Black Locust is a nitrogen-fixing native tree of the Appalachian region that has naturalized widely across North America and globally. Its fragrant white flower clusters in May are one of the most important nectar sources for honeybees, producing the prized black locust honey. Its wood is remarkably rot-resistant, lasting decades in soil contact.
