the  number  of 
insect  problems.  PerhaTDS  nothing  detracts  more  from  the  beauty  of  a  plant  or 
group  of  plants  than  to  have  the  leaves  or  flowers  ragged  and  half -eaten  by 
caterpillars  or  grasshoppers,  or  to  have  the  leaves  yello;ved  and  curled  from  the 
feeding  of  aphids  or  other  sucking  insects. 

Most  of  this  damage  can  be  prevented  by  tne  intelligent  use  of  the 
proper  insecticides,  \7ith  a  dozen  or  so  of  the  standard  proven  insecticides  to 
choose  from,  one  can  control  a.lmost  any  of  the  insect  pests  that  are  likely  to 
occur  in  a  flower  garden. 

For  convenience  we  may  divide  all  flower  garden  insects  into  two 
large  groups  according  to  their  method  of  feeding.  The  members  of  the  group 
which  we  call  the  biting  insects  have  well-developed  jaws  which  enable  them  to 
bite  off  and  eat  portions  of  plants.  Those  of  the  other  group  which  we  call  the 
sucking  insects  have  an  entirely  different  method  of  feeding.  These  insects 
have  a  sharp  tube-like  structure  which  they  tlirust  into  the  leaves  or  other  parts 
of  plants  and  through  which  they  suck  up  the  plant  sap  v.'hich  serves  as  their 
food.   It  is  very  important  that  v/e  know  to  vmich  group  an  insect  pest  belongs 
because  upon  this  fact  will  largely  depend  the  method  of  control  that  mrast  be 
used. 


The  insecticides  which  may  be  used  in  the  flower  garden  fall  into  two 
group's:   the  poisons  or  internal  insecticides  and  the  contacts  or  external  in- 
secticides.  In  general  the  poisons  are  used  for  controlling  insects  of  the  bit- 
ing type  while  the  contact  insecticides  are  used  against  the  sucking  insects. 

The  manner  in  v/hich  one  applies  an  insecticide  will  be  determined 
largely  by  the  nature  and  habits  of  the  insects  wliich  one  wishes  to  control  and 
by  the  available  equipment  for  applying  the  control.  For  example,  if  one  is 
troubled  by  caterpillars  which  bite  through  and  sat  the  entire  thickness  of 
leaves,  all  that  is  necessary  for  good  control  of  the  caterpillars  is  to  cover 
the  upper  surface  of  the  leaves  thinly  and  evenly  with  a  poisonovis  material. 
This  method  of  applying  the  poison  would,  hov.ever,  have  little  or  no  value  if 


^     O     — 


the  caterpillars  merely  skeletonized  tlie  leaves  by  eating  av/ay  the  lower  sur- 
face and  leaving  the  upper  surface  untouched.   In  a  case  of  this  kind  it  w-ouLd 
be  necessary  to  apply  the  poison  in  such  a  v/ay  that  the  lov»er  surface  of  the 
leaves  would  be  coated.   Suppose  that  vi/e  have  a  rose  bush  infested  with  aphids. 
These  are  s\icking  insects  which  feed  upon  the  sap  of  the  plant.  This  sap  is 
obtained  from  inside  the  plant,  being  sucked  up  thro\i.gh  a  fine  tube-like  struc- 
ture which  is  thrust  into  the  tissues  of  the  plant.   It  is  impossible  for  such 
'an  insect  to  take  up  and  s;vallow  a  material  which  covers  the  surface  of  the 
plant.  Here  v/e  imist  use  material  that  "./ill  cause  the  death  of  the  insect  v/hen 
it  comes  in  contact  with  its  body. 

The  most  satisfactory  and  widely  used  of  the  poison  insecticides  is 
arsenate  of  lead.  This  is  sold  in  the  form  of  a  thick  paste  or  as  a  v/hite  pow- 
der that  somewhat  resembles  flour.  The  pov/der  form  is  generally  considered 
more  desir-able  and  is  the  form  usually  carried  in  stock  by  insecticide  dealers. 
Arsenate  of  lead  may  be  mixed  with  water  and  used  as  a  liquid  spray  or  it  may 
be  used  in  the  form  of  a  dust .  When  used  in  water  the  usual  dosage  is  one  ounce 
of  the  powder  to  three  gallono  of  water.   To  prevent  buj-ning  of  the  plants  one 
ounce  of  hydrate d  lime  should  be  added  to  e ach  gallon  of  the  spray  solution. 
Arsenate  of  lead  can  also  be  combined  with  some  inert  powder  such  as  hydrated 
lime,  fullers  earth,  talc,  or  low  grade  flour  and  used  as  a  dust.   The  propor- 
tion which  has  proven  most  generally  satisfactory  is  one  part  of  the  lead  ar- 
senate powder  to  six  or  eight  parts  of  the  lime  or  other  dilutent.  These  pro- 
portions are  by  -weight  and  not  by  measure  as  different  brands  of  lead  arsenate 
may  vary  greatly  in  texture,  some  being  light  and  fluffy  while  others  are  much 
heavier  and  more  compact.  Those  who  object  to  the  white  residue  left  on  the 
plants  by  these  sprays  and  dusts  can  obtain  a  green  arsenate  of  lead  that  is  ful- 
ly as  effective  as  an  insecticide  and  whose  residue  is  scarcely  noticeable  on  the 
foliage. 

The  fluorides  and  f luosilicates  foi-m  smother  group  of  insecticides 
which  can  be  used  for  the  control  of  biting  insects.  These  also  leave  a  white 
residue  on  the  treated  plants  and  they  have  few  advantages  over  arsenate  of  lead 
but  can  be  used  as  a  substitute  for  the  latter  if  it  cemnot  readily  be  obtained. 

The  gardener  has  a  large  array  of  different  brands  from  which  to 
choose  when  he  b-uys  a  contact  insecticide  for  use  against  sucking  insects.  The 
majority  of  the  satisfactory  contact  insecticides  are  plant  derivatives,  the 
active  killing  agents  being  extracts  or  compotinds  made  from  certain  kinds  of 
plants.   One  of  the  oldest  of  tne  contact  insecticides  and  one  v;hich  still  is 
used  very  extensively  is  nicotine.  All  tobacco  contains  nicotine  in  a  greater 
or  lesser  amount  and  finely  ground  tobacco  is  sometimes  used  as  a  contact  in- 
secticide.  In  a  few  special  cases  it  may  prove  effective,  but  in  most  cases 
the  nicotine  is  given  off  so  slowly  that  the  insects  will  not  be  killed.   It  is 
usually  more  desirable  to  erai^loy  one  of  the  commercial  nicotine  preparations. 
Nicotine  sulfate  is  the  form  v/hich  is  most  generally  available  but  there  also 
is  on  the  market  a  solution  of  pure  nicotine.  The  most  common  brand  of  nicotine 
sulfate  and  one  which  can  be  obtained  most  anj^vhere  is  knowTi  as"Black  Leaf  ^0." 
This  is  a  black  liquid  which  as  tne  name  implies  contains  forty  percent  of  nico- 
tine. Nicotine  sulfate  can  be  mixed  with  water  and  used  as  a  liquid  spray  or 
it  may  be  combined  with  a  powder  of  some  sort  and  applied  as  a  dust.  For  use 
against  aphids  and  some  other  soft-bodied  insects  nicotine  sulfate  is  used  at 
the  rate  of  one  and  one -half  teaspoonful  to  one  gallon  of  water.  For  more  re- 
sistant insects  more  of  the  nicotine  must  be  used.  When  nicotine  sulfate  is 
used  alone  in  -water,  tlie  spray  tends  to  collect  in  large  drops  and  runs  off  the

plants.  To  counteract  this  tendency  a  small  amount  of  soap  or  other  spreader  is 
usually  added  to  the  spray  solution.  These  substances  cause  the  spray  to  spread 
evenly  in  a  thin  film  over  the  surface  of  the  plants  and  the  "bodies  of  the  in- 
sects. 

Another  group  of  contact  insecticides  is  composed  of  extracts  or 
compounds  of  pyrethrum  and  of  certain  leguminous  plants.  Pyrethrum  powder  has 
long  heen  used  as  a  household  insecticide  sold  under  the  name  of  Persian  or 
Dalmatian  insect  powder.   This  powder  is  not  so  satisfactory  for  outdoor  use 
against  insects  on  plants  but  some  of  the  prepared  pyrethrmn  sprays  have  proven 
very  effective  for  this  purpose.  There  are  a  number  of  different  insecticides 
containing  preparations  of  rotenone.  Rotenone  is  the  active  insect  killing  a- 
gent  in  the  plants  knovm  as  derris  and  cub6.  The  nyrethrrum  and  rotenone  sprays 
are  effective  against  the  same  tj.-pe  of  insects  that  are  controlled  with  nico- 
tine and  they  have  a  certain  advantage  over  nicotine  in  that  they  will  also 
kill  some  of  the  larger  and  more  resistant  insects  that  cannot  be  controlled 
with  nicotine.   Some  of  the  easily  procured  pyrethrum  sprays  are:   "Evergreen," 
"Red  Arrow,"  "Kaloil,"  and  "Agripa^:."  Rotenone  is  the  active  agent  in  the 
sprays  "Derrisol''  and  "Cubor."  An  insecticide  called  "Florote"  contains  both 
pyrethrum  and  rotenone. 

There  is  another  group  of  contact  inp;ectiddes  which  may  be  mentioned 
though  thoir  u.se  in  t.ie  flo./er  garden  will  be  rather  limited.  These  are  the 
oil  emulsion  sprays.  They  are  iiseful  mainly  as  a  control  for  white  flies  and 
scale  insects  v;hich  sometimes  attack  roses  and  other  woody  ornamental  plants. 

Fnether  one  snail  put  on  a  liquid  spray  or  a  dust  will  depend  upon 
the  available  equijiment  and  to  some  extant  on  weai-he:'  conditions.  A  dust 
treatment  can  be  applied  more  qxiickly  than  can  a  sp.raj.  .   On  the  other  hand 
plants  can  be  dusted  only  when  the  air  is  perfacLly  still  v/hile  sprays  can  be 
put  on  even  though  there  be  considerable  breeze  blowing.   To  properly  apply 
the  liquid  sprays  one  nmst  have  a  sprayer  of  some  sort.   If  one  has  only  a  few 
plants  it  ma.y  be  possible  to  get  along  with  a  small  sprayer  or  atomizer  such  as 
is  commonly  used  for  applying  fly  and  mosquito  sprays.   If  one  has  a  fair-sized 
garden  3.t  will  perhaps  be  advisable  to  get  a  compressed  air  or  knapsack  sprayer 
having  a  capacity  of  two  or  three  gallons.   The  batter  sprayers  of  this  type 
having  a  copper  tark  will  D.aet  longer,  but  the  less  exir^ensive  ones  with  a  gal- 
vanized iron  tank  will  apply  the  insecticide  jur.t  as  effectively  and  will  last 
for  a  number  of  years  if  carefully  washed  and  dried  e'JTter  using. 

There  are  two  comm.on  types  of  small  hand  dusters  v/hich  are  suitable 
for  use  in  the  flower  garden.   In  one  type  the  dust  is  blo-.7n  out  and  distri- 
buted by  a  bellows  arrangement  -./hile  tne  other  type  operates  somewhat  like  a 
tire  pump.  With  sucn  a  duster  the  dry  insect luiie  can  be   applied  thinly  and 
evenly  and  it  can  be  blown  in  any  direction  so  uhat  the  undersides  of  the  leaves 
can  be  protected  as  vvell  as  th-  upper.   If  one  has  neither  a  sprayer  nor  a  dust- 
er dry  insecticides  can  be  applied  by  placing  tne  material  in  a  cloth  bag  and 
shaking  this  above  the  plants.  One  objection  to  this  method  is  that  the  powder 
is  applied  very  unevenly  so  that  some  parts  of  the  plants  will  have  entirely 
too  much  v/hile  other  portions  will  be  wholly  unprotected.   Then,  too,  this  me- 
thod allows  the  insecticide  to  be  applied  to  only  tne  upper  s^'orface  of  the 
leaves  and  is  practically  uselt^ss  against  insects  that  feed  only  on  the  lower 
surface  of  the  leaves. 

There  are  a  great  many  different  kinds  of  insects  that  may  and  fre- 
quently do  become  troublesome  in  the  flower  garden,  and  no  attempt  v/ill  be  made 
to  enumerate  all  of  them.   It  may,  hov/ever,  be  ;vell  to  mention  some  of  the  more 
common  pests  and  briefly  consider  the  easiest  methods  of  controlling  them. 


-  I;  - 

The  caterpillars  •.vhicli  are  the  yourig  or  larvae  of  the  moths  and  but- 
terflies constitute  cne  of  tixe  important  groups  of  tne  biting  insects.   In  gen- 
eral they  can  be  controlled  by  covering  the  plants  with  a  spray  or  dust  of  ar- 
senate of  lead.  The  yc-onger  stages  of  many  of  the  caterpillars  can  also  be  con- 
trolled effectively  by  the  use   of  one  of  the  pyrethruin  or  rotenone  sprays. 

Some  of  the  beetles,  notably  the  flea  beetles,  sometimes  become  in- 
jurious in  flower  gardens .  The  treatment  prescribed  for  the  caterpillars  v/ill 
also  prove  effective  against  nost  of  these. 

Cutworms,  mole  crickets,  and  grasshoppers  cannot  successfully  be  con- 
trolled with  either  sprays  cr  dusts.  The  best  method  of  dealing  with  these  pests 
is  to  feed  them  a  poisoned  bait.  A  very ' satisfactory  bait  is  made  by  thoroughly 
mixing  four  ounces  of  par is  green  with  six  pounds  of  bran.  This  mixture  is  next 
moistened  with  water  to  vriiich  has  been  added  a  little  syrup  and  the  juice  and 
grated  rind  of  an  orange  or  lemon.  This  bait  is  best  applied  late  in  the  even- 
ing and  may  be  sown  broadcast  v/iiere  the  pests  are  found  or  it  may  be  scattered 
thinly  along  the  rows  of  plants. 

The  aphids  or  plant  lice  mal:e  up  a  group  of  the  sucking  insects  that 
is  often  troublesome  in  flower  gardens,  almost  all  kinds  of  plants  being  subject 
to  attack.  Aphids  ntultipli'  very  rapidly  and  the  main  requisite  for  successful 
control  is  that  the  treatment  be  applied  at  their  first  appearance  before  the 
infestation  becomes  too  general.  Leafhoppers,  plant  bugs  and  fleahoppers  are 
other  sucking  insects  that  may  attack  cur  garden  flowers.  Thrips  form  still  an- 
other group  of  the  sucking  insects.  They  are  very  small,  yellow,  brown,  or 
black  insects  that  are  commonly  found  in  flov/ers  but  which  occasionally  injure 
other  parts  of  plants.  Their  small  size  enables  tnem  to  go  into  the  depths  of 
flov/ers  where  they  are  protected  and  it  is  difficult  to  reach  them  with  a  spray 
material.  The  various  sucking  insects  are  controlled  by  the  use  of  nicotine 
sulfate  spray  or  dust  or  with  one  of  the  pyrethrum  or  rotenone  sprays.   Some  of 
these  insects  are  more  resistant  tnan  others  and  a  stronger  spray  must  be  used 
to  kill  them.  The  manufacturers  of  insecticides  give  directions  for  mixing 
their  sprays  for  use  against  different  kinds  of  insects  and  these  should  be  fol- 
lowed for  the  particular  insects  in  question. 

The  essential  elements  in  the  control  of  insect  pests  of  the  flov/er 
garden  can  be  summed  up  in  one  sentence.  Keep  a  close  v/atch  of  the  plants  and 
detect  the  first  appearance  of  the  pest,  determine  if  it  is  a  biting  or  sucking 
insect  and  on  what  part  of  tne  plant  it  is  feeding  and,  having  learned  these 
facts,  apply  a  suitable  insecticide.

DISEASES  OF  THE  FI.OTOR  GARDEIT 


Talk  llo.  22 
Fetruarj'  7,  193^+ 


By   Georf^e  F.  ?Jeber,  Plant  Pathologist 
Florida  Agricultural  E:cperiment  Station 

"Oh,  Daddy,  can  you  come  out  in  the  j^nrden?  There  is  something  real  ira- 
portavit  about  the  flowers,"  thus  shouted  ten-year-old  Joan  shortly  after  re- 
turning from  Sunday  School. 

Doctor  Allen,  a  distinguished  physician,  slowly  laid  down  his  widespread 
paper  and  moved  from  the  upholster-..,;,  chair  to  the  garden. 

"See,"  said  Joan,  "the  lilies  are  ?11  dying  and  do  you  remember  what  you 
told  me  yesterday  about  ther^?  You  said,  'Consider  the  lilies  of  the  field,  . 
they  toil  not,  neither  do  they  sxdn  and  jut  I  say  unto  you  that  even  Solomon 
in  all  his  glory  was  net  arrayed  lil;e  oae  of  these.'   I  didn't  understand  all 
about  it  but  these  sick  ones  don't  loolu  th?t  yray." 

"Well,  my  child,  it  loolcs  as  though  some  of  our  lily  plants  are  sick." 

"Daddy,  can  you  't^^d  to  tliem  and  get  them  well?"  asked  Joan. 

"I'm  afraid  not,  but  you  l.row  we  have  sc:,.c  plant  doctors  in  Gainesville. 
Suppose  we  send  some  of  the  sick  plants  to  them  and  find  out  the  trouble." 

As  Dr.  Allen  sought  a  trowel,  little  ooan  hurried  to  join  some  playmates 
in  a  neighbor's  yard.   As  the  lilies  were  b:ing  dug,  many  thoughts  were  going 
through  the  active  brain  of  Dr.  Allen.  Ke  knew  that  the  flowers,  leaves,  stem, 
and  roots  v/ere  necessary  for  accurate  dir^nosis.  And,  when  sending  these, 
thought  he,  why  not  send  along  a  few  of  the  mildewed  zinnia  leaves?  He  shook 
the  dirt  from  the  lily  roots  rjid  wrapped  them  in  paper.   "I'll  also  send  some 
Agcratum  leaves  that  are  yellowing  and  show  yellow  spots,  Djid  these  petunia 
flowers  that  are  st^anted  and  mottled."  After  half  an  hour,  a  number  of  diseases 
plants,  spotted  leaves  and  mp.lformed  flowers  wore  carefully  packed  for  shipment 
to  the  Plant  Pathologist  at  Gainesville.   Tlioiigli  mate,  Dr.  Allen's  mind  was 
functioning  as  follows  as  he  laistircly  surveyed  his  floT.^er  g-''rd':^n  and  porr^'-T'''' 
plantings:   "Flowers,  of  all  created  thin.-^js,  arc  the  most  innocently  simple, 
the  most  superbly  complex  playthiings  for  children,  soothers  of  hviman  sorrow, 
ornaments  of  the  feast  and  companion'^,  of  the  corpse,  beloved  by  the  idiot  and 
studied  by  the  thinking  scientist.  Yet  '-.'hen  they  get  some  disease,  it's  a  d:.f- 
ferent  story." 

The  specimens  and  letter  were  duly  r.^ccivod  at  the  Experiment  Station,  a- 
long  with  others  from  va.rious  prrts  of  Florida.   The  plant  pathologist  worked 
over  the  morning's  mail;  ho  examined  the  specimens,  with  eaii.  without  the  aid

inde'^vor  ?n  which  both  sexes  and  all  degrees  of  education  and  refinement  unite. 
!K'o  one  is  too  polished  to  sec  the  be-^uty  of  flowers,  nor  too  rough  to  be  capable 
of  enjoying  them.   It  attracts  and  c'olights  all.   It  seems  to  be  a  common  field 
'.vhere  evciy  degree  of  taste  and  refinement  mr.j'-  unite  and  find  opport^'onities  for 
their  gratification. 

A  day  or  t^70  l^.ter,  Dr.  Allen  rc-ceived  tho  following  reply  to  his  lett^ir: 

"Dear  Mr.  Allen:  Your  letter  "  ^d  sp.-icimcns  have  been  received  "Jid  I  shall 
hero  attempt  to  give  you  definite  iiiform-.tion  concerning  the  questions  asked  rjid 
a  diagnosis  of  the  troubles  on  the  specimens  you  sent  in. 

"Your  question  asking  what  mosaic  is,  is  'veil  demonstrated  by  tho  easter 
lily  and  petunia  specimens  which  you  sent  in  to  us.   They  have  the  disease,  and 
all  Tjl^nts  in  your  garden  showing  these  symptoms  should  be  carefully  removed  and 
destroyed  because  the  disease  is  contragious  •"nd  will  spread  to  healthy  plants. 
Mosaic  is  the  name  rpplicd  to  this  disease  of  plants  the  symptoms  of  which  are 
green  and  yellow  mottled,  "tuntcd,  malformed  leaves.  The  entire  plants  are  u- 
sually  stunted,  causing  t"  e  p].rnt  to  app  ^ij-  more  rosetted  than  healthy.  No  para- 
site has  been  fouiid  rosio.isiblo  for  tho  dis:.asc,  but  there  is  something  con- 
tained in  the  sap  of  mos^dc  pl-'^iits  th^t  cTses  the  disease  in  health;/  plants, 
v/hen  sap  from  a  diseased  plant  is  transferred  to  a  healthy  one.   This  'something' 
is  known  in  plant  science  as  a  virus  and  mo-^f^ic  is  often  referred  to  as  a  'virus 
disea-se.  '   Sucking  insects  such  as  aphids,  jrssids,  etc.,  are  probably  more  re- 
sponsible for  its  spread  than  a-^vthing  elne  and  it  can  be  quite  well  controlled 
by  controlling  them.  Fungicides  are  of  no  value  in  its  control  -and  mosaic 
plants  should  be  removed  because  they  cannot  be  cured.  Press  Bulletins  from 
the  Experiment  Station  dealing  with  this  trouble  will  give  you  further  details. 

"The  leaf  spots  of  marigold  and  phlox  are  caused  by  certain  prrasitic  fun- 
gi.  The  one  on  rnr.rigolds  is  not  comiAonly  found,  while  the  one  on  phlox  is  foujii 
annually.  Both  are  severe,  however,  and  can  be  satisfactorily  controlled  by  a 
liquid  U-U-^O  Bordea-ux  spray  or  by  dustinj;  with  20-80  copper-lime  dust.   These 
•'■"un -•:  c i r" e s  should  bo  applied  often  enough  to  keep  all  nev7  growth  covered  and 
protected. 

"The  zinnia  leaves  showing  th.':  white  powdery  substoxicc  on  the  s'vu-face  have 
a  disease  loiown  as  powdery  mildew  r    \   those  with  the  scattered  small  angular 
spots  with  dark  rcddish-brov/n  to  pm-ple  borders  have  a  lorfspot  disease  caused 
by  another  fungus.   The  powdery  mildew  can  be  controlled  by  dusting  the  plants 
with  finely  grou:id  sulphur  applied  when  the  plants  are  ':.'et  with  dew.  Applica- 
tions should  be  made  often  enough  to  keep  the  mildew  chocked.   The  leaf spot 
is  controlled  by  .-applying  bordeaux  or  coopor-lime  dust,  the  spray  v;hen  the 
plants  are  dry  rnd  the  dust  when  they  are  web.   If  both  diseases  appear  on  the 
plants  at  the  s'\m.e  time  a  single  liquid  spr,":'  of  lime-sulphur  is  probably  most 
effective.  Don't  ti^r  to  combine  bordeaux  and  sixlphur;  they  v;ill  not  mix  well. 

"The  agerattim  loaves  showing  sma.ll  circular  yellow  spots  with  brown  cen- 
ters, have  a  disease  knc  m  as  rust.   This  is  a  true  rust  caused  by  a  specific 
fungus  and  has  no  relationship  to  the  term  'rust'  erroneously  applied  to  va- 
rious diseases  such  as  milde-J,  anthracnosc  ?-:d  blights.   The  spotted  ageratum

'iho  infection  is  general,  cut  back  all  plr.nts  to  three-inch  stubs,  roracve  the 
leaves  on  the  stubs  and  then  dust  heavily  the  surrounding  soil  surface,  lifter 
the  tops  are  removed  and  destroyed,  -ith  fine  sulphur. 

"The  rose  loaves  show  blacl:  spot  and  I  might  add  th-^t  finely  ground  sul- 
phur is  the  best  fungicide  to  apply  to  control  this  disease  v;hich  is  so  common 
^ver;"7hc-re.   The  sulphur  should  be  fine-  eroi:igh  to  ro   through  a  3OO  mesh  sio-ve. 
The  lilies,  African  daisy  and  coreopsis  plants  are  being  killed  by  the  c oranon, 
soil  inhabiting  fungus,  Sclorotiurn  rolf sii.  The  fungus  is  common  and  destrac- 
tive  and  nothing  can  prevent  a  plant  d.ying  that  shov/s  the  '.7ilt  symptom  of  the 
disease.   You  should  carefullj'-  remove  those  plants  and  the  soil  immediately 
currounding  them  with  a  shovel;  be  careful  not  to  scatter  the  small,  brovm, 
round  sclorotia  that  appear  in  numbers  a,round  the  base  of  the  stem,  because 
they  propagate  the  fungus  that  causes  this  disease. 

"As  to  hollyhocks,  they  do  not  do  '•■ell  in  this  part  of  Florida  because 
soil  fungi  attack  them  during  their  resting  period  —  you  knov;,  these  plants 
are  biennials  —  and  kill  them  or  v^e.-'ken  them  so  thrt  they  do  not  do  well  the 
second  year.  Many  other  biennials  and  perennials  are  affected  in  this  same 
way» 

"Many  garden  diseases  are  cr'rricd  over  in  the  soil.   To  control  them  the 
soil  should  be  sterilized.   This  is  best  rccori.plished  by  using  a  formaldehyde 
solution  prepared  by  diluting  one  gallon  of  coimiiercial  formaldehyde  in  fifty 
gallons  of  water.   After  being  thoroughly  mi-  d,  tlie  solution  is  ready  for  ap- 
plication for  v/hich  use  a  garden  sprinleling  can  is  very  handy.   The  soil  to  be 
treated  should  be  loosened  and  the  fornaldehyde  solution  applied  at  the  rate  of 
one-half  gallon  per  square  foot  of  soil  surfp.ce.  Apply  slowly  so  the  solution 
will  not  run  off,  and  immediately  cover  for  twenty-four  hours  the  wet  soil  with 
tarpaulins,  canvas  or  burlap,  previously  subi.-'.erged  in  the  solution.   This  pre- 
vents rapid  evaporation  of  the  formaldehyde  from  the  soil  and  insures  better  dis- 
infection. After  ton  days  the  soil  is  ready  to  plant.  Be  careful  not  to  rein- 
fect the  soil  'vith  tools  or  by  '.valking  aci'oss  it  when  planting.   This  t reatr.ien-'^

"Washed  sand,  and  potting  soil  can  be  ursily  disinfected  by  b;:2:irig  in  an 
oven  as  one  would  cook  a  five-pound  roast.   Be  sure  the  soil  is  thoroughly  wet 
'.vhen  balked.   Small  flo-'er  pots  containing  soil  cp.n  be  disinfected  by  submerging 
in  boiling  water  for  ten  minutes.   T''iere  are  other  methods  of  sterilizing  soil 
not  so  easily  applied  and  more  expensive,  but  I  will  not  go  into  that  now  but 
suggest  that  if  you  are  interested  f-orther  I  -vould  oe  glad  to  hoar  from  you  a- 
gain. 

"Thus,  often  diseases  axe  carried  on  the  seed,  Plo'-^er  seed  should  be  di=!- 
infected  before  planting.   Some  of  t?ie  larger  seed  such  rs  sunflowers,  four 
."^'clocks  ajid  castor  beans  can  be  easily  handled,  but  potxmia,  poppy  and  alys- 
:-:um  seed  are  us-or.lly  so  few  ml   so  small  that  they  arc  almost  imperceptible. 
In  regard  to  all  flower  seed,  I  woi^'ld  suggest  a  dust  treatment  with  Semesaji, 
To  dust  the  seed  purchase:,  in  the  correon  five  or  ten  cent  pa.ckets  of  seed, 
tear  off  a  cornei  of  the  packet,  insert  a  pinch  of  dust,  b;nd  over  the  torn 
corner  to  seal  it  temporarily  and  sha2ic  it  vigorously  for  a  minute.  La.rger  a- 
mounts  of  seed  can  be  trea.tod  in  the  sajnc  waj'  by  using  pint  or  quart  fruit  jars 
as  containers.

them  in  storage  to  reduce  th-;  decay  in  storaj'c  '  nd  insure  good  clean  stock  for 
fall  pl-^nting. 

"Tlie  d:,'infj  of  sceUings  soon  after  t'rcy  ei".ior.::o  from  the  soil  is  general- 
ly spoken  of  as  'danipoff.'   'Jliis  disease  is  caused  by  any  of  several  soil-in- 
habiting, parasitic  fungous  organisms  comnon  in  almost  all  Florrda  soils.   'I'he 
disease  is  enco'ontered  e-nnurJly  by  all  gardeners.   These  fungi  attack  the 
young  tender  seedlings  at  the  soil  line.   The  cells  in  this  area  are  killed  ajid 
collapse,  the  stem  is  vealcened  and  t?io  seedling  falls  over  and  dies.  This 
trouble  can  be  checked  by  applying  a  norLial  liquid  solution  of  Scmesan  so  that 
the  top  half  inch  of  soil  in  the  seed  bod  is  wet;  this  will  require  about  a 
quart  of  solution  to  ton  square  feet  of  soil  sur-face.   This  treatment  should 
ched-'  the  disease  in  thirty-six  hours.   It  can  be  repeated  after  U2  hours  if 
necessary.   Tlie  applicp.tion  of  this  solution  r;ill  not  harm  the  seedlings. 

"One  other  co.ution:   In  watering  flo-,^er  gardens  it  v;ould  be  more  desirc.cle 
to  apply  water  in  the  early  morning  tiia.n  in  the  evening  and  also  to  water  no.  ^ 
thoroughly  and  not  so  daftcn. 

"I  have  attempted  to  give  you  t"ie  information  you  asked  for  and  also  to 
dia.gnose  the  diseases  you  sent  to  us.   Possibly  some  additional  questions  will 
arise  ai"ter  reading  this  letter,  in  v:hich  case  I  would  be  glad  to  attempt  their

"Respectfully  yours,

Dr,  Allen  read  the  letter  with  considerable  interest  and  set  about  to  put 
into  action  the  recomiviend^.tions  he  received.  He  went  back  and  forth  from  gar-

Prmiing  Trees  and  Shrats  or  .Rat charing  Them  -  Wiich? 

Clias .  E.  Abl'Ott,  proTesiior  of  horticulture 
University  of  Florida  College  of  Agriculture 


Pinming  is  the  process  of  cutting  off  excess  or  undesirable  living, 
dying  or  dead  branches,  twigs,  roots  or  other  plant  parts  to  benefit  the  partt; 
that  remain. 

The  practice  of  pruning  is  as  old  as  huinan  hiotory.   It  is  referred  to 
specifically  in  Leviticus  (XXY,  3?  ^)  v-here  the  Children  of  Israel  are  told  to 
prune  their  vineyards  and  gather  the  frait  during  six  years,  but  in  the  seventh 
year  to  let  the  vines  go  unpruned.   In  five  oVaer  pa3sa5';es  in  the  Old  Testament 
figurative  reference  is  also  made  to  pi-aning  and  pruning;  hooks.   In  spite  of  the 
ancient  origin  of  the  practice  and  the  efforts  of  m-ii):y   iitvostigators  during  the 
intervening  centuries,  we  h.ive  by  no  means  reac  '.ed  the  limits  of  knov/ledge,  but 
can  claim  to  hr^v^  discovered  -mo  demonstrp.ted  only  a  few  important  principles  and 
useful  practices.   Th.?se  are,  ho., over,  unierstood  by  com^jaratively  few  of  the  peo- 
ple who  grow  plants,  and  ev  1  by  r  jiy  of  th3  self-styled  "priming  experts",  as 
evidenced  by  the  ill  effect,  observed  in  nuTiiciou^  fruit  and  siiade  trees. 

Proper  pruning  demands  kno,;ledge  of  pl':.nt  physiology.  Unless  the  person 
('.oing  the  pruning  has  "t  least  a  \ior'riri.%   knov/1  rd; ;■  ■;  of  how  plants  grow  he  will  be 
unable  to  prune  intelli.gently  to  procure  da^ir.  d  results.  On  the  coutr  ry  he  may, 
and  probably  will,  do  far  more  irnrn.:-di:ite  or  ultira-te  harm  than  good.   Simplj'  to 
top  off  limbs  with  an  ax-,  or  improperly  to  remove  others  with  a  saw  is  not  pruning 
but  usually  a  type  of  tre-^  "butchery  or  vivisection;  for  the  tr-^e  is  almost  sure  to 
suffer  and  sooner  or  later  die  from  th-;;  iffccts.  Again,  without  having  a  defi:iite, 
desired  end,  and  intelligently  working  within  the  scope  of  the  underlying  physio- 
logical principles  the  specimen  treated  may  develop  nothing  but  disease,  decay, 
death  and  disapxjointment . 


With  every  kind  of  fruit,  even  with  the  ornajr.ental  plants,  such  as 
:."xowering  shinibs,  tnere  arc  vv.rioas  systems  a*id  ido.lj  of  pi''u.ii:ig  and  training. 
These,  so  far  as  the  woody  fruit  and  hedge  plants  are  concerned,  differ  mainly 
in  the  form  which  it  is  designed  to  fivv;  the  plant  and  in  the  management  of  the 
annual  growtns .   Some  differences  are  '  le  to  variations  among  the  varieties  or 
L'i:ecies,  others  to  the  aims  sought,  still  ot  i^rs  to  environmental  conditions  or 
ty.e   fashion  of  the  locality,  and  many  art-  merely  a  matter  of  the  grov/er's  vvhim  or 
caprice . 

In  no  branch  of  pla-nt  culture  is  it  more  importojit  for  the  cultivator 
to  have  a  clear  mental  picture  or  ideal  for  which  to  strive  than  in  pruning. 


Plarts,  both  fruit  and  ornanieutals ,   r-:  :50  op-jn  to  accidents  of  cultiva- 
tion, fltorm,  disease  and  inr.ect  attacks,  that  it  is  often  impossible  to  secure, 
much  less  maintain,  an  absolut-ly  ideal  spocir'icn,  yet  the  ideal  plant  majst  be 
held  tenaciously  in  the  pnmer's  !.\ind  or  his  mechanic'il  skill  v.'ill  count  for 
naught  .'ind  the  plants  he  pruJus  will  necf  ssarily  be  unevjn  in  form,  appearance, 
development  and  prolificacy.  Vfith  a  clear  ideal  const-aritly  h?ld  while  at  v/ork 
the  primer  may  approach  oven  -riproximate  realization  of  his  desires,  and  v/ili  be 
able  to  counteract  undesirable  t'-mdencies  and  to  direct  the  energies  of  the  plant 
in  the  right  direction.  Wit.,  no  plants  is  this  uora  important  than  -with  young 
ones . 

Common  practice  demands  a  little  prTXf.i^w  v/ith  transplanting  operations 
but  it  is  difficult  to  make  any  hard  and  fast  rules  which  should  be  follov/ed.  The 
plants  vary  so  much  in  their  habit  of  growth  that  of  necessity  practices  suitable 
to  one  plant  may  be  detrimental  to  another.  However,  there  should  be  in  every  case 
some  relation  between  the  length  of  the  roots  ond  the  size,  height  and  diameter  of 
the  top,  vvhen  trees  or  plants  are  transplanted.   The  roots  ordinarily  left  on 
small  plants  -.vill  be  short,  while  on  larger  plants  the  roots  will  be  longer.   Im 
almost  every  case  the  largest  and  by  far  the  most  important  part  of  the  root  sys- 
tem is  left  in  the  ground.  Even  if  it  v/ere  possible  to  take  up  the  entire  root 
system  with  the  plant  or  tree,  its  close  contact  v/ith  the  soil  v/ould  be  jjlestroyed 
and  is  not  reestablished  except  e.s   new  roots  grow. 

Some  plants,  such  as  arborvitae  and  azaleas,  have  finely  branched  root 
;;/Suems,  while  others,  as  the  pecan,  p  .rsimmon  and  crape-myrtle  have  very  poor 
r'^ot  systems.  Yet  such  plants  as  persi'vimon  and  crape-myrtle  can  be  transplanted 
.:.  easily  as  can  citrus  or  any  of  the  ether  plants  with  nuch  branched  root  sysr? 
tens,  if  the  job  is  done  at  the  proper  time. 

The  tops  of  most  woody  plants  snould  be  pruned  back  to  establish  an 
pqailibrium  betv/een  the  functions  of  the  top  -rtid  roots.  This  is  necessary  that 
the  amciont  of  water  lost  by  transpiration  from  the  top  will  not  exceed  the  amount 
of  water  absorbed  by  the  greatly  reduced  root  system.   If  this  is  dore  the  chances 
for  success  are  much  greater  tnan  if  the  top  is  large  in  proportion  to  the  roots. 

In  pruning  the  tops  of  plants  and  trc:  i  every  precaution  should  be  taken 
to  prevent  injury  to  the  p". is  th^t  remain.  Mary  casvs  of  d^cpy  and  permanent  in- 
jury to  trees  can  be  traced  to  improper  pruning.  One  of  the  most  common  mistakes 
is  leaving  stubs  of  branches  when  ticy   are  cut  ofi'.   In  renoving  a  branch  the  fina!^ 
cut  should  be  made  as  close  to  the  t runic  or  branch  as  possible  and  in  such  posi- 
tion that  the  face  of  the  wouiid  v/ill  be  parallel  to  the  general  flow  of  the  sap 
:in  the  part  from  which  the  branch  -./as  cut.  A  stub  left  while  proning  is  like  a 
"""-lind  alley,  the  sap  cannot  circulate  through  it  and  the  living  tissue  soon 
dies.  Too  frequently  limbs  are  broken  off  by  storms  and  the  resulting  stubs  are 
av  much  of  a  menace  as  those  thi.t  man  may  leave. 

A  sharp  knife  is  often  desirable  for  pruning  small  trees  and  sarubs 
p.n':  should  always  be  in  reach.  Pruning  shears  are  less  desirable  for  small  plant?, 
because  too  frequently  they  bruise  the  bark.  Most  of  the  injTiry  can  be  avoided 
if  the  sharpened,  movable  shear  is  held  next  to  the  tree  stem.  A  variety  of 
Tn-iuiing  saws  are  available.  For  small  branches  and  limbs  a  20-inch  curved  pruning 
oavv  is  satisfactory.  Tv/o-cdged  pruning  saws  should  not  be  used  bec--ase  tne  extra 
edge  frequently  damages  nearby  limbs. 


-3- 

Snall  br-a-nciies  should  le   r-.-^oved  v;ith  c   o   cuts.  First  make  an  -undercut 
until  the  saw  binds,  then  cut  do.vn  v/ifh  the  saw  directly  above  ths  und.-^rcat  and 
proceed  -ujitil  the  two  cuts  uest  or  ur.til  the  limb  bruaics  oi'f .  All  cats  should 
be  clean  and  snoobh  so  that  no  splinters  or  t-ars  r^^r.iain  in  the  bark. 

Lar^rff  limbs  usually  have  to  b,'  rvmoved  v/ioh  at  least  three  separate  cuts 
to  prevv:nt  the  edge  from  splittinti  and  to  kesp  the  bark  from  tearing.  First  re- 
move tht  bulk  of  the  lirab  12  to  IS  inchis  beyond  the  first  cut,  in  the  raauner  d^::- 
scribed  for  small  limbs.  Usually  it  id  easier  to  make  an  \-uidercut  until  the  saw 
pinches  paid  then  proceed  with  a  cut  from  aJjove,  a  fevir  inches  aliead  of  ths  luider- 
cut.  The  weight  of  fJie  branch  vdll  break  it  off  but  the  undercut  will  prevent 
tne  bark  from  tearing  down.  Next  take  off  the  stub,  which  can  oe  done  easily 
with  th^  heavy  linb  ^:on-?.  The  cut  shrr-.ld  be  flush  with  the  trunl:  even  thcu/^a  t'.e 
scar  will  be  fairly  large. 

All  wo-jxids  of  an  inch  or  mora  in  di-:>m3ter  should  be  painted  over  v/ith 
white  lead  paint  or  some  other  good  tree  woiuid  dressing.  Neglect  of  this  precau- 
tion may  lead  xiltimately  to  the  loss  of  a  tree.  Deca^-  may  set  in  at  the  site 
of  the  open  wound  and  travel  downward  into  the  comter  of  the  tnuil':. 

The  time  of  priudng  varies  with  different  sprcies  but  as  a  general  rale 

the  work  should  be  done  v/hile  the  tree  is  dormant.  Deciduous  trees  may  be  primed 

late  in  their  dormant  season,  and  evergr.;  tls   at  any  time  except  when  actively 
growing. 

Trocs  and  s'-irabs  t  -.t  form  their  il0'..;r  ouds  during  summer  and  fall 
vrevious  to  the  time  when  th-.  blc  ssr  Cis  opf:n,  S' ch  P'^i  azaleas  and  spireas,  should 
.ir-  pruned,  as  a  general  rule,  imiiediately  :-'ft-:;r  the  plants  have  finished  flowering. 

Those  plants  that  produce  ti.,.ir  f lowers  on  shoots  of  current  season's 
growth,  such  as  abvlia,  hibiscus  and  roses  should  be  pruned  during  the  dormant 
"■ea'^jon  so  as  to  avoid  interfering  v/ith  th-.  production  of  f  lov.'srs . 

Natur.,  is  not  at  all  concerned  'w-ith  the  prod^iction  of  large,  well- 
jhaped  flowers  (such  as  roses)  that  gardeners  like.  Her  only  aim  is  to  produce 
seeds,  the  more  the  better.   Consequently  an  impiniri-.d  rose  bush  is  likely  to 
produce  a  great  quantity  of  relatively  small  flowers  of  no  particular  shape  and 
value  for  garden  purposes. 

The  purpose  of  pr-LU-iin'3  ro^-^s  is  t'l  o  fold:  to  conserve  the  energi'-^'S  of  th^ 
plant  by  directing  its  vitality  into  those  branches  which  can  best  use  it,  and  stil] 
iuvther  to  concentrate  it  into  the  proper  nui.iber  of  flov/ors  that  the  plant  can  de- 
velop to  perfection. 

Pruning,  consequently,  includes  t'u-o-  distinct  operations,  thinning  out, 
v/h-ich  means  completely  removing  dead  anr'.  undesirable  v/ood  which  nature  would  de- 
t-'oy  anyway,  thus  permitting  new  grov/th  to  devote  its-jlf  to  the  business  of  pro- 
i:ing  flov/ers;  and  shortening  the  remaining  sh  ots  to  control  the  number  of 
i'.-wers;  30  that  th^-y  may  be  cr^:. ditable  i.i  f.'.ir-.  an.",  size. 

For  pru;iing  bush  rosc  s  in  North  FloriO.a  the  best  seasons  are  early  in 
October  and  in  late  F'-)bnv-'ry.  PartJier  South,  the  October  pnuiing  m-y  be  delayed 
and  the  spring  pruning  advanced.   In  pruning  ros^s  one  should  first  remove  all  dead

Flowering  Trees  for  Florida 


A.  F.  Ccirap,  head 
Department  of  Horticulture,  Florida  Experiment  Station. 

In  selecting  ornamental  trees,  we  ordinarily  consider  them  for  their 
va,lue  as  shade  or  as  a  haclcgrotuad  for  other  ornamentals.   In  Florida,  however, 
we  have  a  siirprising  ntimber  of  trees  that  are  notable  for  the  beauty  of  their 
flowers.   Some  of  these  are  also  splendid  foliage  trees  and  -rould  gain  a  place 
regardless  of  their  blooming  habit,  whereas,  there  are  many  others  which  are 
notable  only  or  primarily  for  their  blooms.   In  the  latter  group  v/e  find  r.iany 
deciduous  trees  i^hich,  if  planted  in  quantity,  give  too  much  of  a  northern 
atmosphere  during  the  winter  months ,  where- s  Florida  should  be  notable  for  the 
tropical  or  subtropical  atmosphere  of  its  ornamental  plantings.  The  deciduous 
f levering  trees  come  into  consider  ,tion  m;L;t  extensively  for  northern  Florida, 
where  many  of  them  are  native  and  v.'-here  it  is  more  difficult  to  maintain  winter 
plantings  of  a  subtropical  appearai^ce. 

Because  many  of  the  deciduous  trees  are  natives,  we  will  discuss  them 
first,  together  with  other  flowering  trees  for  northern  or  central  Florida. 
Two  of  these  are  familiar  to  all — the  Redbad,  or  Jtidas  tree,  and  the  Dogwood, 
Both  of  these  grow  wild  in  Florida  liainmccks  and,  while  they  are  leafless 
during  the  winter,  they  outdo  themselves  during  the  spring.   The  Redbud 
is  one  of  the  first  trees  to  burst  into  blooi.i  in  the  spring  and  its  v/ealth 
of  small  pink  flowers  is  produced  before  the  leaves  and,  v/hen  displayed 
agr.inst  a  background  of  green,  it  is  very  be-^^utifxil.   The  tree  is  usually 
small  and  frequently  poorly  shcped  and  should  be  plraited  with  other  trees. 
The  Dogwood  is  another  c:\rly  spring  bloomer  which  adds  beauty  to  the  Florida 
hammocks  and  to  countless  hone  i>lantings.  Fneu  in  full  bloom  the  tree  is 
almost  a  mass  of  white.   The  f lowers  themselves  are  snail  and  inconspicuous 
but  the  display  is  caused  by  white  bracts  or  modified  leaves  surrounding  the 
actual  flowers.   This  condition  is  not  uncorm.ion  in  plants,  the  well  kno-vm 
Bougainvillea  having  small  flowers  while  the  wealth  of  color  comes  from  the 
subtending  bracts. 

Another  native  deciduous  tree  that  is  a  thing  of  beauty  dui'ing  the 
spring  if  the  wild  crabapple.  Under  Florida  conditions  it  grows  to  a  height 
of  25  ft.  and  can  be  advantageously  used  tj  give  a  touch  of  color  when  it  is 
badly  needed  in  early  spring.  Other  deciduous  trees  that  are  notable  for  thfir 
bloom  and  v/hich  are  suited  to  north(.;rn  Florida  are  the  Catalpa,  which  flov/err 
in  early  suianer;  Aleurites  f  ordj. ,  the  tung  tree,  which  bears  a  profusion  of 
v/nite  and  pink  bloom  in  the  spring;  the  fringe  tree,  or  Old  Man's  Beard,  a 
native,  vAiich  bears  in  spring  a  wealth  of  t'-reenish-white  flowers,  Vitex 
/.jgnus-castus,  commonly  known  as  the  Chaste  or  Hemp  tree,  and  Koelreuteria 
f 0  mo  Sana ,  which  flowers  in  October, 


In  using  any  of   the  decidujus  flowering  trees >  the  fact  that  they  are 
leafless  in  winter  must  he  torne  in  nind.   They  should  be  planted,  if  possible, 
so  thr.t  they  have  a  green  background  in  '.rinter  and  particularly  during  the 
blooming  season,  if  they  bloon  before  the  leaves  appear*   It  is  no  easy 
natter  to  lay  out  grounds  so  that  such  trees  v/ill  bo  inconspicuous  during 
their  leafless  period,  but  with  care  in  planning  this  caJi  be  done  and  the 
colorful  results  are  well  worth  while. 

In  addition  to  those  we  have  already  discussed  for  northern  ojid  central 
Florida,  v/e  have  a  nunber  of  others  of  real  value.   Some  of  these  are  decid- 
uous but  only  for  a  short  period,  while  others  get  a  new  crop  of  leaves  -  . 
coincidentally  vdth  the  loss  of  the  old  leaves,  so  that  they  are  never  bare 
of  foliage.   The  Magnolia,  which  grows  vdld  through  Central  and  North  Florida, 
is  notable  for  its  large  white  flowers  and  its  glossy  f Jliage.  A  relative 
of  the  Magnolias,  the  tulip  tree,  or  yellow  poplar,  is  found  native  along 
streans  and  is  frequently  planted.   The  Minosa,  Albizzia  Julibrissin^  is 
frequently  planted  in  dooryards  through  North  and  Central  Florida  and  its 
fernlike  foliage  and  flowers,  with  a  profusion  -if  long  -and  conspicuous  stamens, 
nake  it  notable  in  its  class.   The  Loblolly  Bay  and  the  Jerusalem  Thorn  about 
complete  the  list  of  flowering  trees  for  northern  Florida, 

For  the  central  and  southern  areas  of  the  state,  the  choice  of  flower- 
ing trees  covers  a  much  wider  range  of  possibilities,  and  many  of  the  species 
are  notable,  not  only  for  their  bloom,  but  also  for  the  beauty  of  their  foliage 
and  their  general  value  as  ornamental  trees.  Relatively  few  of  these  are 
deciduous  in  the  sense  that  they  remain  leafless  throughout  the  winter,  though 
many  of  then  are  leafless  for  periods  of  from  one  to  eight  v/eeks,  generally 
during  the  spring.   This  period  of  leaflessness  is  usually  not  sufficient  to 
condemn  them  for  general  ornamental  usage  and  they  are  consequently  not  sharp- 
ly distinct  from  the  evergreen  trees.   Some  of  these  flower  during  the  leafless 
period  and  for  that  reason  the  flowers  stand  out  even  more  strikingly  than  do 
the  flowers  of  the  evergreens. 

Many  of  these  flowering  trees  are  very  sensitive  to  cold  and,  in  choos- 
ing flowering  trees  for  central  or  southern  Florida,  great  care  should  be  used 
to  pick  those  species  which  will  stand  the  degree  of  cold  that  nay  be  expected 
in  the  locality  where  they  are  planted.   Soi.;e  will  be  found  adapted  only  to 
the  lower  East  and  West  Coasts,  \/here  frost  seldom  occurs,  vvhile  others  are 
suited  to  protected  locations  in  Centrol  Florida,   Since  the  number  of  avail- 
able species  is  so  large,  it  is  possible  to  nalre  selections  with  a  particular 
location  in  mind  and  thus  avoid  ?jay  severe  cold  damage.  Most  of  the  species 
that  have  already  been  discussed  for  North  Florida  V7ill  do  well  in  Central 
Florida  but  many  of  them  will  not  do  well  in  extreme  South  Florida.   Some  of 
the  genera  already  discussed  for  North  Florida  include  other  species  which  are 
adapted  to  southern  Florida.  AlhijSzia.  ^lliiilisjiji.  is  grovra  throughout  the  north 
and  central  area,  as  previously  mentioned,  whil^  jU-b i z zia  L cbbek ,  knov/n  cor.mon- 
ly  as  the  Woman' s- Tongue  tree,  is  grovm  only  in  south  Florida;  the  tung  oil 
tree  ^J.e-arites,  gordi.  and  A.  montanft  are  adapted  to  northern  Florida,  while  4. 
mQluccayiCi,.:..t:5£da^rand  l^rispernja.  grow  satisfactorily  in  the  southern  districts, 
A.  moluccana  being  an  evergreen. 

The  outstanding  flowering  tree  of  southern  Florida  is  the  Royal  Poinciana, 
tropical  in  habit,  which  is  grown  throughout  the  lovver  east  and  west  coasts 
and  in  well  protected  locations  in  central  Florida.   Generally  a  low-spread- 
ing tree  with  fern-like  foliage,  it  carries  during  the  early  summer  months  a 


-  3  - 

nassive  cap  of  trilliant  scarlet  flov/ors.   The  individur,!  flowers  are  two  to 
three  inches  across,  vdth  rich  scarlet  petals,  except  for  the  x^jpdr  petal, 
which  is  tinged  with  yellow.   These  flowers  are  barne  in  lar£;e  racemes  and 
fomi  a  scarlet  layer  overtopping  the  gree.i  of  the  foliage.   The  tree  grows 
rapidly  and  nay  reach  a  height  of  30  ft.  v.lth  a  spread  at  least  equal  to  the 
height  cjid  often  nore.  Probably  no  other  floi,/ering  tree  is  as  strongly  favor- 
ed for  South  Florida,  and  its  rapid  grov/th  and  v/ide  adaptation  to  soil  condi- 
tions has  r.;r.de  it  extrenely  useful  for  nany  types  of  planting. 

Another  of  the  greatly  favored  floT„ering  trees  for  Southern  Florida 
is  the  Jacaranda.  Like  the  Royal  Poinciana,  it  lias  a  fern-like  foliage  and 
in  the  period  frora  April  to  June  bears  a  profusion  of  lavender-blue  flowers, 
in  long  loose  panicles.   Just  prior  ti   the  blooning  period,  the  tree  is  par- 
tially or  wholly  without  foliage  for  a  short  tine.   This  lias  been  one  of  the 
favorite  flowering  trees  of  Florida  for  nany  years  and  probably  has  a  slight- 
ly v/ider  clinatic  adaptability  than  has  the  Royal  Poinciana. 

There  are  nany  other  trees  which  are  used  extensively  on  account  of 
their  flowers,  though  probably  they  are  not  .'■.s  generally  knovm  or  as  extensive- 
ly used  in  hone  plantings  as  the  two  nentionod  above.   The  two  species  of 
Bauhinia ,  naraely,  alba  and  punoureai  coroonly  known  as  orchid  trees  in  Florida, 
are  being  nore  extensively  used  tnan  in  the  past,  particularly  for  roadside 
plantings,  oJid  their  large  flowers  are  very  beautiful  during  the  spring,  they 
bear  a  narked  resemblance  to  orchids. 

Among  the  species  tliat  present  a  shovjy  and  beautiful  bloom  nust  be  re- 
corded the  various  species  of  Cassia  that  are  grown  in  Florida,  Like  a  number 
of  our  other  flowering  trees,  the  Cassias  belong  to  the  fanily  Leguninosae, 
the  notable  representative,;  of  this  family  being,  of  course,  the  Royal 
Poinciana.   The  Cassias  in  Florida  are  all  snail  trees  with  finely  divided 
foliage  and  a  profusion  of  bloon  in  spring,   Passia  fistul".  has  yellow  flovif- 
ers  and  is  frequently  coJled  the  Golden  SliowBr,  C.  sia!.iea  has  pale  yellow 
flowers  and  C_.  nodosa  has  pink  flowers,  as  has  C.  grandis, while  Q_.Beareana  has 
beautiful  yellow  flowers.  All  species  need  good  protection  fron  cold. 

Two  other  species  that  are  notable  for  their  great  wealth  of  bloon  are 
Spathodea  campanulata  and  Stenolobiuxo  stalls.    The  forner  is  known  commonly  as 
the  Fountain  tree  or  Tulip  tree.   It  h.:vs  large  scarlet  blossons  which  are  pro- 
duced in  great  profusion  in  short  raceiies.   The  tree  is  evergreen  and  may 
reach  a  height  of  60  to  JO  ^t.   It  is  a  worthy  relative  of  the  flame  vine, 
belonging  to  the  sDXie  fanily.   Stenolobj-'.m  stojis  also  belongs  to  the  Bignor.ia 
far.iily  and  is  commonly  known  as  Yellow  Elder,   This  species  does  not  make  an 
outstonding  tree,  being  rather  shrubby  in  character.  It  is  notable  for  its 
beautiful  yellov/  flov/ers,  b^rne  in  the  fall.   Planted  with  other  ornanentalo- 
it  gives  a  pleasing  touch  of  colsr  during  the  fall  season. 

In  adc'ltion  to  those  already  mentioned  for  south  Florida,  there  are  a 
number  of  others  ha,ving  blooms  of  beauty  or  of  interest.   A  number  of  these 
do  not  present  the  brillieuit  sort  of  show  that  is  characteristic  of  the  Roya' 
Poinciana  or  Jacaranda  but  the  single  flowers  are  of  outstanding  beauty  or  ol 
great  and  interesting  peculiarity,  pillenip.  indica.  while  little  used  as  yet.- 
is  a  sjjlendid  ornamental  both  on  account  ,f  its  foliage  and  its  beautifiol 
white  flowers  \7hich  are  6  to  8  inches  across.   The  various  species  of  Pl-untric, 
which  conr.ionly  are  known  under  the  nar.ie  of  Frangipani,  produce  a  \7ealth  of 
flowers,  various  species  giving  flovver  colors  of  red,  yellow  and  white,  the 


flov/ers  appearing  for  several  noi.tli<^  in  the  ^'ear,   Tci'be'b.uia  p^gntaph.ylla 
produces  a,  notable  ?xioui"it  of  lon^  pink  fl.wers  in  the  lat<i  -.Tinter  and 
spring  nonths.   One  of  thj   species  havin ;  a  flower  of  outstandini^  pecu- 
liarity aiid  interest  is  Cournupito,  f'.r.iariousis ,  Jaiov/n  as  the  cannon  ball 
tree  aju.  a  relative  of  the  Brazil  nut.   The  flov/ers  are  very  large  and  of 
a  peculiar  shape  and  are  borne  on  long  woody  racenes  on  the  trunk  and  larger 
brojiches.   The  flov/ers  are  reddish-yellow  on  the  out  sic' e  and  crimson  v.-i  th- 
in and  pectiliarly  folded.   No  piarticular  display  of  bloon  is  present  but 
the  peculiar  nethod  of  be^jring  the  floT;ers  together  vdth  their  peculiar 
shape  nakes  it  a  very  interesting  tree.   It  is  not  possible  to  mention 
all  of  the  valuable  specios  here  but  this  will  give  an  ideo.  as  to  the 
extent  of  the  available  naterial. 

In  placing  flowering  trees  in  ornoxiental  plojatings,  their  character- 
istics should  be  studied  carefully  with  regard  to  the  location.   The  list 
of  available  nia.terial  is  great,  and  we  have  only  touched  the  surface  here. 
To  be  valuable  as  a  blooming  ornoxiental,  the  flowers  should  be  showy  aiid 
should  last  for  a  long  tine.   Mpjiy  trees  are  beautiful  in  bloon  but  the 
bloon  passes  too  quiclcly  to  npice  then  of  great  value,  unless  they  are  out- 
standing for  other  reasons.  Others,  while  having  narevelous  single  bloons, 
do  not  bloon  heavily  enough  to  naJ-e  rxi   attractive  shov.'.   Still  others,  v/hile 
carrying  beautiful  bloons,  are  poorly  adapted  to  specimen  planting  owing  to 
their  irregular  sliape  ajid  must  be  placed  with  other  plantings.  A  proper 
selection  of  blooming  s^pecies  properly  placed  will  add  nuch  to  any  or.iaiuenti^? 
plDjiting  by  giving  a  succession  of  colorful  bloons  to  brealc  the  green  of 
other  shrubbery  and  trees.

The  Development  of  Garden  Plants 

P.  H.  ?enn, 
Assistant  professor,  farm  crops  and  genetics 

University  of  Flo..'ida,  Colle,ge  of  Agriculture. 

Many  gardeners  are  now  plannin,^  to  grow  flov.-ers  in  their  ycrdc  or 
gardens.   On  turning  the  pa^,cs  of  a  seed  catalog  or  garden  book,  they,  no  doubt, 
are  profoundly  impres;;ed  wi:h  ohe  great  variety  of  plants  available.  One  wonders 
how  and  from  what  source  t'.ie  coedsman  has  ar.seiibled  so  vast  a  collection  of 
varieties  of  different  ornamental.-;.  Great  u.-iTibt. j.-"?  of  varieties  are  offered  among 
garden  plants.  How  has  this  great  variation  in  plant  types  and  forms  been 
developed? 

One  has  only  to  turn  back  the  pa^'es  of  memory  a  few  years  to  realise 
that  many  of  the  plant  forms  and  types  we  enjoy  today  were  not  knovm  or  heard  of 
.20,  10,  or  even  five  years  ago.   Seed  catalogs  undergo  annual  revisions  to  keep 
pace  with  new  developments  in  plants.  Some  of  the  older  varieties  and  types  are 
passing  out  of  use  and  newer  pioductions  are  offered  in  their  stead. 

Nature  herself  is  constantly  making  changes  in  the  architecture  of  her 
materials  and  productions.  Such  chanf:es  in  nature  man  calls  "sports"  or  "breaks" 
or  more  technically  "mutations".  Man  has  preserved  many  of  these  changes  and 
uocd  them  in  bringing  into  existence  newer  plant  developments.   Such  changes  ma.y 
occur  at  different  times,  and  under  different  conditions,  wherever  the  plant  may 
be  found  growing.   These  changes  may  take  place  among  plants  growing  in  the  wild 
state,  but  changes  among  wild  plants  are  more  likely  to  pass  unnoticed  than 
changes  in  plants  under  cultivation  a.id  observation. 

Improvements  among  plants  have  been  brought  about,  not  by  any  one 
person,  but  by  a  number  of  workers  la.boring  in  different  fields.  The  explorer, 
the  collector,  the  plant  introducer  and  the  -olant  breeder  have  all  combined 
their  efforts  in  bringing  about  the  vonderful  changes  noted  among  garden  plants 
of  today.  The  collector  labors  to  bring  together  as  r.:any  variations  as  possible 
of  a  particular  grour>  of  plants.  The  explorer  goes  out  into  unexplored  and 
uninvestigated  regions  and  searches  for  new  and  different  kinds  of  plants  peculiar 
to  those  regions.  The  plant  iutroducer  assembles  plants  from  different  foreign 
lands  and  introduces  them  into  ot'riGr  continents  where  they  have  never  been  tried. 
It  remains  for  the  plant  breeder  to  utilize  the'jc  variations,  wherever  they  may 
be  found,  or  from  whatever  source  they  may  have  come.  He  employs  his  knowledge 
of  the  laws  of  inheritance,  and  works  to  bring  forth  new  types  and  new  corabinatiors 
of  characteristics  in  a  plant  which  he  hopes  will  be  more  useful  and  more 
desirable  to  man  than  those  already  available. 

What  are  some  of  these  desirable  characteristics?  This  is  not  an  easy 
question  to  answer  since  desirable  characteristics  for  one  group  of  plants  may  be 
quite  different  from  those  desired  in  another  group.  The  plant  breeder  krows  that 
man  is  ever  demanding  something  better  in  plants.  These  demaxids  are  often  in  the 


,2- 


nacure  of  a  change  in  come  Vijgetati\e  fo'on  of  tl.o  plant,  a  aiffcronie  in  the 
qv-ality  of  the  fruit  o:.'  color  of  the  flov:or,  £-re>.ter  proviucing  abilities  and 
ability  to  i-'ithstand  the  i-i^^orc  of  r  dif  f  ere  t  er.vironraent ,  or  to  survive  attacks 
of  disease  and  insect  pests. 

As  v/e  look  around  T7e  see  varieties  that  are  tall  and  those  that  are 
dwarf.  There  are  those  with  clinihing  habits  ani  others  v;ith  an  upriglit  ftaturo 
and  still  others  that  are  spreadinf'-;  and  have  a  lo.v  habit  of  gro'.7th.  There  is 
also  form  in  leaf,  in  fruit,  and  flower,  E::araples  of  these  various  forms  come 
immediately  to  mind  v/hen  v/e  turn  our  thout~hts  to  the  flowering  plants  around  ti.s 
average  home.   Qualitj'-  is  a  factor  of  paramount  importance  in  developint;;  field, 
tiuck  and  horticultural  plants.   Color  of  flower  will  ever  be  foremost  in  mind 
"hen  seeking  improvements  among  garden  plaaits  groY;n  for  their  flowers.  The  public 
ever  anxious  to  procure  something  new  cand  different  in  the  color  scale. 


■»  r 


Manv  garden  plants  are  planted  in  beds  and  trseri  for  cut  flowers.   In 

either  case  the  ability  to  produce  flowers  is  essential.  It  is  not  uncommon  for 

the  breeder  to  find  a  plant  that  produces  flo\.ers  of  fine  quality,  but  the  flower;:, 

are  produced  in  quantities  too  few  for  the  plant  to  be  of  commercial  iraportpjic?,; 

There  is  the  desire  to  grow  certain  types  of  plants  in  distant 
latitudes  and  at  different  altitudes;  arid  so  extend  their  limits  of  culture.   In 
an  effort  to  meet  these  demands,  hardier  varieties  thr.t  will  grow  under  more  trying 
conditoons  are  produced. 

So'.ie  soils  are  infested  with  plant  diseases,  and  the  need  arises  for 
varieties  that  sho'.v  resistance  to  their  attacks.  These  diseases  as  vrell  as 
insect  pests  hinder  the  growth  uf  plants.  At  once  a  demand  is  made  on  the  breeder 
for  nev;  varieties  and  tj^pes  that  may  be  ,^i'own  s"v  ccessfully  under  such  conditions. 
Soil  differences  exist  in  ot'ier  respects  -  some  are  acid  while  others  are  allzaline 
in  nature,  some  are  rich  in  plant  nutrients  while  others  are  poor  and  much  depleted. 
Through  years  of  developing  and  teftinr ,  the  bree;"''ei-'  has  developed  varieties 
adapted  to  growing  under  va.ried  soil  conditions. 

Seasonal  habits  must  be  reckoned  v/ith  in  plant  development.  There  are 
the  annual,  biennial,  ani  perennial  plants.  Ai.iong  the  annuals  there  are  those 
furnishing  flowers  early  in  the  season,  others  blooming  late,  and  some  that  are 
good  producers  practically  throughout  the  growing  season.  Even  within  the  same 
variety,  in  some  instances  strains  have  betni  developed  that  are  e?rly  a?id  we  hs^/e 
others  that  are  late.  Such  differences  arc  inherited.  They  are  produced  by 
nature  and  not  by  man.  Man  can  only  preserve  and  utilize  them  in  an  effort  to 
br:'ng  about  a  new  type  of  plant. 

Let  us  now  turn  our  attention  to  a  few  of  the  common  and  well-known 
t,-.-J.3n  plewiitc  and  see  if  wc  can  note  a^v''  recent  chanf^ct,  and  de". elopi-i'-nts  a:.iong- 
then,  Ta]'e  for  example  the  zinnia  -  the  Old  Maid  of  the  garden.  This  is  a  flower 
that  came  originally  from  Mexico.   It  was  introduced  into  European  gardens,  and 
there  naraed  in  honor  of  an  European  pi  Tician,  Dr.  Zinn.   TThen  the  zinnia  was 
first  intro.luced,  its  chief  claim  for  existance  was  thit  it  was  an  easily  grown 
annual,  enduring  under  various  kinds  of  hardships  and  neglect,  and  that  it  had  a 
long  season  of  bloom.  Originally  the  flov/er  itself  was  unI:ompt  and  ragged,  with 
colors  far  from  the  color  standards  of  today.   Many  will  recall  the  dingy  whites, 
the  greenish  yellows  and  the  murky  reds.  But  note  the  r.iraculous  c}'.?-nges  that 
have  come  about  when  one  views  the  range  from  fiery  red  fch  the  delicaic  pastel 
shades  in  the  zinnia  gardens  of  today. 


■i>- 


'2he   ziimia  has  achieved  its  rreatest  advances  since  about  ^920  vvhen  a 
California  f;rower  started  developing:  this  connion  (garden  flo'.ver.  NoL  only  more 
and  purer  colors  have  been  produced,  but  variations  in  shape  and  form  and  size  have 
been  achieved.  There  is  the  r.ianmoth  dalilia-flowered  form  which  ai:peared  sone  20 
years  a{ro  in  the  fields  of  a  seed  £;ror.er.   It  a-npeared  as  just  one  plant  in  7/hich 
the  petal  arranr;ement  of  the  old  type  zinnia  had  been  chanj-^ied  by  nature  into  a 
more  graceful  and  beautiful  combination.   This  orijftina.l  dahlia-flowered  zinnia  was 
red  in  color.   Seeds  of  it  were  saved  and  from  this  planting  a  mixture  of  f levers 
of  several  colors,  still  retainiiv:  the  dahlia  form,  were  produced.  Then  followed 
several  years  of  {growing  an:L  selection  before  the  dahlia  type  was  fixed  in  various 
colors.  But  look  at  the  zinnia  collection  of  today.   It  is  the  pride  of  many 
gardens,  presenting  itself  in  many  attractive  for.ns  and  "orgeous  colors.   In 
addition  to  the  courtly  dahlia-forms,  there  are  the  dwarfs  in  their  array  of 
splendor,  the  quilled,  the  lilliput  or  pon.pons ,  and  the  richly  colored  giants,  all 
from  the  once  neglected  garden  plant  -  The  Old  Kaid. 

TKiat  has  been  accom.plished  over  a  relatively  brief  period  for  the  zinnia, 
has  been  realized  also  for  many  other  annual  plants.  One  need  mention  only  a  few„ 
There  are  the  petunias  among  which  v.-e  find,  the  single  and  plain  petaled,  the 
fimbriated  and  fringed,  the  fluffy  raffles  and  the  giant  double  fringed  with 
flowers  in  enormous  in  size.   At  the  same  time  the  color  range  has  been  extended  to 
meet  the  demands  of  the  most  fastidious. 

Among  the  nasturtiums  there  are  both  dvrarf  and  cligibing  types,  toge'hcr 
with  a  brilliant  color  range  never  before  seen  in  this  plant.   The  sweet-secnted 
double  Golden  Gleam  is  probably  the  newest  accomplishment  of  nasturtium  breeders. 


"         Many  new  and  improved  types  far  superior  to  the  small  flowers  of  the  old 
form  have  been  developed  among  the  marirolds.   There  are  the  tall  and  the  dwarf 
varieties  with  a  scale  of  colors  running  through  shades  of  lemon,  orange,  gold 
e.nd  maliogany  brown.   The  doubles  are  m?.rhed  improvements  over  the  old  form.

The  calendula  or  Scbtch  marigold  is  a  flower  that  is  comrr.on  in  Florida 

during  the  winter  season.  Here  one  finds  yello-,  orange  and  primrose  colors  that 
are  very  showy.  More  recently  there  has  bee^n  added  to  the  list  of  t\'pes 
chrjAsanthemum-f lowered  varieties  with  loose  petals  and  those  with  long  quilled 
and  twisted  petals. 

Vast  improvements  have  been  made  among  numerous  other  annual  f levering 
plants,  common  in  Florida  gardens.   Let  us  not  thini:,  hov/ever,  that  all  the 
developments  and  accon;^lishnents  have  been  among  the  annuals.  Marvelous  changes 
have  been  developed  among  the  biennial  and  the  perennial  flowering  plants  as  well. 
To  mention  a  few  such  as  the  gladiolus,  ainaryllis,  the  canna  and  the  iris  and  d.ay- 
lily  -  plants  common  in  Florida  gardens  -  one  recalls  the  great  variation  in  Ij-pe 
and  form  of  plant  and  color  ranges  among  the  flowers  and  in  some  insta,nces  color 
rarges  in  the  foliage. 

Hybridization  cr  cross-breeding  is  a  method  used  extensively  by  plant 
breeders  in  developing  many  garden  plants.   It  consists  in  the  crossing  of  a 
plant  possessing  certain  characteristics  with  another  plant.  The  cross  is  mad; 
in  the  hope  of  combining  the  desired  characteristics  of  each  in  a  single  plant.

This  has  been  a  fruitful  metliod  for  the  breeder.  He  has  used  the  hereditavy 
variations  or  mutations  of  nature.  These  variations  have  oeen  ma'^.e  available 
through  careful  observers  noting;  rare  sjid  distinct  types  a,ppearing  abruptly 
among  their  plants.  Max^v  of  these  variations  have  been  preserved  and  later 
used  by  the  plant  breeder  as  foundation  stocks  for  a  new  variety. 

When  hybridization  is  to  be  undertaken  it  is  essential  to  understand 
the  structure  of  the  flov/er.  Many  plants  have  both  male  and  female  organs  in 
the  same  flower.  Before  coossing  is  attempted  it  is  necessary  to  remove  the 
male  organs  of  the  flower  before  the  pollen  is  shed.  The  flov/er  is  then 
protected  by  a  small  paper  bag  until  it  is  receptive  to  pollen.  This  prevents 
contamination  from  undesirable  pollen.  YJhen  the  flo\7er  is  receptive,  pollen 
is  then  taken  from  another  plant  and  placed  upon  the  female  flor/er.  If 
pollination  is  successful  seed  v/ill  ripen  and  later  produce  the  hybrid  plants, 
These  hybrids  are  usually  very  unstable.  They  must  be  grown  several  years  and 
from  them  the  desired  type  is  selected^  Further  testing  is  necessary  to 
determine  v/hen  the  type  has  become  fixed  and  is  ready  to  be  offered  as  a  nevr 
production. 

The  wonderful  changes  and  developments  among  the  garden  plants  of 
today  are  the  accomplishments  of  f-.e  plant  breeders  and  other  plant  workers 
working  together  to  bring  about  thc-e  marvelous  improvements.   They  are  not 
satisfied  but  are  ever  on  the  alert  for  something  better,  working  for  something 
different,  something  more  useful  and  more  beautiful  for  man's  needs  and 
enjoyment.  Let  us  not  be  unmindful  that  for  every  variuty  offered  by  the 
seedsman  and  grower,  in  many  instances,  yer-rs  of  painstaking  time  and  effort 
have  been  spent  in  developing  each  new  plant  to  its  nresent  state  of  perfection.

BAIvBOOS,  "^TTE  THEE  GRASSES. 
By  -  Robei't  A.  Yomig,  U.S.  Department  of  Agricultuie 
Bureau  of  Plant  Industry,  Division  of  Plant  Exploration 
and  Introdviction. 


We  usiially  think  of  trees  and  grasses  as  representing  plants  of 
oppo-iite  extremes  in  height,   There  are,  however,  several  distinct  groups  of  the 
large  family  of  grasses  that  contain  members  tall  enough  to  entitle  them' to  be 
called  trees  if  heigiju  alone  were  considered,  but  a  tree  should  be  woody,  have 
some  sort  of  branches,  and  be  capable  of  living  for  a  number  of  years.   In  the 
grass  family  it  is  only  in  the  group  called  bamhoor,  that  we  find  plants  that 
fulfill  all  these  conditions. 

Not  all  true  bamboos  are  of  tree  isi'ze  or  habit  of  growth.   Some  of  the 
smallest  grow  only  a  few  inches  high  and  are  really  grass-like  in  appearance. 
Bamboos  vary  greatly  in  size,  rangin,';;  from  v;/grnies  of  6  inches  to  super-giant? 
of  120  feet  in  height.  The  tallest  have  diameters  up  to  12  inches. 

More  than  UOO  different  specie!-,  of  bamboos  are  knovm.   They  are  fcJiid 
mostly  in  the  tropics  and  subtropics  but  there  are  hardy  kinds  that  thrive  in 
■'•he  milder  parts  of  the  temperate  zones.   Some  endure  temperatures  slightly 
below  zero  without  serious  injury.  All  of  them  do  best  in  a  reasonably  rich  a.iA 
'■'.oist  but  well-drained  soil.   The  valuable  ones  are  not  swamp  plants  and  will  not 
uhrive  in  poorly-drained  soil.  Nearly  all  bamboos  are  evergreen,  those  of  the 
■f'rnpcrate  zones  gradually  repl-Tcinr  their  old  leaves  with  new  ones  in  the  spring 
ar.d  early  summer. 

The  hardier  bamboos  are  mostly  natives  of  China  and  Japan,  and  these 
include  the  smallest  kinds  as  well  en'   some  tliat  attain  heights  of  60  to  80  feet. 
Two  are  native  to  the  southern  United  States.  These  are  the  canebrake  bamboo 
and  the  smaller-growing  switch-cane.   There  are  no  native  bamboos  in  Europe  and 
very  few  in  Africa,  Tropical  America  has  many  native  species,  but  by  far  the 
largest  nurnber  of  bamboos  are  native  to  soatheastern  Asia  and  the  Malay  Archipe- 
lago. 

TYPES  OF  BAlviBOOS. 


In  habit  of  ,;  rovjtn  bamboos  arc  of  t'vo  general  types:   clijmp-formiiig 
and  ininning.  There  are  ma..y  differin,^  groups  v/ithin  each  type  but  time  will  not 
permit  detailed  mention.   In  the  clump  bamboos  the  culms,  or  canes,  are  usually 
very  close  together,  because  tl'.c  bids  v;hic]i  sprout  from  the  base  of  the  plant 
beneath  the  surface  of  the  ground  almost  immediately  turn  upv/ard  to  form  a  new 
culm.  The  bamboos  of  this  type  growii  outside  the  tropics  send  up  their  new 
culms  in  midsiommer  or  later.  They  do  not  usually  extend  their  branches  until 
spring  ani  so  present  an  odd  appearance  during  the  vdnter. 


In  the  niniiing  t^.^e  of  baiiil'oo,  on  the  othor  hand,  there  are  horizontal 
i-'_ndergrouno.  stems,  or  rhisones,  which  of  ton  grow  several  feet  in  length  in  a 
season  and  it  is  from  these  rhizomes  that  the  vertical  culms  are  sent  up.  at 
irregular  intervals.   Culms  arising  from  one  of  these  horizontal  rhizomes  ma;-  he 
from  a  fe'./  inches  to  a  number  of  feet  apart.  The  rhizome  usually  ceases  direct 
lengthening  after  one  season  and  sends  out  numerous  side  branches,  ;vhich  in  turn 
later  send  up  vertical  shoots  to  fonn  new  culms;  thus  a  thicket  of  culms  develops 
ai.:d,  filially,  a  i^vove,   or  forest,  if  the  barJooo  be  of  gia.it  tyoo. 

All  the  hardiest  baxttboos  are  of  the  nnning  type  and  none  can  be  groi,vn 
in  clump  formation  or  other  small  area  without  artificially  confining  the 
rhizomes  or  continually  destroying  undesired  shoots.  The  nev;  culms  of  this  type 
of  bamboo  sprout  regularly  in  the  spring  and  so  have  opportunity  to  harden 
somewhat  before  cold  weather.   In  a  warm  region,  new  shoots  may  continue  to 
appear  until  raid-autumn.  The  miniraiom  area  in  which  a  running  bamboo  can  be  grovm 
to  its  greatest  height  depends  mainly  on  rh'^t  that  height  is.  Roughly,  the 
diameter  of  such  an  area  must  somewhat  exceed  the  hei;;ht  of  the  bamboo. 

The  length  of  tine  required  bj"  any  bamboo  to  produce  culms  of  maximum 
height,  after  being  started  from  a  sr.iall  plant,  will  again  depend  upon  what  the 
ultimate  height  is  and  also  on  the  soil  conditions  and  the  cultural  care  given,, 
Under  favorable  condition:',  ox  soil  and  moisture  some  of  the  raediuo-sized  banr:icos 
will  produce  culms  of  maxliaum  height  in  U  to  7  years,  while  larger  ones  reqiiire 
up  to  15  years  or  longer. 

Propagation  of  the  clurap  bamboos  is  commonly  effected  by  division  of 
the  clumps  or  by  the  rooting  of  stem  ciittinj^s  in  warm  wet  soil.  The  running 
bamboos  do  not  root  readily  from  stem  cuttings,  but  most  of  them  are  easily 
propagated  from  rhizome  cuttings  taken  in  late  sumraer  or  early  spring.   They  a:-e 
also  propagated  by  small  plants  with  pieces  of  rhizome  attached.  Most  bambooc 
flower  only  at  intervals  of  many  years  and  some  of  these  even  then  rarely  produce 
seed.  For  this  reason  we  must  in  general  resort  to  vegetative  propagation. 

The  seed,  or  fruit,  of  barrboos  varies  in  form  and  size  among  the 
different  groups  of  species.   In  most  types  it  bears  a  general  resemblance  to 
some  of  our  ordinary  cereals,  such  a,s  rye,  oats,  and  wheat.  One  of  the  rather 
large  bamboos  of  India,  however,  produces  a  peculiar-looking  fruit  U  inches  or 
more  long  and  nearly  3  inches  in  dia.aeter.   Samboo  seed  when  produced  in  qi^an^ity 
in  the  Orient  constitutes  an  importait  food  of  the  people. 

RATE  OF  CrTiOTI'Hi:   0"^  NI'-W  CULMS. 

The  bamboo  culm,  whether  large  or  small,  has  the  same  diameter  when  xt 
first  comes  above  the  surface  of  the  gro.md  that  it  does  when  fully  grown.   It 
is  a  most  interesting  sight  during  its  growth  in  heifrl;t,  especially  when  of  large 
size.  The  great  sheaths  which  at  first  envelop  the  culm  usually  soon  fall  off  or 
are  pushed  off  later  as  the  branches  develop.   In  some  groups  of  bamboos, 
however,  these  culm  sheaths  remain  attached  for  some  time.  The  sheaths  are 
characteristic  for  each  species,  and  by  closely  observing  their  markings  and 
external  structural  features  one  may  rather  easily  learn  to  identify  mary  of  the 
better-knovm  bamboo  specius  from  the  sheaths  alone.

complete  their  growth  in  H   to  ^  wecVjs  from  their  firf".t  appearar.ee  above  frr-)und. 
The  rate  of  I'^rowth  is  detemined  lrri;:ely  iDy  air  temperature  and  soil  moisture, 
The  daily  increa-se  in  height  varier  ■"'irectly  with  the  aii-  tei^perature ,  and  on 
a  very  chilly  day  growth  almost  ceases.  With  cufficient  moisture  and  higli 
tenpeiature ,  culms  3  to  5  inches  in  diameter  h^^ve  been  observed  to  f'row  as  mixch 
as  2h   to  36  inches  in  twenty-four  hours. 

The  hard,  relatively  durable  wood  of  the  timber  b?jiiboos  does  not 
become  f\xlly  mature  until  the  end  of  the  third  season  of  the  life  of  the  culm, 
but  the  culm  does  not  increase  in  aiiy  of  its  dimensions  or  chan^"e  its  general 
appearance  except  for  a  ,^rad\ial  fadiiv;  of  the  orif"inal  color,  lliilc  the  wood 
becomes  mature  in  3  years,  the  culns  usually  live  considerably  loni-rer.  Those 
of  the  hardy  {^is-^^t  ti--iber  bamboo  (phyllootachr'-G  reticulata)  are  knov/n  to  live 
for  12  or  more  years. 

BPJi:,iCHES  AifO  LEAViiS. 

The  branchinf;  of  bamboos  is  variable  in  different  croups  of  both  the 
clump  and  runninr  types  but  a  detailed  dircassion  would  be  of  interest  mainly 
to  the  spcdalist .   It  may  be  said,  hov/ever,  that  the  number  of  branches  at  a. 
node,  or  joint,  may  be  one,  two,  or  more.   In  some  conmion  clump  bamboos  there 
a.re  dense  tufts  of  20  or  more  branches,  mostly  rather  small.  Giant  culms  of  the 
running  type  often  are  v/ithout  branches  for  20  feet  or  more  above  the  £;rour:d„ 

The  leaves  of  bamboos  usually  are  borne  on  snail  braaichlets  arising 
from  the  branches.   Sometimes,  however,  the  branch  from  the  culm  bears  the 
],3aves  directly.  On  ordinary  branches  that  live  as  lonf  as  the  culm,  or  for 
several  years,  the  branchlets  usually  die  back  and  new  branchlets  with  leaves 
are  put  out  from  dormant  buds  near  the  bases  of  the  old  branchlets.  This  is 
repeated  each  year  until  the  culm,  or  the  branch  dies,  and  it  shows  how  bamboos 
are  able  to  live  for  a  number  of  years  'without  increasing  in  size.  The 
approachin;"  death  of  a  bamboo  culm  if-  indic^'.ted  by  the  dyin--;  first  of  the  topmost 
branches. 

Much  of  interest  could  be  said  concerninr:  the  leaves  of  some  of  the 
various  groups  of  bamboos  but  it  can  only  be  tcAiched  upon  here.  All  the  leaves 
are  parallel  veined,  but  there  is  one  practically  constant  difference  between 
the  leaves  of  the  clrjiip  bamboor  and  those  of  the  lunninn  type.  VJith  a  hand 
lens  there  are  easily  visible  very  numerous  cross  veins  in  the  leaves  of  nearly 
all  of  the  runiiing  bamboos,  w'iile  none  are  seen  in  the  leaves  of  the  clump 
bamboos.   Thus,  crosr-veininr  of  tlie  loaves  seems  to  be  associa.ted  with  hardirest 
in  bamboos. 

As  in  other  kinds  of  plants,  the  leaves  of  barrlcos  arc  extrem.ely 
variable  in  size  and  somewhat  so  in  shape.  One  Japanese  dwarf  species  has  an 
ovate  leaf,  which  does  not  suggest  in  form  £>.\y   ordinary  baiiboo  or  other  grass 
leaf.   Some  other  verjr  dwarf  species  have  leaves  up  to  a  foot  cr  more  loni"-;  ariC 
2  to  3  inches  wide.   On  the  other  ImrA,    the  largest  of  the  hardy  bamboos  of 
China  and  Japan,  v;hich  sometimes  tov/ers  to  a  heif'iht  of  SO  feet  or  more,  has 
adult  leaves  only  about  2-|  inches  long  "sy   a  quarter  of  an  inch  wide.

to  the  welfare  of  more  people  i;:  ihc   v;orl ',  thr..:  iny  othci-  single  (^roup  of 
plants.  To  hundreds  of  millif.jis  of  rjeople  tliroufhout  blie  Orient,  bamboos 
furnish  materials  for  shelter  and  other  structaral  p\irposcs,  for  food,  clothing, 
impleuentSj  utensils,  and  otiicr  necessary  and  useful  articles  almost  without 
end.  Bomboo  is  to  the  Orieht  what  other  vvuods  and  iron,  steel,  ani  copper  are 
to  this  country.   This,  of  course,  is  because  bamboos  always  have  been  easily 
available  there.  When  ve  have  .';rown  them  for  a  lonfrer  period  and  more  widely 
we  too  shall  doubtless  utilize  them  more  [generally. 

In  the  United  States  the  bamboos  thus  far  have  been  utilized  almost 
solely  for  their  ornajnental  value.  The  f^iant  clump  bamboos,  of  \7hich  five 
ppecies  are  at  present  fairly  well  Jrnown  in  southern  Florida,  are  of  value  for 
use  in  parks  and  on  rather  larfre  estates.  The  best  of  these  are  De .^drocalamus 
latif loriuj ,  {^vouiui'   to  about  Jj   feet  hijii,  axid.  a  smaller  Oiie  kncivn  by  the 
horticultural  name  Bambusa  thouarsii.  The  latter  attains  a  heif^t  of  UO  tc  50 
feet.  Tlaese  two  handsom.e  bamboos  v/ithstauu  temperatures  down  to  20  decrees  P., 
and  should  be  nrown  much  m.ore  gene.. '"lly  i:i  localities  that  do  not  e^q^erienco 
lower  temperatures. 

The  most  common  fiarit  ba;:i.-oo  in  southen.'  Florida  is  Bambusa  vul^caiis, 
a  very  tender  species  and  one  tliat  spreads  rat.ier  more  rapidly  than  any  other 
we  have  of  the  clump  type.   It  is  uufortur.'.tc  that  this  bamboo  should  have 
been  plaiited  so  widely,  and  ou,t  of  its  proper  cli''i.?.tic  ranr:e,  when  there  were 
better  ones. 

Wliat  is  probobl;.  the  tallest  bamboo  in  this  country  is  a  mafnificBni: 
clump  of  Bambusa  ar.iudina.'iea,  a  very  tiiorny  i.iant  bamboo,  on  the  shore  of 
Lake  Ariana,  in  Fol::  Cov.ity,  Florida.   Several  years  ago  this  v/as  estimated  to 
be  80  feet  high.   The  species  ir^  r  omewhat  i.  ore  ?.ardy  than  BTjiibusa_  vulgaris 
but  suffers  at  times  from  cold  ii,   central  Florida.  Dendr oc alaiaus  strictus  is 
a  non-thorny  giant  bamboo  of  abouu  eq-ua.!  hai. ;'.'ncs3.   It  should  be  planted  more 
in  localities  having  temperatures  not  lo'ver  t.,  an  about  2/  degrees  F. 

The  medium-sized  cli-vap  bamboos  gro\7n  througliout  Florida  and  Che 
northern  Gulf  region  are  horticultuz'al  varieties  of  one  species,  now  correci.ly 
called  Bajnbusa  multiplex.   The  Jiaincs  of  t}:ese  varieties  at  times  have  been 
erroneously  used  in  botanical  aiA  horticultural  literature  as  if  they  were 
true  botanical  names.   The  varieties  are  generally  known,  respectively-,  as 
follov.'s:   The  variety  Argentea,  with  plain  green  culms  and  leaves,  Argentea- 
striata,  ivith  green  culms,  and  part  of  leaves  striped  with  v/hite,  and  Alphcnse-- 
karri,  with  golden  culms  and  green  leaves.   This  variety  has  also  been  called 
i'-ipinbuFp,  verticill_at_a  in  Florirfa,   The  fourth  variety  ^.nd  ono.   of  the  best  ''cio't'i 
is  Disticha,  the  fern-leaved  form..   It  often  grotrs  as  a  dwarf  or  semi-dwai'f 
varietj'-  but  may  also  grow  20  feet  or  more  in  height.   It  often  reverts  in  part 
or  entirely  to  the  ordinary  type  of  foliage.  When  eiitirely  reverted  in  foliage 
tjrpe  the  variety  Disticha  practicallg  ceases  to  be  and  becor.es  indistinguish- 
able in  appearance  from  the  va.riety  Argentea.  The  latter  ;->ro oably  represents 
the  original  form  of  Bambusa  multi"plex.   T>ie  vn.rieties  .". rgcnt oa- s t r i ata ,

WHENCE  CAME  FLORIDA  GAIU.)E1I  PL/iOT'S? 

M,K.  Ensign,  asrociate  liorticulturist , 
Florida  Exoeriraent  Station. 


The  origin,  pe-ligi'ee  or  line  of  descent  of  individuals,  whether  man, 
plant  or  aaimal  is  a  s.io.^ect  of  considerable  fascination.   In  fact,  the  study  of 
genealogy  and  the  building  of  family  treec;  arao'ints  to  an  obsession  to  some  minip, . 
This  pastime  is,  of  coarse,  a  harmless  oiie  so  far  as  plants  are  concerned;  xor 
desperadoes,  feeble-minded  and  other  despicable  characters,  happily,  do  not 
exist  in  the  plant  world. 

So  far  as  I  am  personally  concerned,  the  ancestry  or  nationality  of  a 
plant  or  animal  (including  man)  is  really  of  very  minor  interest  or  consequence. 
The  thing  that  does  matter,  however,  is  hov/  the  individual  fits  into  the  present 
scheme  of  things  -  is  it  intrinsically  useful  or  beautiful  -  does  it  add  to  our 
pleasures  or  our  necessities'?  Obviously,  we  caimot  judge  the  need  for  ornament  ul 
garden  plants  except  from  the  aesthetic  point  of  view.   I  have  accumulated  a  few 
facts  regarding  the  history  of  the  origin  and  introduction  of  some  ornamentals 
commonly  found  in  Florida  gardens,  and  will  discuss  these  according  to  certa:.n 
groups! 

First,  the  rose:  When  a  trading  station  was  established  hy   an  English 
concern  known  as  the  East  India  Trading  Company,  in  Canton,  Southern  China, 
near  the  close  of  the  lyth  Centui^^,  no  one  would  have  gaessed  that  it  would 
have  had  such  a  profound  influence  upon  the  development  of  horticulture  in 
general,  and  upon  the  broadcasting  or  disseminating  of  the  rose  in  particular. 
Garden  and  pla,nt  enthusip,sts ,  therefore,  owe  'i  real  debt  of  gratitude  to  the 
pioneers  of  this  pxxrely  commercial  \ijiderta!''inf^  who  waged  an  extended  and 
difficult  straggle  to  maintain  a  foot-hold  in  China.  As  early  as  I696  some 
dried  specimens  of  the  rose  wore  sent  to  Exv'l^Jid  and  nearly  a  century  later 
living  plants  were  carried  by  company  offici'^ls  and  found  their  way  into 
private  gardens.  later  the  ;^.oyal  Gardens,  the  Kew  and  other  public  gardens 
acquired  such  plantr.  Tlr-esc  earl;''  roses  wera  the  China  Monthly,  Tea  and 
Rambler  roses  -  all  parei.'.ts  of  the  modern  rc.e. 

Early  in  the  ISth  Century,  roses  wero  introduced  into  India  from  the  same 

source  which  later  gave  rise  to  r,ome  confusion  since  they  were  regarded  as 

native  of  India  as  indicated  by  the  name  "Be-K-^-al  Rose",  really  a  synonym  for 
the  China  Monthly  Rose. 

Just  when  the  rose  was  first  introduced  into  America  does  not  appear 
with  certainty.  But  the  Cherokee  Rose  (another  China  Rose)  has  become 
naturalized  and  grows  wild  in  the  Southern  States.   In  fact,  Michau^:  in  I8O3 
firmly  believed  it  to  be  natit'e  to  this  country  and  named  it.(R,  l'X_vi.Gata^  ) 


Japan  has  also  coiitritn.-'  ed  a  muaoer  o£   rose  species  that  have  lormnd  the  basis 
for  'breeding  the  modern  roses. 

As  soon  as  these  plants  bc^4,ai'-i  arrivin;?^  iu  England,  they  attracted  tLn 
attention  of  botanists  and  patrons  of  horticnlture  so  that  men  were  dispatched 
to  the  Orient  to  find  novelties.  This  search  was  continued  not  only  bj^ 
En^lis^-iraen,  biit  plant  explorers  from  nearly  every  coiintry  have  searched  for 
desirable  plant  materials  that  have  in  many  instances  become  lasting  monuments 
tu  their  eiTorts.   So,  '^oday  ^.ui-  luoderu  ICillai-ncyo ,  Airiurioa.1  I-eau';,  ,  i.Ii"3.  'jh:.:. 
T^i.ssell,  La'iy  Hilliucdon,  Hainble-,  antt  others  are  hybrids  whose  ancestors  may 
yet   be  seen  in  the  raw  in  some  of  the  remote  parts  of  China  and  Japan.   It  it  of 
interci^t  to  laiow  that  only  those  ros  -s  indi,~enous  to  America  that  have  yellow 
flowers  have  been  utilized  in  the  breeding  program  of  rose  fanciers. 

The  origin  of  our  lilies  presents  a  simlar  story,  There  are  over  200 
different  species  of  lilies  and  to  nersly  recite  t?ieir  names  would  take  more 
time  than  I  am  allotted.  Sui'fice  it  to  say  that  some  of  the  finest  types  of 
lilies  have  come  from  the  Arid  Valle/s  of  Tibet  \7h0re  in  winter  it  is  excessively 
cold  and  in  summer  unbearably  hot  axid  dry.  Ot'iers  have  come  from  the  valley  of 
the  Yellow  River  of  China,  others  fror.i  Japau,  v/hile  mari^/'  are  found  native  to 
various  geographical  areas  of  the  Uniteil.  States.  Thus,  there  is  a  great 
variation  in  the  growing  conditions  ncccstinry   to  successful  lily  culture.  Exotic 
species  are  intolerant  to  ..lan-a-es,  cultivation  i..r  too  much  r.ioisture.   Tliey  gx-ovi 
best  among  herbs  or  low  shrubs.  'B'or  this  reaso -,  lilies  may  be  grouped  into  two 
classes:   (l)  Skvanp  lilies  including  moat  ox  those  native  to  America,  and  (2) 
iVry-land  lilies  v;hich  would  include  most  of  those  common  to  Japan  and  China, 
■"'here  are  two  kinds  that  have  becoL.e  comi-iercially  important  in  Florida,  namely, 
■'",he  Narcissus  and  the  Hybrid  Ai'iaryllis. 

Trom  whence  came  the  chrysanthe^^r.ls?  The  earliest  and  basic  varieties 
came  mostly  from  China  through  the  same  avenues  that  the  rose  was  introduced, 
although  the  Alps,  Morocco,  Dal;-;atia,  Persia  and  even  the  Arctic  regions  in 
[Liberia  have  contributed  to  our  modern  assortments.   The  number  of  species  of 
chrysanthemums  is  large,  and  from  them  plant  breeders  have  developed  hundreds  of 
varieties  that  show  wide  variations  in  size,  color  and  adaptability.  By 
exercising  some  care,  fine  specimens  can  be  grown  in  Florida  during  the  late 
summer  a,nd  fall. 

'A'e  also  should  mention' the  azalea.  As  "-\ere  ur^lerstood  the  group  Rhododcjdron 
includes  all  of  the  azaleas,  although  gardeners  habitually  separate  then.  A 
surprisingly  large  number  of  azaleas  ..ave  come  from  China,  the  Himalaya  Mounta'rS; 
and  some  from  the  Caucasian  Hic'.;lT.lan'''-S.  There  are  many  species  native  to  America, 
both  in  the  warmer  regions  of  the  South  an'l  th-;  more  ble-'".:  areas  of  the  Kocky 
Ko-'ontains  and  Labrador.  Most  of  thc-e  comir.on  to  Florida  gardens  are  native  to 
ths  South. 

Among  the  shrubs  of  partic-ilar  interest,  the  Fep].'er  Bush  ( Cl_ethra) ma.y  bo 
mentioned.   It  blossoms  from  mid-July  on  d-urin,;-  the  svu-iraer  anl  has  the  advantage 
,  of  being  a  native  of  Florida,  At  least  one  of  the  species  also  may  be  found 
along  the  coast  in  swp^rpy  places  as  far  north  as  Maine. 


Turning  to  the  vi:ies  \7e  find  Ghat  many  coinnon  and.  desirable  kinds  cane  from 
lax-away  coantries.   Vines  loni'i;  ajjo  proved  biieir  attractiveness  to  nan, 
oq-^ecially  the  proverbial  cli?v^inf:  Linds,  an'  there,  are  some  rare  specinci.s  in 
Florida.  Tlo  colorful  Biniionias  arc  sone  cf  the  best  laiovn.  Some  of  these  are 
native  to  Florid.a,  while  others  have  ecn   introlu'-.ed  from  Brazil  and  the 
.Argentine.  The  BouHainviller^.s  are  no  Icjs  attractive  and  likewise  sone  of  them 
cone  from  a  nunher  of  South  /ii.ierican  couiitrios,  v.hile  others  are  native.  All  of 
then  are  easily  i,T0vm  for  they  are  adapted  to  Florida  f^rowinf  conditicns. 

We  do  not  knov/  who  first  hrou^ht  Cle:.ia,tis  from  Japan,  nor  the  so-called. 
Bag  Flower  or  Glory  Bo'ver  from  Africp.   To  v/honcvor  it  was  we  are  ^Tateful. 

^Tlien  we  cone  to  the  hcney=!iickles  we  find  three  well-known  kinds.  The  Coral 
Honeysuckle,  or  T/o oddu i".e ,  io  a  native  cf  Florila;  the  Cape  Honeysuckle  as  the 
name  iiTplies  oriF:inatod  in  South  Africa,  while  a  third  species  was  introduced 
from  China  or  Japaii.  The  ;''aEGion  Flower,  probaMy  a  sequel  to  the  Clinf^inc  Vine, 
is  a  nift  from  Brazil,  while  V.:c   oi.ila::  is  .-;  cr:  •  d -/  fou-id  in  Florida  and  trop'^cal 
Ar.ierica.  The  most  comi.-;on  spL,cios  of  "'isteria  cfinic  originally  from  China.  Tho 
more  important  annuals  have  cone  to  us  from  a  v'ide  variety  of  sources.   It  may 
he  easier  to  follow  if  those  arc  ,Triiupcd  accordint:;  to  the  country  or  re.'^ion  in 
which  they  were  originally  found. 

The  Argentine  produced  the  Petu:da  and  LIari.:;old,  the  latter  is  also  found. 
in  Mexico  and  many  of  the  other  Soiith  /jncrican  countries.  From  California  the 
Poppy,  Lupine  and  Larkspur  have  haen  ■broadcast.  The  two  latter  are  also  found  in 
nany  of  the  'Testern  s,nd  Rocliy  I'oruitain  State:'..   China  gave  us  the  Larkspur, 
■:'hinese  For.~;ut-me-not  and  Baby's  breatli.  Tho  latter  is  also  found  in  Europe, 
iVorth  Africa  and  in  the  Himalaya  Mountains.  Brazil  was  the  home  of  the  Mosg  Rase ^ 
and  Morning  Glory.  The  latter  is  foun.i  quite  generally  also  in  tropical  America. 

The  Corn  Flower  came  from  Southeastern  Eiorope  in  the  vicinity  of  the 
Pyrenees,  Sicily  and  east  to  Persia.  Lapi.ni,:-  are  also  cannon  to  the  Mediterranean 
area.  Pinks  are  scattered  from  Russia,  PirJand  and  Deamark  on  the  north  to 
France,  Italy  and  E^ypt  on  the  south.   Snf!V''.ra;';onf,  arc  also  natives  of  the 
Mediterranean  region.   They  were  brought  to  America  at  an  early  date  and  escaped 
from  cultivation  in  the  eastern  part  of  tl  e  United  otatcB  where  they  have  become 
common  wild  flowers.   The  Sweet  Pea  is  a  native  of  Italy,  also  is  the  Candytuft. 
Our  Stocks  come  from  Southern  Europe,  while  the  Margue.rite  Carnation  emanated, 
from  Denmark,  Rinsia,  Eu'"iania  and  as  far  cast  as  Greece. 

To  Mexico  we  are  indebted  for  Agci'at-om.,  "innias  r.nZ   the  Nasturtium.   In 
North  America,  which  is  a  v.:ry  large  area,  orifinr'ted  some  cf  the  more  comimon 
tilings  grown  in  merit  g'l.rdenr?.  Ue  nig]it  ncntio.i  Surif lowers.  Verbena,  Phlox,  and 
some  species  of  Corn  Flower,  L-\pin.;S  and  Lark^.-y-rs.  Of  the  100  or  more  species  of 
Verbena  all  but  one  are  native  to  ll^rth  Ar.icrica. 

South  Africa  yielded  the  St rawf lower  and  the  Lobelia.  The  well-known 
Calendula  originated  in  the  Canary  Islands  and  east  to  Persia,  while  the  Florists, 
Paint  Brush  cones  from  the  tro;"ics  of  the  01"''-  "orld.

ZEPHYMl'ITHES  —  FLOTORS  OF  THE  WEST  WIl®, 
H.  Harold  Hiime,  Assistant  Director, 
Research,  Florida  Experiment  Station 

Zephyranthes,  (Zeph-yr-an'-thes)  derived  from  two  Greek  words  —  Zephyros  , 
the  west  wind,  and  anthos,  a  flower;  therefore  meaning  literally  "Flower  of  the 
West  Wind"  —  is  the  name  given  by  Dean  William  Herbert  in  1S21  to  a  lovely  group 
of  bulbotis  plants  found  in  the  southern  United  States,  in  the  West  Indies,  Mexico 
and  parts  of  South  America,  Mature  plants  consist  of  a  bulb,  a  few  leaves, 
narrow  or  strap-sha.ped,  gray-green  or  bright  green,  with  flowers  white,  pink,  red, 
cream,  yellow  or  copper-colored,  according  to  variety  or  species.  They  are  borne 
singly  on  stems  usually  varying  in  length  from  six  to  twelve  inches.  The  flower 
habits  of  different  Zephyranthes  species  differ  materially.   In  one  group  they 
open  quite  flat;  in  another  the  petals  are  bent  back  at  the  tips,  lily-like; 
while  in  still  another  group  the  petals  do  not  open  widely,  but  remain  rather 
upright  like  those  of  a  crocus.  The  spread  of  the  petals  in  some  instances  appears 
to  be  influenced  by  light  and  peihaps  by  temperature  and  hiimidity.  Several  common 
names,  most  of  them  based  upon  peculiarities  in  their  flowering  habits,  are  given 
bo  them.   In  some  parts  they  are  known  as  rain  lilies,  in  others  they  are  called 
Easter  lilies,  in  other  sections  they  are  fairy  lilies.   In  India  they  are  known 
as  Thunde r  Flowers,  while  in  Chin?,  one  species  is  referred  to  as  the  grass  lily. 
From  gardening  literature  here  and  there  the  name  Zephy  lilies  can  be  added.  These 
common  names  relate  to  time  of  flowering,  the  character  of  the  foliage,  the 
scientific  name,  to  the  dainty  beauty  of  the  flowers  and  to  their  interesting 
habit  of  coming  into  bloom  very  quickly  under  certain  conditions.   It  is  probably 
most  fitting  that  the  name  Zephyr  flowers  be  adopted  as  a  common  English  name. 

Perhaps  no  garden  plants  are  more  easily  grown  than  these.   They  are  suited  to 
our  soil  and.  climate  and  may  be  grown  throughout  all  Florida.  Bulbs  adapted  to 
given  conditions  in  suitable  aren.s  are  comrnonlj'  easy  to  handle,  but  the  Zephyranthes 
surpass  many  other  bulbs  in  requiring  so  little  care  and  attention  and  giving  much 
of  dainty  beauty  in  return.  Since  most  gardeners  are  looking  for  plants  that  are 
easy  to  grow,  they  should  be  much  more  connion  in  Florida  gardens  than  they  now 
are.   It  is  true  the  flowers  are  not  long  lived,  two  days  or  so  at  most,  but  it 
may  be  that  because  their  beauty  is  so  fleeting  they  are  all  the  more  interesting 
and  desirable.  *■ 

Florida  has  three  species  of  Zephyranthes  native  within  her  borders.  These 
are  Zephyranthes  Atamasco  (At-am-as'-co) ,  Zephyranthes  Treat iae  (Treat '-i-e)  and 
Zcyhyranthes  Simps onii.  (Siirp'-soii-i)  Tlie  first,  Zephyranthes  Atamsco,  is  found  in 
v.v£t  Florida  and  is  fairly  common  along  the  banks  of  the  Apalachicola. 
1  rphyranthes  Treat  iae,  named  for  Mrs.  Mar;;,'-  Treat  who  collected  it  near  Green  Cove 
Springs,  is  quite  common  in  the  northern  and  northeastern  parts  of  Florida, 
although  it  extends  well  down  the  state  as  well,  while  Zephyranthes  Simps onii  is 
native  far  south  in  the  state.  All  bloom  early  in  spring,  sometimes  in  autumn  as 
well,  and  all  have  piiic  or  reddish  colored  flower  buds,  though  the  flowers  are

white  when  open.  The  pink  coloring  is  confined,  as  a  rule,  to  the  three  outer 
parts  of  the  perianth.  Most  of  the  flowers  fade  away  with  a  pink  tint.  The 
flowers  of  Zephyranthes  Atamasco  and  Zephyranthe s  Treat iae  open  wide  like  those 
of  a  lily,  while  those  of  Zephyranthes  Simpsonii  are  crocus-like.  This  last  is 
one  of  the  finest  of  the  white  species,  and  as  many  as  four  flowers  have  been 
noted  from  a  single  bulb  at  one  time. 

Over  on  the  other  side  of  the  &ulf  of  Mexico  four  other  Zephyranthes,  by 
name,  Zephyranthes  longifolia,  (long-if-ol'-i-a) ,  Zephyranthes  pulchella, 
(pul-chel'-la)  Zephyranthes  Texana ,  (Tex-a'-na)  and  Zephyranthes  chrysantha 
(chry-santh'-a)  are  to  be  found.  All  of  them  are  native  in  parts  of  Texas,  though 
some  are  knovm  to  extend  beyond  the  boundaries  of  that  state.  Of  this  group  the 
one  most  common  in  cultivation  is  Zephyranthes  Texana  and  it  is  a  particularly 
lovely  plant.  The  flowers  are  a  deep  golden  color  within,  shaded  on  the  outside 
with  copper  and  reddish  copper.  The  flowers  are  small,  borne  on  Slendfit  scapes 
and  do  not  open  widely.  Good  bulbs  produce  several  sets  of  flowers  during  the 
summer  season. 

Here  and  there  in  Florida  gardens,  not  nearly  so  common  as  they  should  be, 
three  introduced  species  are  to  be  found.  These  are  Zephyranthes  carinata, 
(car-i-na'-ta)  from  Mexico,  Zephyranthes  rosea  (ro-se-a)  from  Cuba  and  other 
islands  of  the  West  Indies,  and  Zephyranthes  Candida  (can'-did-a)  from  the 
Argentine.  Of  these  the  first,  Zephyranthes  carina.ta,  is  probably  the  most  common. 
It  has  large  flowers,  opening  quite  flat,  three  to  fovir  inches  across,  dark  pink 
when  they  open  first,  changing  to  a  much  lighter  shade  as  they  fade.  The  flowers 
of  Zephyranthes  rosea  are  much  smaller,  a  bright,  sprightly  pink,  darker  than  in 
Zephyranthes  carinata,  and' the  color  becomes  darker  as  they  fade.  The  leaves  are 
bright  green,  strap-shaped,  blunt  pointed,  and  lie  quite  flat  upon  the  ground. 
It  is  one  of  the  daintiest  and  loveliest  of  all  the  group.   It  is  native  in  Cuba. 
i       Zephyranthes  Candida  is  an  interesting  species  with  upright  rush-like  leaves  and 
'   white  flowers.   It  is  stated  that  the  Rio  de  La  Plata,  the  Silver  River,  was  so 
named  by  the  Spaniards  when  they  sailed  up  it  because  of  the  profusion  of 
glistening  white  flowers  of  Zephyranthes  Candida  along  its  marshy  banks,  and 
perhaps  the  name  of  the  Republic  of  Argentina,  through  which  this  river  flows, 
traces  back  to  this  same  delightful  plant,  because  the  word  "Argentina"  also  means 
silvery  or  silver.'  Zephyranthes  carinata  flowers  in  northern  Florida  during  the 
latter  part  of  May,  with  a  wonderful  flush  of  bloom,  and  this  is  followed  by 
scattering  flowers  throughout  the  rest  of  the  season  into  October.  Zephyranthes 
rosea  blooms  in  late  August.  Zephyranthes  Candida  also  comes  late  in  the  season 
and  continues  to  flower  in  autumn  and  though  it  sometimes  does  not  bloom  profusely, 
it  is  a  very  desirable  sort. 

Other  kinds  of  Zephyranthes,  so  scarce  that  they  are  seldom  seen,  are 
Zephyranthes  citrina, (cit-ri-na)  Zaphyranthes  robusta,  (ro-bus'-ta)  Zephyranthes 
Ajax,  (A'-jax)  and  Zephyranthes  tubispatha  (tub-is'-path-a) .   All  are  particularly 
fine.  Zephyranthes  citrina  bears  deep  yellow,  almost  golden  flowers  on  eight  or 
ten  inch  stems  and  blooms  several  times  during  the  summer.   Zephyranthes  A.jax  is  a 
hybrid  between  Zephyranthes  citrina  and  Zephyranthes  Candida.   Its  upright  leaves 
resemble  those  of  Zephyranthes  Candida  in  habit  and  its  flowers  are  light  yellow. 
Its  blooming  habit  is  that  of  Zephyranthes  citrina.   It  is  a  good  variety. 
Zephyranthes  tubispatha  is  a  white  flowered  species.  The  flov/ers  are  green  at  the 
base  and  they  do  not  open  widely.   It  is  one  of  the  finest  whites,  though  not  so 
free  in  flowering  as  Zephyranthes  Simpsonii.

The  propagation  of  Zepliyranthes  is  acconrplishcd  either  from  t5eed  or  by  offsets 
or  small  bulbs  developed  from  the  bases  of  old  b\ilbs.  Seeds  are  not  produced 
freely  from  all  sorts.  So  far  as  I  have  observed  Zcphyranthc-s  carinata  does  not 
produce  seed  in  Florida  and  apparently  this  ie  its  behavior  in  many  other  places. 
In  one  instance,  however,  it  has  been  reported  as  formin":;  seed.  Likev/ise, 
Zepliyranthes  Candida,  under  Florida  conditions  usually  does  not  produce  seed.  On 
the  other  hand,  Zephyranthes  rosea,  Zephyranthes  tub  i  spat  ha,  Zephyr  an  the  s  A.j  ax , 
Zephyrpjithes  robust a,  Zephyranthes  citrina,  Zephyranthes  Simpsonii,  Zephyranthes 
Atamasco  and  Zephyranthes  Treat iae  all  produce  seeds,  most  of  them  quite  freely. 
Seeds  germinate  readily  and  bulbs  are  quite  easily  grovrn.  A  pood  mixture  for 
planting  seeds  is  one  composed  of  good  building  sand  and  peat,  one-half  each  by 
bulk,  or  screened  '.voods  mold  alone  may  be  used. 

In  the  production  of  offsets  the  different  species  of  Zephyranthes  also  vary 
considerably.  Tliej'-  are  produced  freely  by  Zephyranthes  Candida,  Zephyranthes 
tubispatha,  Zephyranthes  A;j ax ,  Zephyranthes  rosea,  and  in  certain  instances  by 
Zephyranthes  Atamasco.   They  are  produced  less  f reelj'-  by  Zephyranthes  carinata  and 
Zephyranthes  robust a,  and  are  seldom  seen  in  Zephyranthes  Treat iae,  Zephyranthes 
Texana  a.nd  Z ephyranthe s  citrina.  The  offsets  may  be  separated  '.vhen  quite  small  and 
established  as  independent  plants. 

As  already  indicated,  the  culture  of  the  various  kinds  of  Zephyranthes  is 
comparatively  simple.  This,  hov/ever,  does  not  mean  thp.t  they  should  not  receive 
some  care  and  attention.  The  best  in  any  plant  or  in  any  garden  cannot  be  had 
without  putting  something  into  it,  something  of  thougiit ,  of  planning,  of  food,  of 
water,  of  care  and  attention.  More  flowers,  more  bloom,  more  interest  and  more  joy 
are  the  rewards  of  loving  care.  Let  Z e"'hyanthe s  have  some  of  these  things  and  the 
rev/ard  will  be  greater.  On  the  whole,  best  results  are  secured  by  planting  bulbs 
of  this  group  in  a  sandy  los-m,  well  supplied  with  vegetable  matter  obtained  from 
peat  or  woods  mold.  Well  rotted  dairy  fertilizer  can  be  added,  but  it  is  best  to 
use  it  as  a  surface  dressing  and  not  incorporate  it  with  the  soil.  Commercial 
fertilizer  such  as  one  v.'ould  use  in  growing  white  or  Irish  potatoes  gives  very 
satisfactory  results  as  a  source  of  plant  food.   Two  applications  yearly  will 
suffice.  VTater,  too,  they  n?j.st  have.   It  is  true  that  bulbous  plants,  because  of 
their  storage  facilities,  do  not  show  distress  from  a  shortn/-e  of  water  so  quickly 
as  do  many  other  plants,  but  if  too  little  is  furnished  their  growth  and  flowering 
will  be  reduced  ultimately.  Zephyranthes  Candida  is  a  swamp  S'^ecies;  our  native 
Zephyranthes  Treatiae  and  Zephyranthes  Sim-Qsonii  grow  in  the  flat  woods  that  are 
usually  moist  at  certain  seasons  and  these  three  respond  to  copious  waterings. 
Indeed,  apparently  none  of  them  but  that  appear  to  be  greatly  benefitted  by  goodly 
supplies  of  moisture  at  all  tines.   In  those  sections  where  bxilbs  pass  through  the 
winter  season  uninjured  by  cold,  as  in  all  parts  of  Florida,  they  may  be  planted  at 
any  time  of  year.   In  the  bazaars  of  India,  the  stored  bulbs  of  Zephyranthes 
carinata  are  sold,  guaranteed  to  bloom  v;ithin  three  weeks  after  planting.   If  this 
be  true,  by  taking  up  bulbs  from  time  to  time  and  keeping  a  supply  on  hand  it  might 
be  possible  to  force  them  and  so  bring  them  into  flower  at  will.   It  would  be 
worth  trying  though  I  have  never  done  so. 

Zephyranthes  bulbs  should  be  planted  quite  close  together  and  in  considerable 
numbers.  A  single  bulb  here  and  there  falls  far  short  of  the  effect  that  may  be 


i... 


secured  with  numbers  planted  together.   Nothing-  can  surpasc  in  their  fresh 
"beauty  a  nass  plantin^^:  of  Zephyranthes,  of  c^rinata,  rosea  or  citrinn,  for 
instance.   Tlie  interestin,":  part  of  it  is  that  all  these  bulbs  will  come  into 
flower  together,  a  burst  of  bloom  not  possible  \7ith  many  kinds  of  plants.   They 
may  be  used  alonf-  the  ed,-o  of  the  shrubbery  or  perennial  border,  they  may  be 
planted  in  groups  of  a  dozen  or  more  here  and  there  alonf  the  ed;';es,  or  they  may 
be  e-iven  a  section  of  the  border.   They  are  also  used  for  nlantili.-  alon-i  the 
edces  of  walks.  Planted  close  to.-ether  the  folia,-:e  of  many' of  them,  Zephyranthes 
Candida,  rosea,  tubispatha,  A.jax  and  Atanasco,  for  instance,  covers  the  soil 
;vell  and  so  serves  as  a  ^rround  cover. 

It  is  said  that  when  Lord  Kitchener  \7as  resident  at  Simla  in  India, 
Ze-phyranthes  carinata  was  frequently  used  as  a  table  decoration  and  certainly 
when  placed  in  suitable  vases  or  holders  this  species  and  others  are  very  fine 
and  dainty  as  cut  flowers.  Tliey  should  be  gathered  just  as  they  open  and  used 
in  the  house  for  that  day  only.

FLOIlID.A.'S  ITATIVE  FLOORS, 
3y  -  Erdraan  "^est,  mycologist, 
Florida  Experiment  Station 


opring  is  herel   Tne  season  wlieii  i'lorida  sunsliine  seems  particular I7 
"benevolent.  The  birds  are  singing  gsyly  and  gardeners  are  digging,  ra.king  and 
planting.  Flower  beds  are  being  planned  or  revised,  llurssry  and  seed  catalogs 
are  being  searched  carefailly  for  attractive  plants  and  flowers.  Aiid  oi;t  in  r,he 
woods  and  the  fields  and  the  marshes,  old  ;:other  ITature  is  quietly  beginning 
another  twelve  months'  display  of  Florida's  wild  flowers. 

"But",  someone  remarks,  "you  cnn't  grow  wild  flo'.vers  in  your  garden.  They 
just  won't  grow."   And  another,  a  devotee  of  roses  aid  ca-rnrtions,  says;  "Yihyl 
they  are  only  weeds.   You  wouldn't  expect  me  to  plant  such  trash  nea.r  my  rose 
garden,  would  you^"  And  the  ansv/er  to  those  objectio'.:s  is  tliis:   Give  our  r.ative 
plants  a  situation  comparable  to  their  native  h-^bita-t  and  a  background  suitable 
to  their  color  and  form  and  you  will  find  Florida's  native  flowers  just  as 
amenable  to  garden  conditions  and  just  as  attractive  as  many  of  our  cultivated 
plants. 

Let  us  see  what  n^  tive  plants  we  may  find  suitable  for  our  gardens.   As 
many  native  shrubs  and  trees  have  been  used  frequently  in  the  la.ndscaping  of 
Florida  homes,  we  will  consider  chiefly  herbaceous  plants  in  this  discussion.   If 
wc  consider  these  in  groups  arranged  accorc'inf''  to  the  use  or  situation  for  v/hich 
they  a.re  intended,  it  will  make  our  labors  still  easier. 

Perhaps  the  easiest  ^roup  of  all  -  from  the  cultural  standpoint  -  is  the 
vines.  There  arc  a  ntanber  of  native  Florida  vines  tlia.t  ma,]:e  excellent  cover 
material  for  fences,  arbors,  trellises  or  pergolas.   I  am  sure  that  you  have  sef:; 
and  admired  yellov.-  jessamine  in  the  v.-oods  in  the  Spring.  Have  you  ever  thou^t 
jf  it  in  the  garden  as  a  cultivated  vine^  Strong  roots  are  easily  obta.inod  a.rid 
t,.ow  readily  under  a  wide  range  of  conditions.  The  plant  is  a  rapid  grower  ".nd 
.""■'ponds  to  good  treatment  includin,<5  fertilizer.   If  you  plajat  it  where  it  get^i 
.full  sunshine,  it  will  bear  a  solid  mass  of  deliciously  sweet-scented  flowers 
in  i.Iarch.   The  remainder  of  the  year  it  supplies  a  graceful  evergreen  bl-ankei.-  of 
loaves.   Its  only  bad  habit  is  its  tendency  to  spread  over  the  surface  of  the 
ground  from  its  base.  However,  the^e  lonf  r^onners  are  easily  persuaded  to  clii'i^. 
If  you  want  to  restrain  its  activities,  it  can  be  cut  back  severely  at  any  time, 
but  if  you  wish  flowers  in  Spring,  do  your  pruniniT;  in  early  summer. 

Another  nearly  evergreen  vine,  that  is  very  a.ttractive  is  the  \70odbine, 
Lonicera  sempervirens  (lon-i-ce'-ra  sem-per-vi'-rens) =   In  its  natrral  habitat, 
it  is  seldom  an  attra-ctive  object;  but  put  in  good  soil  with  a  moderate  supply 
of  fertilizer  and  moisture,  it  will  soon  cover  a  trellis  with  a  \erdprit  blanket 


of  a  peculiar  yet  plepsir.g  blue-green  ti.it.  All  during;  the  Sprint'::  and  early 
S'ommer,  the  ends  of  the  t;racefully  protradir.;;  branches  bear  clusters  of  oran,:;e-red 
ixuv/ers  very  attractive  to  oatteri'lies  and  hiomminG  bircLG,  as  v.-ell  as  the  hvun:':.u 
eye,   Au'-l  this  is  not  all,  the  flovern  are  follov:cd  by  cluGtors  of  brii-"ht  red. 
translucent  berries. 


Another  perennial  vine  with  orange-red  flowers  is  the  cross-vine  (Bigionia 
crucifiera)  a  relative  of  oxir  exotic  3i~norias.   It  is  useful  in  covering  a  wooden 
arbor  or  trellis,  but  is  loss  attractive  than  the  foregoinf;  plants. 

There  are  several  other  clinibi^rr.  thp.t  cm  be  used  in  suitable  positions,  Tlie 
Carolina  aster  (Aster  carol inianus)  thrives  under  cn.ltivation  a:id  v/ill  clamber 
over  low  v/alls  and  trcsslises.   If  care  is  talon  to  obtain  large  flowered  tyocs, 
very  attractive  results  co,n  be  obtained. 

Two  closely  related  vi:.es,  Clcinatic  (Clera' -^.-tis)  and  Viorna,  (Vi-or'-na) 
furnish  a  very  light  feaf...  ry  cover  for  a  pcrr.^ol-'  or  arbor.  The  Virona' s  have 
purplish,  leathery,  pendant  flov.'ers  in  ?uin  .or,  w:  ile  the  Clematis  has  a  mass  of 
fragrant  white  blossoms  in  early  ?all. 

The  moon-flower  is  so  widely  grcv/n  that  iaof:t  folhs  have  forgotten  that  ii;  is 
a,  native  vine. 

The  passion-vine  or  may-pop  (fassiflora  incarnata)  ,  a  weed  in  some  sectiGr^s, 
c-'-n   be  used  to  advantage  as  a  cover  for  fences  in  the  summer. 

Before  we  leave  the  subject  of  vi:ies,  let  us  not  forget  a  spot  of  color 
fo;.-  Winter!,   Suiilax  ".Talteri  bears  multitudes  of  red,  holly-like  berries  in  Fall 
and  ^Yinter,  pjid  is  especially  attractive  when  used  with  a  decidiaous  vine  such  as 
iUr'-staria. 

Nqw,  how  about  a  few  of  Florida's  ovm  flowers  for  the  rerTilar  flower  garden? 
Woct  of  the  plants  that  I  have  selected  are  hardy  perennials  that  have  been  tried 
and  found  useable.  Several  of  these  are  anong  the  compositen.  There  are  several 
species  of  blazing  star  or  Liatris  (Li-a'-trls)  that  do  v;ell  and  create  a 
different  atmosphere  in  the  garden  v;ith  their  tall  spihcs  of  rose-parple  flowers. 
Just  one  suggestion  when  growing  them  in  good  garden  s.vil  ••  the  spikes  grow  so  ta_ 
and  vigorous  that  they  can  seldom  hoi'',  up  tix-ir  own  weight.  They  need  support  in 
the  way  of  stakes. 

Another  hardy  perennial  that  offers  great  possibilities  is  the  native  svu- 
f"-ower.   Several  species  have  very  attractive  :  ellow  flowers  an",  produce  them  m 
Qx'^.B.t   profusion.   Thoy  succeed  in  almost  any  soil  provided  they  have  full  sun- 
shine. They  can  be  propagated  by  uiidc rgroimd  rinners,  dividing  the  crowns,  or 
from  seed.  Good  selections  shnul'".  be  Lraltiplie '  ve'.'ctatively,  so  that  the 
desirable  characters  may  not  be  lost. 

Closely  related  to  the  s\inf lowers  are  the  bla.cl;-eyed  susans  or  Rudbeckias, 
(i:ud-beck'-ias)  most  of  which  are  annuals  or  jjoi'ennials.  These  plants  reproduce 
readily  from  seed  and  several  of  the  species  produce  a  profusion  of  yellow 
flowers  with  brown  centers. 


-3- 


Several  of  the  goldeurocls  have  attractive  flower  cliisters  and  are  nice 
enough  to  put  in  the  garden,  Thc^  shov.'  up  best,  however,  anouf;  the  shrabbery  or 
along  a  fence. 

One  shrubby  composite,  Q-arberia  fraticosa,  (Gar-be'  rca  frat-ic-o'-sa)  makes 
a  lo'.v,  dense  nmss  of  gray-green  foliage.   In  Fall  the  plants  are  topped  with  a 
crorm  of  the  small  pinl:ish  flo'vers. 

The  woods  will  soon  be  splotched  with  the  cardinal  red  spikes  of  the  Cherokee 
bean  (Erythrir-a  herbacea) .  Tliene  dazzling  spires  grow  from  a  large  tuberous 
root  that  transplants  readily  to  the  garden.  After  the  flov;ers,  the  green  bean- 
like leaves  appear  on  spiny  stems  aiid  by  mid-sui;ir.ier  the  long  pods  burst  open 
disclosing  the  bright  red  beans. 

There  are  three  species  of  native  lupines  in  Florida  that  have  blue  or 
bluish  flov/ers.  One  of  these,  Lupinus  pcrennis,   (Lnp-i-nus  per-en'-nis)  is 
well-loiown  in  gardens,  especially  further  north,  but  our  own  species  ;vith 
unifoliate,  fuzzy,  gray-green  leaves  are  loss  well  kmwn.  None  of  these  hardy 
lupines  will  transplant  after  they  have  passed  the  seedling  stage.  The  seeds 
germinate  readily,  however,  if  they  are  nicked  or  scarified  before  planting.  Ihj 
masses  of  flov-ers  produced  by  these  pl'cits  repay  a  little  extra  trotible  in  gr^^^dng 
them. 

There  are  many  other  plants  r,iiioh  nay  be  brought  into  the  garden.  Amorg 
Lhese  are  the  v;hite-f lowered  false  indigo,  (Baptisia  leucantha ) ;  the  poppy  mallow, 
(Callirrhoe  involucrata)  with  brillisnt  roci3-red  flowers;  Gilia  i-ubra  and  Lobelia 
>:ardinalis  (Lo-be'-lia  car-din-a'-lis)  both  with  spikes  of  bright  red  flov/ers; 
v.he  orange  butterfly  millc.7eed,  (Asclepir.s  tuberosa) ;  and  the  native  sages,  Salvia 
lyrata  (ly]>-a'-ta)  with  blue  flov.'ers  and  Salvia  coccinea  (coc-cin-e'-a)  with  red 
flowers. 

'Jith  the  great  increase  in  the  interest  in  tropical  fish  and  aquaria  in  general, 
several  of  Florida's  water  plants  have  cone  i'lto  great  demand.  The  strange- 
appearing  water  lettuce  (Fistia  stratiotes)  is  often  used  on  the  larger  of  these. 
For  submerged  plants,  Flori..a  furnishes  Cabomb-i.,  '."ebsteria,  Ludwigiantha , 
(Lud-wig^i-an'-tha)  Potonogeton  (Po-to;->-o-te'-ton)  ,  Valisneria  (Val-is-ne'-ri-a) 
and  certain  species  of  Sagittaria. 

Lily  pools  and  v/ater  gardens  and  popular,  too.  For  these  Florida  supplies 
two  excellent  water  lilies  including  the  fine,  yellow  ones  Castalia  flava 
(Cas-tal-ea) . 

Another  famous  water  plant  is  Florida's  native  yellow  Lotus.  This  has  a 
...est  peculiar  distribution  in  the  State  ap-vearing  in  scattered  and  unconnected 
l;Jces.   Some  of  these  have  been  drained  d.uring  the  past  few  dry  years  and  the 
nlant  undoubted.ly  has  been  killed  out  in  tJese  locations.   In  favorable  situation'- 
it  spreads  rapidly  by  under-v.-ater  rhizomes  and  nay  be  hard  to  control.  The  gruat 
pale  yellow  flov/ers  are  beautiful  and  these  are  follovved  by  the  decorative  seed 
pods.  The  hard-shelled  seeds,  knov/n  as  water  chinquapins,  do  3:iot  geminate 
-•eadily.  Sections  of  rhizome  transplant  easily,  however. 

One  peculiar  water  plant  known  as  water  fern  or  floating  fern  (Ceratopterf.sJ 
is  an  attractive  addition  to  the  sh-^.llow,  c^.ady  end  of  pools.   It  is  not  hardy

,  iP2.n.t|Le£xn  c^.ata)  ,  ,,-oldon  club  (Or^K.jtrun  aouniciiri)  ,  an:,  several  species  of 
Sagittaria  and  water  shield  (Brasenia  :,:nin:urea^"!

as  larp  as  German  or  Japanese  iris,  but  they  are  beaut ifnllv  colored  fron  v;hibe 
throurh  various  shades  of  blae  to  darh-violet. 

Rock  ,,-;ar-lens  are  steadily  .-aininr:  in  -^o-cularity  in  Flori'^a  and  rr^.ny  of  our 
native  plants  are  well  adapted  to  this  fori,  of  horticulture.  For  the  .umn^  v-cd- 
rarden,  cacti  areusually  an  iuportant  ela.:ont.  The  various  native  s-oecies  of  '"

^;   l-r,,e  flowers  are  delicately  colored  and  the  brif.:b.t  fniits  that  follow  ar-  ' 
only  a  little  less  conspicuous.

How  can  we  in  Florida  have  flov.'ers  during  the  stimmer?  Tnat  is  a 
problem  that  gardeners  are  facing  ri.f;ht  now.  There  is  always  a  demand 
for  cut  flowers  for  the  home,  and  no  g3rden  is  complete  without  its 
bold  masses  of  colorful  flowers  blooming  liere  and  there.  The  annuals, 
those  that  must  be  planted  each  year,  are  an  important  group  for  these 
purposes. 


Ibny  garrlcners  i'l  Flori'!'":.  have  faid^^d  in  gro'virg  -"nnuals  ^vrirg 
summer,  and  yet  there  are  gardens  in  every  section  of  the  state 
each  summer  that  are  made  unusu-al' .^,  bnai.tiful  by  the  proper  uae  of  an~ 


the

The  main  obstacles  to  growing  -annual  floT/ering  plants  in  Florida 
during  the  summer  are  heat,  diseases  liki  the  wilts,  blights  and  mildews 
and  root-lcnot.  Axiy   method  of  spra^,  ing  for  the  diseases  or  of  treat- 
ing the  soil  to  get  rid  of  the  root-1-inot  is  usually  more  involved  than 
the  Beverage  home  gardener  v/ill  try,  and  yet  these  troubles  thrive  in 
the  s'oinmer. 


It  is,  thus,  up  to  ,:;ardenors  to  3.:;lect  plants  that  v/ill  grow 
and  flov/er  in  spite  of  ti  3,3e  troubles;  plant;  t!:iat  have  proven  to  be 
resistant  or  at  least  tcder^'nt  to  these  tro-n.">le3  and  to  the  heat  of

gardening,  and  from  this  li;jt  \,,^   can  pic^:  ■mniv.ls  for  aliaost  ariy  situa- 
tion or  location  in  the  ga,rden,  -annuals  of  a  v/ide  range  of  color,  and 
some  for  almost  -any  use.   In  -a  fo./  mo.ients  v.^.  -will  sugi^ast  I5  such  an- 
nuals with  a  short  discussion  about  each. 

You  should,  ho'i.'cver,  be  familiar  v.-ith  these  troubles  so  th-at  you 
will  knov/  them  when  they  appear  in  youi-  garden.  There  are  control 
measures,  and  many  gardonsrs  use  th^m  and  grow  flowers  that  would  not 
otlierwise  thrive.  Then  too,  on  infected  soils  you  should  plant  only 
the  ones  that  are  most  resistant. 

A  good  ex-omple  of  a  disease  prevalent  dxiring  the  siunmer  is  a  fun- 
gus loiown  as  Schlerotium  rolfsii  (SKle-ro'-shium  rolf-si')-   If  you  have 
^.riod  to  grow  hollyhocks  during  the  auifirnor  you  likjly  know  xt.  JJui-ing 
■warm,  moist  conditions  it  attacks  the  roots  and  base  of  the  stems 
at  or  just  below  the  grotuid  level  :ind  soon  causes  the  plants  to  rot 
off  at  the  ground.   It  attacks  a  nv>ber  of  plants,  and  is  capable  of 
remaining  in  the  organic  matter  of  the  soil  for  a  long  time  ready  to  at- 


-2- 

tack  any  stiscopti"ble  plant  that  is  plaut-.d.   Some  of  the  otlier  diseases 
likely  to  potuice  upon  siim  .c-r  anrinals  are  Aia-.iri"i:uTi  'wilt,  b-i.cterial  blight, 
and  thj  mildews  and  lt;af  3pots. 

Amons  the  insectr. ,  the  root-j-nict  nsr.-'',.tode:3  do  nr.ich  da^.iage  to 
summer  gai-'-ens.  These  nrnatodes  or  v.-oi-ms  thrive  h^ist  in  sandy  soils, 
an.d  they  live  over  the  \.-inter  in  old  roots  and  decaying  leaves.  When 
the  soil  vrarms  up  th'v  inc-/- aso  rapidly,  fe3dinsf^  on  the  roots  of  ten- 
der plants.   This  causes  the  characteristic  'rnlarging  or  knotting  of 
the  roots.   These  neriatodes  dra.v  sap  from  th.;  plants,  aii'.l  sometime  they 
become  so  abundant  that  the  susceptible  kindo  of  annuals  turn  a  sickly 
yellow  and  die. 

Aj'-d  nov/  for  that  list  of  sus'i'gested  aiUTJiil  flov/ering  plants  for 
youi'  garden  this  suiTiraer.   These  have  provon  successful  at  the  flov^or 
gardens  of  the  College  of  Agriculture  in  Gainesville,  and  in  numerous 
flower  gardens  over  the  state  and  are  I'Pcommended  over  a  large  area 
in  the  state.  They  should  b.3  planted  no.v,  ajid  many  \nse   gardeners 
will  malce  another  planting  in  about  ei.^ht  to  10  weeks  to  ins^ure  con- 
tinuous bloom  into  the  early  fall. 

As  native  asters  are  found  here,  it  is  reasonable  to  expect 
introduced  forms  to  do  well.  The  natives  art,'  small  flc  .v^red  perenuialsj 
v'hile  the  introduced  are  annuals,  v/hich  r-iises  some  doubt  as  to  their 
adaptability.  The  annual  asters  cor.dng  to  us  from  China  produce  larger, 
brighter  colored,  more  graceful  fl-.vers  than  native  varieties.  They 
are  rather  hard,  to  grow  in  our  soil  and  climate,  being  subject  to  serious 
soil  diseases  quite  difficult  to  control*  Yet  by  using  \/ilt  resistant 
strains  and  grov;ing  in  partial  siif'1-3  one  has  a  fair  chance  of  s\icceed- 
ing  with  them. 

The  old  favorite  toucla-me-not  or  balsam  is  easily  grown  and  at- 
tractive with  its  irregular  shaped,  bright  colored  flowers  of  pink, 
red,  purple  and  other  tones,  and  its  seed  pods  which  when  ripe  btijrst 
on  being  touched.   It  thrives  in  sun  or  partial  shade  and  deserves  a 
place  in  every  garden. 

Blanlcet  flower  or  G-aillar'''.ia  is  srrely  -.orth  a  trial.  The  yel- 
low, orange  and  dark  red  I'lcvers  are  oorue  on  long,  stiff  stems,  suit- 
able for  cutting.   It  seems  to  deliglit  in  s^i.dy  soil  and  sunlight.   It 
often  rese-  ds  it3';lf . 

Ajiother  flov/'er  for  the  sur.iraer  ■••arden  is  Calliopsis  or  brov/n-eyed 
Susan.  The  most  common  color  of  the  flowers  is  yellow  v.'ith  brovm  cen- 
ters, though  some  varieties  liave  maroon  or  red  centers.   It  is  shov^; 
free  flowering,  and.  blooms  all  sur.bior. 

Cockscomb,  which  grows  like  a  v;oed,  is  fine  in  that  it  adds  bril- 
liant color  to  the  garden.  Some  of  its  red  and  yellow  flowers  are  com- 
pact like  a  cock's  comb,  others  more  loose  and  plume  lik?.   It  is  at- 
t-^cked  by  root  knot  and  because  of  this  may  prove  disappointing  in  old 
infected  soils. 

Summer  Cosmos  is  an  annual  -..e  shoild  mention.  There  are  several 
colors  of  this  easily  grown,  pop-  lar  plc.rt,  such  as  white,  pink  and  var- 
ioxis  red  shades.  The  flow.-^rs  are  suited  for  cutti.v:^  There  is  an  au-

Annual  chrysanther.-rujns  of  scV'^ral  spocios  plante-."!  after  all  dan- 
ger cf  cold  is  past  will  by  simmer  produce  qu-ntities  of  sniall  yellc-w, 
white  or  mixed  colored  flowers  fine  for  cutting.  They  br-anch  and  spread 
so  as  to  cover  more  space  than  maiiy  annuals,  so  should  t-2  si'ven  a  dis- 
tance of  20  to  25  inches  apart. 

A  plant  which  may  be  sown  in  succession  from  late  winter  through 
spring  and  thus  be  >:ept  in  bloom  vigorously  well  into  sui-.Tmer  is  floss 
flower  or  a.'^erat-om.  Th  nost  common  color  is  blxie  cf  v/hich  there  are 
different  shades,  ther^  are  also  whites  and  pinks,  all  of  which  ma^r  be 
had  in  tall  and  dwarf  foriis. 

There  -arc  tlire-i  or  four  quite  differe::t  plants  knovm  as  bache- 
lor buttons,  one  of  the  most  desirabl.:  for  caltivation  is  f^lobe  amaranth, 
which  thrives  in  v/arm  weather.   It  produces  small  clover  like  haads  in 
■white,  red  cjid  oran;:;e.  They  are  rather  harsh  and  woody  and  may  be  cut 
and  dried  for  pernanont  boi-.quots. 

The  most  popular  for  dried  bouquets  is  strawflov/er  (Helicrysum) 
which  grows  tall,  producing  gayly  colored  flowers.  They  should  be  cut 
when  about  half  open,  the  stems  stripped  of  leaves  and  the  flowers  and 
hung  down  in  a  shaded  place  till  dry.  They  add  variety  to  the  garden 
before  cutting. 

The  marigolds  are  old  favorites  aaicl  have  been  greatly  improved 
in  recent  years.   Some  are  the  d  .uble  African  and  double  French  varie- 
ties in  various  colors,  often  v/if-i  combinations  of  color  in  one  flower. 
The  Orange  Prince  and  Lemon  Queen  African  varietiss  ar=  fine  aid  showy. 
They  bloom  in  late  summer  and  aut-omn.   Guinea  gold  is  a  r.ew  variety  of 
merit. 

The  petunia  is  prob_;bly  the  most  grovm  annual  in  Florida,  and 
may  be  seen  in  bloom  through  v/inter,  spring  and  su.imer.   In  addition  to 
the  common  single  bedding  varieties  in  many  colors,  there  are  the 
large  double,  giant  f  1-jffy-ruffles  and  ot:\  rs  vdiicn  are  striking  il- 
lustrations of  what  brer  din;;  ajid  sel^.ction  may  do  in  originating  nev/  and 
beautiful  forms. 

Portulaca  is  a  little  plant,  thriving  in  almost  any  soil,  provided 
it  gets  plenty  of  stu.light.   It  :.-aIces  a  fine  border  plant  in  siimmer; 
blooms  profusely  in  red,  pink,  orange,  white  and  other  colors.  There 
are  both  double  and  single  flowering  varieties.   Its  flowers  close  in 
the  afternoonc   It  is  of  gre-atest  valiio  a,s  a  low  edging  pl'.nt. 

Summer  gardeners  will  also  do  well  to  try  pincushion  plant.  The 
flovirers  are  borne  on  long,  slender  graceful  stems.   Colors  are  -v.hite, 
pinlc,  yellow,  blue,  red  and  other  shades.  Tlie  rounded  shape  ad.  pro- 
jecting staraens  suggest  small  pincushions.   They  last  well,  and  are  at- 
tractive as  cut  flowers,  as  v/ell  as  for  garden  decoration.  They  bloom 
thro-U{gh  spring  aiid  early  summer. 

It  seems  hardly  necessary  to  mention  the  sunflower  but  we  have 


such  attractive  chrysantJuraurn  flov;ci'ed,  double  f^lobc,  new  red,  dv/arf 
double  and  others,  that  are  desirabla.   Some  of  the  nov«-er,  small  flov.ered 
varieties  are  excellent  for  cvttin^ 

Verbena  is  a  v/ortliy  perennial  whicn  ma^''  be  treated  as  an  annual. 
It  is  a  trniling  r~raceful  plant  ;^ith  brijlit  foli-a~e,  and  lar^e  heads 
of  flowers  in  a  ."reat  variety  of  colors.   It  stands  snr.iner  sun  and 
rains  quite  well. 

Last,  but  not  lon.st,  the  zinnia  is  cne  of  the  most  sho'vTy,  easily 
/irovm,  and  satisfactory  annuals  for  sumiuer.   It  is  especially  popular 
in  the  ruj-al  districts.  IIo  flowi. r  has  been  i.iore  improved  by  breeding. 
We  now  have  j^iant  double,  Dalilia  lioworod,  cui'led,  c:-'ested,  picotee 
ponipon  and  others,  with  new  varieties  ap^jearing  in  cur  c:'.talo£jn.es  al- 
most every  year.   Zinnias  rive   a  fine  effect  v/hen  several  rcv/s  of  dif- 
ferent colors  cii'e  planted. 

No  atteiapt  has  been  made  to  include  all  that  may  be  {^rown.   One 
in  doubt  about  a  kind  v/hich  is  desirable  is  advised  to  ,;;et  a  small 
packet  of  seed  and  ti'y  it  cut.   If  one  succeeds  well,  let  us  laicw  a- 
bout  it  so  that  in  the  f'ltui'e  v/e  iva^/   tell  others. 

Seeds  of  the  sui^r^'-r  nnnv^.ls  usually  nominate  readily  in  warm 
weather.   It  is  best  tc.  protect  them  frcn  the  direct  rays  of  the  sun 
for  the  first  two  we.':s.   If  fc .  y  are  plr.:ited  in  flats  or  boxes  this  is 
easy  by  moving;  the  flats  to  th3  north  side  cf  the  house  or  by  shading 
them  with  cloth  or  slats,   Ca-eful  waterinj  ,f  the  plants  is  vital. 
The  summer  rainy  season  furnishes  liberal  amounts  of  water,  but  be- 
tween now  and  its  beginning;  is  a  critical  time  in  the  life  of  the  young 
annuals  and  often  rain  is  vei'y  scarco. 

Damping  off  is  one  disease  fhat  gives  gardeners  a  lot  of  trouble, 
and  it  is  one  they  can  control,  Pl-nts  with  this  trouble  simply  get 
weaJc  at  the  grcand  level  and  topple  over.   It  is  best  prevented  by 
using  one  cf  the  organic  mercury  compounds,  such  as  Semesaji,  according 
to  directions  on  the  soil  before  the  seed  are  planted  and  once  or  twice 
soon  after  they  are  up. 

Keeping  these  points  in  mind,  there's  no  reason  \;hy  every  gar- 
dener in  Florida  caruiot  have  masses  of  beautiful  annual  flowering  plants 
all  su-.Tiner.  Simply  plant  the  kin" -,  that  will  resist  heat,  diseases 
and  root  knot,  treat  the  soil  ajainst  da.':-iping  off,  and  give  the  plants 
regular  waterings  and  attention.  Of  couTse,  a  good  soil  and  fertiliza- 
tion is  necessary.

IHIS  FOR  FLORIDA  GARDEl-IS. 
H.  ?Iarold  Hume,  assistaiit  director,  research. 
Florida  Experiment  Station 


In  the  f:3rdens  of  most  parts  of  Aroericg,  iris  -olnnts  are  hia;h'iy  pri'^ed  ard 
freely  used.  There  are  groups  of  these  plants  adapted  to  wide  use  in  plantings 
along  stream?,  "beside  pools  ai:d  on  the  drier  soils  of  perennial  and  shrub  borders. 
Their  colorings  vie  with  those  of  the  rainbow  for  which  they  were  named.  Long 
years  of  exploration,  culture  and  hyCL-'dizi/f;  have  resulted  in  many  gorgeous 
forms.   Groups  based  upon  species  secured  in  foreign  lands  and  named  for  different 
countries  have  been  developed,  and  so  there  are  GeriiDn,  Japanese,  Dutch,  Spanish 
and  other  irises.   Iris  societies  interested  in  the  development  and  promotion  of 
this  favorite  flower  have  come  into  existence  and  have  done  m\ich  to  av/alcen  a 
gardening  interest  in  a  truly  wonderful  genu.s  of  plants.  But  u.nfortunately  the 
groups  as  commonly  known  and  developed  have  little  value  for  Florida  2;ardens. 
Their  planting  in  the  hope  of  securing  pen:'.ane.ut  dependable  sub^'ects  have  commonly 
ended  in  failure.   Sope  success  has  been  had  with  bulbous  forms  to  be  grown  for  a 
winter  season  and  then  discarded,  and  in  the  northern  sections  of  the  state  the 
old  Iris  florentina  (f lo-re^.-ti'-na)  has  found  a  place  —  introduced  long  ago  and 
passed  from  hand  to  hand  by  the  comradery  of  gardeners.  Here  and  there  a  few 
others  ha,ve  been  grown  but  usually  they  do  n  .>t  Iod  ;  ha-p-pj,   and  in  the  gardens  of 
Florida  the  iris  is  almost  unknow.i. 

However,  there  is  hope,  for  irises  of  several  s-oecies  are  native  Florida 
plants  foujid  here  and  there  where  conditions  suit  them  or  \?here  for  one  reason  or 
another  they  have  gained  a  foothold  all  the  way  fron  the  northern  boundary  to  Lhe 
area  known  as  the  Big  Cypress  southeast  of  Fort  I.Iyers,  Seven  species  are  listed 
f'.-.r  the  state  and  since  they  have  been  stu.died  with  fair  thoroughness  these  aro 
probably  all  that  are  native  within  our  bo'.mdaries.  This  list  of  seven  is  as 
f.-^llows:   Iris  savannarom  (sa-van-na'-rum)  ,  I.  hexaiF.'ona,  (hex-ag-o'-na)  ,  I_^ 
tvipetala,  (trip-et '-al-a)  !_•  Kinballiae,  (kim-bal-ee)  I.   Albisniritus 
"(a'-'-bi-spi-ri-tus)  I.  vir.Tinica  (vir-gin'-ic-a)  and  I.rivularis  (ri-vul-a'-ris)  . 

Before  describing  them  briefly  and  telling  yirhex'e  they  grow,  it  v.ill  be  bes':. 
to  say  something  about  the  structure  of  an  iris  flov/er.   Its  parts  are  arranged  in 
groups  of  threes.  At  its  base  is  a  three-celled  ovary  in  which  the  immature  seeds 
may  be  seen.  Later  this  develops  inti  a  seed  pod.  The  outer  parts  of  a  flower 
consist  of  three  setjals,  narrov/ed  below  into  the  "haft"  attached  to  the  top  of 
the  ovary,  widened  above,  drooping  or  curved  baci-^vard,,  Gardeners  call  these  the 
"falls."  Upright  and  between  the  falls  and  more  centrally  placed  are  three 
narrow  petals  called  the  "standards."   Usually  they  are  paddle- shaped.  Directly 


,2... 


overlapping  the  three  sepals  are  three  style  brejiches,  each  tipped  with  a  divided 
aroendage  that  is  commonly  fringed  or  toothed.  Beneath  the  three  style  branches 
are  -he  three  stamens,  each  consistr.ng  of  filament  and  anther.  On  each  sepal  or 
fall  there  is  usually  a  definite  marking  in  gold,  yellow  or  greenish  yellow, 
bearded  in  certain  species,  plain  in  others,  knora  as  the  "beard"  or  "crest". 
Veruaps  no  other  floiver  has  had  its  parts  divided  and  named  in  the  language  of 
.■^arciening  as  well  as  in  that  of  botany. 

All  cur  native  irises  are  raoisture-loving  plants  found  along  streams,  ponds  ar.^ 
lakes  in  different  parts  of  the  state.   Iris  savanuarum  is  the  most  ab^ondant  species 
o-:cuTTlng   in  great  fields' along  the  west  side  of  Lake  Okeechobee  and  westward  from 
the  ridge  between  Arcadia,  "^auchula  and  Avon  Park  toward  Brartenton,  Sarasota  and 
lOrt  Lfyers.   In  lesser  nurabers  it  is  found-  along  the  St.  Johns  river  as  far  as 
Jacksonville  and  on  the  west  to  the  Suwannee.   It  is  a  vigorous  species  with  sword- 
like leaves  30  inches  or  so  in  length  and  flo'"er--,tall:s  that  may  measure  as  much  as 
four  feet.  The  flowers,  (usually  four  or  five  are  produced  on  a  stalk)  are  large 
and  in  color  vary  from  pure  white  with  greenish  yellow  crest  throiigh  different 
shades  of  violet  to  deep,  almost  black,  violet.   Sometii'-.es  forms  with  standards  cf 
one  color  and  falls  of  another  are  found.   It  is  a  noble  species  of  great  value  as 
a  garden  plant. 

Closely  related  to  it  is  Iris  iqi-iballiae ,  a  smaller  plant  in  all  its  parts^with 
narrower  petals  and  upriglit,  ravjier-like  leaves.   It  is  kno-.n  only  from  one  limited 
area  in  the  vicinity  of  Apalachicola.   Several  other  plants  not  loiown  elsewhere  are 
to  be  found  along  the  same  river,  so  it  is  not  strajige  that  this  iris  should  be 
added  to  the  list  of  localized  species. 

Far  south  in  Florida  white  iris  are  often  seen  mixed  with  the  colored  ones 
growing  here  and  there.  From  aaong  the  white  fonns  Dr.  John  K.  Small  selected  one 
lorjTid  in  the  vicinity  of  La3elle  and  described  and  named'  it  Iris  Albispiritus.   It 
:  r.  a  lovely,  strong  growing  iris  with  pure  vhite  flowers,  the  sepals  of  which  are 
■:.arked  with  a  striking  golden  yellow  crest.  To  any  garden  it  would  be  a  noteworthy 
.  .'."'".itiono 

Iris  rivularis  is  l-novm  only  from  the  northeastern  section  of  Florida  where  ^ 
"Liltimreams  mal:e  their  way  no rt:  ward  into  the  St.  Harj-'s  P.ivur.   It  is  an  ir'^' 
of  medium  size,  blooming  quite  freely  even  when  small.  Later  than  Iris  saAra,rmaruir., 
j.t  is  of  value  in  prolonging  the  iris  season. 

For  a  long  time,  Iris  trifetala  wf.s  kno" 'n  in  Florida  oi.ly  west  of  the  Apala- 
chicola River  in  the  C-ulf  Coast  area.  More  recently  it  has  been  located  in  the 
northwestern  part  of  Duval  Cou-ity.  The  flowers  of  this  iris  are  different  from^ 
others  found  in  Florida  in  that  the  three  standards  are  so  greatly  ^educed  in  sir.e 
that  only  fragments  remain  and  these  ca :i  scarcely  be  secix.  The  effect  is  of  ^an 
iric  with  falls  only.  The  rhizomes  are  small,  about  the  size  of  a  lead  pencil  with 
swellings  or  enlargements  at  the  flowering  and  dividing  points.   It  is  easily  grown„ 
it  is  a  prize  among  irises  —  small  in  r.tature  (twelve  to  f  if teea  inches)  ,  dainty 
in  for."  In  color  three  forms  are  known:   a  pure  white,  a  good  violet,  and  a  very 
deep,  violet  purple.  Us-jally  it  is  not  in  flower  before  April  15- 

Iris  virginica  is  also  widely  distributed  in  the  state.   It  is  quite  common 
along  the  St.  Johns  T=iver  from  Falat'va  northward.   It  is  abundant  in  northeast ^ 
Florida  and  is  found  here  and  there  along  the  streams  of  western  Florida.   It  is 


-3- 


particularly  plentiful  along  the  lower  reaches  of  the  Escaffibia  River.   It  ia 
intsreov.ing  that  these  west  Florida  rer-:resen^.ptives  of  I.  vlrginica  are  light 
culored  (pale  violet)  and  sweet  sceiited.   In  the  northeastern  area  the  colors  are 
m-Qoh  darker  as  a  rule  and  sweet  scented  ones  are  rare.  This  species  may  be 
separated  readily  from  other  Florida  irises  because  it  has  rather  thick  fibrous 
rhiiiomes  that  are  pink  colored  v/ithin. 

Last  of  all  to  bloom  is  Xrii  ^^exagona .  Late  April  into  May  is  its  season, 
it  grows  readily  in  the  garden  and  blooms  even  when  quite  small.  As  a  rule  the 
flowers  are  a  good  dark  violet  with  thick  petals  and  wonderf^il  substance.   It  grows 
in  northeastern  Florida  and  again  in  the  angle  area  of  the  state  where  the  coast 
line  changes  direction  from  north  to  v/est  around  the  G-ulf . 

To  these  native  sorts  should  bg  added  as  suitable  subjects  for  Florida  gar.dens 
t?:at  wonderful  group  of  Louisiana  irises  discovered  by  Dr.  Small.   In  size,  in  color 
and  in  form  they  are  a  marvelous  collection  worthy  of  the  attention  of  any  gardener^ 
I  have  grown  three  of  these,  Iris  tgiganticaerulea,  (gi-gan-ti'-sir-u-lee--a)  Ir:  5__ 
fiilya^  and  Iris  Thomas ii  and  have  foujid  them  very  satisfactory.  These  three  ax'S 
blue  violet,  terra  cotta  arA   red-violet,  respectively.  There  are  many  others  in 
different  colors.   If  all  of  them  could  be  brought  together  in  one  place  and  all 
flowered  at  one  time  they  would  be  as  interesting  as  a  bed  of  mixed  pansies  and 
almost  as  varied  in  color,  Brownish-pui'ple ,  orange-red,  old- rose-lilac,  lavender- 
lo'.et,  darh  lilac,  crimsou-scarlet,  roya-l-p  u-ple ,  white  and  yellov/,  are  an;oi.^  ilic 
coi.-'rs  represented;  nothing  comparable  to  them  in  wild  plant  life  is  kno'/m  in  any 
otner  group  of  plants. 

The  crossing  of  these  southern  irises  among  themselves  and  with  other  groups 
ho.s  been  undertaken  by  several  iris  breeders.   Sorae  of  these  new  forms  are  now 
a-.allable  in  the  trade.  Others  are  sure  to  follow  and  doujtless  before  long  there 
'.'Till  be  developed  a,  V7ell-def ined  groixp  of  American  irises.   To  this  group,  Florida 
o-ardeners  should  look  for  their  iris  materialf:.   Catalogues  and  lists  should  be 
watched  for  the  nev;  ones  as  they  appes-r. 

Two  introduced  species  should  be  mentione'  ,  Iris  pseudacorus,  (pseu-ac'-or-ua) 
a  strong  growing  yello'-'  speci.s  native  in  Europe,  is  a  Iiandsome  robust  plant.   It 
forms  compact,  upright  clumps  and  the  leaves  are  readily  distinguished  from  these 
of  our  native  ones  by  the  p-^esc.-ce  of  a  well-defined  rib  dovrn  their  centers,   "t 
blooms  in  late  March  and  early  April  in  this  latitude.   Iris  unguicularis, 
(■uji-guic-ul-a'-ris)  or  stylosa,  fror;  l^orth  Africa  is  a  low-grov/ing  plant  that  bloor;.''. 
very  early.  The  flowers  are  hidden  among  the  leaves  and  they  are  delightfully 
fragrant.   It  may   be  had  in  pure  v/hite  and  in  br".,<;ht  lilac  marked  with  v,hite  and 
yellow. 

An  acid  soil  is  necessary  and  lime  should  be  kept  away  from  then.  A  study  c;f 
nvi'^y  native  iris  fioils  made  sometime  ago  showed  that  in  Florida  the  native  iri^iev; 
(■^rjw  in  soils  wiih  a  reaction  well  below  the  neutral  point.  Kence  soil  secured 
f^-om  places  where  thej;-  grov;  naturally  will  be  suitable  for  use  in  planting  the  Irr.?; 
garden.   Soils  v;ell  furnished  with  vegetable  matter  are  much  to  their  liking.  An 
a'''.-.j;dance  of  iiumus  helps  greatly  in  maintaining  uniform  moisture  condition, 
pr;''ides  food  as  it  decays  and  is  generally  helpful  in  growing  good  plants.   In 
preparing  the  soil,  dig  out  a  foot  and  fill  in  nine  inclies  of  this  space  with  soil 
yucih  as  that  in  which  they  grow  naturally  or  one  containing  'v'oodsmold  or  peat  and 
well-rotted  dairy  fertilizer.  This  '.vill  leave  a  depressed  bed  three  inuhea  b-^li-'w

the  adjoijiini?;  curfaces.   Set  the  rhizoaes  close  together  V7ith  the  growing  tips  at 
the  GurfacBo  l!h.e   best  time  to  secure  plants  is  wlisn  thi  y  are  in  flov/er.   They  are 
easier  to  find  and  selections  uay  be  made  to  better  advanta^ee  than  at  other  T:imes. 
Cut  bac":  the  foliage,  leaving  stubs  six  to  eif^ht  inches  only,  pad:  firmly  in  place, 
i^ater  thorouglily.  The  advantage  of  the  depressed  bed  is  that' it  will  hold  water. 
Ccmmercial  fertilizer,  one  consisting  of  five  percent  ammonia^  seven  percent 
phosphoric  acid  and  five  percent  potash,  for  insbance,  may  be  given  from  time  to  tins 
at  the  rate  of  a  quarter  poured  to  a  squs.re  yard  of  surface.  Let  them  grovr  thick  and 
close  together.   They  may  be  planted  to  mal'e  rood  bold  clumps  by  themselves  or  they 
may  be  set  in  the  edges  of  the  shrubbery  border.  They  will  gro'-v  in  partial  shade; 
it  appears  best,  however,  that  they  should  be  in  S'unshine  contimiously  for  at  lea^t 
half  of  the  day. 

As  already-  stated,  these  native  irises  are  moisture- loving  plants.  They  grow  in 
damp  soil  and  usually  for  weelcs  at  a  time  they  are  in  standing  water.  Perhaps  it  is 
for  this  reason  that  garden  ma]:ers  have  ne^:lected  them  and  refused  to  mal.e  use  of 
them  in  their  gardens.  That  they  grov:  in  wet  places  is  not  a  good  reason  for 
failing  to  tr:/  them.  Just  because  there  is  an  abruidance  of  water  about  them  moyt  of 
the  time  is  no  indication  that  they  need  so  louch.   Indeed  it  is  a  safe  assumptio:: 
that  soil  inhabiting  plants  .vrowing  in  driiiip  places  often  have  about  them  more  water 
than  they  can  possibly  use;  much  less  will  meet  their  requirements.   The  principal 
tl-.ing  in  growing  iris  under  garden  conditions  is  to  water  copiously  and  fertilize 
gCi^jiOusly.   ViTnen  watering  other  plants  in  the  garden,  give  thein  a  more  generau'^ 
su-;piy  and  be  certain  that  thejr  do  not  suffer  during  their  active  growing  season, 

Wien  an  especiaJlj'-  fine  variety  i'  foiond  it  maj''  be  increased  by  division,  or  by 
making  cuttings  of  the  rhizome.  The  rhizome,  you  will  remember,  is  the  running 
strm  of  an  iris  that  grows  on  or  just  under  the  surface  of  the  soil,  ^en  a  native 
ic-'2   blooms,  the  flower  stalJ:  and  the  growing  point  from  which  it  started  both  die. 
Ac  the  sides  of  the  base  of  the  flower  stall:  other  shoots  start  out.  There  may  be 
t  vu  or  more.  These  maj/  be  separated  or  broken  apart  and  planted  as  separate  plants. 
Cuttings  are  made  "oy   cutting  the  rhisoue  into  pieces  about  two  inches  long.   When 
planted  flat  in  the  peatj?-  mixture  suggested  for  setting  plants  in  the  garden,  nearly 
e/ary  one  of  these  pieces  v/ill  give  a  new  plant  that  should  flov-er  in  two  years. 
Irises  are  easily  grown  from  ceed  planted  in  a  peaty  soil  made  by  mixing  peat  and 
sand  in  equal  amounts  by  measure.   Growin,:;  plants  from  seed  is  not  likely  to  be  us3c 
to  any  great  extent  except  for   the  production  of  now  varieties. 

Native  irises  are  worthwhile  rd'.itlons  to  our  gardens,  beautiful  when  in 
flower  and  good  masses  of  green  when  not  in  bloom.  Tlie  blooming  season  far  south  ir. 
the  state  rill  extend  from  late  January.'  throw,'"r-  A'oril.   In  the  northern  section:; 
th(.'  season  will  last  about  as  long,  Rtarti:ag  and  ending  later,  however.   Try  them  r

INSECT  FRIENDS  OF  GARDEN  PLANTS 


W.  L.  Thompson,  assistant  entomologist 
Florida  Experiment  Station. 


^enever  man  attempts  to  grow  plants,  either  for  food  or 
ornamental  purposes,  one  of  his  main  problems  is  tl?e  control  of 
insects.   You  know  how  disheartening  it  is  to  grow  a  bed  of  fine 
flowers  or  some  fine  shrubs  and  then  have  insects  destroy  them. 

Many  times  insect  pests  will  gain  headway  before  they  are 
noticed,  but  in  the  same  unnoticed  way  there  are  myriads  of  others 
that  prey  on  these.   There  are  beetles  that  eat  scale  insects, 
there  are  other  insects  that  enjoy  a  nice  meal  of  aphids  or  plant 
iice,  there  are  robber  flies,  assassin  bugs,  mosquito  hawks,  there 
are  insects  that  aid  in  pollination  of  plants  and  hundreds  of  others 
that  are  friends  to  every  one  who  attempts  to  grow  plants. 

As  a  country  becomes  more  settled  and  civilized,  damage  by 
insects  increases  for  a  number  of  reasons.   First,  in  clearing  the 
land  the  natural  food  plants  have  been  removed  so  the  insects  take 
what  man  has  planted,  and,  second,  marjy  pests  have  been  acciden- 
tally imported  from  other  countries  into  ours  where  they  have  no 
natural  enemies  to  hold  them  in  check.   All  that  it  takes  to 
impress  upon  our  minds  the  importance  of  friendly  insects,  is  for 
some  foreign  pest  to  become  firmly  established  in  our  country  and 
then  to  watch  the  futile  efforts  of  man  against  it.   Invariably, 
he  goes  to  the  native  home  from  which  this  little  "bug"  came  in 
order  to  study  and  collect  its  natural  enemies  and  to  bring  some 
back  so  that  he  may  have  at  least  a  chance  to  hold  it  in  check. 

Many  insects  are  valuable  as  parasites  and  predators,  while 
others  play  an  important  part  in  their  ability  to  ca,rry  pollen 
from  one  flower  to  another,  thus  enabling  plants  to  bear' fruit. 
Some  insects  in  the  larva  stage  may  be  injurious  to  plants  but 
beneficial  in  the  adult  stage  as  carriers  of  pollen. 

In  almost  every  important  order  of  insects  some  of  them  are 
predacious;  that  is,  they  feed  on  others,  or  suck  the  fluids  from 
their  bodies.   Those  that  live  within  the  body  walls  or  inside  the 
eggs  of  insects  are  commonly  called  parasites. 

In  the  order  to  which  grasshoppers  and  roaches  belong,  we  have 
tne  praying  mantids  and  soothsayers.  These  long  slender  insects 
derive  the  name  "praying''  mantids  from  the  shape  of  their  front 
legs  which  are  enlarged  and  held  in  such  a  way  as  to  suggest  an 
attitude  of  prayer.   They  are  by  no  means  praying,  but  waiting 


2  - 


patiently  until  some  so ft -bodied  worm,  moth,  bee,  or  fly  comes 
their  way.   The  victim  is  caught  and  held  between  the  two  front 
legs  until  eaten.   The  mantids  do  not  restrict  their  diet  to 
injurious  insects,  as  they  devour  bees  and  other  beneficicl  forms. 

Dragon  flies  are  among  our  most  beneficial  insects  but  are 
seemingly  much  misunderstood-   Such  names  as  snake  doctors,  snake 
feeders,  and  mule  killers  are  used.  These  flies  are  also  often 
Called  mosquito  haV^s ,  ivhich  is  more  appropriate,  as  they  do  con- 
sume great  numbers  of  mosquitoes  as  well  as  mxany  other  insects. 
The  dragon  fly  adults  secure  their  food  while  flying,  but  the 
larvae  live  in  the  water  and  feed  on  many  kinds  of  aquatic  animals. 

One  family  that  especially  interests  gardeners  is  the  lacewing 
flies,  or  aphid  lions.   The  adults,  as  a  ru].e ,  are  rather  fragile, 
having  lace-like  wings  and  some  have  golden  colored  eyes.   The 
adults  are  very  attractive  but  it  is  the  larva.e  that  v/e  are  more 
interested  in.  since  they  are  feeders  on  ple.nt  lice,  mites  and 
scale  insects.   The  ;^-reen  lacewings  are  quite  common  m  Florida^ 
The  adults  deposit  their'wal  shaped  eggs  on  long,  hair-like  stalks 
that  are  attached  to  the  leaf  or  stem  near  the  host.   The  larva 
is  rather  flat,  the  body  tapering  boward  both  ends,  giving  it  the 
appearance  of  a  miniature  alligator >   It  has  sharp  grasping  jawa 
wii.-i.  which  to  catch  and  suck  the  body  jices  from  its  prey. 

The  trash  bug  lo.rva,  another  of  the  la,cewing  flies  is  an  in- 
teresting little  f->ilow  to  watch.   After  he  has  sucked  the  fluid 
from  the  body  of  his  victim, he  tosses  wiiat  is  left  of  the  un- 
fortunate insect  on  his  back  "'here  it  sticks.   By  the  time  the 
larva  is  mature,  it  looks  like  a  tiny  tra^a  pile  moving  over  the 
leaf. 

Doodle  bugs,  or  ant  lions,  another  interesting  family,  feed 
largely  on  ar.tSc   The  larva.e  are  rather  fierce  looking  felloiws, 
resembling  the  aphid  lions  in  general  appearance;  except  they 
are  larger  ai^d  have  broad  bodies,  with  ja^s  or  mandibles  that 
are  long  and  sharp.   They  make  a  funnel  shaped  pit  about  one  and 
one-half  inches  in  depth  in  loose  s-^nd  to  tr-io  the  ants.  The 
doodle  bug  stays  just  under  the  surfnce  of  the  sand  at  the  bottom 
of  the  pit,  and  i-;hr:.n  an  ant  falls  into  the  trap,  this  insect  at 
once  starts  thrc-'jng  sand  to  ur^^vent  thc^  ant  i  com   crawling  up  the 
side  of   the  pit  and  a.t  the  same  time  sticks  long  piercing  jaws  to 
the  surface  to  c>^tch  the  victim.   If  he  is  successful  in  catching 
his  prey,  he  pulls  it  down  out  of  sigl;t  and  devours  it.   Many  of 
these  small  pits  may  be  seen  in  the  garden,  under  trees,  shrubs, 
or  almost  any  place  ''che.ve  the  sand  is  dry  and  loose. 

Among  the  true  br<r;s ,  which  have  piercing  or  sucking  mouth  pa^ts 
are  many  beneficial  species  which  prey  on  other  bugs,  as  well  fi2 
beetles  and  soft-bodied  insects;  such  as  caterpillars  and  worms. 

The  assassin  bugs,  long  and  very  slender  individuals,  lie  and 
wait  for  their  prey.   Thfiy  feed  on  aphids,  le,a,fhoppers ,  and  other 
bugs,  worms,  butterflies,  and  bees.   The  usefulness  of  these  bugs 
is  somewhat  questioned  since  one  of  the  favorite  foods  is  bees. 
The  ambush  bug  is  another  predacious  insect.

_  3  - 

Although  many  true  flies  arc  great  pests,  there  are  quite  a  few 
families  that  are  bencficia.l.   One  of  tlie  moat  common  of  these  are 
syrphid  flies.  The  adults  of  some  species  resemble  honeybees  but 
we    ire  not  so  much  interosted  in  this  slr<i^e   as  i-'e  are  in  the  pre- 
dacious larvae,  which  consum-i;  .cany  a.phidp,  or  plant  lice,   The 
larvae,  maggot,  or  grub-like  individuals,  may  be  observed  in  the 
midst  of  an  aphid  colony-   A  hungry  larva  can  eat  an  aphid  in  less 
than  a  minute  and  often  consumes  over  two  hundred  in  one  day.   There 
are  several  species  common  in  Florida-   These  are  found  feeding  on 
aT3hids  infesting  turnips,  eggplants,  peppers,  rose  bushes,  and  many 
other  garden  and  shrub  plants  found  nround  the  home.  They  are  more 
common  in  the  fall,  ^-^inter,  and  early  soring  months.   During  the 
early  s"oring  months,  I  ho.ve  often  observed  a  small  colony  of  aphids 
st^.rting,  with  one  small  syrphid  fly  larvae  in  its  miidst;  a  week 
later  the  colony  of  «phids  ws  gone.   Had  this  colony  of  sphids 
escaped  the  '-■^tchful  eye  of  the  adult  syrphid  fly  that  deposited  an 
egg  in  their  midst,  it  nould  have  increased  many  times  during  the 
next  couple  of  months. 

The  Tachinid  flies  are  a  large  and  beneficial  family  but  they 
work  in  quite  a  different  manner  from  the  syrphid  flies.   Again  it 
is  the  larvae  in  which  ^^e  are  interested.   They  are  commonly  knoiim 
as  parasites,  because  they  live  inside  the  body  of  the  host  and 
are  not  visible,  consequently  the  good  they  do  is  often  overlooked. 
The  fly  deposits  her  egg  or  eggs  on  the  body  of  the  host.   After  the 
yoi-mg  maggot  hatches,  it  bores  into  the  body  of  the  insect  and  at 
first  feeds  on  the  body  fluids,  but  later  attacks  the  vital  organs, 
the  host  dying  about  the  tiuie  the  parasite  larva  has  matured.   In 
many  species  the  matured  larvae  cra.wl  out  of  the  host  and  pupate 
or  change  l  i-om  the  ma^^.^ot  to  the  adult  singe  in  the  ground  or  under 
some  trash. 

In  Florida  at  least  t'^o  species  of  this  fa'nily  live  on  the  green 
pumpkin  bugs.   The  adult  of  one  species  is  sometimes  called  the 
"feather  legged  fly"  because  of  the  fringe  on  its  hind  legs.   They 
feed  on  nect^^r  and  m.ay  often  be  seen  -"here  plants  are  blooming.  The 
adult  of  another  species  attacking  pumphin  bugs  resembles  the  house 
fly  but  is  somewhat  larger.   Many  ot  our  leaf  e-^ting  "^orms  and  cater- 
pillars are  parasitized  by  vrrious  species  of  this  insect.   They 
also  kill  grasshoppers,  cane  borers,  and  a  host  of  other  injur ioua 
insects . 

Another  fnmily  includes  the  robber  flies  '-'hich  are  considered 
both  injurious  and  bencficia.l  as  they  Dr.?y  on  bees  as  well  as  other 
insects.   Both  the  adult  and  larva  stnges  are  pred-'Cious.  The  adults 
are  rather  largo,  slender  flies,  catching  their  orey  on  the  i-ing  and 
feeding  on  them  by  inserting  their  bill  or  feeding  tube,  into  the 
body  and  extr-icting  the  body  fluias.  The  larvae  feed  in  decaying 
'■'ood  pjid  are  also  predacious  on  oth^r  insect  larvae. 

Among  the  beetles  are  the  ladyb -etlcs ,  orobably  the  best  known 
friendly  insects.   The  ladybeetles  belong  to  a  rather  large  family 
and  the  good  they  do  is  hard  to  estimate.   Their  value  to  the  fruit 
gro-"cr  and  gardener  is  so  great  tha.t  experts  are  often  sent  to 
foreign  lands  to  collect  and  introduce  nc"  species  into  this  country. 
In  Florida  the  different  soecies  range  in  siza  irom  the  head  of  a 


_4- 

small  pin  to  one-fourth  of  an  inch  in  diameter.   The  adults  are 
usually  hemispherical  in  shape,  the  color  varying  greatly  with 
different  species.   The  o.dults,  as  well  as  the  larvae,  are  preda- 
cious.  The  eggs,  are  cigar  shaped,  and  deposited  in  groups  . 
or  singly;  those  deposited  by  a.phid  feeders  are  usually  yello"'  in 
color.   The  larvae,  as  a  rule,  are  rather  hairy  fellows,  slender  in 
shape,  and,  as  mentioned  with  the  lace^'ing  larvae,  resemble,  some-  1 
vrhat ,  a  miniature  alligator. 

Some  years  ago  the  cottony-cushion  scale  was  infesting  citrus 
trees  to  a  great  extent  and  was  found  to  be  very  hard  to  control  by 
spraying.   The  Vedalia  ladybeetle  -as  introduced  from  California 
but  formerly  California  had  introduced  it  from  Australia.   By 
liberating  a  small  colony  of  a  dozen  or  more  of  these  beetles  in  a 
heavily  infested  grove,  the  cottony-cushion  scale  was  destroyed  in 
a  few  months.   This  one  species  of  ladybeetle  has  saved  the  fruit 
grower  many  millions  of  dollars.   The  cottony-cushion  scale  does  not 
limit  Itself  to  citrus  but  infests  other  trees  and  shrubs.  So  this 
little  beetle  is  not  only  of  great  value  to  the  fruit  grower  but 
to  any  one  who  has  shrubs  around  the  house. 

The  ground  beetles  are  predacious  on  cut  ^^^orms  and  a  number  of 
caterpillars..  They  are  found  under  logs,  or  boards  and  in  the  soil, 
and  come  out  mostly  at  night  to  feed.   They  vary  in  size  from  one- 
fourth  to  one  and  one-half  inches  in  length.   The  most  common  ones 
are  black  but  some  are  marked  ^dth  gold,  green,  and  purple  tints. 

The  blister  beetles  are  usually  considered  injurious,  but  some 
species  feed  on  the  eggs  ol  grasshoppers,  and  in  some  instances  do 
a  great  deal  of  good. 

There  are  many  species  of  very  small  -"asp-like  insect  parasites. 
Some  of  these  insects  are  so  small  they  are  almost  microscopic 
Instead  of  a  stinger,  as  in  the  true  wasps  and  bees,  they  have  a 
very  long  ovipositor,  or  egg  tube,  which  enables  them  to  deposit 
their  eggs  within  the  body  of  the  host.   In  a  few  days  the  egg 
hatches  and  the  yoi.mg  grub  starts  feeding  on  the  body  fluids  but 
usually  does  not  at  first  destroy  the  vital  organs  of  the  prey,  for 
it  grows,  01  ten  reaching  maturity  and  sometimes  pupating.   By  the 
time  the  host  has  rea.ched  m^-turity,  the  parasite  is  also  full  grown- 
Some  species  pupate  inside  the  body  ^all  of  the  dead  host  and  emer-e 
as  adults  while  others  crawl  out  and  attach  their  cocoons  to  the 
outside  of  the  dead  host.   It  is  quite   surprising  sometimes  to  find 
a  cocoon  and  take  it  in,  expecting  to  have  a  beautiful  moth  or 
butterfly  emerge,  but,  instead,  a  large  number  of  minute  wasp-like 
insects  come  out.  There  may  be  one  parasite  to  an  individual,  or 
there  may  be  many,  depending  on  the  species  of  parasite  and  also 
the  size  of  the  host. 

There  is  a  group  of  tiny  insects  that  pajasitize  aphids,  as  ^tpII 
as  certain  grubs,  web  -orms,  and  other  caterpillars.  On6  can  form

parasite  has  emerged. 

There  are  other  species  in  this  order  that  parasitize  the  eggs 
of  other  insects.   The  pumpkin  bug  eggs  are  often  parasitized  so 
that  instead  of  a  young  pumpkin  bug  hatching  out  a  minute  adult 
parasite  emerges. 

Although  the  bees  are  not  predacious,  they  are  real  friends  of 
garden  plants,  as  they  are  instrumental  in  pollenizing  many 
flowers  that  rould  not  bear  fruit  were  it  not  for  the  bees  carry- 
ing the  pollen  irom  one  flower  to  another.   Bumble  bees  were 
introduced  into  Australia  to  make  it  possible  for  clover  to 
mature  and  seed-   The  bees,  of  course,  are  not  responsible  for 
all  the  pollen  that  is  carried,  for  many  other  insects  feeding 
on  nectar  also  carry  it. 

Here  in  Florida  we  are  bothered  with  many  injurious  insects, 
but  we  are  blessed  with  many  that  are  beneficial,  too,  and  for 
almost  every  injurious  one  there  is  one  or  more  to  hold  it  in 
check. 

It  should  be  understood,  also,  that  although  we  have  many 
friendly  insects, ^'e  cannot  depend  upon  them  to  al^i^ays  control 
the  injurious  ones,  as  they  too  have  parasites  and  predacious 
enemies.   Nature  has  seen  to  it  that  one  family,  or  one  kingdom, 
cannot  entirely  eradicate  the  other,  but  merely  hold  each  other 
in  check  so  that  all  might  taste  the  fruits  of  the  earth.

HIBISCUS,  ITS 'PLACE  III  FLORIDA  GARDEiaiTG. 
W.I.;.  Pifield,  assistant  horticulturist 
Florida  ExDeriment  Station. 


The  late  Charles  Torrey  Siapson,  one  of  Florida's  most  beloved  naturalists, 
describes  the  cultivated  hibiscus  as  "easily  the  Queen  of  Flowers  in  South 
Florida".  Certainly  it  is  found,  growing  nearly  everywhere  in  the  lower  portion  of 
the  peninsula  and  in  many  places  as  far  North  as  Jacksonville.   Introduced  into 
Florida  from  Asia,  probably  China,  it  has  woven  itself  into  a  permanent  place  in 
our  landscape  design.   It  is  built  of  sterner  stuff  than  many  of  our  more  delicate, 
jjampered  ornamentals,  and  has  adapted  itself  to  a  wide  range  of  soils  and  cultural 
conditions. 

The  Malvaceae,  or  Mallow  fainily,  to  which  it  belongs,  is  divided  into  a  number 
ri  genera  familiar  to  most  of  us.  Tlie  genus  Goss^rpium  contains  the  cotton  plant 
r,nd  another,  the  genus  Malvaviscus,  includes  the  red  flowered  ornamental  called 
[Turks  Cap,  or  the  "^ax  Mallow.  A  third  member  of  the  faxiily  is  the  genus  Hibiscus, 
from  which  the  cultivated  hibiscus  gets  its  name. 

It  must  be  remembered  that  in  botanical  classification,  a  genus  is  further 
subdivided  into  one  or  more  species.  For  instance  in  the  genus  G-ossypium,  we  find 
sea-island  cotton,  and  upland  cotton.  Likewise  the  genus  Hibiscus  is  divided  into 
species,  of  which  there  are  about  200  distributed  throughout  the  world.   Several 
species  of  wild  hibiscus  are  found  growing  in  Florida,  ivhere  they  are  native. 
Others  are  used  for  food.  One  is  the  conirnon  okra,  or  gumbo.  And  another  is  the 
roselle.   Its  succulent  tissues  contain  much  mucilage,  acid,  and  coloring  ma.tter, 
all  cf  which  combines  to  nmke  an  excellent  jelly.  Another  species  is  the  well- 
laiown  Rose  of  Sharon,  or  Shrubby  Altr.ea,  hardy  as  far  'Jorth  as  Connecticut.  The 
only  one  of  the  groun  \diich  is  comraonly  called  oy   its  genus  name,  however,  is 
Hibiscus  rosa-sinensis,  the  common  cultivated  form  known  generally  as  the  Chinese 
Hibiscus,  Rose  of  China,  or  the  Shoe-black  Plant.   It  gets  the  latter  name  from 
The  fact  that  the  natives  of  the  Orient  sometimes  use  the  dye  obtained  from  its  red 
petals  for  darkening  their  hair  and  eyebrows,  and  also  for  blackening  shoes. 

Recent  years  have  changed  this  setup  somewhat,  however,  and  a  few  other 
species  of  Hibiscus  have  been  introduced  into  Floric'.a  for  ornamental  purposes,. 
Lacking  any  other  corainon  name  they  have  a,ll  been  included  in  the  term  hibiscus.   In 
fact  these  species  have  been  frequently  crossed  with  rosa-sinensis,  and  so  muci.  30 
that  the  resulting  progen-f  have  so  many  new  characters,  and  such  a  mixture  of 
ancestry,  that  it  has  so  far  been  too  difficult  to  classify  them  into  any 
systematic  key  that  will  aid  the  ga.rdener.

Eibiscus  schizopetalus  ( lichiz-op-et'-al-ns)  comes  to  us  from  East  Africa, 
and  is  a  verir   'beautif-al  contribution,  differing  from  rosa-sinensis  in  that  it  has 
slender,  drooping  branches,  and  long- stemmed,  pendulous  flowers  whose  reflexed 
petals  are  beautifully  fringed,  H.  tiliaceous  (til-i-a'~ce-ous)  comes  from  the 
Hawaiian  Islands,  although  it  no  doubt  occurs  scattered  throughout  the  Old  "^orld 
tropics.   Its  blossom  is  tubular  in  form,  and  yellow.  Exotic  varieties  of  E. 
mutabil^s  (mu-ta'-bil-is)  commonly  laio^i/n  to  us  as  the  Confederate  Rose,  have  been 
brought  in  from  the  South  Seas  and  added  to  our  collection  of  large,  beautiful 
blossoms.   It  has  pale  flc'rers  in  the  morning  that  become  pink  later  on  in  the  dajr. 

The  present  day  forms  of  Hibiscus,  then,  are  quite  varied.  Thile  there  is  an 
almost  unliimted  variation  observed  in  shades  of  color,  there  are  only  three 
primary  dolors  in  addition  to  white  which  are  concerned  in  the  color  pattern.  These 
are  red,  yellow  and  orange.  Petals  vary  from  linear  to  almost  round.   Some  have 
v/'ide  bases  and  others  very  narrow  ones.   In  width  the  variation  may  be  from  a  half 
to  three  inches,  and  in  length  from  one  to  five  inches. 

The  leaves  of  different  varieties  vary  even  more.  All  forms  from  long  and 
narrow  to  almost  round  are  fouiil,  som.e  with  entire  margins  and  some  with  deeply 
lobed  and  serrate  margins.   Some  are  hairy  and  rougii,  others  softly  pubescent  and 
others  smooth  and  shiny. 

In  size  of  plant,  varieties  range  from  low,  dwarf  shrubs  to  tall  trees  with 
whip-like  growth.   In  som.e  forms  most  of  the  foliage  is  grown  near  the  tips  of  the 
v;;od  while  the  rest  of  the  '-'ood  is  naked.   Others  are  densely  covered  with  foliage 
T,;.roughout .  While  the  hibiscus  is  strictly  an  evergreen  shrub,  some  varieties  have 
ioss  leaves  at  certain  seasons  than  others. 

No  artificial  key  has  been  prepared  for  identifying  the  varieties.  The  forms 
have  merely  been  grouped  for  convenience  according  to  the  color  of  the  flower  into 
pinlcs,  whites,  salmons,  yellov/s  and  reds,  and  a  few  trade  names  ha\'-e  been  assigned 
to  the  better  known  varieties  based  on  this  system  of  classification. 

■There  are  three  general  tjjpes  of  shape  ass-ariied  by  hibiscus  flowers.  The  coral 
hibiscus,  as  exemplified  by  the  schizopetalus  varieties,  the  ones  from  East  Africa, 
and  all  hybrids  from  this  parent  have  more  or  less  recurved  petals  witli  wavy, 
scalloped  edges.   In  the  vast  majority  of  varieties,  which  now  number  six  or  eight 
hvmdred,  the  flower,  when  fully  opened  is  salver-formed,  or  saucer- shaped.  The 
third  group,  containiri)?  many  of  the  newer  varieties,  has  flowers  that  remain 
funnel-shaped  until  they  wilt. 

Nearly  all  hibiscus  flowers  open  early  in  the  morning,  and  begin  to  wilt 
i'L  late  afternoon.   The  greet  majority  are  one-day  bloomers,  although  a  few 
v.^vieties  will  retain  their  blossoms  in  good  condition  several  davs.   It  has  been 
ob.-erved  that  in  cold  weather  blossoms  v;ill  usually  last  longer  than  during  the 
h'/L  sijmmer  days.  Tlie  blooming  season  for  most  varieties  is  nearly  year  round, 
although  blossoms  are  most  plentiful  during  the  rainy  season,  and  after  the  new 
growth,  on  which  the  blossoms  are  borne,  is  formed.

A  very  successful  method  of  securing  new  plants  is  termed  "mossing''  or  Chinese 
layering.   It  consists  of  cutting  a  ring  of  bark  from  the  lover  portion  of  a  branch 
and  carefully  wrapping  the  wound  with  sphagnum  moss,  held  in  place  with  a  bandage 
of  burlap.  Roots  v/ill  be  formed  in  the  moss  usually  within  six  or  eiglit  weeks  if 
the  operation  is  performed  in  the  Spring.   The  branch  can  then  be  cut  off  below 
where  the  roots  have  formed  and  set  as  s.   new  plant.  Of  course  the  moss  must  be  kept 
moist  during  the  period  of  root  formation.  Plants  thus  started  will  often  blossom 
within  a  feiT  days  if  buds  were  present  before  severing  from  the  parent  plant. 

Hardwood  cuttings  will  usually  root  in  about  six  weelis,  if  made  early  in  the 
Spring,  and  when  set  in  the  ga-rden  will  generally  cone  to  blooming  age  in  about 
nine  months.  For  this  pur^oose  the  cuttings  selected  should  be  about  a  half  inch 
in  diameter,  five  inches  long,  and  must  include  at  least  two  leaf  scars,  or  nodes. 
Pushing  the  cuttings  into  coarse  sand,  kept  well  watered,  is  the  usual  procedure. 

The  whip  graft  is  used  principally  for  growing  one  variety  on  another. 
Ordinary  paraffin  impregnated  into  bleached  muslin  has  given  as  good  results  for 
a  ^Trapping  medium  as  the  more  expensive  beeswax  combinations.  The  graft  should  be 
made  as  far  down  on  the  plant  as  practical  to  provide  some  top  shade  for  the  healing 
surfaces.  Budding,  like  grafting,  has  given  best  results  in  the  early  Spring, 
r.-'-d  is  done  bv  the  shield  method.  Both  buds  and  grafts  usually  com.e  into  flower 
in  the  fall  if  the  operation  is  performed  in  the  spring. 

The  most  troublesome  pests  of  Hibiscus  are  the  scale  insects.  They  are 
generally  controlled  by  spraying  with  an  oil  emulsion.  Two  applications,  apr)lied 
in   the  Snring  about  ten  days  apart  are  usually  sufficient.   Sometimes  aphids  or 
plant  lice  give  trouble.  They  can  usually  be  killed  by  two  or  three  a'o-ili  cat  ions 
of  a  nicotine  spray  or  dust  made  at  three  day  intervals.  Hibiscus  are  also  more  or 
less  subject  to  nematode  injury,  and  should  not  be  planted  on  ground  known  to 
dontain  this  root-lcnot  organism.   Some  varieties  are  more  susceptible  than  others. 
One  grower  has  obtained  good  results  by  grafting  the  more  susceptible  varieties  onto 
the  common  red,  which  seems  to  be  more  resistant  than  some  of  the  others. 

Hibiscus  deserves  consideration  in  the  Florida  garden,  because  of  its  readj'' 
adaptation  to  most  corditions  found  here,  and  because  it  fills  such  a  variety  of 
demands  for  a  flowering,  evergreen  shrub  of  a  tropical  nature.  Hew  and  more 
beautiful  varieties  are  constantly  being  originated,  and  the  possibilities  in  that 
direction  seem  -unlim.ited.   Crossing  with  some  of  our  native  wild  Hibiscus  offers  a 
cliance,  perhaps,  to  develop  varieties  more  hardy  and  adaptable  to  the  colder 
evictions  of  the  state  than  those  we  now  have.  Experimenting  with  rootstocks  of 
c'.^-.f ferent  varieties  may  open  up  another  field  of  adaptation.  The  G-arden  Clubs  of 
S'L.'jrida  could  do  much  toward  s-oreading  the  popularity  of  the  new  Hibiscus  varieties 
in  the  state  by  familiarizing  their  members  ivith  the  new  forms.

Florida  Ex-ceriment  Station. 


A  good  lawn  consists  01  a  nice,  even  sod  of  fine,  closely  mown  grass.   Such 
a  lawn  usually  surrounds  the  front  and  sides  of. the  house  and  where  possible 
should  completely  surround  the  house  and  exterx'.  to  all  ]^rts  of  the  grounds  not 
otherwise  used  "by  supporting  landscape  material.  A  good  lawn  can  be  grown  any 
where  in  Florida  and  can  be  kept  nice  and  green  the  year  round.   Such  a  lawn  adds 
dignity,  grace  and  chari.i  to  the  home  and  surroundings  and  has  actual  and  sue- 
ofcantial  money  value  in  ad'.Vut'-on  to  its  esthetic  worth. 

?efore  a  person  can  f sta  jTish  and  r.aintain  a  really  beautiful  lawn  the-^w 
rusit  come  the  desire,  the  ability  and  the  means  to  do  it,  along  with  the 

■  oerinination  to  keep  everlastin^^ly  at  it.   If  \o.i  do  not  have  these  prerequisites 
J   u  may  accidentally  establish  a  good  lawn  if  you  happen  to  have  a  favorable 
-jcation  but  the  chances  are  your  lawn  will  sooner  or  later  go  to  pieces  through 
lack  of  proper  care  which  is  absolutely  necestiary  under  any  and  all  conditions. 

Any  one  of  the  f ollo\7ing  grasses  can  be  used  for  lawn  purposes  in  Florida: 
Bermuda,  St.  Augustine,  Centipede  and  Carpet.   St.  A-agustine  grass  is  the  best  of 
the  lot  for  shady  places  and  it  will  stay  green  under  lov?  temperatures  better  than 
any  of  the  others.   St.  Augustine  grass  is  the  only  one  of  the  four  subject  to 
chinch  bug  attack.  ^H  o^  these  grasses  are  subject  to  attack  by  the  brown  patch 
fungus.  Centipede  grass  sometim.es  turns  yellow  due  to  lack  of  iron  in  the  soil 
and  an  application  of  iron  sulfate  in  solution  usually  satisfactorily  relieves 
thie  trouble.  There  are  satisfactory  m.ethods  of  control  of  chinch  bugs  and  brown 
patch,  details  of  which  can  be  had  by  writing  to  the  Experiment  Station  at 
Gainesville  for  the  bulletins  dealing  with  lawns,  lawn  insects  and  disease,   Ve^-'y 
detailed  information  on  the  grasses  available  for  lawns  in  Florida  can  be  had  by 
aending  to  Gainesville  for  Larm  Bulletin  209. 

All  of  the  four  above  mentioned  lai,vn  grasses  are  subject  to  frost  damage 
as  evidenced  by  browning  of  the  leaves  soon  after  frost.  No  harm.,  however,  is  doir 
to  the  stolons,  runners  or  root  system  a.nd  these  grasses  soon  green  up  again  with 
the  coming  of  warm  weather. 

Bermuda  grass  is  the  finest  textured  of  the  grasses  which  can  be  used  for 
lawn  purposes  in  this  state  and  due  to  this  fact  will  m.ake  w?iat  is  generally 
considered  the  most  beautifv.l  la.vm   if  given  proper  attention.   On  the  other  hand 
Bermuda  grass  lawns  usually  give  more  trouble  with  weed  growth  than  lawns  of  the 
other  grasses  due  to  the  fact  that  the  gvoxind.   cover  produced  by  this  grass  is 
not  as  dense  and  complete  as  that  produced  by  the  others.  The  more  dense  the 
sod  and  the  more  compact  and  complete  the  ground  cover  the  less  chance  weeds

have  of  entering  and  s-arvivinf .   There  ai-e  tv.'o  strains  of  Bermuda  grass  used  for 
lavvns,  one  is  the  comiiion  Bermuda  v/ith  both  siu'face  stolons  and  underground  stems 
or  root  stocks.  This  one  is  v.'ell  knov/n  to  most  folks.  The  other  Bermuda  is  a 
strain  without  underground  ruaiers  and  is  known  as  St.  Lucie  Bermuda.  Usually 
the  St.  Lucie  strain  of  Bermuda  grass  has  a  little  shorter,  broader  leaf  blade 
with  hot  quite  so  deep  a  green  color  as  tne  comrion  Bermuda  grass.  Both  of  these 
Bermudas  make  quite  satisfactory  larn;s.  Tlie  St.  Lucie  strain  of  Berraurla  is  best 
suited  to  the  r/armer  section  of  Soutliern  Florida  and  has  done  particularly  well 
on  the  muck  lands  of  the  Everglades,  The  common  Bermuda  is  of  course  adapted  to 
all  sections  of  the  state.  Remember  that  Bermuda  is  not  as  well  suited  for 
growing  in  shade  as  is  St.  Augustine  grass. 

CaiT^et  and  Centipede^  grass  are  similar  in  general  appearance  and  growth 
habit  but  quite  readily  distinguishti  when  seeding.  The  Centipede  grass  has  a 
single  spike  borne  on  a  stem  three  to  six  inches  long  while  the  Carpet  grass  has 
two  to  three  small  seed  spikes  on  a  fine  wiry  stem  eight  to  twelve  inches  long. 
Under  natural  conditions  Centipede  grass  vdll  thrive  better  on  dry  soils  than 
will  Carpet  grass.  Both  grasses  produce  a  vary  complete,  dense  mat  of  grass  and 
once  established  are  little  troubled  with  weeds.   The  leaves  of  both  grasses  arc 
quite  alike  and  are  about  tv.dce  as  wide  as  those  of  Bermuda  grass  but  not  as  wide 
or  as  long  as  those  of  St.  Aug-astine  grass,  plenty  of  seed  of  Carpet  grass  is 
available  in  the  market  but  no  seed  of  Centipede  grass  is  available;  however, 
most  nurseries  of  Flori'"a  now  handle  vegetative  planting  material  of  Centipede 
grass.  The  Experiment  Station  has  several  strains  of  Centipede  grass  under 
observation  but  none  seen:  superior  to  the  strain  now  commonly  available. 

St.  Augustine  grass  also  known  as  Charleston  grass  is  probably  more  commonly 
u--;e<l  for  lawns  than  any  of  the  other  grasses  meritioned.  Despite  its  susceptibility 
to.  chinch  bug  attack,  which  usually  occurs  during  hot  dyry   spells  following  rauny 
periods,  St.  Augustine  grass  has  remained  very  popular  because  of  its  wide  range 
of.   adaptability  to  varying  soil  and  climatic  conditions  and  because  of  its 
Nihility  to  stand  more  cold,  more  shade  and  iiore  abuse  than  any  of  the  others  -and 
■■■''rill  remain  fairly  presentable.  There  ai-e  tv/o  strains  of  St.  Aiig-istine  grass 
.-i^'owlng  in  the  state.   The  common  St.  A'Jg'astine  grass,  well  loiown  to  miost  people, 
is  of  course  by  far  the  most  widely  used.  The  other  strain  has  a  variegat&d. 
color  leaf  be ixig  striped  green  and  white.  This  strain  is  little  used  and  is  not 
near  so  hardy  and  vigorous  as  the  comir.on  St.  Augustine  grass.   St.  Augxistine 
grass  doeenot  produce  any  quaiatity  of  viable  seed,  hence  vegetative  material  .is 
used  exclusively  for  propagatirg;  purposes.  Planting  Material  is  available  fro'i

Since -all  of  the  permanent  lavim  grasses  of  Florida  are  browned  by  cold  in 
jh-e-'fall  or  winter  except  \vhen  growiiig  in  the  southern  part  of  the  state  the 
•  •-oniaan.  practice  is  to  plant  seed  of  some  quick  growing;:,  short  lived,  winter  ha.niy 
g"ass  right  on  top.  of  the  permanent  lriwn  grass  in  October  or  early  November  to 
"Tnake  -  sure  0  f  a  nice  green,  lawn  all  duri  rg  the  fall  and  winter  months.  The  best 
.grass, for -this  purpose  is  Italian  rye  grass,  seeded  at  the  rate  of  about  six 
pounds  of  seed  per  one  thousand  sq-'oare  feet  of  lawn.   Italian  rye  grass  does  jio 
harm  to  .the  permanent  lawn  grass  provided  the  rye  grass  is  kept  closely  mowed 
especially  in  the  spring  when  the  Italian  rye  grass  tends  to  stool  considerably 
and  to  make.  rathe:r  heavy,  tall  growth  which  if  not  kept  clipped  off  often,  wilx 
tend  to-  smother  out  certain  of  our  lawn  grasses,  especially  Bermuda.,-

Hqv.  ao  to  the  preparation  for  •  lann   and  the  actual  estalDlishinf  of  lawns; 
first,  thought  should  be  given  to  enriching  the  area  "by  the  addition  of  plenty 
of  'rell  rotted  manure,  leaf  mold,  rich  soil  and  commercial  fertilizer.   Second, 
if  you  are  able,  put  in  some  kind  of  -later  systerri,  since  the  measure  of  success 
you  have  in  raaintaininf:  the  lawn  is  largely  determined  by  the  nearness  v/ith  '.vhich 
you  come  to  keeping  the  grsss  adequately  supplied  with  v/atjr  at  all  times  and 
the  more  convenient  and  efficient  your  system  for  watering  the  lawn  the  easier 
it  is  going  to  be  to  get  the  Job  done  quickly  and  efficiently. 

After  you  have  enriched  your  soil  and  put  in  the  water  systei.:,  care  should 
be  taken  to  level  tlie  gro  ind  before  actual  planting  of  the  grass  is  started. 
The  best  practice  is  to  ,;ive  the  ground  a  gradual  slope  away  from  the  building 
in  all  directions.   If  terraces  are  desired,  mai:"  them  grad^ially  sloping  and 
avoid  abrupt  edges  upon  v/hich  it  is  always  difficult  to  establish  goud  sod  and 
difficult  to  mow  in  such  a  manner  as  to  a,vo'"d  injury  to  the  grass.  2Ieedless 
to  say  all  building  material  waste,  such  as  atlcLc,  stones,  plaster  and  the  like 
should  be  removed  in  the  preparation  of  the  soil  preceding  the  planting  of  crass. 

Now  you  are  ready  to  plant  the  prfss.  Centipede  and  St.  Augustine  grass 
both  have  to  be  established  b^/  planting  ve;"etative  material,  that  is  rooted 
runners  or  sods  since  no  seed  is  availa^ble.   Carpet  and  Bermuda  grass  can  either 
be  established  by  planting  seed  or  the  use  of  vegetative  m.ateriai.   Bermuda  is 
usually  more  readily  established  by  planting  vegetative  material,  while  Carpet 
grass  is  more  readily  established  by  sowir^  seed. 

If  you  decide  on  using  ono'of  the  g-.-^'^sss  -hich  has  to  be  planted  vegetative", 
jet  plenty  of  planting  material,  wet  the  lawn  soil  down  thoroughly,  open  up  shallo 
furrows  about  four  inches  deep,  f o  ir  inches  wide,  and  twelve  inches  apart,  place 
the  rooted  runner  or  pieces  of  sod  in  these  furrows  and  almost  but  not  entirely 
cover  the  plantirg  material  bj-  pulling  the  dirt  removed  by  the  opening  of  the 
furrows  back  into  place.  After  planting  the  grass,  smooth  the  ground  as  best  you 
Lan  and  again  V7ater  the  lawn  thorou^iiy  and  after  this  'vater  often  enough  to 
keep  the  soil  reasonably  well  supplied  with  raointure. 

If  you  decide  to  use  a  gras?,  seed  such  as  Ben.uda  or  Carpet  grass,  be  sure 
to  get  pure  seed  of  high  genninatiiig  ability  and  f  ig^^re  on  at  least  foun  pound^- 
of  seed  per  one  thousand  sq-jare  feet  of  la-n  area.  Plant  one  half  of  the  seed 
broadcast  in  one  direction  a.ji  the  balance  broadcast  in  the  opposite  direction 
to  insure  even  distrxbution.  After  scedii:g,  rake  the  seed  in  and  water  the  lawn 
thoroughly,  being  carefi"'^.  not  to  v.'aGU  the  soil  and  cause  uneven  distribution  of 
the  seed.  Keep  the  grou:d.  moist  rt  alll  tin^js.  ITnile  the  grass  is  coming  up  a^r'. 
jetting  established,  take  o  it  objectionable  we^  do  by  pulMng,hxieing  or  mowing. 

Begin  regular  mowing  as  soon  as  the  grass  starts  putting  out  runners,  as 
this  induces  vegetative  growth  '"hich  in  turn  causes  a  more  rapid  sod  formation. 
Objectionable  weeds  that  cannot  be  controlled  by  the  ordinary  mowii^  of  the 
lawn  will  have  to  be  pulled  out  by  ha. J  ,  however,  mowing  and  the  tViickening  up 
of  the  sod  as  grov/th  prooresaos  xiill   autoratically  control  .  .ost  weed  grov/th. 

Once  you  have  your  lawn  thoroughly  established,  if  you  v/ill  control 
insects,  diseases  and  rodent  pest  your  principal  problem  is  to  keep  the  lawn 
grass  adequately  fed  and  properly  moved.  Tliis  meians  you  are  going  to  have  '-o 
fertilize  the  lawn  two  to  three  times  a  year,  once  with  a  complete  ieitili"^er 


)i

such  as  a  5-5-5  or  5-7-5  and  twice  or  nore  often  if  necessary  with  nitrogen 
alone,  using  such  materials  as  suli's.te  of  amnonia,  nitrate  of  soda,  calcium 
nitiato  or  cotton  seed  iT.eal.   Tbf  ra  is  not":iiig  i.'.o.^ic  or  i;.ysterious  about  the 
fertilization  of  lawn  grasses.   Oomrrionly,  grasses  respond  more  to  nitrogen  than 
to  phosphorus  and  potassium,  thougli  all  three  elements  are  needed,  hence  the 
reason  v/e  say  fertilize  once  a  year  with  a  fertilizer  containing  all  three  plant 
food  materials;  namely,  nitrogen,  phosphorus  and  potassium,  and  two  or  more  times 
a  year  with  some  fertilizer  material  carrying  mainly  nitroiren.   The  complete 
fertilizer  can  probably  most  advantageously  be  applied  in  the  fall,  winter  or 
early  spring  and  the  nitrogen  alone  fertilizer  suff icientlj'-  often  during  the 
growii^  season  to  keep  the  grass  a  vigorous  deep  green  color.   Remember  cotton 
seed  meal  is  good  but  slov;  acting:,  v/hile  nitrate  of  soda,  sulfate  of  ammonia 
and  calci^Jia  nitrate  are  readily  soluble,  quickly  available  and  will  leach  out 
of  open  sandj'  soils  duriiig  periods  of  heavy  rainfall.  P.emember  that  none  of  the 
fertilizers  can  give  their  plant  food  materials  to  the  lawn  grass  except  as 
these  materials  go  into  solution  whicli  simolj  means  the  soil  has  got  to  be  kept 
reasonablj'-  moist  at  all  timer.. 

If  you  '.fill  remember  arA   act  on  thesu  two  things,  nine  tenths  of  your  lavn 
troubles  will  be  over:   G-rass  does  bent  on  a  rich  moist  soil  arid  sod  forming 
'.rasses  of  Florida  thrive  best  -jjider  rather  frequent  n.owing,  all  of  which  simply 
neans  keep  the  lawn  well  fertilised,  v.-ell  watered  and  mov/  often  enough  to  keep 
".he  grass  a  desirable  height. 

Summing  up  then,  we  may  say  lawns  are  desirable  because  they  are  useful, 
-eautiful  and  profitahle.  G-ood  la-vi.s  can  be  had  in  Florida  the  year  round  if 
ihere  is  the  ddsire,  the  ability,  the  means  and  the  determination  to  have  the 
lawn. 

The  grasses  available  for  permanent  lawn  purposes  are  Carpet,  Bermuda, 
'"•entipede,  and  St.  Augustine.   The  best  r'trass  for  greening  up  lawns  in  winter  i^ 
..talian  rye  grass.  A  rich  moist  soil  naturally  or  made  so  and  care  and  attentio..- 
'.,0  fertilizing,  watering,  irxjwi  rg  a.id  the  control  of  rodents,  insects  and  disease 
will  give  desired  results  which  is  a  beautiful  year  round,  lawn.

iloi'ida  j5,griculttirf.l  >.'oeri;aent  St-ition 


At  the  outset  I  may  S3y  that  the  tei-m  "hulo"  is  used  here  in  its  broad 
flense  as  explained  and  defined  'i^y   Professor  '■•  Harold  IJuije  in  an  earlier  talk  of 
■:his  series.  Used  in  its  technical  arx'.  restricted  seuse,  the  word  bulb  refers 
to  a  special  plant  part  usiially  developed  uider  gro\ind  consisting  of  a  short 
s'i'em,  roots,  thickened  lea.f  bases  and  one  or  n.ore  ouds.   Its  stjecial  purpose  is 
to  act  as  a  storage  place  for  food  and  in  Kost  instances  it  serves  to  carry  fie 
plant  over  periods  unfavorable  to  active  gro'.vth.  The  trn.e  bulbs  are  either 
coated  with  tight  overlapping  thickened  leaf  bases,  as  in  the  onion  or  amaryll;.?. , 
or  scaly  with  loose  scale-like  leaf  bases,  as  in  the  bulbs  of  the  true  liliers. 
ii.  every  day  usage,  ho;vever,  the  word  bc.lb  commonly  includes  many  other  plari 

.■^:.-  f:/-*-   are   net  true  bulbs  b^.t  sei'^e  the  same  pT'.n;^ose,  and  in  garden  v/orir  -t-hev 
a..  3   handled  in  much  the  same  way.   The  corms  of  gladiolus  and  watsonia,  the  tubers 
J-  calladiiims  and  callas,  the  swollen  roots  of  dahlias  and  the  rhizomes  of  ginger 
-.'.d  iris  are  often,  and  indeed  usually,  included  a:aong  bulbs.   It  is  in  this  wider 
,r-!neralized  sense  that  the  term  is  u.  ed  in  this  discussion. 

The  harvesting  and  storing  of  tlie  various  kinds  of  b  ilbs  is  a  problem  of 
■Lach  diversity  and  complexity,  due  to  the  large  nwnber  of  different  kinds  of 
plants  in  this  group;  and  also  to  the  fact  Lhat  corm-iercial  practices  often  differ 
radically  from  those  best  suited  to  the  "Cr:ia.r;)ental  Gardener''. 

In  regard  to  their  rc-quirements  for  har's.  .;Sting,  >-albs  may  be  divided  into 
three  main  groups:   (1)   Tr.ose  in  which  the  tops  die  down  each  year  at  the  end 
of  the  growing  seasoa.  —  these  are  best  dug  (lifted)  annually;  (2)   Those  v/hich 
behave  better  if  taken  iip  jvery  t'Vo,  three,  evon  up  to  five  years;  (3)   Those 
which  are  allovved  to  rema  .n  indefinitely  in  the'  f round. 

When  we  mention  bjlbs  many  thiiilc  of  the  F-^rcissus  group.   This  member  of 
■^.he  flowering  bulb  group  is  one  of  the  oldest  of  cultivated  flowers  and  enjoys  a 
much  deserved  popularity.  Due  to  the  climatic  and  soil  conditions,  many  of  the 
iost  succes;:;ful  and  popular  varieties  in  otiier  parts  of  the  country  are  rather 
uniiatisf actory  when  grown  under  Florida  conditions. 

The  greater  part  of  the  narcissi  grov/n  in  Florida  consist  almost  entirely 
of  varieties  belonging  to  the  Polyanthus  or  Tazetta  group.  These  are  highly 
thought  of  in  Florida  because  they  bloom  during  the  winter  months.  The  most 
important  varieties  in  this  group  are:  Paperwhite,  Chinese  sacred-lily,  Grand 
Soliel  d'Or,  "Jhite  Pearl,  and  Grand  Konarque.  The  comr;-.ercial  growers  dig  each 
year,  which  is  necessary  in  order  that  the  stock  may  be  properly  sized  and  spa;od 
to  proauce  market  qualities.   For  the  oriiai-ental  gardenei  ,  i.j.,cvfc.,  Lhj  c  1^   n^ . 


::.!  !Cj  z   ... .  .^  .c;^:/  ard  v.:'"'.!  Ijb  :'.ctcr:r.incl  to  «or;ic  e:..tcr.t  ty  the  .rarj   in  wLi-li  tlie 
■^ulbs  are  iDeing  used.   In  general  though,  it  is  true  that  "best  resiilts  are 
obtained,  with  the  Polyanthus  t^/pe  o'   n.-r-rcissi  when  they  are  lifted  amma'^^ly; 
Fiien  left  to  naturalize  they  are  allo,v7ed  to  remain  undistarhed  indefinitely. 
The  trumpet  narcissi  and  the  jonquils  (rarcissus  odoris)  give  hest  resv.lts  if 
taken  up  every  two,  three,  or  even  up  to  five  years. 

It  has  heen  fo'und  that  Grand  Monax'que  is  very  satisfactory  if  left  to  grow 
on  for  a  niuaher  of  years  hut  the  statement  here  is  otherwise  all  right.   The  hulba 
can  oe  dug  from  the  time  they  he^^in  to  turn  yellov/  until  the  tops  ha.ve  completely 
died  down.  However,  they  should  he  dug  before  the  tops  have  disappeared  so  tha'-; 
the  clumps  can  be  located  without  difficulty.  They  should  be  lifted  before  the 
sumi:aer  rains  start  tl'.e  bulhi  into  second  growth,  or  their  vitality  is  likely  to 
be  seriously  impaired.   The  bulbs  shot\ld  be  picked  up  immediately  after  digging 
and  placed  in  the  shade,  "s  exposarc  to  the  sun  for  as  much  as  an  hour  will  often 
produce  sunburn,  which  is  followed  b?/  a  dry  rot  in  storage. 

Narcissus  bulbs  are  usually  kept  out  of  the  ground  for  three  or  four  months 
§fter  they  are  dug.  Therefore,  consi4erab:le  care  should  be  exercised  in  their 
storage.  The  bulbs  should  be  stored  in  a  place  that  is  dry,  cool  and  well 
ventilated.  This  is  best  obtained  in  an  open  shed  especially  made  for  the 
purpose,  which  has  shelves  that  v/ill  hold  a  number  of  shallow  trays  or  bins  m 
which  the  bulbs  are  placed.   If  it  is  not  possible  to  have  such  a  building  some 
place  that  meets  as  nearly  as  possible  the  conditions  given  above  should  be  used. 
Jnis  nay  be  an  attic  or  a  room  in  a  house,  a  cellar,  or  the  seed  room  in  a  barn. 
Jit  this  point,  I  mi/jht  mention  that  rats  and  mice  are  very  destructive  to 
narcissi  stored  in  this  manner,  injuring  and  cariying  away  many,  so  care  shoiiid  ce 
t.  ,ken  to  put  them  in  a  place  that  will  protect  the  bulbs  from  the  ravages  of 
these  rodents.  Durii>^  the  first  two  or  three  week.s  of  storage  the  bulbs  should  be 
sxamined  daily  to  determine  if  heating  is  taking  place  and,  if  so,  they  should  be 
i:tirred  in  some  way  to  alleviate  this  condition. 

After  the  bulbs  have  been  in  storage  for  six  or  eight  weeks  they  should  be 
cleaned;  this  consists  in  taking  off  the  oater  loose  husk  and  roots,  and 
C''.iparating  the  slabs  from  the  mother  bulbs.   The  balbs  are  then  put  back  into 
their  containers  and  kept  until  planting  time. 

Another  fine  group  of  bulbs  is  the  gladioli.  Tliis  flower  is  becoming 
increasingly  popular  each  year.  Their  popularity  is  deserved  because  of  theJr 
beauty  and  also  beca/^se  the  proper  choice  of  varieties  makes  it  possible  to  have 
them  practically  every  month  r'uring  the  year. 

The  commercial  grower  of  gl'^dioli  in  Florida  digs  his  bulbs  at  the  end  of 
ev-ery  growing  season,  Jul',  as  soon  as  the  average  tops  are  yellowing  and  ready  tc 
(lie  dovm.  Probably  the  best  practice  for  the  ornpmental  gardener  is  to  handle 
them  in  the  same  m^anner.   In  most  ca,ses  the  home  gardener  ivill  h^ve  only  a  small 
numiber  of  bulbs  as  compared  to  the  commercial  grower,  and  it  wo'old  be  v/ell  to 
leave  them,  in  the  gro'ond  until  all  have  matured.  At  this  point  I  v/ould  like  to 
state  that  there  may  not  be  any  necessity  to  dig  the  bulbs  every  year.  There  are 
numerous  cases  that  might  be  cited  in  which  the  bulbs  are  left  in  the  ground  for 
three  or  four  years  and  still  produce  an  excellent  bloom.   Tliis  practice  would  I3 
much  more  satisfactory  on  the  better  tr.pes  of  soil. 


Aftei-  digging,  the  Lulbs  and  surrounding  soil  s^^oald  preferably  be  screened 
so  tha.t  or.e  xvill  be  sare  -^.o  r^et   ail  ot!   the  cor.  .els  out  of  the  soil.  After 
screening,  the  bulbs  are  tai-en  to  the  curint'^-  shed  or  sous  convenient  place  and 
spread  out  in  shallow  trays  or  bins  to  dry,  after  which  they  should  be  separated 
and  cleaned.  At  this  time  ;he  old  bulbs  a_-e  detached  from  the  new  ones  and 
discarded.   In  cleaning,  t"je  o..vter  husk  should  be  taken  off  but  enough  husk  iviust 
be  left  so  that  the  bulbs  will  not  dry  out  to  an  excess. 

The  bulbs  should  then  be  put  in  the  trays  or  bins  and  stored  under  conditioris 
comparable  to  those  needed  by  narcissi.  During  storage  certain  definite  chan.';es 
take  place  in  the  bulbs  —  this  is  knovm  as  curing.  The  length  of  time  for  this 
varies,  but  is  usually  from  six  weeks  to  four  months .  The  best  way  to  tell  when 
this  process  has  been  completed  is  to  watch  the  buds  for  signs  of  growth,  and  when 
the  buds  show  evidence  of  growth  the  bulbs  should  either  be  planted  or  placed  in 
cool  storage  so  as  to  prevent  further  development.  The  same  precautions  in  rcgarc^ 
to  preventing  the  ravages  of  rats  and  nice  slrould  be  practiced  as  recommended  for 
narcissi. 

Many  home  gardeners  have  Easter  Lilies.  The  Easter  Lily  nay  be  left  in  i.hj 
l^'- --rnd  all  sumner,  but,  if  du{^,  this  shovld  be  d.o-^e  just  before  rooting  stpr-^*- 
which  is  usually  late  in  August  or  September.  The  principal  reason  for  digging 
i.~  ;.c  prevent  root  binding  in  clumps;  tiiercfore,  it  is  only  necessary  to  lif.: 
them  every  two  or  three  years  when  t>;;y  may  be  divided  and  replanted.  They  may 
b.5  rebedded  immediately,  or  put  in  sens  cool  dry  place  away  from  air  c\irrents 
wh'','2h  will  dry  them  out,  causing  them  to  wilt  and  shrivel  and  lose  their  vitalii.y. 

Turning  to  the  A.naryllis ,  as  has  been  poirited  out  by  Professor  Hume  in  an 
f&rlier  talk  in  this  series,  the  plants  that  are  comn-only  called  Amaryllis  are 
;'.ot  Amaryllis  at  all  but  really  Eippeastrums.  Tho  ones  most  commonly  found  in 
i'lorida  are  the  small  ones  with  bright  red  flo:  ers  and  the  large  flowered  hybrid 
i^jnaryllis. 

These  bulbs  may  oe  left  in  their  permanen'-  location  from  year  to  year,  the 
only  reason  for  lifting  tb,  .1  beii--,^  the  wish  to  "!han,»e  them  to  another  desired 
location,  or  to  give  them  ew  soil  that  better  grov/th  may  be  secured. 

Mayte  you  are  wondering  when  to  dig  day  li''ies.   The  clumps  can  often  be 
left  undivided  for  four  or  five  yea.rs  without  lo3S  in  siae  or  number  of  flowers „ 
The  only  object  of  digging  and  replantizag  is  to  divide  them,  thin  them  out,  and 
fu..'nish  the  bulbs  with  plant  food,  and  a  better  soil.   They  should  be  replanted 
inimediately  after  being  dug,. 

Another  group  that  may  be  left  indefinitely  in  their  permanent  location  is 
-  •---nums.  This  group  consists  of  several  species  which  are  commonly  fo'ond  in 
i'iorida,  all  of  which  are  evergreen, 

Montbretias  or  Blazing  Star  may  be  dug  Yihen  foliage  dies  down  in  the  fallj 
and  stored  the  same  as  gladioli;  or  they  may  be  left  in  the  ground  for  two  or 
thi-ee  years  until  the  clumps  become  root-bound,  when  they  should  be  lifted  and 
u..^-.idede   Snowf lake 3  are  best  allov/ed  to  rc.uain  -onaisturbed  for  a  nui:.ber  of  i^.,— ... 
Evcesias  sometimes  at  the  end  of  four  or  five  years  clumps  become  so  densely 
matted  that  it  is  necessary  to  lift  then  for  the  purpose  of  division  and  subseciuenr 
thirjning. 


"'he  canna  after  being  placed  in  its  permanent  location,  \/hatever  that  may  be, 
can  be  left  there  indefinitely.  After  a  fe-.;  years  there  is  a  considerable 
-ncreaii^e  xn  one  airiount  aud  conceritraLloa  o±'   tlie  ■onuei'gro'und  root-scocK,  making 
the  group  very  dense.   If  the  concentration  of  plants  becomes  too  great  in  a 
given  area,  it  may  be  necessary  to  dig  that  particular  area  and  reset  In  order  to 
thin  out  to  the  desired  concentration.  This  should  best  be  done  in  the  spring 
before  active  growth  has  started.  They  should  be  t-eset  imrAediately. 

Fatso.iis,  is  another  of  the  bulbs  siirdlar  to  the  gladiolus.  Its  requirements 
for  harvesting  and  storing  are  the  sanie.  The  Calla  lily  is  a  plant  not  related 
to  the  lily  family  at  all  as  it  is  a  tuber  instead  of  a  bulb.  However,  it  io 
usually  classed  or  grouoed  with  the  flov;ering  bulbs  as  its  manner  of  grov/th  and 
flowers  is  somewhat  similar.  It  produces,  after  a  tirrie,  a  dense  mat  of  titters. 
These  should  be  left  undisturbed  -unless  it  is  vdshed  to  start  the  plant  in  some 
new  location. 

Briefly  summing  up,   specially  as  '..hen  tl.o  lifierent  kinds  of  bulbs  should 
be  dug:   In  general  narcissus  are  dug  each  .year  after  they  begin  to  yellow  and 
before  the  summer  rains.  'Thty  should  not  be  left  in  the  sun  after  being  dug,   and 
should  be  stored  in  a  cool,  dry,  well  ventilated  place. 

Gladioli  and  7/atsonia  are  usually  dug  when  the  tops  begin  to  die  dovm,  but 
may  be  left  in  the  ground  for  several  years.  Easter  lilies  need  to  be  lifted  only 
every  two  or  three  years,  but  the  job  should  be  done  before  rooting  starts  in 
late  August  or  September,  and  they  should  be  bedded  immediately. 

Among  the  bulbs  that  are  left  undisturbed  unless  it  is  desired  to  move 
them,  to  new  locations  are  Amaryllis,  Day  lilies,  Crinuras,  Cannas,  and  Calla  lilies. 
Snowflakes  are  usually  left  undisturbed  for  a  number  of  years,  and  Montbretias 
are  best  left  in  the  grouni  for  two  or  three  years.  Freesias  should  be  moved 
■"""ery  foxir  or  five  year<^. 

Thus,  we  can  see  that  the  different  b-.-..lbs  require  quite  different  conditio.-i-:. , 
and  that  it  is  up  to  gardeners  to  learn  those  requirements  if  they  are  to  be  able 
to  properly  dig  and  store  or  otherwise  handle  bulbs  and  have  them  ready  for 
abundant  bloom  the  next  blooming  season.

THE  LILIES  OF  A  MY 

By  H.  Harold  Hume,  assistant  director,  research 
Florida  Agricultural  Experiment  Station 


By  way  of  introduction  it  is  worth  noting  that  the  eastern  parts  of  Asia  — 
China,  Japan  and  adjacent  areas  more  particularly  —  have  contrihuted  greatly 
to  the  beauty  of  Florida  gardens.   Indeed  if  we  were  to  remove  from  our  state  all 
tl-0i2e  plants  that  have  cor.e  directly  fro:r.  V~c   Far  East  or  that  trace  hack  to  f--.-!. 
source,  the  orange,  rose,  chrysa.nthenr,m,  azalea.,  pittosporum,  camellia  and  mary 
others  would  disappear.   So,  too,  v;oiild  go  the  daylilies,  a  lovely  group  of 
herbaceous  perennials  that  we  are  t-  consider  at  this  time,  for  they  or  their 
progenitors  came  from  the  same  regica,   Im  that  portion  of  the  world  they  have 
been  highly  regarded  since  long  ago  as  garden  and  food  plants. 

To  the  botanist  they  are  known  by  the  name  Hemerocallis  (He-mer-o-cal'-lis)  .. 
which  literally  means  "beauty  for  a  day,"  and  are  often  referred  to  as  "fhe 
lilies  of  a  day"  in  reference  to  the  fact  that  the  individual  flowers  last  but  a 
single  day  or  thereabouts.   In  our  gardens  s.re   many  ornamentals  that  we  refer  to 
as  lilies  that  really  do  not  belong  to  the  lily  family,  but  the  daylilies  are 
classified  in  the  lily  gronp. 

The  first  we  Imow  a'^out  th' m  dates  back  to  a  boo?-:  published  in  Europe  in 
1570,  when  one  of  them  wps  illustrated  in  "Fistiria,"  a  work  on  plants  written 
by  Pena  and  Lobel.  This  particular  variety  is  the  yellox'';  daylily.  A  period  of 
I83  years  passed  by  until  Linnaeus  (Linn-e'-vs) ,  the  father  of  modern  systematic 
botany,  gave  it  a  botanical  name,  Hemerocallis  flava.   In  the  meantime  it  had 
gone  into  many  gardens,  and  being  naroilfss-  iindoubtedly  it  was  known  iy   such  de- 
signations as  "the  lily  from  Berlin,  "the  ont  that  Aunt  Marj''  gave  me,"  or'"bhal. 
yellow  thing  that  I  have  in  the  garden,"  —  just  as  plants  of  different  sorx.s 
are  known  to  many  even  to  this  day. 

Linnaeus,  who  gave  a  name  to  the  yellov;  dajrlily,  also  described  and  nam^c. 
another,  Hemerocallis  fulva,  the  tavmy  daylily.   This  is  a  remarkable  perem;L:.l, 
for  though  under  all  usual  conditions  it  never  prodiices  seed  it  has  been  know;i 
in  gardens  for  centuries  and  has  made  its  way  about  the  world  simply  through 
being  divided  into  pieces.   In  abandoned  Ames>-ican  gardens  it  has  persisted  anl  i"' 
has  become  established  as  a  wildling  froin  material  cast  aside  in  garden  niakxii^^. 
For  mar^  years  these  appnrently  were  the  only  daylilies  known,  but  as  time  went 
on  and  contacts  with  the  Orient  widened  other  kinds  were  introduced  and  by  the 
year  I9OO  eleven  species  and  varietlz-s  were  listed  by  the  Cyclopedia  of  American 
Horticulture.  Today  thirteen  wild  forms  or  groups  of  forms  have  been  recognized 
and  described  by  botanists.   In  recent  years,  to  be  more  definite,  since  I9OO, 
several  plant  breeders  —  Betcher,  I?.rr  and  Stout,  in  A:nerica,  and  Yeld  aid  Perry 


-2- 


in  England,  and  others  elsewhere  —  have  interested  themselves  in  the  daj'-lilies 
to  such  an  extent  that  throngh  cross-breeding  and  selection  there  are  now  more 
than  150  named  sorts,  dwarf,  medim.i  and  tall;  pale  j'-ellow,  golden  yellow, 
copper-colored,  ta-.vny,  mahogany  hrovm,  pink  and  red;  with  petals  of  different 
shapes  and  sizes,  variously  marked  —  a  truly  wonderful  assortment  of  lovely 
varieties,  BeautifiJ  though  the  varieties  we  have  nov;  are,  the  future  without 
douht  holds  new  combinations  of  colors  and  new  forms  that  will  surpass  them. 
Here  at  the  University  of  Florida  many  seedlings  resulting  from  crosses  made  by 
John  Watkins  are  now  really  for  the  test  grounlR,  The  collection  in  the  Agri- 
cultural College  garden  numbers  about  one  htindred  at  this  time. 

Daylilies  are  dependable  garden  plants  for  Florida  gardens.  They  may  be 
grown  all  the  ',vay  from  the  Georgia  boundary  to  the  areas  south  of  Miami  and 
east  and  west  throughout  the  state.  This  is  renarl-able  because  they  are  also  at 
home  in  the  cold  clirna,te  of  parts  of  Canada  and  the  various  northern  states. 
Hot  all  are  likely  to  be  equally  adapted  and  some  testing  and  selection  will 
need  to  be  done. 

The  daylilies  nay  be  divided  into  tv:o  groups,  one  evergreen  throughout 
winter,  those  of  the  other  group  losing  their  leaves  with  the  coming  of  cool 
weather.  Preference  with  us  F/ill  be  given  to  the  evergreen  sorts,  for  the 
deciduous  ones  may  not  be  adapted  as  widely  through  vfhere   they  do  succeed  they 
are  valuable  because  they  are  usually  low-growing  and  bloom  very  early. 

With  a  proper  selection  of  varieties,  daylilies  may  be  had  in  flower  for 
many  moiilfchs.  Here  at  Gainesville  t  ey  begin  in  March,  reach  their  peak  in  June 
and  end  in  August  or  September.  For  different  parts  of  the  state,  the  time  of 
flowering  will  vary,  earlier  or  later  depending  upon  the  seasons,  heat  and 
moisture. 

Evergreen  daylilies,  when  not  in  bloo;a,  furnish  good  compact  green  masses 
that  rest  upon  the  soil  and  rise  to  a  hei£;ht  of  several  inches,  even  to  two  feet 
or  more.  So  they  have  valii.e  in  the  garden  t-  at  for  r.any  purposes  mai:es  them  just 
as  valuable  as  evergreen  shrubs  of  many  sorts.  As  low  or  medium-sized  plants 
they  can  be  used  in  the  si. rubbery  border  ver;;--  satisfactorily. 

In' considering  the  "  eight  of  daylilies,  two  features  should  be  taken  into 
account,  the  height  of  the  mass  of  leaves  as  f/'jy  grow  in  clumps  and  the  height 
of  the  flower  stems  when  in  oloom.  As  a  rule,  the  early  flowering  deciduous 
varieties  have  leaf  masses  and  flo'-ering  stens  of  about  the  sair.e  height  while  the 
later  sorts  as  a  rule  produce  flower  stems  tr.-.t  rise  well  above  the  leaves.  It 
is  necessary  that  these  features  be  studied  as  it  will  not  do  to  set  low  ones 
behind  tall  varieties  when  arra^'iging  them  in  the  garden.  Fortunately  it  is  very 
easy  to  take  the  clumps  up  and  rearrange  them.  With  this  in  mind  such  varieties 
as  Orangeman,  Apricot,  Gold  Dust  and  Sovereign  are  dwarf  or  low-growing;  WaiiBun, 
Mikado,  Vesta  and  Cinnabar  grow  to  medium  height ;  while  The  Gem,  Queen  of  May, 
Aurantiaca  major  (Au-ran-ti'-a-ca)  and  Pulva  are  tall-growing  sorts.  The  height 
to  which  daylilies  will  grow  is  dependent  in  some  measure  upon  the  amount  of 
plant  food  provided. 

In  color  it  will  be  noted  that  the  color  range  is  wide.  PerhaiDs  this  can 
best  be  indicated  by  reference  to  certain  varieties.  Modesty  is  very  pale 
yellow,  Vesta  is  a  good  deep  orange-yellow,  Gold  Dust  is  reddish  brown  on  the 


-3- 


outside,  yellov;  on  the  side  of  the  flov/er,  ?ulva  rosea  is  rose-colored,  Mikado 
J  a  orange  v;ith  red  brovm  riiarlcings,  Aurantiaca  is  deep  orange  with  orange  red 
shading,  BroiTnie  is  mahogany  brown,  and  ?n.lva  is  orange  copper- red.  The  shades 
are  many  and  they  vary  with  the  lighting,  All  are  bright  and  attractive  in 
suitable  light. 

Most  daylilies  have  open  flowers  during  daylight  and  those  who  know  only  the 
oiaer  varieties  may  thinlv  that  d^-blooming  is  chax^acteristic.  But  this  is  Ti^t 
30,  for  there  are  daylilies  that  open  their  flovvers  at  night.  There  is  quite  a 
little  variation  in  the  time  of  opening  and  fading  of  different  varieties.   Some 
last  approximately  tvfenty-four  hours  from  the  time  of  opening  while  others  remain 
open  for  a  shorter  time.  Most  of  the  day-blooming  sorts  are  in  good  condition 
uiitil  about  midnight. 

Most  gardeners  are  looking  for  flov/ers  and  garden  subjects  that  are 
dependable  and  satisfactory  but  -.vhich  at  the  saiT.e  time  require  but  little  care. 
When  these  things  are  considered,  there  are  ie'.7  herbaceous  perennials  that  f-re  so 
free  from  insect  and  disease  troubles  and  so  easily  gro\7n  as  the  daylilies.   It 
would  be  hard  indeed  to  find  ornamentals  so  little  subject  to  the  troubles  that 
befall  many  garden  subjects. 

They  may  be  allo'ved  to  reiiiain  where  planted  for  several  years  and  all  that  is 
called  for  is-  a  few  handfuls  of  fertilizer  or  a  few  shovelfuls  of  stable  manure 
from  time  to  time.  Even  without  these  plant  foods  they  will  give  returns,  but  best 
results  are  secured  by  giving  them  food  and  water  as  needed.  Good  care  through 
the  summer  is  repaid  in  abundant  bloom  the  following  season.  At  least  once  a  year 
the  dead  leaves  should  be  cleared  away  and  when  the  flower  stems  have  finished 
their  crop  of  bloom  they  should  be  cut  axvay.   Sometimes,  too,  and  particularly  in 
small  plantings,  the  removal  of  faded  flowers  from  day  to  day  improves  the 
appearance  of  the  flowering  stems. 

Daylilies  may  be  grown  from  seed  v;ithout  any  particular  difficulty  but 
!-:peciraens  so  obtained  cannot  be  depended  upon  to  reproduce  true  to  tj'pe  or  fcnn. 
Gonsequentlj''  they  are  not  usually  grown  from  seed  except  bv  those  interested  in 
securing  new  and  different  varieties.  The  comraon  method  for  increasing  the  supply 
"f  a  variety  is  to  dig  up  the  clumps  and  cut  or  break  them  into  smaller  clumps. 
They  m^y  be  divided  so  as  to  separate  all  the  individual  shoots  with  a  few  roots 
t-.i''jached  and  each  of  these  will  raalue  a  new  plant.  This  is  best  done  during  -".he 
dormant  period  in  winter.   Shoots  with  leaves  and  even  roots  sometimes  develop  on 
•che  flower  stems;  these  may  be  tal:en  away  and  established  as  new  plants. 

While  it  is  true  that  daylilies  nay  be  taken  'p  and  set  out  at  aiiy  time  cf  th' 
year  it  is  really  best  to  move  them  in  winter  before  growth  starts.  TTnen  setting 
them  out,  the  soil  should  be  enriched  with  a  handful  or  two  of  commercial 
fertilizer  for  each  plant  and  they  should  be  watered  well  until  established.  Mai y 
of  the  daylilies  have  enlarged  or  swollen  roots  and  as  these  doubtless  hold  a 
considerable  amount  of  moisture  they  are  helpful  in  establishing  plants  when  newly 
set  as  well  as  in  tiding  them  over  periods  of  dry  weather. 

Here  is  a  list  of  good  sorts  most  of  ?/hich  should  succeed  in  Florida  gardens: 
Amaryllis,  Aurantiaca  major,  Bro'/mie,  Calypso,  Cinnabar,  Cressida,  Flava, 
Plorham,  Fulva,  Pulva  rosea.  Gold  Dust,   Gypsy,  Marga:-et  Perry,  Mikadc ,

Modesty,  Mrs.  A.H.  Austi.n,  Rosea,  Shirley,   Sir  Michael  Foster,  The  G-em, 
Vesta,   Wa-uBun. 

Within  recent  months  Dr.  A. 3.  Stout,  of  tie  llew  York  Botanical  Garden, 
Bronx  Pari:,  Hew  York  City,  who  for  a  long  time  has  been  interested  in  this  group 
and  who  has  produced  many  beautiful  sorts,  has  given  us  a  book  on  daylilies, 
published  by  the  Macmillan  Company,  in  which  the  varieties  listed  and  many  more 
are  described.   It  is  delightfully  written  and  should  be  in  the  hands  of  everyone 
interested  in  these  plants. 

In  China  and  Japan,  daylilies  are  a  source  of  food.  The  flower  buds  and 
young  shoots  are  cooked  while  the  petals  of  several  sorts  are  eaten  raw  or  dv'ied 
and  used  in  soups.   Indeed  in  parts  of  China  daylilies  are  gro'im  in  quantity  to 
pupply  flowers  for  food.  Dried  daylily  petals,  put  up  in  pound  and  half-pcjr.d 
packages,  imported  from  China,  may  be  purchased  in  Chinese  shops  in  the  larger 
cii/ies  of  America.  The  fresh  petals  have  a  slightly  pungent  taste.  'Vhy  net  io-.ke 
a  salad  that  would  catch  the  eye  at  the  same  time  it  \7ould  please  the  taste  — - 
green  lettuce,  deep  yellow  daylily  j.^tals  and  red  tomatoes!  TThat  a  color  schcniei 

As  cut  flowers  daylilies  are  valuable.  The  blooms  of  a  single  variety  may 
be  used  alone,  or  since  throiigh  thera  all  something  of  the  same  color  runs,  in 
different  shades,  several  varieties  may  be  "ised  in  a  single  decorative  compos;iti^r. 
Used  in  large  masses,  in  suitable  containers,  properly  lighted,  there  are  few 
flowers  that  can  surpass  them  in  a  show  that  while  striking  and  gorgeous  is  £;.t 
the  same  time  pleasing,  delicate  and  refined.   In  beauty  of  color,  in  curve  cf 
petal,  in  grace  of  carriage  they  are  distinct. 

The  statement  will  have  been  noted  that  the  flowers  of  daylilies  last  for 
oi:Lly  a  day.  For  that  reason  some  may  thinlc  that  they  are  not  worthwhile;  they 
pass  too  quickly.  But  if  a  scape  or  flowering  stem  is  ejcarained  it  will  be  noted 
that  there  are  a  large  number  of  ouds.  There  may  be  a  dozen  and  a  half,  for 
instance,  each  good  for  one  bloom;  so  there  pre  flowers  for  eighteen  days.  Since 
all  the  flov/er  stems  do  not  comie  at  once,  the  flowering  season  from  a  clump  f- 
one  variety  may  last  for  several  weeks.  There  is  something  of  value  in  the  thort. 
life  of  a  flower  that  is  replaced  day  bv  day  in  that  the  blooms  are  always  fresh, 
bright  and  gay.  There  comes  to  mind  a  glorious  sight,  seen  but  once,  never 
forgotten  —  white  fleecj''  cloii.ds  in  an  azure  skj'  on  a  suiilit  Florida  da''^,  a  field 
covered  with  a  mass  of  dark  green,  grass-like  foliage  over  which  danced  raj'^riait- 
of  glistening,  golden  flowers,  swaying  on  wandlike  stems,  changing  in  shade  e.s 
light  chased  shadow  across  the  scene  —  daylilies  in  bloom'.  And  then  to  thiii  "ihat 
all  that  beauty  faded  and  disappeared  before  the  rising  of  another  sun,  only  t  ■•  be 
replaced  by  a  scene  just  as  lovely,  just  as  bright,  just  as  golden,  yet  not  a 
single  flower  was  carried  over  from  one  day  to  the  next. 

"It  is  not  grov/ing  like  a  tree 
In  bulk,  doth  make  man  better  be; 
Or  standing  long  an  oak,  three  himdred  year. 
To  fall  a  log  at  last,  dry,  bald  and  sere: 
A  lily  of  a  day 
Is  fairer  far  in  I"ay, 
Although  it  fall  and  die  that  night  — 
It  was  the  plant  and  flower  of  Light. 
In  small  proportions  we  just  beauties  see; 
And  in  sho^t  measures,  life  may  perfect  be.'*

SOIffi  KEW  MD   OLD  PLMTS  OF  ilORIDA  GAEDEES 
W.L.  Floyd,  professor  of  horticulture, 
University  of  Florida  College  of  Agriculture. 

According  to  an  old  Jingle  a  bride  should  wear  on  her  wedding  day 

"Something  old,  something  new 
Something  borrowed,  something  blue". 

Most  of. this  applies  equally  well  to  gardens.   It  unquestionably  adds  variety  and 
interest  to  have  the  garden  contain  old  favorites  and  new  creations. 

The  old  ones  have  associations  and  memories  attached  tc  them;  grandmother's, 
a  favorite  aunt's,  or  some  very  dear  friend's  garden,  perhaps  in  a  distant  State. 
It  is  pleasant  to  be  reminded  of  these  as  we  waiider  in  the  late  c-^f  ternoon  pjnid  the 
beauty  and^ fragrance  of  our  own  garden.   I  have  some  that  are  constantly  suggestive 
of  the  choice  plants  of  a  grandfather,  some  of  whose  characteristics  I  ajn  said  to 
have  inherited.  Many  old  plants  are  interesting  because  of  their  history,  some 
be^.ause  of  the  name  of  the  discoverer  or  introducer,  others  because  of  the  place 
from  which  they  came,  or  the  Old  World  region  where  they  have  been  grown  so  long 
that  they  seem  ?>  part  of  it. 

The^rose  is  probably  the  oldest  cultivated  flower.   It  was  crowned  queen  of 
flowers  in  Athens  more  than  two  thousr<nd  ye^rs  ago,  and  long  before  that 'it  h''>d 
been  grown  .-^nd  admired.   References  to  it  are  foi^jid  in  many  ancient  writings,  both 
secular  ajid  religious.   It  is  grown  today  in  every  civilized  country  of  the  world. 

Helen  Fox  in  her  book  "Garden  Cinderellas",  a  treatise  on  lilies,  says: 
''Since  the  dawn  of  culture  among  the  people  of  central  and  western  Europe  lilies 
h^ve  been  knovvn  and  cultivated.  Among  the  Greeks  and  Romans  they  were  favorite 
flowers".   In  the  oldest  book  in  Arnold  Arboret\im,  published  in  Auchburg  in  1^-75, 
is  a  figure  of  the  Madonna  Lily,  which  shows  that  this  variety  was  appreciated 
centuries  ago. 

Miss  Fox  pays  this  tribute  to  them.   "At  the  twilight  their  fragrance  calls  us 
into  the  garden;  as  the  rosen,  petunias  and  other  colored  flowers  gradually  fade 
out  in  the  gathering  dusk,  the  white  lilies  stand  out  like  friendly  ghosts". 

Florida  has  many  varieties  of  lilies  introduced  from  various  p.-^rts  of  the 
world.   Some  coming  from  the  Tropics  will' thrive  out-of-doors  in  Florida  as  nov/here 
else  in  the  United  States.   There  are  many  lily-like  plants,  often  called  lilies  — 
as  Crinum,  Eucharist  (Yu-cha-rist),  Amaryllis,  that  are  favorites  here. 

The  Oler'nder,  so  abundant  and  easy  to  grow,  almost  continuously  in  bloom, 
contributing  its  bright  hues  to  our  winter  Ipndsc'pe,  is  a  native  of  the 
Mediterranean  region  where  for  centuries  it  h^s  been  a  source  of  beauty  and 
enjojrment.

The  Jasmines  with  their  fragrant,  star-like  flowers,  are  abundant  in  our 
foundation  plantings,  borders  and  gardens.  Many  of  them  came  from  Arabia,  we  know 
not  how  long  ago,  showir^  how  the  uttermost  parts  of  the  earth  have  contributed  to 
our  attractive  and  varied  ornamental  plantings. 

The  Camellia,  more  often  called  by  its  specific  name,  Japonica,  in  the  South 
is  named  after  Camellus,  a  Moravian  Jestiit  who  travelled  in  Asia  in  the  seventeenth 
century.  How  long  it  had  grown  where  he  founi  it  and  brought  it  bad:  to  his  people, 
we  do  not  knov:;.  It  has  been  grown  since  Colonial  times  in  South  Carolina  and 
G-eorgia,  and  was  early  introduced  into  Florida  where  it  thrives  in  unsurpassed 
vigor  and  beauty.  Everj''  native  Southerner  feels  that  this  is  a  plant  of  true 
Southern  memories  and  associations. 

One  naturally  thinlcs  of  the  evergreen  Azaleas  along  with  Camellias,  as  they 
are  so  generally  planted  together  in  old  Southern  gardens.  The  varieties  coming 
from  Iniia  are  our  oldest  forms  and  give  us  a  wealth  of  pinlz  and  red  bloom  in  late 
winter  and  early  spring,  to  which  v;e  have  later  added  new  kinds  of  striking  beauty, 
from  Japan  and  China. 

There  are  several  old  woody  plants,  that  have  a  place  in  Florida  gardens. 
Spirea  or  Bridal  Wreath  is  one  of  them.   It  comes  from  Greece,  where  the  name 
Spirea  (meaning  band  or  garland)  v;as  given  because  of  its  use  in  crowning  heads  of 
beauty  or  valor. 

Another  is  hibiscus  or  Hose-Mallow.   It  is  like  the  Oleander,  almost 
continuously  in  bloom,  and  contributes  wonderfully  to  the  brightness  and  color  of 
Florida  in  printer. 

Still  another,  hydrangea,  a  rather  coarse  but  colorful  old  plant,  is  well 
suited  to  partial  shaded  positions. 

An  old  English  book  on  garden  flowers  that  I  have  been  reading  recently  calls 
hardy  perennials  'old  fashioned  flo'.vers' .   This  is  more  true  for  the  gardens  of 
England  and  those  in  this  country  established  in  Eew  England  arxi  other  colder 
climates,  than  in  Florida,  probably  because  where  there  is  snow,  ice  and  frozen 
ground  during  the  winter,  the  plants  store  up,  d\;rirg  the  summer,  nourishment  in 
fleshy  parts  underground.  They  protect  the  eyes  or  buds  with  hair-like,  downy 
or  scaly  coverings,  and  allow  their  more  exposed  tender  parts  above  the  ground  to 
die  at  the  close  of  the  growi  rg  season.  After  the  long  v;inter  rest  the  buc's  awake, 
and  drawing  on  the  stored  food  in  nearby  parts,  grow  rapidly  and  produce  the  first 
tender  leaves,  which  are  soon  followed  by  flowers  in  early  sprin,g.  ^e  have 
perennials  in  Florida,  but  thej''  behave  differently  and  give  us  summer  and  fall 
flowers  usually. 

The  most  conspicuous  new  flowers  of  Florida  gardens  are  among  the  annuals, 
because  it  is  so  much  quicker  and  easier  to  make  crosses  of  varieties  which  have 
promising  characters  and  may  give  new  and  desirable  combinations  if  blended,  — 
the  first  step  toward  the  goal  may  be  made  in  one  season.  Each  year  the  cata- 
logues bring  to  our  attention  neiv  forms  of  old  and  well-knoiTn  favorites,  much 
improved  by  breeding  and  selection  over  the  familiar  ones. 

An  illustration  is  v/hat  has  been  done  with  the  Zinnia.  One  does  not  have  to 


-3- 


be  very  old  to  remember  when  Ziimias  were  just  Old  Maids  rith  a  cone-like  center 
surrounded  by  a  single  circle  of  colored  petals.  One  after  another  have  appeared 
Mammoth,  Ficotee,  Curled  and  Crested,  Dahlia  Flowered,  Cactus  Flowered,  Pompon, 
Mexicana,  Early  'bonder,  and  others. 

The  Aster,  an  old  favorite,  has  added  new  colors,  sizes  and  more  disease- 
resistant  strains  to  Baby's  Breath,  new  rose  and  carmine  colors  has  been  added  to 
the  original  white.  To  the  golden-hued  California  Poppy  has  been  added  creams, 
whites  and  reds.  Larkspur  has  new  double  flowered  varieties  of  different  colors. 
Lupine,  now  has  larger  flowered,  longer  spiked  forms. 

To  keep  posted  regarding  new  Icinds  one  must  examine  carefully  each  winter  the 
current  flower  catalogues  and,  lest  some  recent  introductions  be  overlooked,  read 
regularly  a  good  garden  magazine. 

Suppose  we  run  through  the  seed  catalogues  for  the  last  two  years  aM  pick  out 
some  of  the  new  gardening  plants  they  offer.   In  the  catalogues  of  last  year 
there  are  a  number  of  new  and  improved  varieties  that  we  might  try. 

One  of  these  is  the  Ouinea  Gold  marigold.   It  grows  up  like  a  pyramid  and  is 
2  to  2|  feet  tall.   It  bears  semi-double  flowers  that  are  2  to  2^  inches  across. 
.".fly  are  broad,  ha-ve  wavy  petals  and  are  orange  and  gold  in  color.  The  flowers 
h..7e  a  less  pungent  odor  than  other  sorts  of  iTiarigolds. 

Golden  Gleam  nasturtium  is  one  of  the  1933  introductions  that  has  proven 
p-pular.  This  variety  of  nasturtiums  has  large  double  flowers  that  are  from  Sg- 

•  3  inches  across.  They  are  very  fragrant  and  are  golden  yellow.  Among  the 
J  .ters,  we  could  mention  the  new  wilt-resistant  and  peony-flowered  kind.  And,  if 
y-u  grow  lupines,  you  should  try  the  new  Hartwegii  giant  kind.  They  grow  3  to  U 
feet  tall,  have  base  branching  habits,  and  bear  U  to  6  long  spikes  to  the  plant. 
Each  spil^E  has  many  more  blooms  than  the  regular  Mnd. 

Then,  there  is  a  new  Dianthus,  the  hybrid  Street  Wivelsfield,  and  other  hybrids 
much  superior  to  the  old  forms.  Among  the  pansies,  there  is  the  Swiss  Alpenglow 
(Al-pon-glow)  and  several  new  giant  forms.   The  verbena  is  an  old  garden  favorite, 
and  Lavender  Glory  is  one  of  the  newer  kinds.   It  often  has  f levers  that  are  an 
inch  or  more  in  diameter.  Then  there  are  the  Beauty  of  Oxford  Hybrids  with  many 
shades  of  large  blooms  in  rourd  trusses. 

Another  gardening  plant  that  we  might  add  to  the  1933  new  introductions  is  one 
from  South  Africa.   It  has  rich  orange,  daisy-like  flowers  and  goes  by  the  name  of 
V:' nidi  am  fastuos-um  (Ve-nid'-i-um  fas-tu-o-sum)  . 

If  you  will  pick  up  a  I93U  catalogue  you  will  fine,  a  still  greater  array  of  n-jv? 
fj.owering  plants.   I  can't  help  but  mention  several  of  the  now  hybrid  petunias. 
The  California  Hose  is  one.   It  is  a  heavily  ruffled  petunia  that  is  rose  colorerl 
and  veined  with  white.  The  Mauve  Queen  is  another  one  that  is  beautifully 
frilled,  and  it  is  mauve  with  a  center  of  purple.  Pink  Pearl  is  a  l^rge  pink  tyj^e 
with  strongly  veined  centers,  and  the  Pihlc  Empress  is  a  new  one  that  is  deeply 
fluted,  heavily  fringed,  and  one  that  is  a  rose  pink  with  a  golden  throat. 
Another  with  rose  pink  fringed  flowers  is  the  Setting  Sun,  and  this  type  grows  as 
compact  plants. 


Among  the  newer  double  fringed  petumas  there  are  three  that  we  should 
mention.  The  Madonna  vrith  deeply  fluted  pure  -vhite  flowers,  the  Bizarre  with  a 
combination  of  rose-pink  and  white  in  striped  effects,  and  the  Rose  Queen,  a 
large  deeply  friiiged  rose  pinlc  kind. 

Tlie  Calendular  has  grown  to  be  one  of  our  most  planted  annuals,  and  the 
193^+  catalogues  bro'ight  us  several  new  kinds.  One  is  the  Chrysantha  or  Sunshine 
wi-'/h  large  double  flowers  of  golden  canarj'  yellow  that  are  borne  on  long  stout 
stems.   The  petals  are  long,  broad  and  drooping  which  gives  the  flower  a 
globular  form.  Another  new  Calendula  is  the  Sun  G-leam.   It  has  a  tangerine- 
orange  color  T/ith  a  brown  eye ,  and  the  petals  are  slightly  edged  with  brown.  Then, 
there  is  the  Topaz  with  double,  whitish  flowers  that  have  sulphr.r  yellow  tips. 

Another  new  annu/il  v^ell-rorth  your  trial  is  the  Chrjisanthemum  flowered 
poppy.   It  is  salmon  pink,  large,  and  lasts  well.   If  you  vrant  a  double  bloom  that 
is  a  rich  crimson  carmine  you  might  add  the  Carmine  Queen  variety  of  Eschscholtzia 
(Esch-Bcholtz'-i-a) . 

Among  the  well  liked  scabiosa  we  find  a  couple  of  new  types.  One  with  large, 
attractive  flowers  that  are  rosy-lilac  is  the  C-randiflora  Cattleya  (Gran-dif-lo'-ra 
Catt-ley'-a) .  Another  is  the  Doiable  Tall  Blue  Coci:B.de.   The  flowers  are  a  deep 
nsure  blue,  and  they  are  so  deep  as  to  be  almost  conical  in  shape. 

Those  v;ho  like  Delphinium  should  v/elcome  the  new  pure  white  Iceberg,  a 

variety  that  comes  true  from  seed.  And  those  who  have  been  growing  the  white 

Saby's  Breath  or  G■y]^hsophila  (G-yp-soph'-il-a)  should  try  the  rose  pinlc  variety.   It 
is  a  little  later  than  the  white. 

For  a  large  steel  blue  flower  one  of  the  iiewest  is  Iiinum  narbonense  (Li'-num 
nar~bo-nen'-se)  .  Among  the  Gaij.lardia  varieties,  there  is  S^anset  with  large  fine 
yellow  flowers.  This  is  an  unusually  beautiful  variety  of  this  well  ad.opted 
flower.  Aiid,  last  but  not  least  vie   might  mention  the  P-arple  Beauty,  a  new  variety 
of  Sweet  William.   It  is  a  bright  deep  purple  and  is  a  new  color  in  this  favorite 
flower. 

When  you  have  selected  from  this  large  array  of  old  and  new  plants  you  will 
have  something  old,  something  new  in  your  garden;  old  ones  for  their  quaint 
beauty  and  historical  values  and  new  ones  with  all  their  unusual ness  and  strikirjg 
colors.

Could  we  but  roll  back  the  eons  of  time,  it  indeed  \7ould  be  interesting  to 
review  the  development  and  spread  of  plant  life.  Were  the  large  trees  of  today 
always  huge  specimens  or  did  they  in  the  course  of  survival  find  it  necessary  to 
gradually  reach  higher  and  higher  to  obtain  the  sunlight  needed  for  existence^  And 
are  the  so-called  shade-loving  plants  adapted  to  shady  situations  because  they  were 
compelled  to  seek  shelter,  or  was  it  forced  upon  them^  Ard.  the  vines  -  were  they 
originally  small  shrubby  plants  that  had  not  the  strength  of  stem  to  compete  with 
trees  and  larger  shrubs  for  their  share  of  the  sun  but,  nothing  daunted,  developed 
the  ability  to  climb  by  twining  or  weaving  so  that  their  strongest  competitoro 
later  were  forced  to  become  their  means  of  support?  &reat  trees  may  be  the  monarchs 
of  the  forest  but  at  the  same  time  they  are  slaves  to  the  apparently  weak  vines 
that  reach  to  the  same  great  heights,  in  much  less  time,  by  utilizing  the  tree  trunlrs 
for  support. 

Vines,  in  their  habit  of  growth,  cannot  be  compared  to  shrubs  nor  to  trees,  but 
occupy  a  distinctive  place  in  the  plant  world.  Mother  Ifeture,  when  she  developed 
the  great  groups  of  plant  life,  gave  us  in  vines  a  tj/pe  of  plant  growth  for  which 
there  is  no  satisfactory  substitute.  Some  vines  may  be  effectively  grown  as  low 
phrubs,  some  shrubs  may  be  trained  as  small  trees,  and  some  trees  kept  pruned  to 
a  shrub-like  appearance,  but  few  iad.eed  are  the  other  plants  that  may  be  trained  in 
the  habits  or  appearance  of  vines. 

The  art  of  landscape  gardening  has  been  quick  to  recognize  the  merit  and  place 
of  gines  in  ornamental  planting  and  they  are  now  incliic'ed  to  no  small  degree  when 
suitable  subjects  are  available.  Their  habit  of  grow  on  iriakes  them  well  suited  for 
situations  where  neither  trees  nor  shrubs  are  adapted  or  are  satisfactory.  'Then 
properly  selected  vines  tend  to  lend  contrast  and  character  and  supply  a  finish  to 
plantings  that  can  be  attained  in  no  other  way. 

There  is  no'.v  no  question  as  to  the  desirability  of  shrubbery  plantings  about 
the  home,  but  there  is  still  the  q^'uestion  as  to  what,  how,  where  and  when  to  plant. 
It  has  been  most  aptly  stated  that  the  first  tendency  in  hone  planting  was  to  plant 
only  a  wreath  of  greenery  about  the  house  foiindation,  which  in  some  instances  gave 
the  appearance  of  a  house  set  on  a  feather  bed.  Slight  alterations  in  placing  the 
foundation  materials,  coupled  with  a  judicious  use  of  vines  and  trees  adapted  to  'Lhe 
conditions  involved  can  change  such  an  unsatisfactory  situation  inireasurably. 

The  old,  severe,  box-like  type  of  house  with  ornate  triramirigs  in  wood  or  iron, 
wherein  fancy  scroll  work  at  gaoles,  eoves,  verandas,  a.id  all  other  places  where 
such  could  be  fitted  in  or  tacked  on,  has  given  place  to  those  of  simple  but 
decorative  outline.  Greenery,  in  the  form  of  shrubs  and  vines,  is  used  to  improve 


-2- 


the  appearance  of  the  new  type  home,  and  care  in  planting  must  be  exercised  that 
architectural  features  are  neither  hidden  nor  emphasized  in  too  great  a  degree. 
Vines  here  play  their  part  and  can  be  included  to  advantage;  the  tightly  clinging 
sorts  that  may  be  closely  clipped  v;ill  accentuate  desirable  lines,  and  vigorous, 
rampant  growing  varieties  will  tend  to  obscure  harsh  features. 

T7ith  obeervation  and  some  study,  it  is  not  difficult  to  become  acquainted  with 
the  growth  habits  of  vines,  including  their  virtixes  and  faults,  and  to  thus 
determine  those  best  adapted  to  the  sitaation  aiid  the  effect  desired.   It  is  well 
to  bear  in  mind  not  only  the  desirability  of  the  vine  itself  but  as  well  the  effect 
it  will  produce  on  the  building  or  other  support  in  the  place  wanted.  Monotony 
and  lack  of  naturalistic  appearance  of  plantings  can  be  relieved  to  a  great  degree 
by  the  inclusion  of  vines.  Some  of  our  most  attractive  homes  owe  no  small  part  of 
their  charm  to  the  free-flowering  varieties  for  which  Florida  is  justly  famed.   It 
is  true,  of  course,  that  some  of  the  strikingly  flowered  varieties  may  not  be  in 
harmony  in  many  situations  and  with  all  types  of  buildings,  but  each  of  them  has  a 
fitting  place  in  combination  with  the  different  styles  of  architecture  and  the  many 
and  varied  garden  needs. 

Vines  are  especially  suited  to  ornamental  use  on  arbors,  trellises,  fences, 

pergolas,  verandas,  and  certain  places  on  bxiilding  walls.  Tree  truiics  are  well 
adapted  as  supports  for  some  varieties;  rock,  stucco  or  concrete  walls  for  others; 
and  heavy  wire  netting  of  coarse  mesh  is  particularly  suited  for  the  heavy,  woody 
kinds.  Vines  climb  by  means  of  twining,  weaving,  tendrils,  and  direct  attachment, 
so  that  regardless  of  the  type  of  support  there  is  a  variety  available  that  will  be 
found  admirably  suited.  3y  the  use  of  properly  adapted  varieties,  division  fences_ 
or  garden  walls  may  be  transforned  from  the  appearance  of  unsociable  barriers  to 
decorative  objects,  back  lot  enclosures  can  be  made  to  lose  their  una,ttractiveness, 
and  unsightly  objects  may  be  hidden  from  view. 

Usually,  the  beauty  of  vines  is  enhanced  when  the  plants  ha"e  an  immediate 
background,  and  the  better  effect  is  more  likely  to  be  attained  when  the  supporting 
trellis  is  closely  adjacent  to  a  building  than  when  placed  as  a  detached  object 
Bcmewhere  on  the  lawn, . 

Trellis  materials  and  construction  are  highly  important  since  a  weak  trellis 
will  be  near  a  state  of  collapse  at  aboat  the  time  the  vine  has  covered  it,  and 
repairs  then  will  be  difficult  if  not  impossible  without  major  damage  to  the  vine. 
Simple  but  strong  trellis  work  is  usually  preferable  to  a  complicated  pattern.   In 
placing,  it  should  be  free  of  the  wall  to  permit  ample  circulation  of  air,  and  at 
the  same  time  clear  of  the  drip  from  the  eaves.  Many  woods  are  satisfactory  for 
■'"ryllis  construction  but,  where  available,  cypress  is  :;/"ually  preferred.  All 
vT'derground  parts  should  be  thoroughly  soaked  in  creosote  or  other  wood  preservative. 
{.,nl   the  exposed  parts  well  painted.   If  of  metal  constraction,  only  galvanized 
Materials  should  be  used  as  rust  will  soon  destroy  unprotected  and  exposed  iron. 

Vine-covered  pergolas  are  becoming  miore  comimon,  and  in  their  construction  i'l'. 
is  r.eedless  to  saj'-  that  they  must  conform  to  the  style  of  the  house.  The  usage  cf 
p^r^'olas  is  mainly  as  a  connecting  or  a  terminating  decorative  feature;  they  oB^y 
connect  parts  of  a  garden  or  act  as  a  covered  passage  from  building  to  garden  but 
should  not  be  expected  to  serve  as  an  isolated  and  disconnected  garden  ornament. 
it  probably  is  unnecessary  to  add  that,  generally,  only  vigorous  growing,  rather 
heavy  vines  should  be  planted;  a  small  wealc.  vine  in  its  attempt  to  climb  and 
cover  a  pergola  of  fairly  large  dimension  is  more  grotesque  than  ornamental. 


-3- 


Transplanting  of  vines  from  the  open  ground  is  usually  done  during  the  \7inter 
months  although  potted  plants  and  some  of  the  more  tropical  kinds  may  be  moved  at 
any  season.  Thorough  preparation  of  the  soil  prior  to  planting  will  he  of  material 
help  in  securing  and  maintaining  a  vigorous  growth  in  the  plants.  Soils  should  he 
thoroughly  spaded,  not  only  deeply  but  over  a  wide  area,  that  the  root  system  may 
easily  spread  and  develop.   Incorporation  of  muck,  compost  or  other  litter  is 
recommended  for  sandy  soils.  Commercial  fertilizers  may  be  used  freely  and  to 
advantage.  Mixtures,  derived  in  part  from  organic  sources,  with  an  analysis 
approximating  U  to  5  per  cent  nitrogen,  6  to  8  per  cent  phosphoric  acid  and  3  ^o  5 
per  cent,  potash  will  be  satisfactory  in  most  cases.   Steamed  bone,  guano,  or 
tankage,  alone  or  in  combination,  will  a3aD  be  found  beneficial. 

With  most  vines  comparatively  little  pruning  is  required  other  than  to  keep 
them  within  bounds.  Rampant  growing  varieties  may  need  trimming  back  occasionally 
and  especially  so  when  growing  over  a  porch  or  on  the  walls  of  a  building.   Too 
much  or  too  heavy  vine  growth  in  such  instances  may  tend  to  give  an  appearance  that 
is  not  pleasing  and  an  impression  of  lack  of  balance  in  the  plantings.  Most 
flowering  varieties  are  pruned  shortly  after  the  blossoming  period  is  over  since 
late  pruning,  with  some  species,  will  remove  wood  that  produces  the  flower  buds  of 
the  next  season. 

Some  of  the  less  hardy  vines  are  not  adapted  to  statevvide  planting  because  of 
the  difference  in  minimum  temperatures  experienced  between  the  nortnern  and 
southern  sections.  No  definite  lines  separate  the  climatic  zones  of  Florida  but  in 
the  selection  of  varieties  it  must  be  borne  in  mind  that  many  of  them  cannot 
withstand  prolonged  lo-.v  or  freezing  temperatures.  The  hardiness  of  the  plant  in 
question  and  the  location  in  the  state  where  it  will  be  planted  should  be 
considered.   Several  local  factors,  other  than  latitude,  have  a  moderating  effect _ 
on  temperature  so  that  in  many  localized  areas  tropical  varieties  are  grown  that 
are  not  generally  adapted  to  the  area  as  a  whole.  The  loss  of  a  vine  by  freezing, 
however,  ife  not  usually  of  serious  consequence  if  the  roots  are  not  killed  for  it 
will  come  back  quickly  and  there  is  no  irnpairment  of  symmetry  as  may  be  the  case 
v/xbh  cold-damaged  ornamental  trees. 

There  is  an  exceptionally  wide  choice  of  vines  for  Florida  planting,  not  only 
of  those  adapted  to  a  given  type  of  support,  but  among  the  vines  themselves  there 
is  a  great  variety  of  both  foliage  and  blossom  in  size,  color  and  general 
appearance.  During  saxy  month  of  the  ;7ear  there  are  vines  in  bloom  in  some  part  of 
the  state.  Most  of  the  species  are  evergreen  which  maices  them  doubly  valuable  in 
that  their  beauty  and  utility  are  not  seasonal  but  present  throughout  the  year. 
Some  deciduous  sorts,  however,  because  of  their  striking  blossoms  or  other  very 
desirable  characters,  are  worthy  of  space  in  many  plantings. 

Those  parts  of  the  state  which  are  less  subject  to  heavy  frosts  are 
especially  fortunate  in  having  a  climate  that  i-all  permit  the  growing  ,  under 
Q.'.', -of-door  conditions,  6f  many  varieties,  that  are  not  known  in  more  temperate 
regions  except  as  greenhouse  specimens.  Included  in  this  group  of  tropical  Bpe;:'ev 
are  some  which  have  very  striking  and  unusual  foliage  and  bloom.   The  less  comraor 
varieties  are  al?;ays  a  source  of  interest  and  favorable  comment  and  the  opportuii."ty 
of  including  them  in  the  garden  planting  should  not  be  neglected  in  the  only  area 
in  the  United  States  where  they  can  be  grovm. 


-l]_ 


The  choice  of  varieties  for  ornamental  planting  is  almost  unlimited,  there 
"being  over  79  species  or  sub-species  of  perennials  in  the  state  as  well  as 
numerous  annuals  that  are  ideally  adapted.  Lack  of  time  does  not  permit  the 
naming  of  these  many  varieties,  much  less  describing  even  a  fev;  of  them..   The 
available  kinds  extend  over  a  wide  range  of  evergreen  and  deciduous  sorts.   They 
vary  from  dainty  twiners  to  heavy  woody  types;  from  those  with  small  foliage  to 
ones  having  huge  leaves  tvro  feet  in  length;  and  from  miniature-flowered  plants 
to  climbers  whose  blossoms  are  six  inches  across.  The  range  of  color  in  the 
blossoms  is  unusually  great;  it  includes  various  shades  of  orange,  red,  crimson, 
pin^,  white,  blue,  lavender,  violet,  buff,  yellow  5tnd  brown.  The  exceptionally 
wide  variety  of  ornamental  vines  available  to  the  Florida  gardener  provides  a 
suitable  climbing  plant  for  nearly  any  situation  where  a  climber  is  desired. 

Bulletin  188  of  the  Experiment  Station  lists  numerous  perennial  species  of 
ornamental  vines  and  furnishes  information  as  to  their  appearance,  grov/th  habits, 
adaptability  eind  culture  in  Florida.   Those  interested  in  the  subject  may  obtain

THE  SIMPLE  THINGS  IN  GARDENING 

H.  Harold  Hume 
Assistant  Director  Research 
Florida  Agricultural  Experiment  Station 

In  the  making  of  our  gardens,  we  so  often  overlook  the 
simple  little  things.   Many  who  profess  to  be  great  lovers  of  a  garden, 
of  growing  and  flowering  plants,  have  very  little  conception  of  the 
constant  details  necessary  in  the  having  of  these  things.   Gairdening 
is  far  more  than  the  setting  of  a  little  grass  or  the  planting  of  a 
few  seed.   We  humans  have  to  eat,  drink  and  dress  regularly,  and  we 
should  expect  no  less  of  the  living  plants  in  our  garden.   These 
little,  simple  details  make  the  difference  between  many  a  garden  of 
joy  and  beauty  and  similar  spots  that  are  failures.   They  are  like  the 
pennies  that  make  dollars;  they  add  up,  and  one  by  one,  day  by  day 
they  make  gardens. 

For  many  years  correct  information  han  been  available  and  has 
been  given  out  on  the  simple  subject  of  how  to  plant  trees.   And  yet, 
in  Florida  this  past  winter  ev3ry  rule  of  proioer  and  right  handling 
hds  been  broken  along  the  highways  of  the  state.   Roots  have  been  un- 
duly exposed,  tops  left  unpruned  and  undefoliated, "trees  have  been  set 
loosely  and  too  deep.   If  there  was  anything  that  could  be  done  wrong, 
it  was  so  done.   Go  into  our  towns  and  villages  and  note  the  tree 
butchery  that  passes  under  the  name  of  prunning .   We  wonder  whether 
the  simple  rules  of  how  to  prune  a  tree  will  ever  get  home  to  those 
who  have  such  work  in  charge.   It  is  just  as  badly  done  as  though 
those  doing  it  had  never  seen  a  tree  before,  and  the  worst  of  it  is 
that  it  is  no  more  costly  to  do  the  job  right  than  it  is  to  do  it 
wrong.  Valuable  trees  are  being  dpjsiaged  in  ignorance  and  their  lives 
shortened.   Why  shouldn't  this  necessary  job  be  done  right?  Why 
shouldn't  branches  be  removed  without  splits,  ?;ith  smooth  clean  cuts, 
close  back  to  the  branch  or  trunk  from  which  they  start?  Why  shouldn't 
the  cut  surfaces  be  painted  with  a  good,  cheap  asphalt  paint,  to  pre- 
serve the  wood,  to  keep  water  out  and  to  prevent  decay?  Maybe  some  day 
we  will  realize  tha.t  pruning  is  niit  a  job  for  those  who  are  ignorant  cr 
Careless. 


Along  the  saxae   line,  what  about  the  trees  and  the  pruning  in 
our  ovm  gp.rdens.   The  pruning  of  shrubs  of  different  kinds  is  woefully 
neglected.   Usually  it  is  too  long  delayed.  From  time  to  time  begin- 
ning a  fexv  months  after  planting,  shrubs  should  be  pruned  to  keep  thorn 


within  reasonable  bounds .  They  should  not  be 
off,  or  making  them  flat  on  top.  They  should 
naturally  and  to  this  end  they  must  be  pruned 
natural  form  or  habit.   This  can  best  be  done 


barbered  by  rounding  tLern 
be  allowed  to  grow 
so  as  to  preserve  their 
by  cutting  off  the 


-  2  - 

branches  down  in  the  heads  of  the  shrubs,  taking  them  out  here  and 
there  in  such  a  way  as  to  Ic'.ive  the  tops  natural  and  irregular  in 
outline. 

The  care  of  the  garden  should  begin  before  it  is  planted. 
Good  soil  is  the  lounda.tion  of  all  good  gardens  and  things  may  be 
done  to  the  earth  better  before  plants  are  set  out  than  can  ever  be 
done  afterward.   VJhen  the  garden  is  planted  th©  work  put  into  soil 
preparation  docs  not  show.   Two  areas,  the  one  poorly  prepared  and 
poorly  done,  the  other  with  soil  well  supplied  with  humus,  well  dug 
and  fertilized  and  properly  drained,  m&y  look  exactly  alike.   The 
difference  between  the  two  sho7TS  up  afterward.  The  well-made  garden 
will  make  its  way  in  spite  of  unfavorable  seasons;  it  will  grow  and 
thrive,  look  well  and  give  satisf 3.ction;  it  will  require  but  little 
attention  except  for  water;  it  will  be  a  joy  and  a  pleasure.   But  if 
the  ground  has  been  poorly  prepared,  if  it  is  lacking  in  hu^nus  and 
fertility,  the  plants  placed  in  it  "rill  become  unthrifty  and  will 
require  much  more  la.bcr  and  expense  to  maintain.   The  garden  mil  not 
reach  a  state  of  setisf  actory  do\'Olopment .   Then  prepare  the  soil  wel" 
giving  particular  attention  to  the  incorporation  of  vegetable  matter 
in  the  form  of  peat,  rotted  le-.-v.js,  leaf  mold,  and  thoroughly  decayed 
stable  manure.   For  our  soils,  an  applicption  of  three  or  four  inches 
of  such  materials  as  these,  well  mixed  with  the  top  eight  inches  of 
natural  earth,  will  work  wonders.   If  the  soil  is  very  light  and  poor, 
m.ore  vrlll   be  advisable.   It  may  b-i;  de^^irable  '.o  remove  the  original 
soil  and  replace  it  with  a  made-up  soil  of  ;■  od  composition. 

Vifatering  is  a  simple  operation  and  yet  how  frequently  neglec- 
ted, how  niggardely  done.   You  must  remember  thirt  all  the  food  and 
all  the  materials  that  a  plant  gets  from  the  soil  are  taken  up  in 
liquid  form.   It  follows  then:  no  water,  no  food;  no  food,  no  growth. 
There  must  be  wa.ter  in  the  soil  that  the  roots  may  take  it  up  to  fill 
out  the  Plant's  cells  and  to  carry  into  the  plant,  through  the  roots, 
plant  food  for  growth.   In  watering^rden  plants,  water  thoroughly. 
Water  an  inch  deep  applied  to  the  la^-i,  to  a  shrubbery  border,  orto 
a  planting  of  roses  or  zinnias  or  anything  else  will  do  a  lot  of  good 
during  a  dry  season.   But  if  that  same  inch  of  water  is  split  into 
eight  parts  and  applied  on  eight  different  days,  it  may  be  entirely 
useless. 

There  is  no  general  rule  to  be  follov/ed  in  applying  water  to 
outdoor  plants.   The  gardener  must  le;:,rn  to  know  his  plants  and  thei.: 
behavior,  and  to  watch  for  the  first  symptoms  of  distress.   Wiltinj- 
may  be  checked  by  merely  sprinkling  the  tops,  but  if  the  soil  is  dry, 
permanent  relief  can  be  secured  only  by  soaking  the  soil  thoroughly. 
Flaiits  recently  set  should  be  watched  ca.refully,  and  in  the  case  of 
trees  and  shrubs  more  water  than  usual  will  be  needed  during  the 
imrst  summer  following  transplanting,  because  their  root  systems  are 
limited  in  extent.   Then  these  require  water,  it  is  best  to  provide 
a  basin  in  the  soil  about  them,  fill  this  with  water  sev^^ral  times  and 
allow  it  to  soak  in.   In  addition,  the  tops  of  broadleaved  evergreen>?, 
transplanted  with  part  or  all  their  foliage  left  on,  should  be  sprin>- 
led  or  syringed  frequently.   In  fact,  it  is  e.   (^ood  plan  to  keep  them 
damp  aliiiost  constantly  until  they  are  e stab].:' shed.   This  checks 
transpiration  and  evapora.tion  ajid  keeps  their  moisture-content  at  or 
near  normal. 


-  3  - 

TlTater  applied  late  in  tlie  evening  oj  at  night  is  more 
effective  than  if  given  during  the  day  because  transpiration  fro:r.  the 
plants  and  evaporation  from  the  surface  of  the  soil  do  not  proceed  so 
rapidly  as  when  the  sun  is  shining.   It  has  been  said  that  plaaits  are 
da;naged  by  being  watered  vrhen  the  snn  is  on  them.   If  this  were  true, 
there  would  be  few  plejits  left  in  Florida.   Sprinkling  in  s^Jinshine 
may  be  injurious  at  times  to  tender  species,  but  thorough  watering 
can  result  only  in  good. 

For  good  root  development,  for  holding  water,  for  retaining 
and  furnishing  soluble  plant  food,  humus  formed  from  decaying  vegetab]' 
matter  is  a  necessity  and  no  g.^rden  soil  is  ever  satisfactory  without 
it.   Plants  have  to  be  fed  from  time  to  time  and  it  is  difficult  to 
secure  full  results  from  the  use  of  f or tilizt-iS  if  the  soil  is  lacking 
in  vegetable  matter.  Maintaining  a  good  cor.ij.j.st  heap  made  up  of  leave 
the  prunings  of  shrubs  smd  trees,  mold  from  tne  woods,  and  stable 
manure,  is  well  nigh  indispens?<ble.   Do  not  --aste  good  vegetable 
naterials.  The  ainoijuits  of  these  materials  that  go  to  waste  in  the  towr^ 
and  cities  of  Florida  every  twelve  months  is  appalling  ?jid  yet  a  glan-- 
at  plants  and  trees  that  are  city  property  indicates  how  vitally 
vegetable  matter,  that  could  be  supplied  from  this  source, is  needed. 

In  relation  to  c-^re,  the  dt?.ily  inspection  of  the  garden  is 
very  important.   If  the  area  is  small,  it  is  possible  to  inspect  all 
parts,  every  plant  in  it,  once  ev ^ry  day.   How  often  does  it  happen 
that  good  plants  are  lost  because  they  ha.ve  been  overlooked.'   In  an 
interval  of  a  few  days  they  have  suffered  for  lack  of  water,  insects 
may  have  gained  headway  and  destroyed  them.   It  is  often  just  as 
important  that  a  certain  piece  of  garden  work  be  done  on  time  as  that 
it  be  done  at  all.   Then  keep  a  careful  eye  on  the  garden  —  water, 
feed,  spray  on  time. 

Finish  in  the  grrden  is  important.   It  should  be  trim  and 
neat,  free  from  withered  flowers,  dead  leaves  and  branches.   How  oftc 
is  it  the  C3.se,  following  the  cold  periods  that  sometir.ies  come,  that 
dead  branches  or  whole  plants,  their  leaves  withered  and  unsightly, 
are  left  standing  for  days  and  wejks.   In  the  interest  of  the  finish 
of  the  garden,  they  should  be  remo/Bd  and  all  signs  of  distress  re- 
moved quickly.   Then,  too,  v/alks  -:.nd  edges  should  be  trimmed  and  the 
grass  mowed.  You  and  I  need  a  haircut  now  and  then  —  so  does  the 
lawn. 

If  it  has  not  been  done  yet,  the  I'j  n  should  ho.ve  its  spring 
?.p-oliGation  of  fertilizer  right  away.   Put  on  a  good  application  of 
a  balanced  fertilizer  rich  in  ammonia  or  of  cottonseed  meal,   Ptit  it 
on   at  the  rate  of  a  half  ton  to  the  acre,  wuich  means  two  and  one-hai' 
I.-'junds  to  one  hundred  square  feet,  and  wash  it  down  into  the  grass. 
"■ater  as  needed  and  when  the  lam  is  mo'^ed  do  not  cut  it  too  closely- 
it  is  not  good  for  nunning  grasses  to  be  mowed  so  as  to  expose  the 
prostrate  stems. 

It  must  be  emphasized  th.at  the  care  given  plants  at  one 
season  of  the  year  is  reflected  in  their  behavior  many  months  later* 
The  price  which  wc  must  pay  for  flowers  and  gro-"th  in  the  spring  of 
1934,  for  instance,  is  the  food,  water,  protection  and  care  that  v-e 
give  the  plants  now.   If  there  is  good  growth  and  good  food  storage 


_  4  - 


during  the  su:"mer  and  fall  of  this  season  in  perennial  plants,  then 
reward  will  come  in  wealth  of  bloora  the  follovring  spring.   Again,  in 
handling  bulbs  in  the  garden,  gladiolus  or  narcissus,  for  instance, 
gardeners  too  frequently  fail  to  realize  that  the  care  and  attention 
must  not  cease  with  their  flowering.   Aftor  that  tine  they  should  have 
needed  Tvater  and  plant  food,  potash  and  phosphoric  acid  in  particular, 
until  they  have  fully  matured  aaid  their  leaves  die  dovm.   What  you 
get  out  of  your  garden,  of  interest,  of  health,  of  joy,  of  plants,  of 
flowers,  '-/ill  be  in  direct  proportion  to  what  you  put  into  it  of 
planning,  of  thought,  of  study,  of  comradeship  with  your  plants,  of 
yourself.   If  you  give  little,  your  reward  will  bo  proportionately 
Sir.all;  if  you  give  abundantly,  your  teturn  will  be  aiaple.   Ydu  may 
fool  yourself,  but  you  can't  fool  plants.

IIATUHAL  BEAUTI3S  OF   PLCEIDA  ROADSIDES  AW 
THE  IF.  CONSERVATION 
E.  Harold  Hume,  Assistant  Director,  Research., 
Agricultural  Experiment  Station 


Over  the  highT7a:<''s  of  Florida  there  has  come  r.   tremendous  change  in  recent 
years.  Indeed,  the  present  system  of  roads  is  a  development  of  a  short  period 
of  time,  as  the  years  are  measured.   One  may  travel  over  paved  highways  into 
almost  any  part  of  the  state,  and  journeys  to  many  points  may  be  made  by  any 
one  of  several  different  routes.  We  are  approaching  the  time  perhaps  v^hen  re- 
building and  maintenance  may  be  of  more  importance  than  new  construction.  As 
a  rule  the  roadbeds  are  well  graded  and  vvell  drained,  the  berms  are  protected 
by  grasses  or  other  107'-gro'.7ing  groiAiid  covering  plants,  the  ribbon-like  pave- 
ments lying  bet^veen  strips  of  green  present  a  pleasing  appearance.   The  higla- 
ways  of  the  state  are  a  basic  asset;  they  have  assisted  greatly  in  the  state's 
development,  and  they  can  be  made  of  still  greater  value  by  enhancing  and  pre- 
serving the  beauties  of  adjoining  areas. 

The  beauty  of  any  highway  is  affected  van'  definitely  by  the  country 
through  which  it  passes,  by  what  adjoins  it  on  either  side.  Tliere  are  certain 
roads  in  Florida  that  must  be  classed  as  unusual  —  perhaps  they  should  not  be 
classed  as  beautiful  in  the  ordinar?'-  sense,  but  they  are  most  interesting.  The 
beauty  of  Florida  roadsides  depends  not  upon  lofty  mountains  or  rolling  uplajids 
or  turbulent  stresjns,  biit  upon  views  of  placid  lakes  and  smooth  flowing  streams 
fringed  with  trees  and  shjrubs  and  lowly-growing  plants,  upon  stretches  of 
marsh  or  flat  pine  forests  gay  at  certain  seasons  with  a  riot  of  bloom  pecu- 
liar to  Florida  soil  and  climpte,  upon  glimpses  here  and  there  of  the  wind- 
swept ocean  or  the  rolling  Gulf.  I-Iore  than  ans'^thing  else  there  enters  into 
the  beauty  of  Florida's  landscapes  t':e  varied  plant  life  for  which  the  state 
is  justly  famjous.   It  adds  heiglit  to  hilltops,  it  fringes  lakes  and  ponds  and 
rivers,  it  covers  marsh  and  higher  ground,  it  floats  upon  the  surface  of  pla- 
cid lakes  and  streams,  it  covers  trunics  and  branches  of  vridespread  trees,  it 
hangs  in  festoons  from  swaging  branches,  it  covers  with  dense  impenetrable 
growth  the  lower,  moister  lands  and  shades  the  hig'-er  areas  with  open,  park- 
like growths  of  pine  and  other  trees.  Because  of  hese  special  features, 
Florida  is  a  beautiful  and  an  unusual  state.   Its  j.lora  makes  it  so.  To  the 
maintenance  ajnd  enrichment  of  this  natural  beauty  the  best  thought  and  action 
of  the  citizens  of  the  state  may  well  be  directed,  and  particularly  is  this 
important  as  related  to  areas  adjoining  our  highways. 

It  is  a  fair  statement  that  in  la"ing  out  and  building  the  highways  of 
the  state  much  of  natural  beauty  has  been  sacrificed  and,  I  regret  to  add,  a 
great  deal  of  it  needlessly  so.  Few  roads  have  been  projected,  surveyed  and 
built  with  the  scenic  beauty  of  the  route  definitely  in  mind.   If  proper  con- 


-  2 


sideration  is  given  to  the  basic  value  of  beautifiil  roadwajrs  and  roadsides  to 
the  state,  then  in  all  future  road  building  this  feature  rnust  receive  the  at- 
tention to  i?/!iich  it  is  entitled.  Every  proposed  right-of-waj'-  should  be  cri- 
tice.ll,y  exexnined  to  determine  '<ihr.t   of  beaut"  and  interest  maj;  be  rrade  acces- 
sible;, '^hat  of  notewortl'i;;'-  features  m^^'■  be  preserved,   ^^e  may  '7ell  consider  a 
curve  in  a  road  to  preserve  a  beautiful  group  of  trees,  we  may  well  put  a  bend 
in  a  ditch  to  save  a  specimen,  we  may  well  bring  a  road  up  to  the  top  of  a 
hill,  that  a  distant  view  may  be  secured,  we  itiay  well  swing  a  road  to  the  ma.r- 
gin  of  a  lake  or  the  border  of  a  n:ia.rsh  that  something  of  its  beauty  can  greet 
the  sye  of  the  traveler.   In  the  past  these  features  have  not  been  valued  at 
their  true  worth,  and  a  distinct  change  of  vieiirpoint  becomes  necessary.  Rail- 
road engineering  and  construction  has  been  the  background  of  highway  develop- 
m.ent.   In  all  seriousness  there  is  need  of  a  change  of  viewpoint,  ajid  vre   rnust 
have  a  highwa;?'  engineering  viewpoint  separate  and  distinct  from  that  of  rail- 
road building.   The  ideal  would  be  the  vision  of  a  landscape  engineer,  the 
next  best  would  be  the  opinions  and  views  of  a  thoroughly  trained  landscape  ar- 
chitect worked  into  the  plans.   That  there  is  developing  a  more  sjanpathetic 
attitude  toward  oiir  landscapes  is  excrrrplified  in  some  instances  of  road  build- 
ing, but  there  is  need  for  more  of  it.   It  is  of  primary'-  basic  importance  to 
the  welfare  and  future  development  of  Florida  that  these  ideas  be  given  full 
consideration. 

3ut,  these  suggestions  cannot  help  us  fully  with  roads  already  built.   To 
the  planting  and  iinprovement  of  them  much  thou^-ht,  discussion  and  effort  have 
been  given.   To  this  date  I  miist  say,  and  I  say  it  with  regret,  very  little 
has  been  axjcomplished.  Moreover,  I  have  the  feeling  that  attenTpts  along  pre- 
sent lines  arc  futile  and  little  of  value  will  come  of  them.  'To  have  planted 
tress  and  shrubs  along  the  open  highways  of  the  st' te,  and  what  is  there  to 
show  for  the  effort,  tine  and  money  expended?  As  co.rpared  with  the  great  ex- 
tent of  our  road  systam,  nothing.  Por  one  reason  or  another  we  have  failed. 
Tairf     Because  wc  have  set  trees  and  failed  to  give  them  necessar3'-  plant  food. 
^^e  have  put  them  in  the  ground  and  have  gone  away  and  forgotten  them,  '^e  have 
plaaited  them  and  failed  to  protect  them  against  fire.  Cattle  have  used  them 
for  scratching  posts;  one  thing  or  another  has  befallen  them  until,  in  the 
■cnain,   wc  have  nothing  to  show  for  what  it  was  hoped  might  result  in  great  iii>- 
provement . 

Before  much  can  result  from  roadside  planting  adequate  protection  must  be 
afforded  against  fire.   Tliers  must  be  ar.rple  provision  for  proper  maintenance 
after  planting,  at  leas:-  until  thoroughl;^  established.  Fater  majr  be  needed, 
fertilizer  is  req^oired.   It  must  be  someone's  job  to  give  necessary''  care.   In 
the  interest  of  highway  bea-.itification  and  safe  travel  as  well,  cattle  must  be 
excluded  from  the  highways.   I  do  not  blame  the  cattle;  the  road  berms  afford 
the  best  grazing  at  hand.   The  system  and  the  gonc-ral  point  of  view,  instead, 
are  at  faiilt.  Unless  the  conditions  indicated  can  be  corrected,  unless  ade- 
Quate  provision  is  rmde  for  maintenance,  unlsss  protection  is  ajfforded,  v/e  may 
Just  as  well  discontinu3  our  efforts  along  present  lines  until  these  -LUitoward 
conditions  are  corrected. 

Viewpoint  a.nd  treatment  must  change  and  the;''  will  change.  In  tlie  mean- 
time, that  is  until  the  results  from  -lantings  of  one  kind  or  anothor  become 
moro  dependable,  rraich  ma?;'  be  done.  Much  may  be  accomplished  by  putting  into 
execution  plans  that  I  have  advoca.ted,  talked  and  written  about  for  manj''  years. 


-  3  - 

These  plans  involve  the  widening  of  ri^t-of-ways.  How  wide  shoxdd  they  be? 
That  depends  upon  a  forecast  of  how  much  traffic  a  given  highway  will  carry  in 
the  future  years.  They  must  be  wide  enough  to  permit  of  widening  the  paving 
in  the  future.  They  should  be  wide  enough  to  provide  for  strips  of  land  along 
each  side  back  of  the  ditches  to  carry,  in  the  main,  native  plant  life.   In 
many  instances,  these  strips  are  already  planted  by  nature  with  trees,  shrubs 
and  other  plants  peculiar  to  the  areas  through  which  the  highway  passes.  Trom 
these  areas,  fallen  or  dead  trees  and  stumps  should  be  removed.  Some  thinning 
may  be  necessary,  not  too  much,  and  shrubs  and  herbaceous  perennial  plants  as 
well  as  trees  should  be  allowed  to  remain  in  place.  These  strips  need  not  be 
continuous.  Areas  that  are  now  bare  and  unplantod  may  be  allowed  to  remain 
so;  they  may  be  planted  or  they  maj'-  bo  protected  and  left  to  nature  to  plant. 
And  nature  will  do  just  that.  IThorcver  there  is  soil,  plants  of  some  kind 
grow  naturally  in  Florida.  If  any  piece  of  land  is  stripped  of  its  native 
vegetation,  and  the  surface  layer  of  soil  itself  carried  away,  in  almost  every 
case,  unless  it  is  hard,  steep  and  constantly  washed,  a  new  crop  of  plants 
will  cover  the  bare  surface  in  a  few  seasons.  Ho  piece  of  ground  is  so  poor, 
so  wot,  so  dry,  so  shaded,  so  swept  by  winds  of  the  sea  or  drenched  by  ocean 
spray  but  it  will  grow  native  plants  of  some  sort.  Tliese  should  be  given 
first  consideration.  They  may  not  be  the  most  beautiful,  they  may  oven  look 
straggly  and  unkempt,  but  no  plants  are  beneath  notice  and  most  of  them  improve 
in  appearance  and  increase  in  bcR'aty  as  they  grov   older.  The  widening  of  right- 
of-ways  should  be  sufficient,  wherever  advisable,  to  include  little  parks  or 
beauty  spots.  These  may  take  in  areas  near  lakes  or  rivers,  they  may  include 
groups  of  trees  or  spots  where  unus-oal  vegetation  grows.  Picnic  and  camping 
areas  should  be  provided  at  suitable  locations.  On.tlooks  to  beautiful  views 
in  the  distance  should  be  opened  up. 

When  bare  areas  are  planted,  care  and  knowledge  need  to  be  applied.  The 
materials  used  should  suit  the  plan,  they  should  fit  the  soil,  they  should  be 
adapted  to  the  particular  environment.  From  city  streets  we  have  borrowed  a- 
gain.  This  time  it  is  the  idea  that  trees  mast  be  planted  in  straight  rows, 
spaced  just  such  and  such  a  distance  apart.   It  is  high  time,  generally  speak- 
ing, that  the  street  plan  of  planting  be  discarded.   It  may  have  its  place 
here  and  there  but  straight  rows  of  trees  in  the  open  Florida  countrj'-,  backed 
by  the  miscellany  of  our  landscapes,  are,  on  the  whole,  not  desirable.  The 
better  plan  is  to  plant  the  trees  in  groups  at  suitable  locations,  three  or 
four  in  one  place  or  a  dozen  or  more  in  another.  ITo  greater  number  need  be 
used  to  the  mile  than  if  planted  in  rows.  The  effect  will  be  immeasurably 
better.  Needless  to  say,  the  materials  used,  preferably  native,  should  be  so 
selected  as  to  introduce  no  strange  or  discordant  note.  Along  the  back  of 
the  areas  so  planted,  a  fire  g'oard  v/ould  have  to  be  made  and  maintained. 

The  planting  of  low-growing  flowering  plants,  mostly  annuals,  adds  much 
to  the  beauty  of  our  roadsides.  There  are  splendid  examples  here  and  there 
throughout  the  state.  Phlox,  coreopsis,  gaillardia,  argemone,  verbena  and 
vinca  are  suitable.  Seeds  may  be  secured  from  plantings  already  in  existence 
or  small  quantities  may  be  purchased,  grown  for  their  seeds  and  these  sown  in 
due  season.  All  that  is  necessary  is  to  scatter  them  along  the  grass-covered 
roadsides.  Some,  not  all,  will  take  hold  and  their  numbers  will  increase 
from  year  to  year.  Late  October  or  early  November  is  about  the  right  time. 
It  will  be  noted  that  only  a  few  have  been  mentioned.  The  list  is  made  up  of 
sorts  that  are  self-perpetuating.  Once  started  on  suitable  soil,  they  come 
up  from  year  to  year  to  give  color  to  the  roadside. 


-  u- 


The  roadside  advertising  sign  nuisance  is  ever  in  evidence.  Unquestion- 
ably the  roadsides  in  the  broader  sense  belong  to  the  people,  they  are  for  all, 
and  not  for  the  advantage  of  the  few.  The  removal  of  all  advertising  signs 
from  our  roadsides  would  greatly  enhance  their  beauty.  If  anyone  with  an  open 
mind,  perhaps  there  are  few  such,  will  check  a  road  such  as  the  one  that  runs 
east  and  west  through  the  Ocala  National  Forest,  where  signs  are  absent,  a- 
gainst  one  cluttered  with  signs,  I  shall  not  say  where,  he  cannot  but  be  im- 
pressed with  the  quiet,  restful  beauty  of  the  one  and  the  discordant  note  in- 
troduced by  the  other.  How  can  this  nuisance  be  reduced  or  abated?  Wider 
right-of-ways  will  push  them  back,  suitable  legislation  will  help,  but  above 
all  an  awakened  consciousness  of  the  eternal  fitness  of  things  on  the  part  of 
the  public  is  necessary.  Here  and  there  communities  have  succeeded;  much  more 
can  be  done.  We  need  to  become  roadside-minded  and  plant-minded. 

In  Florida  there  are  many  beautiful  roadsides  and  to  a  few  of  these  atten- 
tion may  well  be  called.  Drive  the  Tamiami  Trail  from  Miami  to  Fort  Myers,  get 
out  on  it  by  sunrise  and  see  the  bird  life  of  that  region.  Take  to  the  road 
from  Starke  to  Green  Cove  Springs  in  April  and  reach  a  point  three  miles  west 
of  Green  Cove  Springs  by  3:00  A.  M.  ou  an  April  day  to  see  the  windf lowers  in 
bloom.  If  you  are  too  late  they  will  have  gone  to  sleep  for  the  day.  Follow 
the  Ocean  Shore  Boulevard  from  St.  Aurustine  to  Daytona  Beach  and  you  will  see 
one  of  the  most  unusual  plant  compositions  and  one  of  the  most  unusual  road- 
sides to  be  found  anywhere  in  the  world.  On  the  one  side,  the  vast  stretch  of 
the  Atlantic,  calm  and  smooth  or  disturbed  aid  wave-broken,  and  on  the  other 
a  sea  of  innumerable  palms,  trees  and  shrubs  smoot  ;d  and  flattened  down  by  the 
shearing  winds,  a  veritable  mosaic  of  colors  in  c.'.:,aea  of  brown,  gray  and  green. 
Farther  south  in  the  Jupiter  section  where  the  road  traverses  the  rolling  ocean 
dunes  of  long  ago,  much  the  same  appearance  is  presented.  Go  along  the  John 
Anderson  highway  and  see  the  wonderful  palm  groves  of  the  Halifax  country.  Take 
a  trip  over  the  road  from  Port  St.  Joe  to  Apalachicola.  Here  the  Gulf  of 
Mexico,  calm  and  placid  perchance,  comes  in  sight.  And  then  drive  up  along  the 
river.  Here,  too,  are  sand  ridges  and  palms.  Here  in  places  some  sjTTipathetic 
engineer  left  the  cabbage  palms  standing  on  the  roadsides  fairly  close  to  the 
paving  and  in  the  ditches  as  well.  Drive  from  Kissinmee  to  Haines  City  and 
note  the  giant,  centuries-old  cypresses  that  have  been  left  in  places  where 
trees  are  not  commonly  left.  They  are  splendid,  magnificent.  Would  that  we 
might  have  many  more  of  them  along  our  roads.  And  when  you  look  at  them  you 
cannot  help  realizing  how  pany  are  the  efforts  of  man  and  how  much  preservation 
means.   I  might  go  on,  but  time  is  up, 

I  have  spoken  in  the  interest  of  a  more  beautiful  state.  Will  not  all 
who  have  heard  me  help  in  bringing  this  about?
