The honey locust, also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys.
Gleditsia triacanthos, commonly called honey locust, is native from Pennsylvania to Iowa south to Georgia and Texas. It typically grows 60-80’ (less frequently to 120’) tall with a rounded spreading crown. Trunk and branches have stout thorns (to 3” long) that are solitary or three-branched. 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” long) which 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. Species plants are generally not sold in commerce today because the thorns and seedpods are considered to be significant liabilities.
