Black Locust, also known as False Acacia, is one of North America's most valuable and historically important native trees. Native to the Appalachian and Ozark regions of the United States, this fast-growing deciduous tree is admired for its fragrant white flowers, attractive foliage, exceptional durability, and remarkable adaptability.

Mature trees typically reach 40 to 80 feet in height with an open, irregular crown that provides filtered shade. The pinnate leaves consist of numerous small leaflets that create a delicate, almost tropical appearance despite the tree's rugged nature.

During late spring, long drooping clusters of fragrant white flowers cover the tree. Resembling Wisteria blossoms, these flowers produce a sweet perfume that can be detected from considerable distances and attract large numbers of pollinators.

The combination of graceful flowers and durable character makes Black Locust one of the most unique native landscape trees available.

Black Locust offers a rare combination of beauty and toughness. Its fragrant spring flowers rival many ornamental trees, while its durability, rapid growth, and adaptability make it one of the most practical native shade trees available.

Some fence posts made from Black Locust wood have remained in service for over 100 years without treatment. This incredible natural resistance to decay has earned the tree a legendary reputation among farmers, homesteaders, and woodworkers, making it one of the most durable native hardwoods ever grown in North America.
