Endemic to tropical West Africa, African Walnut is a large tree growing to heights of 150 feet. African Walnut logs typically have long branch-free trunks with diameters up to 4 feet. These trees will provide lots of lumber in decent lengths and widths. The grain is usually interlocked which will produce a shimmering ribbon stripe on quartersawn material.
The heartwood colours range from a golden yellow to reddish brown, often overlayed with dark black streaks. Upon exposure to light and air, the colour will darken to a deeper brown. The sapwood is a yellow to light gray and is sharply demarcated from the heartwood. Occasionally, there is a narrow colour transition zone present between the sapwood and the heartwood.
