Value & Sustainability

Estimated Market Value
$8.00 to $14.00 per board foot depending on grade, width, and sapwood percentage.
Wood Age Estimate
Recently rough-sawn lumber, likely harvested and milled within the last 1–3 years.
Sustainability Status
Least Concern (IUCN); widely available and sustainably harvested in North America. Not listed on CITES appendices.

Common Uses

Furniture, cabinetry, interior trim, gunstocks, turned objects, veneer, and custom woodworking projects.

Geographic Origin

Eastern North America, widely distributed across the central and eastern United States.

Workability

Easy to machine and work with hand tools. Glues, stains, and finishes exceptionally well, though heartwood can occasionally cause slight dulling of cutting edges.

Finish Recommendations

Clear coat, oil-based varnish, polyurethane, or penetrating oil (such as Tung oil or Danish oil) to highlight the rich natural color tones without mudding the grain.

Notable Features

Faint, characteristic sweet smell when worked. High stability after drying and highly prized dark brown coloration.
