Black locust is a medium tree with deeply furrowed bark, compound leaves, and fragrant white flower clusters in late spring. Sharp thorns often occur on young twigs.
Habitat and range
In Maryland, black locust is frequent in old fields, roadsides, and disturbed sites, especially on dry, rocky soils. It can spread aggressively by root suckers and seed.
Uses and significance
The wood is extremely rot‑resistant and used for posts, rails, and outdoor structures. Flowers provide nectar for honeybees, and the tree is sometimes planted to stabilize poor soils.
