Gleditsia triacanthos

Leguminosae (Fabaceae)

Honey locusts as the species type are seldom used in the landscape because of their vicious three- pronged thorns, which can sometimes be as long as 12 inches. They grow on rich soils in the eastern third of the state, although they can tolerate drought and a wide range of soil conditions. Honey locust is a medium to large shade tree with vase-shaped, stratified branching, yellow fall color and soft-textured summer foliage that provides light filtered shade. There is a thornless variety (Gleditsia triacanthos var. inermis) that can be used for landscaping.
