Southern Yellow Pine
Pinus palustris (Longleaf), Pinus echinata (Shortleaf), Pinus taeda (Loblolly), Pinus elliottii (Slash) • Softwood
Grain Pattern
Straight, uneven grain with prominent latewood (summerwood) growth rings. Features a heavy, coarse texture and distinct cathedral patterns when flat-sawn.
Color Description
Heartwood ranges from reddish-brown to orange; sapwood is yellowish-white. The wood displays high contrast between the lighter earlywood and darker latewood rings. Darkens with age and UV exposure.
Hardness Rating
690 lbf (Soft to Medium-Soft); among the hardest of the softwoods.
Durability Rating
Non-durable to Slightly Durable. Moderately resistant to decay in the heartwood, but sapwood is highly susceptible to rot and insects unless pressure-treated.
Common Uses
Structural framing, subflooring, decking, pallets, utility poles, heavy construction, and rustic furniture.
Geographic Origin
Southeastern United States.
Market Value & Sustainability
Estimated Market Value
$1.00 - $3.00 per board foot for standard dimensional lumber; higher for select grades or vertical grain.
Wood Age Estimate
The sample appears recently cut (fresh stock) based on the bright color, lack of oxidation/patina, and sharp mechanical saw marks on the end grain.
Sustainability Status
Highly sustainable; widely available, managed in massive commercial plantations, and not CITES or IUCN threatened.
Workability
Easy to work with hand and machine tools, though high resin content can gum up saw blades and sandpaper. Takes nails and screws well but can split if not pre-drilled near ends.
Notable Features
Distinctive resinous/turpentine scent. Recognized by the high density of dark latewood rings which are harder than the surrounding earlywood.
Finish Recommendations
Accepts most finishes; however, resin/pitch bleeding may occur. A shellac-based sealer is often used to prevent resin from interfering with topcoats. Takes paint well after priming.
Identification Confidence
High; the wide, dark latewood bands and coarse texture shown in the end-grain photo are classic diagnostic features of the Southern Yellow Pine group.
