Juglans nigra
Black walnut (Juglans nigra) is a large deciduous tree native to parts of North America. It is typically found in woodlands, forests, and along the banks of rivers. The tree can reach heights up to 150 feet and has a grey-brown bark with deep furrows. Its compound leaves are dark green and deeply lobed. Black walnut fruits contain a thick, dark outer shell and a sweet edible nut. The nut was historically used by Native Americans as a source of food. Black walnut is now also appreciated for its strong, dark-colored wood used in many projects, from furniture to cabinets.
