  • Description

  • Notes

This vigorous tree grows 40 to 50 feet tall and 20 to 30 feet wide, and provides 6 inch long clusters of soft-pink flowers in late spring. Wide-spreading light summer shade for very little care; a tough & adaptable tree. Light Pink Locust has smaller thorns than other locust, but it is not without them. Because of compound leaves, shade is filtered and dappled.
Extremely adaptable to varied soils and conditions; will grow practically anywhere but in wet soils. Tolerant of dry conditions and saline soils. It requires full sun, low watering (drought tolerant), and will live in poor soil.
