Common Uses
Fence posts, outdoor furniture, decking, flooring, turnery, tool handles, and firewood.
Geographic Origin
Native to the Appalachian and central/eastern United States; widely planted and naturalized elsewhere.
Workability
Hard and abrasive but machines reasonably well; predrilling is advisable, and interlocked grain can tear during planing. Glues and finishes adequately when dry and clean.
Finish Recommendations
For exterior use, use a penetrating exterior oil or stain; for interior work, sand thoroughly and apply oil, shellac, lacquer, or polyurethane.
Notable Features
Distinctive rope-like, deeply furrowed gray-brown bark; dense, heavy wood with excellent outdoor longevity.
