NATIVE PLANTS SUITABLE FOR THE GARDENS OF 
MISSOURI AND ADJOINING STATES 
V. NATIVE PERENNIALS FOR THE HARDY BORDER 
With the exception of Cassia nictitans, which reseeds it- 
self every year, these plants are perfectly hardy and will 
do well in the border if given ordinary culture, particularly 
if some attention is given to obtaining as nearly as possible 
the natural conditions. Those marked (x) are not native, 
but have been introduced or escaped from cultivation and 
have established themselves so generally as to appear in- 
digenous in many places. 
Our native hardy perennials are not as well known, nor 
as extensively used, in our gardens as they should be, and 
it is hoped that this list will be the means of bringing them 
into more general use. Succession of bloom may be had 
from the earliest spring until the ground freezes, and many 
pleasing combinations of color and arrangements may be 
obtained by intelligent use of these plants.
