Black Locust (Robinia pseudoacacia)
Black locust is a fast-growing native tree valued for its toughness, adaptability, and fragrant spring flowers. In cities like Buffalo, it is known for its ability to tolerate poor soils, drought, pollution, and difficult urban conditions where many other trees struggle. Its durable wood and nitrogen-fixing roots also make it useful in restoration and low-fertility sites. While highly resilient, black locust is best planted in areas where its spreading habit and occasional suckering can be managed.
Key Features:
Fragrant white flower clusters in late spring that attract pollinators
Extremely tolerant of poor soils, drought, and urban stress
Nitrogen-fixing roots improve soil quality over time
How big will I grow?

How to Care for Me?
Hackberry requires minimal maintenance once established. Prune in early years to develop a strong structure, as branches can be somewhat weak if not properly trained. It is generally pest- and disease-tolerant, though it may occasionally experience nipple gall or leaf spot, which are mostly cosmetic. Water regularly during establishment, especially in the first 2–3 years.
