Robinia hispida

Overview

Bristly locust (Robinia hispida) is a deciduous shrub or small tree that is native to the eastern United States. It typically grows 6 to 12 feet in height with an upright, rounded crown. It has dark green, alternate, pinnately compound leaves with 3-9 leaflets, each with a prominent bristle tip. Showy white to pinkish fragrant flowers appear in late spring, followed by dark purple pods. The densely twigged branches are covered with hooked bristles that give it the common name of "bristly locust". It tolerates wide ranging soil types and is drought tolerant once established. It is an excellent choice for home landscapes or as a wildlife plant and it is most often used as an ornamental or screen plant.
