Heart Pine (Longleaf Pine)
Pinus palustris • Softwood / Reclaimed
Grain Pattern
Straight, tight vertical grain (quarter-sawn appearance). Features high growth ring density typical of old-growth heartwood with distinct earlywood/latewood contrast.
Color Description
Vibrant reddish-orange to golden brown heartwood with pale yellow sapwood. Exhibits high luster and significant darkening (patina) to a deep amber-red over time and light exposure.
Hardness Rating
1,225 lbf (Hard for a softwood, comparable to some hardwoods)
Durability Rating
Durable. High resin content provides excellent natural resistance to rot, decay, and insects compared to other pines.
Common Uses
Flooring, heavy timber construction, cabinetry, paneling, and fine furniture.
Geographic Origin
Southeastern United States (Coastal Plain from Virginia to Texas)
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot for premium reclaimed vertical grain stock.
Wood Age Estimate
80-120 years. The narrow growth rings and deep oxidation suggest old-growth timber, likely installed in the early-to-mid 20th century.
Sustainability Status
Vulnerable (IUCN). Most Heart Pine on the market is reclaimed from historic buildings due to the depletion of original old-growth forests.
Workability
Generally good, though high resin content can gum up sandpaper and saw blades. Dulling of tools is moderate. Pre-drilling is recommended for nails/screws to avoid splitting.
Notable Features
Distinctive resinous 'piney' scent when cut; very high density and weight for a softwood; high tannin and resin content; excellent structural stability.
Finish Recommendations
Oil-based polyurethanes or tung oil to enhance the natural amber depth. Shellac is useful as a sealer to prevent resin bleed.
Identification Confidence
High. The extremely tight, vertical growth rings, characteristic reddish-amber color, and narrow board width are classic indicators of historic Heart Pine flooring.
