The mature Black Walnut tree often attains a height of 100 feet, with a trunk diameter up to 4 feet. Boles may be clear of branches to 50 to 60 feet. It grows throughout the Eastern United States, but in commercial quanties only in the Midwest.

The sapwood is whitish to yellowish brown. It is a common practice to steam or stain the sapwood to match the color of the heartwood. Heartwood varies from light grayish brown to deep chocolate brown to an almost black purplish brown. The grain is slightly open and usually straight, but may be wavy or irregular. Texture is usually coarse, but uniform. The wood is noted for its wavy, curly and mottled figures which are obtained from burls, crotches and stumpwood.

Black Walnut Walnut is one of the primary American woods for premium cabinetry and furniture (with cherry and mahogany). It is universally available although large, mature trees are getting scarcer and more expensive. Click to Enlarge Image
