Description and Features

This fast-growing deciduous tree reaches 40–50 feet tall with smooth, white bark marked by black scars. Leaves are nearly round, with flattened petioles that cause them to flutter. Fall color is intense yellow. It spreads by root suckers, forming large clonal colonies.

Cultivation and Uses

Quaking aspen prefers full sun and moist, well-drained soil. It is short-lived (80–100 years) and susceptible to many pests and diseases. Used for reclamation, wildlife habitat, and pulp. In landscapes, it can be invasive due to suckering.
