Michell 5 Hardy Perennial Plants 
Without exaggerating in any way it may be said that practically all 
of the Hardy Perennials are of easy culture. 
In planting Perennials, let 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. {f 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 occa- 
sonal 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, 
favorable locations.

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 in 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 
But this is all a part of the fun of gardening. 
Why not plant a new Perennial garden? There are many surprises in
