Juglans nigra, commonly known as the black walnut, is a deciduous tree native to eastern North America. It can grow up to 100 feet tall and is recognized for its dark, furrowed bark and large, compound leaves. The tree produces a hard, round nut that is encased in a green husk, which turns black as it ripens. The wood of Juglans nigra is highly valued for its rich color and durability, making it popular for furniture and cabinetry. Additionally, the nuts are edible and are often used in baking and cooking, while the tree itself provides habitat for various wildlife species.
