Cultivation and Ecological Role
Black locust is easy to grow, tolerates poor soils and drought, and enriches the soil with nitrogen through its symbiosis with nitrogen-fixing bacteria. It is valued as an ornamental and honey plant but is considered invasive in some regions.
The black locust is a versatile plant with uses ranging from ornamental landscaping to herbal remedies. Its fragrant flowers are a boon for pollinators, and its medicinal qualities make it a valuable addition to natural remedies.
