The strongest practical argument in favor of hardy perennials is the fact that, once planted, 
they continue year after year with no further gardening concern beyond cultivation, cutting, and 
thinning. In all descriptions, we aim to show normal matured height, blooming period, color and 
any special quality or utility; so that the reader may easily select and associate varieties to fit 
any desired purpose. 
Planting. Perennials may be planted as early in the spring as the 
ground is friable, or in autumn before ground is frozen. Large clumps 
are not necessary nor often desirable; the small divisions or pot-grown 
stock showing more thrift, vitality and development than the bulkier 
old roots. Any good soil enriched with fertilizer, dug deep and thor- 
oughly mixed, will be satisfactory. : 
Winter Protection. Everything listed in this section is ‘hardy’ but in 
varying degrees. A light covering of coarse straw, manure or leaves (not 
ever 2 or 3 inches deep) will give protection to all kinds, and insure 
safety.
