Grain Pattern

Tight, vertical/edge-grained (quarter-sawn appearance) with very narrow growth rings characteristic of old-growth conifers.

Color & Appearance

Deep amber to reddish-brown patina on the finished surface due to decades of aging and light exposure; newly exposed raw wood shows a lighter golden-tan color with contrasting darker grain lines.

Hardness (Janka)

Durability & Decay Resistance

Value & Sustainability

Estimated Market Value
$6.00 to $12.00 per board foot for reclaimed old-growth stock
Wood Age Estimate
Estimated to be 80 to 120+ years old based on the deep amber patina, tight old-growth growth rings, and context as vintage flooring.
Sustainability Status
Old-growth Heart Pine is primarily available as reclaimed material, making it an eco-friendly choice; new-growth is sustainably managed on plantations.

Common Uses

Historical and contemporary flooring, heavy timber framing, millwork, stair treads, and fine furniture.

Geographic Origin

Southeastern United States

Workability

Generally easy to work with hand and tools, though old-growth resin content can occasionally gum up saw blades and sandpaper; glues and finishes well.

Finish Recommendations

Penetrating oil finishes, polyurethane, or traditional shellac and wax work exceptionally well to highlight the deep amber chatoyance and rich grain.

Notable Features

High resin and pitch content providing natural decay resistance, distinctive tight growth rings, and rich aromatic scent when freshly cut.
