Grain Pattern
Straight to irregular grain with a coarse, uneven texture. Ring-porous growth rings are clearly visible on the end grain.
Color & Appearance
Freshly cut heartwood is a striking bright golden-yellow to bright orange, which darkens significantly upon exposure to UV light and air, eventually weathering to a rich dark brown or gray over time. The sapwood is a narrow, pale yellow band.
Hardness (Janka)
2,620 lbf (Extremely Hard)
Durability & Decay Resistance
Very Durable. Exceptional natural resistance to rot, decay, and insect attacks, often lasting for decades in direct contact with soil.
Value & Sustainability
- Estimated Market Value
- $5.00 to $10.00+ per board foot depending on dimensions and figure.
- Wood Age Estimate
- Estimated between 30 to 50 years based on ring count visibility and log diameter.
- Sustainability Status
- Least concern, abundant in its natural range and frequently cleared as a nuisance farm tree, not listed on CITES or IUCN red lists.
Common Uses
Fence posts, archery bows, turnings, primitive woodworking, mallets, accent pieces, and natural dye extraction.
Geographic Origin
Native to south-central North America (primarily Texas, Oklahoma, and Arkansas), but widely naturalized throughout the United States.
Workability
Very difficult to work with hand or machine tools due to its extreme hardness and density. It rapidly dulls cutting edges, though it turns well on a lathe and takes fine details.
Finish Recommendations
Takes oils and clear finishes very well, though finishes that block UV light (like UV-inhibiting spar varnish) can help preserve the vibrant yellow color longer before it browns.
Notable Features
Contains high levels of natural chemical compounds (such as morin) giving it bright yellow color and remarkable rot resistance. It is extremely heavy, dimensionally stable once dry, and has high shock resistance.
