The black locust is a member of the important family of bee plants, the legumes. The legumes, or pea family, include several trees, the mimosa, redbud, Kentucky coffeetree, and the honey locust. The honey locust is the tree of similar appearance, but with eight-inch thorns on the trunk. The honey locust produces flowers that smell like honey, but the tree usually doesn’t produce enough nectar to make a surplus of honey for the beekeeper. Some of the other legumes are clover, soybeans, and peanuts. The black locust is truly a beautiful and useful tree.
