Here in its native range, black locust is better known for persisting than thriving. Its leaves and young stems are prone to insect attack, weakening and deforming trees that often die back and regrow as root sprouts. Consequently, black locust is not considered particularly attractive here, so this species is seldom planted by landscapers. Outside its native range and free of its pest problems, particularly across much of Europe and Asia, black locust thrives and is prized for its durable timber and its ability to enrich soils.
