Quaking aspen

Overview

Quaking aspen (Populus tremuloides) is a pale, very light and very soft northern hardwood, named for its leaves, which tremble in the lightest breeze. It is a utility timber used for boxes, crates, veneer and plywood, and as a plain pale board for rustic or painted work. Choose it where a bland, inexpensive pale wood is wanted and hardness does not matter.

Pros

• Easy to work with hand and machine tools.
• Pale, uniform colour with a straight, even grain.
• Does not split easily, per the Wood Database.
• Very light (about 415 kg/m3 dried).
• Glues and finishes well.
• Priced modestly within its range, with wide planks available.

Cons

• Very soft at 350 lbf, so it dents readily.
• Tends to leave fuzzy surfaces unless cutters are sharp and sanding goes to fine grits.
• Tends to warp and distort during drying.
• Poor nail-holding capability.
• Non-durable and susceptible to insect attack.
• Low natural lustre and little figure.

Variants and subspecies

• Quaking aspen is the species sold.
• It is in the genus Populus, with Eastern cottonwood; the Wood Database notes that Yellow poplar is not in that genus.

Working and finishing

The Wood Database says aspen is easy to work by hand or machine, but sharp cutters are necessary when planing to avoid fuzzy surfaces, and fine sanding may be needed afterward. It does not split easily and has poor nail-holding capability. It tends to warp and distort during drying, so buy kiln-dried stock and allow it to settle before final milling. It glues and finishes well.

Staining and finishing colour

Heartwood is light brown; wide sapwood is pale yellow to nearly white and blends gradually into it. The Wood Database says it glues and finishes well but gives no stain guidance. A soft, fuzzy surface can take colour unevenly, so test first. Painting is the easiest route to a uniform look.

Sustainability and handling

The Wood Database reports quaking aspen as not listed in the CITES Appendices (checked 2026-09-30) or on the IUCN Red List; Wikipedia's page gives Least Concern (2018). US-grown timber is still covered by the Lacey Act, which as amended in 2008 prohibits trade in plants and timber taken, possessed, transported or sold in violation of law (Wikipedia's summary of the Act); buy from dealers who can name the source. The Wood Database reports no health reactions beyond the standard risks of wood dust. The Wood Database's wood-dust article treats wood dust in general as an irritant or sensitizer and notes that fine dust can cause cumulative lung damage, so extract at the source and wear a respirator when sanding or machining.

Popular projects

Boxes and crates, veneer and plywood, painted or rustic furniture, and general utility work. The Wood Database lists boxes and crates, veneer, plywood and various utility purposes. It is also used for pulpwood in paper manufacture.

Buying notes

Aspen lumber is commonly harvested within its range, and wide planks should be modestly priced there, per the Wood Database. One seller lists it at $5.25 per board foot (January 2026); no other price was found, so check local yards. Buy kiln-dried stock and look for warp.
