Grain Pattern
Straight, coarse grain with prominent growth rings and cathedral figure. Large knots visible on the face grain.
Color & Appearance
Originally yellowish-white to reddish-brown; currently weathered to a silver-grey and mossy green due to severe UV exposure, biological growth, and oxidation.
Hardness (Janka)
690 lbf (Soft)
Durability & Decay Resistance
Moderately Durable (if treated). The sample shows significant checking and weathering, suggesting the chemical protection is leaching over time.
Value & Sustainability
- Estimated Market Value
- $1.50 - $2.50 per board foot (Standard pressure-treated dimensional lumber)
- Wood Age Estimate
- 10-15 years. The severe surface checking, lichen growth, and deep grain erosion indicate long-term exposure to the elements.
- Sustainability Status
- Least Concern (IUCN). Highly sustainable and widely harvested from managed plantations in the US.
Common Uses
Outdoor decking, fencing, utility poles, framing, and light construction.
Geographic Origin
Southeastern United States.
Workability
Easy to work with power tools; can be gummy due to resin content. High risk of splintering in its current weathered state.
Finish Recommendations
Solid color deck stain or penetrating oil-based sealer after deep cleaning and sanding to remove the oxidized layer.
Notable Features
Distinctive resinous scent when cut; high sap content; contains chemical preservatives (likely MCA or ACQ) which requires safety precautions when handling.
