Southern Yellow Pine
Pinus echinata, P. elliottii, P. palustris, or P. taeda • Softwood
Grain Pattern
Coarse, straight grain with prominent, wide growth rings showing a distinct contrast between light earlywood and dark latewood; features a circular cathedral pattern around a large resinous knot.
Color Description
Sapwood is yellowish-white to pale yellow; heartwood is reddish-brown. The knot shown exhibits high resin concentration (fatwood), appearing much darker and more saturated with age and oxidation.
Hardness Rating
690 lbf (Soft) for Shortleaf Pine to 870 lbf (Medium) for Longleaf Pine
Durability Rating
Non-durable to Slightly Durable; susceptible to decay and insect attack if not pressure-treated for outdoor use. Heartwood from old-growth trees is more rot resistant.
Common Uses
Structural framing, construction lumber, decking (if treated), flooring, utility poles, and plywood. Highly resinous sections are used as fatwood for fire starters.
Geographic Origin
Southeastern United States, ranging from Texas to Virginia and south to Florida.
Market Value & Sustainability
Estimated Market Value
$1.00 - $3.00 per board foot depending on grade and dimensions.
Wood Age Estimate
Freshly cut or modern construction grade lumber, likely less than 2 years old, showing minimal graying or deep oxidation except for the resin-rich knot area.
Sustainability Status
Least Concern (IUCN); widely available and sustainably harvested from managed plantations; FSC certification is common.
Workability
Generally easy to work with hand and machine tools, though high resin content can gum up blades and sandpaper. It holds nails and screws well but can be prone to splitting.
Notable Features
Distinctive resinous scent; contains high amounts of pitch/sap. Incredibly strong for its weight, making it the preferred species for heavy structural construction in its range.
Finish Recommendations
Polyurethane or shellac; requires a sanding sealer or dewaxed shellac base coat if the wood is particularly resinous to prevent finish adhesion issues. Paints well once seasoned.
Identification Confidence
High; the wide growth rings, stark contrast between earlywood/latewood, and the dark, resinous knot are classic diagnostic features of Southern Yellow Pine.
