When peonies have completed their period of flowering there remains during the balance of the season a mass of green foliage which can often be made much more interesting by the addition of a few types of perennials which do not require any considerable space for their development, and which will lend touches of colour to this mass of green during the summer months.

Plate XXXIV. It is a source of much satisfaction to the plant designer to know that shrubs which are carefully selected for the colour of their flowers may produce very effective colour combinations. This plate shows the St. John's Wort (A), in combination with the sweet-scented buddleia (B).

Plate XXXV. The average person who has not become interested in the colour effects produced by the fruits of our common trees and shrubs can hardly appreciate the intense colour display of the American bittersweet (A), the Washington thorn (B) and the white fringe (C). For flowers: (D) bittersweet, (E) thorn and (F) fringe. (See page 162, group XX-B)

Plate XXXVI. The garden designer must always bear in mind that many of our shrubs which produce very uninteresting flowers are the ones which produce our most attractive fruiting effects. The variation in colours of the fruits ranges from the pure white of the snowberry (A), through the purple and porcelain blue of the beauty fruit (C), to the vivid reds of which the Japanese bush cranberry (B) is typical. For flowers: (D) beauty fruit, (E) snowberry, (F) Japanese bush cranberry. (See page 162, group XX-B)
