A deciduous hardwood tree, Juglans regia, known for its timber and its nuts. The English walnut is native to Europe and parts of Asia. The wood from the English walnut tree is a uniform, deep brown color with a medium texture and a close, straight grain. It is strong but easy to work and polishes to a high gloss. Walnut wood is used for furniture, veneers, cabinets, paneling and gum stocks. Burrs, called oyster veneers, are especially prized in the furniture trade. Other portions of the tree also have commercial value. The nut kernels are used for cooking and the pale yellow fast-drying oil expressed from the nuts is used for artists paints. Tannins and dyes are extracted from the walnut hulls and shells that produces a brown color. Ground nut shells have been used as a soft abrasive and a plastic filler.
