Grain Pattern

Usually straight to interlocked, with coarse texture and conspicuous growth rings; this image shows bark and branching only, not sawn grain.

Color & Appearance

Heartwood is yellowish to olive-brown, often darkening with age; sapwood is narrow, pale yellow to cream, with moderate luster.

Hardness (Janka)

1,700 lbf Janka; Hard.

Durability & Decay Resistance

Very Durable; heartwood has strong resistance to decay and many insects, especially outdoors.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $6–15 per board foot for sound, dry lumber; figured or exceptional stock 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
Not determinable from a standing-tree photograph; visible trees appear mature, but sample age cannot be established.

Common Uses

Fence posts, poles, outdoor furniture, decking, flooring, joinery, turnery, and tool handles.

Geographic Origin

Eastern and central North America; widely planted and naturalized elsewhere.

Workability

Machines and turns well but is hard and can blunt tools; interlocked grain may tear out. Pre-drilling is advisable; gluing is generally satisfactory.

Finish Recommendations

Sand carefully, seal end grain, and use penetrating oil, exterior varnish, or polyurethane; test finishes because heartwood color varies.

Notable Features

Very dense, strong, durable heartwood; often has a distinctive sweet or mildly floral odor when freshly cut.
