Black Walnut

Juglans nigraHardwood

Black Walnut

Grain Pattern

Commonly straight, though often seen with cathedral patterns in flat-sawn cabinet panels; visible medium-textured pores and moderate luster.

Color Description

Rich chocolate brown heartwood with hints of purple or gray; sapwood is typically creamy white but often stained to match heartwood in cabinetry. Darkens significantly with UV exposure and oil finishes.

Hardness Rating

1,010 lbf (Medium)

Durability Rating

Very Durable; heartwood is highly resistant to rot and decay, though sapwood is susceptible to insect attack.

Common Uses

High-end furniture, cabinetry, interior trim, gunstocks, veneer, flooring, and musical instruments.

Geographic Origin

Central and Eastern United States and Southern Ontario, Canada.

Market Value & Sustainability

Estimated Market Value

$12.00 to $18.00 per board foot for 4/4 select grade lumber.

Wood Age Estimate

Modern manufacture (5-20 years), based on the clean machine-profiled edges and contemporary hardware visible on the cabinet assembly.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC certification common.

Workability

Excellent workability with both hand and machine tools; glues, stains, and finishes well, though it can occasionally exhibit tearout on highly figured sections.

Notable Features

Distinctive faint, spicy scent when worked; contains juglone which can be a mild irritant; famous for its unique dark natural coloring among North American hardwoods.

Finish Recommendations

Polyurethane or lacquer for cabinetry durability; oil-based finishes are preferred to bring out the depth and warmth of the grain.

Identification Confidence

Medium-High; the deep brown color, pore structure, and application in a raised-panel cabinet door are highly characteristic of North American Black Walnut.
