Southern Yellow Pine (likely Loblolly or Longleaf)

Pinus taeda / Pinus palustrisSoftwood

Southern Yellow Pine (likely Loblolly or Longleaf)

Grain Pattern

Straight but coarse with a high contrast between earlywood and latewood; flat-sawn orientation showing prominent growth rings and some checking/splitting.

Color Description

Heartwood is reddish-brown with lighter yellowish-white sapwood. Shows significant darkening/patina due to UV exposure and oxidation, turning a deeper orange-brown over time.

Hardness Rating

690 lbf to 870 lbf (Soft to Medium Hardness)

Durability Rating

Durable (if pressure-treated) or Moderately Durable (heartwood only). Highly susceptible to rot if untreated and in ground contact.

Common Uses

Construction framing, decking, utility poles, flooring, plywood, and exterior trim.

Geographic Origin

Southeastern United States

Market Value & Sustainability

Estimated Market Value

$1.00 - $2.50 per board foot (standard dimensional lumber pricing)

Wood Age Estimate

10-20 years based on the heavy oxidation, surface checking (cracks), and weathering typical of an outdoor post.

Sustainability Status

Least Concern (IUCN); widely available as FSC certified; primary commercial timber in the US.

Workability

Easy to work with both hand and machine tools, though resin/sap can gum up blades and sandpaper. Large density differences between grain lines can cause uneven staining.

Notable Features

Distinct resinous (turpentine) scent when cut; high resin content makes it heavier and stronger than many other softwoods.

Finish Recommendations

Exterior-grade penetrating oil or solid stain for weather protection. Requires drying if pressure-treated before applying finish.

Identification Confidence

High. The wide, dark latewood bands and distinct color contrast are characteristic of the Southern Yellow Pine group, specifically in a construction lumber context.
