Distribution
Walnut grows throughout most of the eastern half of the United States. The tree prefers moist, well drained soils, particularly along streams, and is usually found scattered in mixed forests.
General Description: The sapwood is whitish to a yellowish-brown. The heartwood varies from a pale brown to a chocolate brown in color, and can even have a purple tint. It is common of the wood to be steamed during the kiln drying process, this darkens the sapwood to make it more of a uniform color with the heartwood. The grain is slightly open, but usually straight, with a semi-coarse but uniform texture.
