In order that the citizens of St. Louis may be able to make 
the most intelligent use of native material, lists of the wild 
plants of the eastern United States suitable for various kinds 
of planting, will be printed in the BuLuErtin during the cur- 
rent year. There will be included lists on native plants for 
water gardens, native perennials for the hardy border, native 
hardy vines, native trees and shrubs with conspicuous flowers, 
fruit, colored bark, or autumn foliage, native trees for streets, 
and shrubs for streets, parks, and home grounds, native plants 
for poor soil and smoky, unfavorable city conditions, and na- 
tive conifers for gardens which are not in the smoky atmos- 
phere of large cities.

MISSOURI AND ADJOINING STATES 
I. NATIVE PLANTS FOR ROCK GARDENS 
A rock garden should, in a small way, be a duplication of 
a natural rocky bank or similar situation where considerable 
variation in soil and light conditions will permit the rowing 
of a large variety of plants. 
In this region the popular notion of confining a rock col- 
lection to alpine and other plants of high altitude must be 
abandoned, as these plants will not stand our changeable 
climatic conditions. Such plants are well adapted to many 
of the eastern and northern states, as well as some European 
countries, and the directions for rock gardens given in various 
books apply only to those sections. Fortunately the eastern 
United States is particularly rich in planting materials suit- 
able for rock-garden work, and if only native material or such 
exotic species as experience has proved of value be used, some 
very satisfactory results may be obtained. 
The purpose of this article is to discuss the native plants 
exclusively and to include only those which are of compact 
growth and neat habit, omitting any which spread rapidly 
underground and are likely to become obnoxious or difficult 
to eradicate. The plants listed are mostly hardy herbaceous 
perennials, and the few annuals and biennials are such as
