Longleaf Pine (Heart Pine)
Pinus palustris • Softwood (Conifer) / Reclaimed
Grain Pattern
Strongly defined flat-sawn cathedral patterns with heavy latewood bands. Features dense, straight growth rings visible in vertical sections and prominent resin-heavy grain lines.
Color Description
Aged heartwood shows a deep reddish-brown to orange-amber hue. The sapwood is typically narrower and lighter yellowish-white, though this sample shows significant darkening from aged finish and oxidation.
Hardness Rating
870 lbf (Medium - notably hard for a softwood)
Durability Rating
Moderately Durable; heartwood contains high resin content that provides decent rot and insect resistance compared to other softwoods.
Common Uses
Flooring (specifically historic tongue and groove), heavy construction timbers, cabinetry, wainscoting, and reclaimed furniture.
Geographic Origin
Southeastern United States (Coastal Plain from Virginia to Texas)
Market Value & Sustainability
Estimated Market Value
$8.00 - $15.00 per board foot (Reclaimed Heart Pine prices vary by width and grade)
Wood Age Estimate
80-120 years. The tight growth rings and deep oxidation beneath the finish indicate 'Old Growth' timber typical of early 20th-century construction.
Sustainability Status
Threatened in the wild; most high-quality material is sourced via reclamation (salvaged from old buildings/mills).
Workability
Generally easy to work, though high resin content can gum up sandpaper and saw blades. Dries well but can be prone to splitting if not pre-drilled. Tears can occur if tools are not sharp.
Notable Features
Distinctive 'turpentine' scent when cut. Very high resin content makes it more stable and harder than most pines. Known for its historical role in the American naval stores industry.
Finish Recommendations
Oil-based polyurethanes or tung oil to enhance the 'fire' and depth of the reddish grain. Shellac is an excellent sealer to prevent resin bleed.
Identification Confidence
High. The combination of dense earlywood/latewood contrast, classic 'cathedral' flat-sawn patterns, and the reddish-amber hue is diagnostic of aged Heart Pine, likely from a flooring application.
