Grain Pattern

Straight to irregular grain with a prominent coarse texture, often displaying striking cathedral patterns when flat-sawn or pronounced medullary rays (flake) when quarter-sawn.

Color & Appearance

Heartwood is a light to medium brown, often with an olive cast; sapwood is significantly lighter, nearly white to pale yellowish-brown, developing a rich amber patina over time.

Hardness (Janka)

1360 lbf (Hard)

Durability & Decay Resistance

Very Durable, with exceptional resistance to decay and moisture penetration due to tyloses present in the heartwood vessels.

Value & Sustainability

Estimated Market Value
4.00 to 8.00 USD per board foot for standard lumber, significantly higher for quarter-sawn or specialized veneer grades.
Wood Age Estimate
Estimated to be derived from a mature tree approximately 120 to 180 years old, based on the thick, deeply furrowed bark patterns.
Sustainability Status
Not listed on CITES appendices or the IUCN Red List; widely abundant, sustainably managed, and readily available with FSC certification options.

Common Uses

Fine furniture, high-end cabinetry, residential and commercial flooring, timber framing, boat building, and tight cooperage (whiskey barrels).

Geographic Origin

Eastern and Central North America

Workability

Generally favorable workability with both hand and machine tools, though it has a high tendency to split when nailing or screwing (pre-drilling required) and reacts with iron to form blue-black stains.

Finish Recommendations

Accepts stains, oils, varnishes, and lacquers exceptionally well; water-based finishes help preserve the natural light color, while oil-based finishes enhance warm amber tones.

Notable Features

Contains closed cellular structures (tyloses) making it waterproof, high tannin content providing natural rot resistance, and characteristic broad medullary rays.
