Grain Pattern
Exceptionally straight, fine, tight, and uniform vertical grain (quarter-sawn/edge-grain cut) with high growth-ring density (20+ rings per inch).
Color & Appearance
Heartwood ranges from light reddish-brown to orange-pink with distinct, narrow dark brown latewood lines; sapwood is yellowish-white. Darkens to a warm amber/honey tone with UV exposure.
Hardness (Janka)
710 lbf (Soft)
Durability & Decay Resistance
Moderately Durable to Durable; good natural resistance to decay, rot, and weathering compared to most softwoods.
Value & Sustainability
- Estimated Market Value
- $12.00 to $18.00 per board foot for high-grade clear vertical grain (CVG) old-growth stock.
- Wood Age Estimate
- Estimated 50–100+ years old architectural component, harvested from old-growth or mature secondary-growth timber given the narrow growth rings.
- Sustainability Status
- IUCN status: Least Concern. Old-growth timber is highly regulated and restricted; plantation-grown and FSC-certified Douglas Fir is widely available.
Common Uses
Architectural millwork, door and window frames, interior/exterior trim, structural timber, boat building, sauna benching, and flooring.
Geographic Origin
Pacific Northwest of North America (United States and Canada).
Workability
Cuts and sands easily with sharp tools; holds nails and screws well. High contrast between soft earlywood and hard latewood can cause ridging if sanded unevenly or tearout during planing across grain.
Finish Recommendations
Accepts clear penetrating oils, varnish, shellac, and polyurethane extremely well. A sanding sealer or conditioner helps ensure even stain absorption.
Notable Features
Distinctive resinous/sweet odor when freshly cut; prominent contrast between earlywood and latewood bands; high strength-to-weight ratio.
