Populus tremuloides Michx. produces Canadian aspen, otherwise known as aspen or quaking aspen. This occurs fairly widely from Newfoundland and Nova Scotia to Alaska, and from northern New England to Minnesota and southwards along the Appalachians. The weight of dried timber is about 450 kg/m³.
The tree is normally from 15m to 18m tall, with a diameter of about 0.3m.
A light but relatively strong timber with a light uniformed colour with little colour difference between sapwood and heartwood.
Requires care to avoid warping and twisting during drying.
Medium - The timber works easily, although there may be a tendency to bind on the saw. A smooth surface can be obtained, but there is a tendency for the fibres to tear in sawing, and sharp thin edged tools are needed to avoid woolly surfaces in planing. The wood can be nailed, screwed, glued, stained and finished with the usual treatments satisfactorily.
