MichelPs Hardy 
Perennial Plants 
All of the old-fashioned flowers which were the delight of our 
grandmothers are to be found in this class of plants. They are all 
perfectly hardy and die down in the fall, appearing again in the spring 
with renewed vigor. 
There is an ever-increasing demand for Hardy Perennial Plants, 
as they are of easy culture and there is not a time during the whole 
season when some are not in bloom. Each variety has a fixed time 
for flowering, so that by making a judicious selection a succession of 
blooms may be had from early spring until the late autumn. There is 
no set rule for the planting of Perennials. The amount of room at 
one’s disposal, the location, and also the individual taste of the planter 
must be taken into consideration. Probably the most satisfactory 
results are obtained from a hardy border backed by a hedge or a 
fence, planting some of the taller-growing sorts such as Hollyhocks, 
Hardy Asters, Bocconias, Helianthus, and Boltonias in the back, 
graduating the shorter-growing sorts toward the front and finishing 
the border with an edging of Plumbago Larpentse, Phlox subulata, 
Arabis, and other of the dwarf growers. 
Our booklet, “The Hardy Flower Garden,” is an instructive pub¬ 
lication and will be sent free on request.
