Southern Yellow Pine (likely Longleaf or Loblolly)
Pinus palustris (Longleaf) or Pinus taeda (Loblolly) • Softwood (Gymnosperm)
Grain Pattern
Straight, medium-to-coarse texture with distinct, wide growth rings showing a clear transition between light earlywood and dark latewood; flat-sawn orientation.
Color Description
Heartwood is yellowish to reddish-brown; sapwood is pale yellow to nearly white. This sample exhibits blue-gray fungal staining (sapstain) and will darken to a deeper amber color over time with UV exposure.
Hardness Rating
690-870 lbf (Soft to Medium-Soft)
Durability Rating
Non-durable to Slightly Durable; sapwood is highly susceptible to rot, blue stain fungi (visible), and insect attack without chemical treatment.
Common Uses
Construction framing, pallets, crates, plywood, decking (if pressure-treated), and inexpensive furniture.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.00 - $2.50 per board foot (standard construction grade)
Wood Age Estimate
Modern/Recent (under 2 years); the presence of blue sapstain suggests it was recently milled and stored in humid conditions without kiln drying.
Sustainability Status
Least Concern (IUCN); widely available and harvested from managed plantations; FSC and SFI certified options common.
Workability
Works easily with both hand and machine tools, though resin/pitch can gum up blades and sandpaper. Glues and finishes well, though large latewood bands can cause uneven stain absorption.
Notable Features
Distinctive resinous/pine scent; contains resin canals; highly susceptible to blue stain fungi which affects aesthetics but not structural integrity.
Finish Recommendations
Seal with a washcoat of shellac before staining to prevent blotching; polyurethane or lacquer recommended for protection. Blue stain might require opaque paint if a uniform look is desired.
Identification Confidence
High; the wide, prominent growth rings, color, and characteristic blue-gray fungal sapstaining are diagnostic of Southern Yellow Pine utility lumber.
