It is a medium-sized deciduous tree growing to 10–15 m tall, with a trunk up to 1 m diameter. The bark is pale greenish-grey and smooth on young trees with dark grey diamond-shaped lenticels, becoming dark grey and fissured on older trees.
The adult leaves, produced on branches of mature trees, are nearly round, slightly wider than long, 2–8 cm diameter, with a coarsely toothed margin and a laterally flattened petiole 4–8 cm long. The flat petiole allows them to tremble in even slight breezes, and is the source of its scientific name.
The leaves on seedlings and fast-growing stems of root sprouts are very different, heart-shaped to nearly triangular, and often much larger, up to 20 cm long; their petiole is also less flattened.
The flowers are wind-pollinated catkins produced in early spring before the new leaves appear; they are dioecious, with male and female catkins on different trees.
The male catkins are patterned green and brown, 5–10 cm long when shedding pollen; the female catkins are green, 2–4 cm long at pollination, maturing in early summer to bear 10–20 capsules each containing numerous tiny seeds embedded in downy fluff. The fluff assists wind dispersal of the seeds when the capsules split open at maturity.
It can be distinguished from the closely related North American Populus tremuloides by the leaves being more coarsely toothed.
It is a very hardy species and tolerates long, cold winters and short summers.
Like other aspens, it spreads extensively by root sprouts, which may be produced up to 40 m from the parent tree, forming extensive clonal colonies.
The hybrid with Populus alba (White Poplar), known as Grey Poplar Populus × canescens, is widely found in Europe and central Asia.
Hybrids with several other aspens have also been bred at forestry research institutes in order to find trees with greater timber production and disease resistance (e.g. P. tremula × P. tremuloides, bred in Denmark).
Aspen is resistant to browsing pressure by fallow deer due to its unpleasant taste.
Aspen wood is soft, light yet relatively strong and has been used to make paddles and oars.
Many native North American Indian tribes valued it for its antiseptic and analgesic qualities and they would use it in the treatment of wounds, skin complaints and respiratory disorders.
