Grain Pattern
Mostly straight to gently flowing face grain with a live-edge contour. Shows fine growth ring boundaries, minor cross-grain movement around live knots, and slight cathedral banding visible near the sapwood transition.
Color & Appearance
Heartwood ranges from rich golden-tan to warm chocolate brown with darker growth rings. The sapwood is distinctly lighter, pale cream-to-yellowish along both live edges. The wood darkens slightly and develops a rich patina with age and light exposure.
Hardness (Janka)
1010 lbf (Medium)
Durability & Decay Resistance
Durable to Very Durable regarding heartwood decay resistance; moderately resistant to insect attack, though sapwood is susceptible to powder post beetles.
Value & Sustainability
- Estimated Market Value
- $10.00 - $18.00 per board foot for live-edge slabs (varies by width, figure, and dryness).
- Wood Age Estimate
- Freshly milled to recently harvested live-edge slab section; wood itself likely came from a tree aged 40 to 70 years based on growth ring curvature.
- Sustainability Status
- Not CITES listed; classified as Least Concern on the IUCN Red List. Widely available from sustainable domestic sources and urban lumber reclamation.
Common Uses
Live-edge furniture (slabs, coffee tables, dining tables), high-end cabinetry, gunstocks, woodturning, acoustic guitars, decorative veneers, and small craft items.
Geographic Origin
Eastern and Midwestern United States, southern Ontario (Canada), widely cultivated across North America.
Workability
Excellent workability with both hand and power tools. Planes smooth, sands to a high luster, holds screws and nails well, and glues without issue. Dust can occasionally cause minor mild irritation.
Finish Recommendations
Penetrating oils (Tung oil, Danish oil, or Hardwax oils like Rubio Monocoat) highlight the color contrast between sapwood and heartwood beautifully. Clear satin polyurethane, lacquer, or shellac also perform exceptionally well.
Notable Features
Distinctive contrast between pale sapwood and dark heartwood on live-edge slabs, pleasant nutty aroma when worked, fine natural grain sheen, and stable dimensional properties.
