Robinia pseudoacacia
Black Locust (Robinia pseudoacacia) is a fast-growing deciduous tree native to North America. Its branches are often armed with long, sharp spines. It produces fragrant white flowers from late spring to summer, followed by brown pods that are dark on the inside containing several seeds. It is widely grown in gardens and parks, where it is valued for its ability to quickly grow in poor soil. Its wood is durable, strong, and insect-resistant, making it suitable for fenceposts and firewood. It also makes a great nectar source for beneficial pollinators like honeybees.
