News of the Nursery

Visitors are welcome, and the latch-string is in easy reach. The
nursery is not primarily a show place, but flower lovers usually
find something of interest. Iris time in May, and Peony time
in June are worth the while of those living within driving distance.
New seedling varieties may be seen in both groups besides the
standard named varieties. Mid-summer and autumn also bring a
succession of flowering plants and shrubs. Native mountain flowers
and shrubs, growing successfully under garden conditions and fully
acclimated, will prove their value elsewhere under ordinarily favor-
able conditions. Visitors who bring lunches will find shade, cold
water at the spring, and fire-wood to boil the coffee pot.

The shipping season during April is not the best time to visit
the nursery, and please do not come expecting to have your order
dug for you while you wait; nor can we take time then to plan
your garden. Such interruptions delay our schedule of deliveries
which must be maintained for those whose orders are already on
file and who are entitled to prompt and efficient service .

At other times visitors will have the opportunity to order what
they like for delivery at a suitable season, but no solicitation will
be made. For the information of those living out of town, the
nursery is one mile mile south-east of the State University. Pro-
ceed along South Broadway to Twentieth Street, thence south about
six blocks to Bluebell Avenue, then three blocks east to Twenty-
third Street.

Many of my friends know that the nursery is much more than
a mere commercial establishment. Besides fishing, which is my
favorite sport and recreation, I find the procession of the growing
season a continual joy. There are many attentions that I cannot
content myself to let other hands perform, any more than I would
let some one pull my trout out of the stream. But fortune has given
me good helpers, and the work goes on easier than formerly, and my
plans and dreams materialize with greater certainty.

It would take too long to tell of all the experiments with new
plants, learning their likes and pet antipathies; the breeding of new
varieties, seeing certain characters, when united by crossing, sub-
merge and then reappear in subsequent generations, forming com-
binations heretofore unknown. Then there are individual differences
among the wild plants, foreshadowing improvement through selection.
Many such are on trial.

It is not a matter of “Mind in the Making,” nor a question
of “Why We Behave like Human Beings.” Just a few of the tangible
things in the making, which are destined to influence more or less
our behavior.

Terms and General Information

Herewith is the General Catalogue of Rockmont Nursery for
the season of 1927. It includes both plants and seeds of rare
flowers and shrubs listed formerly as “New or Noteworthy Plants.”
It is expected that all the material can be furnished, either spring
or fall, without change in price, except such changes as shall be
indicated in the

Fall Catalogue. This will be issued about September, and will
include my approved list of Peonies, economically priced, and my
own introductions. Also, a list of dependable Lilies, and other
stock for fall planting. In addition to the present list of Mountain
Flowers for July and August delivery, there will be featured other
choice alpines and rare offerings for autumn only, valuable ma-
terial for the rock garden w’hich should not be overlooked.

Very Important. In making up your order this spring, please
do not include items from the fall catalogue, nor from any old
catalogue. The catalogues are all plainly dated so you need make
no mistake. By observing this rule you will save probable delay
and obtain much better service.

Special Items. Because I list so many unusual plants, there
come to my desk inquiries, from advanced collectors who want other
rare species to complete their collections, or requiring information,
or plants for experimental or other uses. I would gladly comply
with these requests, but my facilities and time do not permit. The
special collection of plants not listed in the catalogue is practical
only when a large quantity of one kind is required.

Canadian and Foreign correspondents who receive this catalogue
are requested to limit their orders to seeds, remitting cash in full
with order. Retail orders for plants, with the required attention
to permits and declarations, cannot be accepted for delivery during
the spring shipping season. It is suggested that arrangement be
made for autumn delivery, allowing ample time to insure compliance
with all requirements.

Time of Delivery. Seeds can be furnished at any time during
the entire season. The spring shipping season for plants opens in
March, subject to weather conditions, and continues through the
month of April, ending May 1st to May 15th, evergreens comprising
the bulk of late shipments. Lilacs and other plants which start
growth early should be ordered early enough to permit delivery
before April 15th.

I aim to time deliveries to suit the convenience of purchasers,
but the inevitable rush season can be partly overcome if patrons
will order early and accept delivery when most practicable. When
delivery is required at a particular date it should be clearly stated
in your order.

Size of order — Forwarding. As a measure of business economy
and to promote efficient service, I do not solicit, and reserve the
right to decline orders for seeds of less amount than $1.00, and
plant orders less than $2.00. Trial orders should be large enough
to permit a fair showing of my stock and service.

Seeds are delivered anywhere postpaid. All other stock is
delivered at purchaser’s expense. Shrubs and other heavy stock
should be sent by express. Because of light but efficient packing
the cost of transportation should seldom exheed 15% of the value
of shipment, and often will be less. Herbaceous plants and small
shrubs can be sent by parcel post at an additional cost to be added
to the value of the order as follows:

To points west of the Mississippi, add 5%.

To points east of the Mississippi, add 10%.

Errors. Report errors or other claims promptly. Promptness
will assist in making corrections that will be satisfactory. Always
keep a, copy of your order for comparison.

Guaranty. Extreme care in the packing of stock insures safe
delivery in the ordinary course of express and Parcel Post, and at
the same time reduces unnecessary weight to the minimum. Much
commendation is expressed upon the excellent condition of stock
upon arrival and the low transportation cost, due to light packing.
Any loss or damage in transit should be reported promptly for
investigation and adjustment, stating full particulars. Losses or
delays due to the operation of quarantine or inspection laws of
receiving states must be borne by the purchaser.

Names and Addresses. When writing, if you will include the
address of anyone interested in the line of plants or seeds I have to
sell, I shall gladly mail a catalogue. Your good-will so expressed
will be sincerely appreciated.

Address all communications to D. M. Andrews, P. O. Box 493,
Boulder, Colorado.

Evergreens

The native evergreens of Colorado are unsurpassed as to hardi-
ness, and at the same time possess unequaled beauty of foliage
and outline. An investment in good evergreens will pay large
dividends every month of every year. Fine specimens are the result
of years of care and watchful waiting. Cultivation, watering, stak-
ing, tying, pruning and the use of valuable land are some of the
items that enter into the cost of production.

My specimen nursery-grown evergreens are several times
transplanted, insuring an ample root system, and are dug with a
solid ball of earth which encloses and protects the roots. Collected
wild evergreens have poorly furnished tops and inferior roots.
Although offered at somewhat lower prices, it is real economy to
plant a smaller nursery-grown specimen. Because in a short time
it will surpass the collected tree both in size and beauty, and with
a much smaller percentage of loss in planting.

Prices are for first grade trees of good form, dug with ball
hnd burlapped. The 12-inch and 18-inch size include boxing for

shipment on orders amounting to $15.00 and over. Larger sizes are
F. O. B. at the nursery. If boxing is required the cost is additional,
and amounts usually to 25% if two or more trees are shipped

together. I do not recommend shipping large sizes farther than local
distances, because balled trees are very heavy.

Trees selected at the nursery will be charged for according to
value, which will range from 20% below to 20% above printed prices.
A specimen of broad form will be charged one size larger than
actual measurement.

Culture. For Colorado conditions, set an inch or two deeper
than the former level and leave a slight depression to aid in water-
ing. Fill and tamp the soil firmly after slitting the burlap and

turning it down from the top of the ball. Water regularly once a
week during hot weather, and occasionally through the fall, enough
each time to wet thoroughly to the depth of the roots.

Native Colorado evergreens are indicated thus (*).

Juniperus pfitzeriana. Pfitzer’s Juniper. A low, broad everygreen
of plumose habit with blue-green healthy foliage. Spread, 12

inches, $2.00.

Juniperus sabina. Savin Juniper. A low spreading, many
branched evergreen with dark green foliage. The half-ascending
poise of the branches, dwarf habit and the ease of culture all com-
bine exceptional value with no faults. Spread, 12 inches, $2.00;
18 in inches, $3.00; larger at $2.00 per foot.

Juniperus scopulorum. Colorado Silver Juniper. (*) Of formal,
compact upright habit, it is particularly pleasing for the feathery
texture and silvery-blue luster of its foliage. Its color and fresh-
ness is retained well through the winter and the tree holds its
lower branches and symmetrical form longer than other types.
This is the superior type found only in the higher foothills of
northern Colorado. Height, 12 inches, $1.50; 18 inches, $2.00;
24 inches, $3.00; 30 inches, $4.00; 36 inches, $5.00; 42 inches, $6.00;

most universally successful of the spruces. Green and slightly blue
form, 12 inches, $1.25; 18 inches, $1.75; 24 inches, $2.50; 30 inches,
$3.50; 36 inches, $4.50.

4 D, M, ANDREWS, BOULDER, COLORADO

Picea pungena glauca. Colorado Blue Spruce. (*) My selected
blue specimens are often equal in color to the Koster variety and
are more symmetrical than when grafted. The blue color does
not reappear at its best after transplanting till the trees are fully
established. Twelve inches tall, $2.50; 18 inches, $3.50; 24 inches,
$4.50; 30 inches, $6.00; 36 inches, $7.50; 42 inches, $10.00; 48
inches, $12.50.

Picea canadensis. Black Hills Spruce. One of the hardiest of all
spruces, symmetrical, compact, dark green. Easily grown and
fine for contrast. 24 inches, $3.00; 30 inches, $4.00.

Deciduous Shrubs and Trees

To avoid too many headings there is no separate list of novel-
ties. It does not appear necessary to print a description of com-
mon shrubs for the reason that numerous descriptive catalogues are
available. This catalogue is unique in offering many choice shrubs
and plants not elsewhere obtainable, and these are briefly described.

“Every year plant something new” is a practical slogan. It will
make the garden outstanding and noteworthy, besides being a con-
stant source of interest and inspiration. All the following shrubs
are hardy and succeed under ordinary treatment unless special culture
is indicated.

Items formerly catalogued in “New and Noteworthy Plants” are
followed by an asterisk in parenthesis (*); numerals in same paren-
thesis indicate height in feet; X means unmailable; small shrubs can
be mailed anywhere in the U. S. at a small additional cost (see In-
formation and Terms).

Hedge plants. The best shrub for a trimmed formal hedge in the
mountain region is the European Privet, Ligustrum vulgare. My
Rockmont strain is all propagated from stock originally imported
from Sweden and is extremely hardy and branches freely, making
a dense hedge. I offer this in three grades, as follows: 2-3 feet,
bushy, $20.00 per hundred; l%-2 feet, bushy, $17.50 per hundred;
Lighter stock, $12.50 per hundred. Berberis Thunbergi, Forestiera
neomexicana, Lonicera tatarica and Spiraeas are recommended for
hedge purposes. Forestiera and Lonicera may be trimmed like
Privet; other shrubs should be clipped only enough to keep the
row fairly uniform.

Holodiscus microphyllus, Mountain Spray (*4) 1.00 9.00

French Hybrid Lilacs

We are indebted to French specialists for a wonderful trans-
formation, in the Common Lilac, now showing both single and
double flowers; larger size of both flower and truss; a great range
of color; best of all, a later blooming period insuring a full display
of delightfully fragrant flowers nearly every season. Their growth
is vigorous, they are absolutely hardy, they thrive almost anywhere.
If you have overlooked these wonderful French creations you have
missed the best garden investment you can possibly make.

The imported plants formerly sold were grafted, and often the
inferior stock sprouted and choked out the true variety. I have propa-
gated the following varieties on their own roots and they will always
remain true to type and should thrive for a quarter century. Several
choice and rare varieties are here included. If you are looking
for something extra choice in a flowering shrub there is nothing
more permanent. Years of pleasure will many times repay the
first cost. All are double except as noted.

The size of bushes averages 18 to 24 inches in height. Of a
few kinds only, prices are quoted for large bushes which will
average four feet tall in heavy stock; the supply is rather limited
and can be furnished only in the kinds quoted. Own-root lilacs
are scarce, propagation is slow and prices probably will increase.
Orders for lilacs will be filled in rotation and money returned for
kinds sold out. I do not substitute without permission.

vidual flowers, midseason to late, rated as the best late white, fine
stock. $2.50 each.

Vines and Trailing Plants

The following vines are offered in the alphabetical list of Shrubs
and Trees, except Clematis Simsii, C. Texensis and Vinca minor,
which are herbaceous perennials. Clematis Texensis (Syn. Clematis
coccinea) is easily grown and hardy, a rapid grower, begins to
flower in June and blooms constantly till frost. The splendid scarlet
flower-bells are later followed by the golden plumose seed heads, and
scarcely any plant in the nursery has attracted so much attention.
An addition to our stock makes possible a lower price for strong
roots, namely, 75 cents each, three for $2.00.

Ampelopsis Saint Paulii is a little more slender and a more
tenacious climber than A. Engelmanii; however, my stock of the
latter has been propagated from the originator’s stock, obtained
more than thirty years ago, and is superior to much of the stock
offered under that name.

Euonymus radicans vegatus and Hedera helix gracilis are ex-
tremely valuable evergreen climbers, best for north or east ex-
posures, as the winter sun burns their foliage in this climate. They
are otherwise hardy and may be used as a ground cover over banks
or among rocks.

New or Noteworthy Flowers

and General List of Perennials

Hardy flowers afford a long season of growth and bloom, a
wealth of material for cutting and lessen the labor of gardening.
They respond favorably to good care, yet because they show such
ability to thrive without much care they are too often neglected.
Excessive fertility and moisture should be avoided, as it will result
in a rank growth with diminished flowering. Thorough and frequent
cultivation, to destroy weeds and conserve moisture is the surest
bid for success.

One of the greatest mistakes of gardening is to depend for
effect upon a single plant; a group of three or five is the smallest
display that can be advised, even for a small garden.

Native plants of Colorado and other western states are indi-,
cated by an asterisk (*). Numerals in the same parenthesis indicate
ultimate height in feet. Culture of native plants is discussed under
“Seeds,” and in the last fall catalogue, a copy of which will be
sent upon request. Please read “Information and Terms” before
making up your order. Other native plants for rock gardening are
named in the July and August section, and an additional list will

appear in the fall catalogue, ready in September.

stock. The prices of last fall can be taken as an approximate
basis for next fall; the changes, if any, will be merely an adjust-
ment to market conditions. No peonies will be sent out in the

Iris Introductions

It is of course too soon to have reports from my iris introdu-
tions, except Odaroloc, which has won unqualified approval. My
prediction is that Alabaster, Amerind and Candlelight will even
surpass it in popularity, because they have no near competitors.

My sale-stock of Amerind was entirely sold out last fall and I
have no more to offer before July. Of Alabaster and Candlelight I

still have a small reserve to offer this spring. There will be no
reduction in price during the present year, except that after July
first, an order for the set of three at $30.00 will have included, free
of charge, one rhizome of Odaroloc. The stock is necessarily limited,
and orders will be filled strictly in rotation. A payment of $10.00
will secure your reservation for the set, delivery at your convenience
after early July.

Alabaster. (Andrews 192G) Pure white flower, medium to large,
of exceptionally fine form; well arched broad standards slightly
ruffled, meeting at the tips. Falls broadly flaring, rather wide
with slightly ruffled tips. Beard nearly white, shading to yellow
within, styles white. The purity of its whiteness, the absence
of veining and the beautiful lasting texture of the flower will
doubtless set a new standard in white Iris. Of vigorous habit and
increases with fair rapidity. Price $10.00 per strong single rhizome
for immediate delivery.

Amerind. (Andrews 1926) Metallic bronze in nearly a self

color, the standards slightly more golden than the falls. Stems
low-branched, nearly four feet tall, carrying ten to twelve flowers
of large size and excellent substance. A plant and flower which
attracts from a distance, and which bears inspection. Exceedingly
vigorous, with ample foliage, increases well and has a long blooming
season from midseason to very late. Price $10.00 each, delivery after
July 1st.

Candlelight. (Andrews 1926) A Caterina x Aurea cross, with
large flowers of pale pinkish lavender strongly illuminated from

within with a rich golden glow, at once difficult to describe but
very lovely. The glow extends nearly to the tips of standards and
falls, which afford just enough contrast to give a lively yet soft
color effect. The name Candlelight is realistically descriptive. The
plant is tall, nearly four feet, and a vigorous grower. Price $10.00
each.

Odaroloc. (Andrews 1924) Seedling of a tall white plicata,

fertilized from another white seedling. Although resembling a pallida,
it has directly no pallida nor Caterina inheritance. Height 46 inches,
pure self color, light mauve to lobelia-violet. Both standards and
falls measure 2y2 inches wide and 3 y2 inches long. The 8 or 9

enormous flowers are borne on very strong erect stems well above
the 30-inch glaucus foliage. The lower branches are rather long,
carrying the flowers high without crowding. The flower is well
arched, symmetrical, with flaring falls, good heavy substance, orange
beard. Growth exceptionally vigorous, forming well balanced clumps
and a good multiplier. Strong single roots. $5.00 each, 3 for $12.50,
$50.00 per dozen.

Ophir Gold. (Andrews 1925) Golden yellow flowers of pure
color without veining, borne on 33-inch stems. Compared with Sher-
win Wright, the flower is larger and ten days later. Departing in
habit from the usual stiff and contracted inflorescence of the Varie-
gata group, this excells in graceful carriage and is a most profuse
bloomer, with flowers of exceptionally good substance. It increases
freely, and having a fairly large stock, I offer good single roots at
$2.00 each, $20.00 per dozen.

Tansy. (Andrews 1025) For local use I recommend this as
superior to Sherwin Wright, being of clearer color, taller and of
better substance. I have a fairly large stock and offer at a con-
servative price. Perhaps it is worth the dollar to try what I believe

to be the best early yellow. Single roots $1.00 each, 12 for $10.00.
$75.00 per hundred.

Colorado Mountain Flowers

for July or August Delivery

Some delightful spring flowers are dormant for such a little
while after the snow is gone that the shipping season is brief, or
better deferred until the dormant period soon after blooming.

When sending your spring order, it is suggested that you include
an order also for these, on a separate sheet, for July or August
delivery. If your vacation occurs during these months, it can be
arranged for the plants to reach you upon the date of your return.
Order now and pay at the time of delivery if more convenient.

The prices of this summer sale have been reduced on most
items, for the sale period, and no longer. One object of this is to
divert business from the rush seasons of spring and fall. The
resulting benefit to the customer, besides the price saving, is the
opportunity to plant at Nature’s approved time, permitting ample
development of new roots before cold weather. A large, cool cellar
and excellent packing facilities insure safe handling and delivery.
Orders received after September 1st will be charged at the prices of
the fall catalogue.

Note carefully the excellent offerings, ideal material for the
rock garden, and make certain of the special prices by sending your
order now.

Seeds of New or Noteworthy Plants

It is well known that mature plants of some species do not
transplant easily, and there are other reasons why seeds are the
logical medium of distribution for certain of our western flowers.

The list of a year ago, without descriptions, exceeded in volume
of sales my expectations, but some very good items were overlooked
because unfamiliar and undescribed. The descriptive list which
follows contains about thirty more items than appeared a year ago.
Some of these are charming new flowers, never before offered, and
others have not been listed for several seasons. More than a super-
ficial glance over the list will assure every reader of the excep-
tional opportunity to enrich any garden at small outlay.

Planting suggestions. Almost without exception the Colorado
Mountain flowers grow naturally in a granitic or peaty soil having
distinctly an acid reaction. While some plants of this group are
quite indifferent to lime, others are most decided in their prefer-
ences, and therefore the rectification of calcareous soil is advised.
Two methods are suggested. One is to incorporate with the soil,
if of suitable texture, liberal amounts of peat or leafmold, especially
the top soil from oak woods, rich in natural tanic acid. The other
is to apply with a sprinkling can commercial tanic acid in a dilute
form, about two ounces to a gallon of water, repeating once or twice
during the growing season. A gallon should cover several square
yards, after which sprinkle with clear water to wash off the foliage.
For a seed bed the mechanical condition of the soil is important.
I plant in open beds, and prefer a soil mixture prepared as follows: —
one part mellow garden loam, avoiding clay, one part sand and one
part or less of humus. A fine sandy texture facilitates drainage,
prevents crusting, retains moisture and tends to develop fiberous
roots. This paragraph applies to soil preparation for mountain plants
as well as for seeds.

The time for sowing seeds may depend upon local conditions
or may be perhaps a matter of personal preference or convenience.
Very early spring has its advocates, but in this climate late frosts
often damage the tender growth, so it has become my practice to
sow during the early summer which has resulted in better stands
and avoids the first crop of weeds which may be destroyed before
planting the seeds. I make the beds four feet wide, over which
are supported lath shades 15 inches above the bed. They are watered
from a fine overhead spray. I use a planting board which indents
the rows, three at one time, six inches apart. The mark is very
shallow for fine seeds and they are covered very thinly with fine
sifted sand. Temperatures must not reach a high degree, and in
our dry climate this is easily regulated by sprinkling, which cools
quickly by evaporation. In a humid or very hot climate seeds may
be planted earlier or later to avoid the extreme heat of midsummer.

It frequently happens that some kinds do not germinate for sev-
eral months after planting, but the same care, irrigation and careful
weeding is exactly the right treatment for the slow ones. Large
seeds should be covered deeper; I use the fine sand in all cases.

24

D. M, ANDREWS, BOULDER, COLORADO

but a different planting board to mark the furrows deeper. I am
a firm believer in shallow planting with careful attention to watering,
and I am sure that much failure results from too deep planting or
from the crust that forms when covered with heavy soil.

Most shrub seeds and a few perennials known to germinate slowly,
I plant late in the fall and mulch with sphagnum or excelsior. The
use of coldframes or a greenhouse may sufficiently advance many
seedling perennials to induce flowering the first season.

Seed Orders may be sent at any time, spring, summer or fall.
Late in the season a few substitute items should be included. You
can assist me in filling your order promptly by writing your seed
order with full address on a separate sheet from your letter or
plant order; also by ordering before the shipping season for plants,
which begins about March 15th.

No Seed Order less than $1.00. Except a few items individually
priced at 50 cents, all the following named seeds are sold at the
rate of five packets for $1.00; additional packets 20 cents each. An
order may include any two 50-cent packets, or one 50-cent packet
and three or more packets at 20 cents. It will be noted that “trade
packets” of certain varieties are offered at 50 cents; these trade
packets contain at least three times the amount of a small packet.
Seeds are delivered anywhere postpaid. All are perennial except as
otherwise indicated.
