It often becomes necessary to make a selection of the lower-growing trees and shrubs to be planted in partially shaded situations. This condition may be brought about by the location of buildings, by the location of individual groups of large trees, and by the location of scattered specimen trees. We are not considering, in this compilation, the group of materials shown in Chapter XXVIII (Plants For Undergrowth Planting In Wooded Areas), which is not only adapted to this same condition of partial shade but has further value in being adapted to heavily shaded areas under wooded conditions. The shrubs in this list are those which may be used to a great degree of safety on lawn areas where a more or less refined planting is necessary, and where native plants are not so much desired.
The difficulty with many kinds of trees and shrubs planted in shaded locations is that the lack of sunlight prevents them from attaining a normal development. The foliage becomes thin and the branches are apt to grow long and spindly. Plants indigenous to such conditions, however, and which have come to thrive with this lessened supply of light, in partially shaded conditions, develop an interesting type of foliage; but flower effects on such plants are never quite as heavy as on plants which are supplied with sufficient light. In the making of plantations of this kind the only logical hope can be that of producing a foliage effect which serves as a background for a lawn and also often serves as a partial screen to give privacy to some garden or to shut off a service yard or other undesirable area.
The bush honeysuckle, the arrow-wood, and the privet form a denser foliage than any of the other types of plants in this group.
