Honey Locust, an ornamental tree of eastern North America. It is known also as the sweet locust and, in Great Britain, as the three-thorned acacia. A species of mesquite is also called honey locust.
The honey locust grows up to 140 feet (43 m) high. Trunk and branches bear spines three to four inches (8 to 10 cm) long. Each of the featherlike leaves is made up of 20 to 30 leaflets. Greenish flowers appear in clusters in early summer. The fruits are flat, twisted pods 8 to 18 inches (20 to 45 cm) long, containing sweet pulp and numerous oval seeds. These pods are an important source of food for rabbits, squirrels, and other wildlife. The tree's hard, coarsegrained wood is used for fence posts and railway ties.
The common honey locust is Gleditsia triacanthos of the pea family, Leguminosae.
