Michell’s Hardy Perennial Plants 
These old-fashioned hardy flowers are the garden favorites, and justly 
so, for there is no time during the entire flowering season when some 
variety is not in bloom. They are particularly valuable in late summer 
and autumn when there are few shrubs in bloom. Beginning in early 
April they provide a constantly varying pageant of color throughout the 
summer and until stopped by severe frosts. They appear regularly, year 
after year, and as each variety has a fixed time for blooming, careful 
selection will insure flowers for cutting from early spring to late fall. 
The Hardy Perennials are most satisfactory when planted in a border, 
in front of a hedge, fence, or wall, or in the open garden. When planting, 
the soil should be dug to a depth of 134 to 2 feet, pulverizing it thoroughly 
and working in a liberal amount of well-rotted stable manure or other 
fertilizer. Place in groups of three or more plants of one variety, the 
taller-growing ones at the back, the medium-high ones in the center, and 
the dwarf varieties at the front. It is important, too, that the plants are 
so placed that there will be some flowers in all parts of the border at all 
times. This can easily be accomplished by consulting our descriptions 
for time of flowering. Our book, “The Hardy Flower Garden,” is an 
instructive publication which can be had free on request. We offer only 
such varieties as can be planted in autumn.
