Michel's tHlardy Perennial Plants 
know as Hardy Perennials have 
long been a source of delight in 
American gardens. In the past 
twenty years many of them have 
been improved in size, form, and 
color, but none of them have lost 
their sentimental charm. Because 
they are hardy and appear each 
year with renewed vigor, Perennials 
are naturally popular. 
| eee plants we have come to 
_ Without exaggerating in any way 
It may be said that practically all 
of the Hardy Perennials are of easy 
culture. By careful selection, it is 
possible to have a Perennial garden 
or a border which provides showy 
masses of color from early spring 
until frost. 
In planting Perennials, Jet us 
remember that well-prepared soil 
will more than repay the effort 
involved. Don’t try to crowd your 
Perennials. Allow them ample space 
in the beds or borders so that they 
can develop their natural form. The 
matter of grouping or arranging 
reflects the ideas of the individual 
garden maker. If possible, choose a 
location that has a background of 
flowering shrubs, evergreens, a 
hedge, or a wall. To be sure, 
Perennials cannot be expected to 
grow in dense shade, but there are 
some that flourish better in partial 
shade than they do in full sun. 
Others must have a sunny location 
in order to thrive. Tall-growing 
plants are most effective in the 
background; those in the middle 
ground would, of necessity, be of 
medium height with an occasional 
group taller than the rest for accent 
purposes. Then, those plants used 
at the edge of the bed or border 
would naturally be those of low, 
somewhat spreading growth. 
All too often, garden enthusiasts 
make the mistake of buying one 
plant of a kind with the expectation 
of getting spectacular masses of 
color. However, the result is usually 
spotty im its effect. Plant Peren- 
nials in groups of three or more, 
making an irregular mass. 
Seldom, if ever, can a Perennial 
border be planted perfectly the 
first time. There are always some 
plants that need to be shifted to 
more favorable locations. But this 
is all a part of the fun of gardening. 
Why not plant a new Perennial 
garden? There are many surprises 
In store for you.
