Southern Yellow Pine (likely Longleaf or Loblolly Pine)
Pinus palustris (Longleaf) or Pinus taeda (Loblolly) · Softwood
- Type
- Softwood
- Origin
- Southeastern United States
- Hardness
- 690-870 lbf (Soft to Medium-Soft for a softwood, though hard compared to other pines)
- Durability
- Moderately Durable; heartwood has some natural resistance to decay, but wood used outdoors is typically pressure-treated (ACQ or MCA) for rot and insect resistance.

Grain Pattern
Straight but uneven grain with a distinct cathedral pattern in flat-sawn sections. Features prominent earlywood (wide, light bands) and latewood (dark, dense bands) transitions.
Color & Appearance
Heartwood is reddish-brown to orange; sapwood is yellowish-white. The sample shows signs of UV exposure, turning a deeper amber/brown color. It has a dull to medium luster.
Hardness (Janka)
690-870 lbf (Soft to Medium-Soft for a softwood, though hard compared to other pines)
Durability & Decay Resistance
Moderately Durable; heartwood has some natural resistance to decay, but wood used outdoors is typically pressure-treated (ACQ or MCA) for rot and insect resistance.
Value & Sustainability
- Estimated Market Value
- $1.50 - $3.00 per board foot for standard construction grade.
- Wood Age Estimate
- Relatively young (1-5 years since milling); shows minor checking (splitting) and surface weathering consistent with recent outdoor exposure.
- Sustainability Status
- Not listed on CITES or IUCN Red List; widely available and highly sustainable due to extensive plantation farming and FSC certification availability.
Common Uses
Residential construction, decking, fencing, structural framing, utility poles, and heavy timber construction.
Geographic Origin
Southeastern United States
Workability
Easy to work with both hand and machine tools. Resinous nature can clog sandpaper and gum up blades. Holds nails and screws well but may require pre-drilling near ends to prevent splitting.
Finish Recommendations
Penetrating oil stains or film-forming deck sealers are recommended for outdoor use. If painting, a primer is necessary to prevent resin bleed.
Notable Features
Distinctive resinous/turpentine scent when cut; high contrast between earlywood and latewood growth rings gives it a bold, striped appearance.
