locust tree

Robinia pseudoacacia
In the United States: Native · also called false acacia

Honeybees visit black locust primarily for its abundant, high-quality nectar during the brief late-spring bloom, yielding a light-colored surplus honey prized by beekeepers. The fragrant white flowers also offer limited pollen as a secondary reward. This nitrogen-fixing tree grows rapidly on poor soils but produces vigorous root suckers that require management to contain its spread.
