Black Walnut

American Black Walnut, Juglans nigra, is a dark, heavy and strong hardwood. Despite its strength, it is not difficult to work or split. It is often used in furniture, cabinet making, flooring, coffins, guns and for other woodworking uses. Available in Britain from American imports as early as 1610, it was not until the mid 19th century that the timber was prized for its appearance. The timber is usually steamed to even out the colour variation between the heartwood and sapwood.

The tree grows up to 40-50m and has trunks up to a diameter of 60″. Black walnuts, edible fruit with health benefits, are produced by the tree. The tree most commonly grows in Mid and Eastern USA and Canada.
