Robinia pseudoacacia, commonly known as the Black Locust, is a tree in the subfamily Faboideae of the pea family Fabaceae. Black locust is native to the southeastern United States, but has been widely planted and naturalized elsewhere in temperate North America, Europe and Asia and is considered an invasive species in some areas.
