Grain Pattern

Straight, fine, uniform texture with weak or subtle growth rings, lacking figure or pronounced grain contrast.

Color & Appearance

Heartwood is off-white to light creamy brown; sapwood is almost white and blends seamlessly into heartwood. Luster is low to medium, and exposure to light causes slight darkening to light grayish-brown.

Hardness (Janka)

350 lbf (Very Soft)

Durability & Decay Resistance

Non-durable to perishable; very low natural resistance to decay, rot, and insect attack (susceptible to beetles and termites).

Value & Sustainability

Estimated Market Value
$2.50 - $4.50 per board foot for solid lumber; low commercial value as fine furniture lumber.
Wood Age Estimate
Living tree estimate: Mature specimen approximately 60 to 100+ years old, indicated by thick, deeply furrowed, dark bark along the lower trunk contrasted with smooth, pale upper bark.
Sustainability Status
Least Concern (IUCN Red List). Highly sustainable, abundant species spread via massive clonal root systems; non-CITES listed.

Common Uses

Pulpwood for paper, OSB/particleboard, matches, wooden crates, saunas (due to low thermal conductivity and non-splintering nature), chopsticks, and light utility lumber.

Geographic Origin

Native across cold and temperate regions of Northern North America, spanning Alaska and Canada down through the western United States to Mexico.

Workability

Easy to cut and shape, but prone to fuzzy surfaces when planed or sanded due to soft, fibrous structure. Glues and fastens well, though holding power for screws/nails is low.

Finish Recommendations

Requires careful sanding with sharp abrasive paper; blotch-prone, so a sanding sealer or pre-stain conditioner is recommended before applying oil, shellac, or clear lacquer finishes.

Notable Features

Extremely lightweight, does not splinter easily, low thermal conductivity, leaves flutter in light breeze on flattened petioles, grows in huge clonal colonies.
