Southern Yellow Pine (likely Loblolly or Shortleaf)
Pinus taeda / Pinus echinata • Softwood
Grain Pattern
Straight but coarse with prominent, wide latewood bands creating a distinctive striped cathedral/flat-sawn appearance; texture is uneven due to the density difference between earlywood and latewood.
Color Description
Heartwood is typically reddish-brown, while sapwood is yellowish-white to pale yellow. This sample shows a high percentage of pale yellow sapwood with some darker bluish-gray streaking, likely caused by sap-stain fungi (blue stain).
Hardness Rating
690 lbf (Soft to Medium-Soft); it is one of the hardest softwoods commonly available in North America.
Durability Rating
Non-durable to Slightly Durable; the sapwood is highly susceptible to decay and insect attack if not pressure-treated.
Common Uses
General construction, framing, pallets, crates, plywood, flooring, and when pressure-treated, used for decks, fences, and utility poles.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.00 - $2.50 per board foot (standard construction grade)
Wood Age Estimate
Relatively young lumber, likely processed within the last 1-2 years; shows mill marks and blue stain indicating it was likely stored or processed under high moisture conditions recently.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available and intensively farmed in plantations, making it a highly sustainable building material.
Workability
Easy to work with both hand and machine tools; however, his resin/pitch can gum up saw blades and sandpaper. Nailing and screwing are easy but the density difference between bands can cause bits to wander.
Notable Features
Distinctive resinous scent; contains high amounts of resin (pitch); the blue staining visible is an aesthetic defect caused by fungi that does not significantly affect structural integrity.
Finish Recommendations
Accepts most finishes well, though a pre-stain wood conditioner is recommended to prevent blotching. Film-forming finishes like polyurethane are common for flooring applications.
Identification Confidence
High; the wide latewood bands, conspicuous resin canals, and presence of blue stain are classic diagnostic features of Southern Yellow Pine sapwood.
