Honour Roll of Trees
Black Locust is native to the eastern United States. While not native to southern Ontario, it has been extensively planted there, often in areas with degraded soil, since Black Locust is a legume and fixes its own nitrogen. It produces fragrant, showy white flowers in the spring that are very attractive to bees. Seeds are produced in pods. It also often reproduces by root sprouts. The wood is dark, dense and very resistant to decay. Leaves are compound and twigs have small rose-like thorns. It is commonly attacked by the locust borer which reduces suitability of the wood for many end uses as well as suitability of the tree for landscape planting.
