Black Walnut (Juglans nigra)

Juglans nigra, commonly known as Black Walnut, is a large, stately deciduous tree native to the eastern and central United States. Known for its strong wood, valuable nuts, and broad canopy, Black Walnut can grow 50 to 80 feet tall with a wide-spreading crown. Its compound leaves provide light shade in summer, while its deep taproot and allelopathic properties (juglone production) influence nearby plant growth. Black Walnut is best suited to large properties, restoration projects, and native habitat plantings where it can provide food, shelter, and soil stabilization.
