PERENNIALS FOR DIFFERENT PURPOSES : Page 601
There are some perennials, among the most important of which arethe peony, of which the blooming period is very short and the foliageeffect during a great part of the summer may be consequently mo-notonous and uninteresting. In such plants it is highly desirableto have touches of colour throughout the later parts of the season.To accomplish this there can be introduced, among the peony plants,such types as the monkshood, the blazing star, lilies and gladioli, toprovide flowers and add interest to the otherwise monotonous mass ofgreen leaves.
A considerable part of the success of any perennial flower gardenis the presence of groups of perennials which present good bloomingcombinations. Often a garden is seen where some particular colournote attracts special attention. On close examination it is found thatthis effect is produced by a combination of colour brought about bythe successful grouping of two or more perennials. The averagegarden lover cannot become familiar, from his limited study of plants,with all of the interesting types of perennials which produce coloureffects that harmonize with each other. A list of these groupingshas been included in this chapter, and through further study manyothers may be found which will be equally effective.
