Walnut

Other Common Names: American Walnut or Eastern Black Walnut.

Northwest’s Walnut is grown in both the Glacial and Appalachian regions.

American Walnut is one of the scarcest and most coveted native hardwoods. It is in a class by itself. The sapwood of Walnut is nearly white, while the heartwood is light brown to dark, chocolate brown, often with a purplish cast and darker streaks. Northwest Walnut is steamed to enhance the chocolate brown heartwood and darken the sapwood. The wood is heavy, hard and stiff and with a high shock resistance. It is generally coarse textured and produces distinctive grain patterns.

Walnut is used for dining room and bedroom furniture, bookcases, desks, tables, cabinets, shotguns and rifles, and interior finishes.
