Description:​ Black locust trees are within the Fabaceae family of trees and have nitrogen fixing attributes, which is a reason they were planted in the first place. Now listed as an invasive plant in Minnesota, the black locust is tolerant of most site conditions. They can spread by means of seed distribution or by root suckers, forming colonies. They are aggressive, can experience sucker growth, and are known for their weak wood and branch structure. Black locust is not a recommended tree for planting.
