The black walnut tree (Juglans nigra) is a tall deciduous tree native to eastern North America. It is a member of the walnut family, which also includes the butternut (Juglans cinerea) and the heartnut (Juglans ailantifolia var. cordiformis). The black walnut tree is valued for its high-quality wood, edible nuts, and medicinal properties. In this article, we will explore the characteristics, uses, and benefits of the black walnut tree.
Characteristics of the Black Walnut Tree
The black walnut tree is a large, spreading tree that can grow up to 100 feet tall and 75 feet wide. It has a straight trunk that can be up to 4 feet in diameter, with a deeply furrowed, gray-brown bark. The leaves are compound and can be up to 2 feet long, with 11 to 23 leaflets that are lance-shaped and pointed at both ends. The leaves turn a bright yellow in the fall before dropping.
The black walnut tree blooms in the spring, producing long, greenish-yellow catkins that are 4 to 5 inches long. The male flowers are on the catkins, while the female flowers are small and inconspicuous, located at the base of the catkins. The nuts ripen in the fall and are encased in a thick, green husk that splits open when the nut is ripe. The nut inside is hard, smooth, and brown, with deep, convoluted furrows.
