American Black Walnut

The heartwood of American Walnut can be light greyish-brown, dark brown or purplish-black. The sapwood can be almost white to a yellow, creamy-brown. The slightly open grain is typically straight, but can be curly or wavy. The texture is usually coarse, but develops a lustrous patina in time. Burrs (burls), stump wood and crotches produce notable mottled, curly and wavy figure.

Walnut can be extremely knotty - especially with wider boards (widths exceeding 120mm). All timber varies in appearance from piece to piece but with Walnut the variance can be significant even with wood from the same batch or even board. This is part of its character and adds to the natural beauty of the wood and is often why it is chosen. There can be a need to fill the knots with a dark or ebony filler
