Black Walnut (Juglans Nigra)

The Black Walnut (Juglans nigra) is a large, handsome, fast-growing deciduous tree with a single erect trunk and broad crown. Produces dark-brown edible nuts and highly valued dark timber. Intolerant of clay and poor drainage — requires a sheltered site with good, rich, free-draining soil. Cold and frost tolerant. Hardy. Although self-fertile, planting another walnut variety nearby will improve crops. Grows to 15–20m at maturity.
