Robinia pseudoacacia 'Purple Robe': 'Purple Robe' Black Locust: ENH-730/ST572, 2/2014

Abstract

This cultivar of Black Locust probably grows to about 40 feet tall with a spread of 20 to 35 feet. The upright, rounded growth and short, irregular branches form a tighter canopy than the species and cast medium shade below the tree, allowing a lawn to grow. 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. Original publication date November 1993.
