Species and wood science

Black walnut

Black walnut is Juglans nigra, the North American walnut widely traded for furniture.

Its heartwood ranges from medium to dark brown, often with purplish or grey tones. Pale sapwood can create strong contrast.

Do not treat every walnut listing as black walnut. European walnut and Claro walnut are different species or groups.
