Grain Pattern
Distinctive flat-sawn cathedral grain with strongly contrasting earlywood and latewood bands; knots and irregular grain are visible. The dark/light striping may be enhanced by wire-brushing or staining.
Color & Appearance
Heartwood is naturally greenish-yellow to brown and often darkens with age; sapwood is pale yellow. This sample appears substantially darkened or stained, with moderate figure and low-to-moderate luster.
Hardness (Janka)
1,700 lbf Janka; Hard.
Durability & Decay Resistance
Very Durable; heartwood has strong resistance to decay and insects, especially outdoors, though sapwood is less resistant.
Value & Age
Approximately $8–$18 per board foot for clear, dry domestic stock; figured or exceptionally wide boards may cost more.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot be reliably dated from a photograph; the surface suggests an older, finished or weathered board, but not necessarily antique.
Common Uses
Outdoor furniture, fence posts, decking, flooring, boat components, turnery, tool handles, and specialty furniture.
Geographic Origin
Native to the Appalachian and central/eastern United States; widely planted and naturalized elsewhere.
Workability
Dense and hard but machines reasonably well; interlocked grain can tear out, and it can blunt cutters. Pre-drilling is recommended; it sands and glues adequately when clean and dry.
Finish Recommendations
Test finishes on a sample because dark staining can bleed or appear uneven; use a wash coat or sanding sealer, then oil, lacquer, or polyurethane. Exterior use benefits from a penetrating outdoor finish.
Notable Features
Exceptional outdoor durability, high density, prominent growth-ring contrast, and attractive rustic knots; may have a mild sweet odor when freshly cut.
