New or Noteworthy Plants 
Including Colorado Wild Flowers of Mountain and Plain, and other 
Perennials for the Border and Rock Garden. 
Under this section will be found a wealth of choice plants for the 
average American garden; the best of old and new offerings, and many- 
exclusive items not obtainable elsewhere. 
The Dry, Sunny Rock Garden. Rock gardening under diverse 
American conditions is taking on several distinct phases. An important 
development is the dry, sunny rock, or desert garden. Heretofore 
suitable plant material was hardly to be found. Our experimental 
facilities have made available from this region, many attractive items 
of proven value in this field of novelty and charm. 
Start with a small area, preferably on a sunny slope, and provide 
drainage until it hurts. Be prepared to sprinkle during active growth 
and in prolonged drought. Then when rains occur during dormancy 
the provisions for drainage will prevent harm from excess moisture. 
Dry treatment for these children of the desert, together with a rather 
lean, friable soil has the tendency to check rank growth and floppiness, 
and encourages freedom of bloom. 
It is your privilege to enjoy novel garden effects, with inexpensive 
preparation and a moderate outlay for plant material; but a good friend 
of mine gives sound advice. He says, “Do not try to raise goldfish in 
a bird cage, nor canary birds in a lily pool.” 
Planting List. The following plants are recommended: Hardy Cacti, 
all kinds; Artemisia, sp. listed; Callirhoe. Delphinium Geyeri; Hardy 
grass, Orizopsis; Leucocrinum; Lesquerella; Lewisia rediviva; Liatris 
punctata; Malvastrum; Mirabilis; Oenothera brachycarpa. Pentstemon, 
most Colorado sp.; Phlox andicola, bryoides, Hoodii; Tanacetum 
capitatum; Townsendia; Yucca, all western species. 
Native Plants of Colorado and other western species are indicated 
by the asterisk (*); Rock garden plants thus (J), and Alpines by (@). 
The soil for Colorado plants in general should be of mellow texture, 
well supplied with humus, not very rich. The natural habitat for nearly 
all mountain flowers varies from nearly neutral to acid; an excessive 
lime content should be avoided.
