Robinia pseudoacacia: Black Locust: ENH-728/ST570, 2/2014

Abstract

A fast-growing native deciduous tree, Black Locust is capable of reaching 70 to 80 feet in height but is more often seen 30 to 50 feet tall with a spread of 20 to 35 feet. The upright growth and short, irregular branches form an open canopy and cast light shade below the tree, allowing a lawn to thrive. The 6 to 14-inch-long, dull, blue/green leaves, made up of multiple leaflets, are some of the last to appear in spring and often drop early in the autumn, just barely fading to a sickly yellow/green before dropping.
