The black walnut tree, also known as the American walnut, is native to North America. Trees range in height from 70-150 feet and have a diameter of 2-4 feet. The compound leaves are between 1 and 2 feet long. This tree is prized for its beautiful wood and the tasty nuts which are avidly harvested in the autumn. The tree has large, pinnately compound leaves, 12 to 24 inches long with 15 to 23 leaflets. The leaf stems are covered with fine hairs but are smoother than butternut. The fruit is a large, rounded, brownish-black nut with a hard, thick, finely ridged shell enclosing a rich, oily kernel. The nut is black and rigid with the kernel having a high-quality taste. The kernel is edible and highly nutritious. The nut is enclosed in a solid, non-splitting husk, and is borne on the tree singly or in pairs.
