331. Some of the Uses of Shrubs

The flowering and colored foliaged shrubs are used effectively on the borders of tree groups and in groups in the angles, curves, and corners of walks and roads, as shown in Figs. 83 and 84.

Large shrubs are often used to give irregularity to tree groups, as shown in Fig. 89.

In some cases where a view is not desirable a belt of shrubs may be planted on the inside edge of tree groups, and on many fine places well-kept shrubs are found along walks and drives. Downing's plan is often followed in well-kept places. He says: "Where the character of the scene is that of polished beauty the belts of shrubs may be arranged similar to herbaceous flowering plants, in arabesque beds along the walks. In this case shrubs alone, arranged in relation to their height, may occupy the beds; or, if preferred, shrubs and flowers may be intermingled."

In some cases herbaceous perennials are planted near the walk or road with low shrubs next, which are succeeded by taller shrub species reaching to a background of trees of small size.

Well-kept shrubs (152. Pruning and Shaping Shrubs) do not obstruct views like tree groups, and they can often be grouped so as to give an apparent reason for road and walk curves, and even to conceal a portion of the walk in advance.

At this time the purpose is only to give notes on the most desirable shrubs that succeed well over large areas of the United States.
