Straight and consistent with subtle wavy characteristics; primarily flat-sawn with visible cathedral peaking and a uniform fine texture.

Rich brownish-purple heartwood with hints of red; the sapwood is cream-colored to pale yellow. The heartwood will likely lighten slightly and take on a more golden hue over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to decay and rot, though susceptible to insect attack (beetles/borers).
Common Uses
High-end furniture, cabinetry, veneer, interior trim, flooring, gunstocks, and turned objects.
Geographic Origin
Central and Eastern United States and Southeastern Canada.
Market Value & Sustainability
Estimated Market Value
$12.00 to $18.00 per board foot, depending on width, clarity, and regional availability.
Wood Age Estimate
Relatively fresh/modern lumber; the lack of deep oxidation, mechanical saw marks, or heavy patina suggests it was milled within the last 1-5 years.
Sustainability Status
Not listed on CITES Appendices or 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 exceptionally well. It can exhibit some tearout on figured sections but is generally cooperative.
Notable Features
Distinctive mild, spicy scent when worked; contains juglone which can be an allergen; high luster and exceptional dimensional stability once seasoned.
Finish Recommendations
Oil-based finishes (tung or linseed) or clear polyurethane are highly recommended to enhance the deep color; wax or shellac provide a beautiful natural sheen.
Identification Confidence
High; the distinctive chocolate-brown color, pore structure visible on the face grain, and typical walnut sapwood transition are highly diagnostic.
