The Trembling Aspen is a medium-sized tree that grows up to 25 m high and 40 cm in diameter. The leaves are roughly 3-7 cm long, broadly oval to kidney-shaped with a short and sharp tip, and a rounded base. The upper surface of the leaf is deep green, with a paler underside. The stalks are flattened, slender, and typically longer than the leaf blade, which causes the leaves to tremble in the wind. Mature seed catkins are about 10 cm long with hairy stalks. Seeds ripen 4-6 weeks after flowering. The bark is smooth with a waxy appearance, pale-green to white when young, becoming darker and furrowed with age. Diamond shaped markings sometimes occur.
Trembling Aspen grows in a wide variety of soils including sand and clay with dry or moist conditions. This tree species prefers upland and sheltered sites.
