LOCUST.
The locust,[35] or black locust, is one of the desirable street trees in regions 6, 7, 8, and probably in region 5, as it thrives with comparatively little moisture. It makes a moderate-sized oval head that bears sweet-scented white flowers in late spring or early summer. Its greatest drawback is its liability to serious injury and disfigurement by the locust borer,[36] but with proper care this injury can be prevented.[37] In some parts of the East it is also subject to a leaf miner[38] that gives its foliage a burned appearance. In region 3 it holds its seed pods for several years and thus becomes very unsightly.

MAGNOLIA.
The evergreen magnolia[39] is one of the few good evergreen trees for street planting, but it is adapted only to regions 1, 2, 3, 11, 12, and 13. There are but few conditions that warrant the planting of a tree having foliage as thick as this, because of the dense shade, which is especially undesirable in winter. It grows to be a large oval-headed tree and bears beautiful large white blossoms in late spring or early summer.
