Value & Age

Estimated Market ValueNot an official valuation

$6.00 to $10.00 per board foot depending on thickness and live-edge premium.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
The sample appears recently milled and finished with an oil or wax, estimated at 1-5 years post-processing based on the brightness of the earlywood and lack of deep oxidation on the cut faces.

Common Uses

Boat building, shingles, siding, fence posts, decking, outdoor furniture, and specialty gift items/wood crafts involving live-edge designs.

Geographic Origin

East Coast of the United States, primarily in freshwater swamps and bogs from Maine to Florida.

Workability

Very easy to work with both hand and machine tools. It planes and sands very smoothly, though its softness makes it prone to denting and marring. Glues and finishes well.

Finish Recommendations

Clear oils, shellac, or polyurethane. Light oils are recommended to preserve the natural scent if the item is for indoor use; outdoor items require UV-resistant sealers to prevent graying.

Notable Features

Distinctive, pleasant aromatic scent similar to other cedars; very lightweight with excellent dimensional stability; has a high oil content that aids in moisture resistance.
