Southern Yellow Pine
Pinus palustris (and related species) • Softwood
Grain Pattern
Predominantly straight, coarse grain with distinct flat-sawn cathedral patterns appearing around knots. The growth rings show a sharp contrast between earlywood and latewood.
Color Description
Heartwood is reddish-brown to orange; sapwood is yellowish-white. It exhibits a naturally low luster and tends to darken to a deeper amber or tan color over time with UV exposure.
Hardness Rating
690 lbf (Soft)
Durability Rating
Moderately Durable; heartwood has some natural decay resistance, but sapwood is susceptible to rot and insect attack without pressure treatment.
Common Uses
Residential construction, framing, decking, pallets, structural timbers, and rustic furniture.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.50 - $3.00 per board foot (standard construction grade)
Wood Age Estimate
Relatively recent/modern (less than 5 years). The wood shows rough-sawn mill marks and minimal oxidation, suggesting it is newer construction-grade lumber.
Sustainability Status
Not CITES listed; ranked as Least Concern on the IUCN Red List. Widely available from FSC-certified managed timberlands.
Workability
Generally easy to work with both hand and machine tools, though resin/pitch can clog sandpaper and gum up blades. Large knots can cause localized tearout during planing.
Notable Features
Distinctive resinous pine scent; high resin content can affect glue adhesion and finishing. Often contains large, dark knots as seen in the sample.
Finish Recommendations
Requires a sealer or wood conditioner if staining to prevent blotchiness. Polyurethane or varnish is recommended for protection. If used outdoors, pressure treatment or specialized exterior oils are necessary.
Identification Confidence
High; the combination of prominent latewood bands, large knots, resinous appearance, and rough-sawn texture is characteristic of commercial Southern Yellow Pine.
