Walnut, often known as Black Walnut, has a pale brown to dark brown heartwood with dark brown streaks (scientific name: Juglans Nigra). The sapwood ranges in colour from pale yellow-grey to white. There are also figured grain patterns. It has a medium texture, a moderate sheen, and grain that is straight but slightly uneven.
Hardwood Black Walnut Lumber is a high-end domestic hardwood prized for its deep colour and superior finish. Walnut grows periodically across the United States, and its price reflects the fact that it does not grow in stands and that felled logs must be hauled long distances in isolated places.
Walnut has an even, homogeneous texture that ranges from medium-fine to coarse. Patterning varies from straight to wavy and uneven on this relatively open grain. Heartwood is a mottled dark chocolate brown with a purple tint; sapwood is practically white and is frequently steam-stained at the sawmill to blend in with heartwood.
Walnut is a popular tree in the eastern United States. It has a high resistance to decay, although it is vulnerable to insect attack.
