LAWN AND FLOWER GARDEN 113 



with geometrical beds of various sizes, so that plants of 

 different kinds may be put into beds of a size suitable 

 for their growth. 



If, however, we attempt to arrange our plants ac- 

 cording to size only, we may mix annuals and peren- 

 nials in such a manner as to cause much confusion, and 

 often a great irregularity in the appearance of the beds. 

 A plan for a flower garden requires a great deal of care- 

 ful study. 



Perennials. 



If we arrange all of the perennials in a central border 

 or long bed we may place the tall ones like hollyhocks, 

 larkspur, golden glow, boceonia, boltonia, helianthus, 

 etc., in a line in the middle. If the border is along the 

 boundary, the tall ones should be placed next the bound- 

 ary line, with those next in height in front and the smaller 

 kinds next the walk, so that the tops of all may be in 

 full view. The special treatment required by peren- 

 nials, in brief, is to give each kind an abundance of room 

 at planting and to divide frequently the roots of those 

 that tend to spread beyond their allotted space. Thus 

 peonies, iris, golden glow, phloxes, etc., spread so rap- 

 idly that the soil about them is soon exhausted, and 

 the plants and flowers make a small growth, when the 

 clump must be dug up and a small portion of it re- 

 planted in its place in soil made rich by adding stable 

 manure or by new soil carted in. Fig. 34 shows the 

 method of dividing perennial roots like the peony, etc. 

 The best time for replanting hardy herbaceous peren- 

 nials is in the early fall, but many of them will succeed 

 if replanted in the early spring. Lilies require an 

 especially rich, deep, yet well drained soil. In a wet 

 soil the bulbs grow small and near the surface, and in a
