Honeylocust (Gleditsia triacanthos f. inermis 'Skycole' Skyline®) is a tough, medium-sized flowering tree that casts a light shade that won't kill lawn grasses. It typically grows 60–80 feet tall with a rounded spreading crown. Inconspicuous, greenish yellow to greenish white flowers appear in racemes in late spring. Flowers are followed by long, twisted, and flattened, dark purplish-brown seedpods (to 18 inches long) that mature in late summer and persist well into winter. Seedpods contain, in addition to seeds, a sweet gummy substance that gives honey locust its common name. Skyline® is a thornless variety with a stronger upright growth form, few seed pods, and excellent yellow fall color. This is an adaptable tree especially good for streets and parking lots.
