Southern Yellow Pine
Pinus echinata / Pinus taeda • Softwood
Grain Pattern
Irregular and wavy around branch inclusions, typical of flat-sawn utility lumber. Exhibits prominent latewood bands and a large central sound knot with radial checking.
Color Description
Light yellow to tan heartwood with a pale sapwood; however, this sample shows significant blue stain (fungal discoloration) creating greyish-blue streaks and splotches throughout. Reddish-brown tone in the knot.
Hardness Rating
690 lbf (Soft)
Durability Rating
Non-durable; low resistance to rot and insect attack without chemical treatment. Highly susceptible to blue stain fungi if not dried quickly.
Common Uses
Residential construction, pallets, crates, utility shelving, framing, and Pressure Treated (PT) decking.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.50 - $2.50 per board foot (standard utility grade)
Wood Age Estimate
Modern material, likely milled within the last 1-2 years based on the fresh appearance of fungal staining and circular saw marks visible on the surface.
Sustainability Status
Highly sustainable; widespread plantation growth and common FSC/SFI certification. Not CITES listed.
Workability
Easy to work with both hand and machine tools. Resinous nature may gum up sandpaper and blades. High degree of sap can make finishing difficult if not properly dried.
Notable Features
Distinctive resinous/pine scent. Presence of sapwood 'blue stain' caused by Ophiostoma fungi, which affects aesthetics but generally not structural integrity. High resin content.
Finish Recommendations
Requires a sealer or washcoat of shellac to prevent resin bleed-through. Best suited for paint or opaque stains due to significant fungal discoloration.
Identification Confidence
High. The prominent growth rings, large resinous knot, and characteristic blue-staining patterns are definitive for a Southern Yellow Pine species used in utility applications.
