The Black Locust has a upright, oval form often becoming irregular and picturesque with age. The dark blue-green leaves are pinnately compound with individual leaflets about 1 1/2" long. Has short, stubby thorns in pairs along the branches. Black Locust is quite attractive in late spring when the 6-8" pendulous clusters of fragrant white flowers open. The deeply fissured bark is dark grayish brown. Tends to sucker and seed freely so best used where a thicket is desirable. The Black Locust can tolerate very dry, infertile soils. Extremely adaptable to a wide range of growing conditions. Can reach a height of 30-60 feet and a width of 20-30 feet. The Black Locust is native to the Southern Appalachian Mountains. The Black Locust is a very fast-growing tree. Hardy to zone 3.
