PREFACE 

THESE notes are for the beginner and 
the amateur. Their purpose is 

(1) To give a list of the most attractive 
and the easiest Alpine flowers. They do 
not include difficult or curious plants. These 
are for the specialist. 

(2) To guide him in the placing and culture 
of such plants. The notes are designedly 
short, and more elaborate lists and advice 
can be found in larger Alpine garden books. 

The compiler has had experience of most 
of these plants, and has cultivated them with 
(more or less) success, but the reader will 
remember that the directions which are 
appropriate to a dry and sandy position will 
not suit a low and damp one, and he must 
adjust his methods to his necessities. 

Here are a few rules which the amateur 
may follow with the qualifications which the 
aspect, the soil and the configuration of his 
garden make necessary : 

i. The best aspect is south-east.

2. The rock garden should be built of hard 

stone in tiers, and the rocks should 
slope slightly so that the rain may 
run away. If you must use sandstone, 
see that it is well weathered. 

3. Let your rocks be large, plentiful, 

well-placed and laid flat. Nothing is 
more odious than the ordinary 
" rockery " with a number of small, 
pointed and jagged stones. 

4. The soil should be mixed with grit 

and should be of good quality. Most 
alpines like a good garden soil, i.e., 
a light loam. If the soil is sandy it 
should be enriched by fibrous loam 
and leaf mould. If it is poor, give 
a little mild horse manure to the 
stronger plants. If it is heavy, it 
should be mixed with light soil and 
well-drained. Sphagnum moss is use- 
ful for plants which like damp. 

5. If the soil is wanting in lime, lime 

should be added where its use is 
indicated. Most alpines like lime, 
but some detest it. Old mortar- 
rubble is good. It is useful to have 
a lime area and a non-lime area, and 
to keep the lime-loving plants separate 
from the lime-haters. 



PREFACE 

6. Plant your alpines close to or at the 

foot of the rocks, for most plants like 
the shelter and the damp of a rock. 
Many plants should be wedged tightly 
between stones, e.g. the saxifrages. 

7. Top-dress your plants two or three 

times a year and see that small plants 
are kept firmly in the ground so that 
their roots are not exposed. Once a 
year top-dress with stone chips. 
Plants like this dressing, and it keeps 
the soil moist in summer. 

8. When planting spread out the roots 

well, giving them plenty of room, and 
press down firmly. In dry weather 
plunge the plant into water before 
setting it in its place. 

9. You should always have one or two 

moraines for some of the more delicate 
alpines, especially those with hair- 
like roots which only flourish in such 
soils, e.g., gentiana verna and the 
androsaces. 1 

1 The enthusiast who wishes to grow the high 
Alpine plants to perfection must make a small 
moraine, and he will do well to look to the natural 
conditions under which these plants live and which 
he hopes to imitate. A friend gives the following 
recipe : 

The moraines of the Alps are simply tumbled 
vii 



AN ALPINE ABC 



10. Plants of the same family should be 
kept together where this is possible. 
It is more interesting to have a saxi- 

masses of mountain dbris, stones of all sizes and 
shapes, sand and shingle, all knit firmly together, 
and containing the merest trace of primitive 
vegetable soil, washed down from the rocky 
heights. 

In our gardens the moraine must be made on 
the same plan. It should face as near as possible 
south-east, and be so arranged that its surface is 
well raised above ground level, the better to afford 
an easy view of its treasures. 

Let the main bulk be made up of stones varying 
from the size of a man's head to that of his fist. 
All the spaces between these stones are tightly 
packed in the building with the " moraine mixture," 
which is composed of fine quarry sittings, granite 
or limestone chips, or any other similar material 
which may be available. This is mixed with about 
one-fifth of its bulk of topspit peat and leaf-soil. 

The whole must be not less than 18 inches in 
depth, and should be bounded behind by rocky 
walls. The surface should show a few weathered 
stones half hidden in the general mass. 

A moraine built on the lines indicated here will 
retain moisture for very long periods and, in dry 
weather, may be watered with the rose. 

It is the larger stones which play the most 
important part in retaining water, and if these are 
of a porous nature, so much the better. Round 
these stones the roots of the plants will cling, always 
assured of those conditions which make life and 
growth easy fir them. 



PREFACE 

frage section, a primula section, a 
campanula section, than to have the 
various species of these plants scat- 
tered minutely about the garden. 

11. Aim at mass effects. The beauty of 

alpine flowers in their homes is largely 
derived from the lovely mass of colour 
which glows on the slopes and mea- 
dows. Thus make a carpet of gentiana 
verna or acaulis (200 or so if you can 
raise them). Among these plant the 
smaller anemones, androsaces, dian- 
thus alpinus and the small primulas. 
Above these, on a higher slope, plant 
masses of dryas, the larger anemones, 
and the blue aquilegias. 

12. You will have more success and a more 

effective display if you grow a moder- 
ate number of plants well than a 
large number of plants poorly. Only 
grow plants that thrive in your soil 
and climate. Do not worry about 
rare and difficult plants. Leave them 
to specialists. 

13. Plant flowering shrubs at the back of 

your rock garden, but do not overdo 
them. They should give a background, 
but should not dominate. The best 
are given in the following pages. 



AN ALPINE ABC 



14. Rock plants are delicate and short- 

lived things and must constantly be 
renewed. Never cease propagating 
either by division or cuttings or seeds. 
Collect your own seeds. They will 
often do better than bought seeds. 
It is generally better to sow such 
seeds as soon as they are ripe. 

15. Above all, remember that advice, rules 

and directions are useless without the 
seeing eye and the observing mind. 
Watch constantly and learn.

July, 1922. 



THE ALPINE HOUSE 

IF you have an uriheated greenhouse and 
can afford the space you will be able to 
grow many Alpine treasures under glass 
better than in the open. In their native 
mountains, protected from excessive rain 
by a blanket of snow, these little plants are 
warm and thriving and ready for the next 
spring. But under our bleak and moist sky, 
and exposed to our heavy rains, the andro- 
saces and such-like damp off or become 
miserable and ineffective mounds of flannel. 
In November, therefore, put some of your 
Alpines in your cold house, having carefully 
planted them in pots or pans in their proper 
soil, and in due time you will have a charming 
display of flowers, all healthy and untouched 
by dirt or damp. 1 

1 Plants intended for display in the Alpine house 
should be grown in shallow pots or pans. Two 
very useful sizes are 4 inches deep by 6 inches wide 
and 4^ inches deep by 6J inches wide. 

The soil must be carefully compounded to suit 



AN ALPINE ABC 



The following are specially suited to this 
treatment : 

All the androsaces. 

The smaller anemones, e.g. Appennina, 

Pulsatilla and Robinsoniana. 
Many campanulas, e.g., G. F. Wilson, 

garganica, pulla and pusilla. 
Cyananthus lobatus. 
Cyclamen Coum and Europaeum. 
Dianthus alpinus and neglectus. 
Gentiana acaulis and verna. 
Dryas lanata. 
Erodium corsicum. 
Fritillaria. 
Hepatica. 
Houstonia. 
Hypericum reptans. 
Iris reticulata. 
Linum arboreum. 
Lithospermum graminifolium. 

the requirements of each plant. It should not be 
finely sifted, and should contain plenty of coarse 
sand and stony material. 

The saxifrages, and, in fact, all the saxatile plants, 
are best grown and displayed by planting among 
comparatively large stones which are sunken deeply 
in the pans and form a miniature rock- work on the 
surface. Very pleasing effects may be obtained 
by the use of weathered pieces of stone arranged 
as a setting for the plant.
