• Common name : Black Locust

Black locust is a medium-sized tree, growing up to 50 feet in height. The leaves are pinnately compound, and the oval-shaped leaflets are always paired. It has white blooms for only 10 days during spring, and black seedpods that are present on the tree throughout winter. The bark, seeds, and leaves of the black locust are all poisonous because it produces robin, an extremely potent phytotoxin. It is poisonous in both fresh and dried form, so people avoid tying horses to these trees or hitching posts made from its wood.
