The Black Walnut is also sometimes known as the American Walnut.
The Black Walnut is a large tree that produces prized walnuts. This tree does best on deep, fertile and well drained soils, but will tolerate clay and sandy soils as well.
It is important to note that the roots of this tree generate a substance called juglone. This substance can be toxic to other trees or plants planted near a black walnut and may even cause them to perish. Contact your local county forester or university extension office for more information on acceptable trees and shrubs that will grow near this tree.
