PERENNIALS FOR DIFFERENT PURPOSES 221 



fine thing like the evergreen candytuft. In the edge of the shrubbery 

 bed can always be found room for some bulbs; they really seem to 

 prefer the slight protection of the overhanging branches and the soil 

 around the roots of the other plants. An additional consideration is 

 that the flowering season of bulbs is not encroached upon by the foliage 

 of the shrubs, as would occur to the detriment of perennials that 

 flower later in the year. Formal regularity in planting should be 

 avoided because most perennials and bulbs appear best in small masses 

 or clumps. 



In designing a border planting of perennials or annuals located at the 

 edge of masses of shrubs an ample width of four or five feet should be 

 allowed, especially if this is the only place for the development of a 

 flower border. Unless this provision is made and frequent pruning 

 of the shrubs resorted to, the branches of the shrubs even then are apt 

 to encroach upon the smaller plants at the front. This does not, 

 however, apply to bulbs. Where it is necessary to develop a flower 

 border in combination with a border of shrubs which shall serve as its 

 background, little success will follow the attempt to develop such a 

 border, especially in relation to tall-growing shrubs, if the flower 

 border is placed upon the north side. If the shrub border or hedge 

 is to consist of tall and vigorous-growing shrubs or columnar trees to 

 provide a screen against objectionable views, the designer must always 

 remember that competition of perennials with the greedy root systems 

 of such plants will starve the perennials.

A. Types of Hardy Perennials for General Use. For the 

 average person who is developing a small garden a knowledge of some 

 of the standard types of hardy perennials, which are well adapted for 

 general use, will often meet the requirements. This group contains 

 standard types of perennials which are adapted for general use, and 

 which with ordinary cultivation will produce interesting flower eff'ects.
