Description:
Black Walnut is a large deciduous tree with fragrant leaves and furrowed bark. It produces round, edible nuts in the fall; nuts can be messy when they fall to the ground. Black Walnut is the preferred host of luna and regal moths. Its roots produce chemicals called juglones, which deter growth of certain other plants; avoid planting it near fruit trees, flower beds, and vegetable gardens. Black Walnut wood is highly prized for furniture. Use it as a shade tree.
