The honey locust is a fast-growing tree, used in areas that are difficult for anything else to grow, ie: parking lots, sidewalk tree squares. Flowers appear in late spring, are greenish-yellow, and provide nectar for bees, butterflies, and moths. The varietal "inermis" is thornless. In summer, the tree provides dappled shade, leaves turn yellow in fall. Drought tolerant.
A 6-8 inch seed pod is produced and is eaten by herbivores, the pods contain a sweet gummy substance that gives the tree its name.
