Quaking aspen is a tall, fast growing tree, usually 20–25 m (65–80 ft) at maturity, with a trunk 20 to 80 cm (8 inches to 2 feet 7 inches) in diameter; records are 36.5 m (119 ft 9 in) in height and 1.37 m (4 ft 6 in) in diameter.
The bark is relatively smooth, colored greenish-white to gray, and is marked by thick black horizontal scars and prominent black knots. Parallel vertical scars are tell-tale signs of elk, which strip off aspen bark with their front teeth.
The leaves on mature trees are nearly round, 4–8 centimeters (1 1⁄2–3 1⁄4 inches) in diameter with small rounded teeth, and a 3–7-centimeter (1 1⁄4–2 3⁄4-inch) long, flattened petiole.
Aspens are dioecious, with separate male and female clones. The flowers are catkins 4–6 centimeters (1 1⁄2–2 1⁄4 in) long, produced in early spring before the leaves.
The fruit is a 10-centimeter-long (4-inch) pendulous string of 6-millimeter (1⁄4-inch) capsules, each capsule containing about ten minute seeds embedded in cottony fluff, which aids wind dispersal of the seeds when they are mature in early summer.
Trees as young as 2-3 years old may begin seed production, but significant output begins starting at 10 years of age.
