A 35-50 ft. deciduous tree, quaking aspen is pyramidal when young, usually developing a long trunk and narrow, rounded crown at maturity. Its small, nearly round, shiny leaves have a flattened petiole which allows them to quiver in the slightest breeze. Smooth, whitish-green bark becomes furrowed at the trunk’s base with age. Silvery catkins appear before leaves. Fall color is bright yellow.
The names refer to the leaves, which in the slightest breeze tremble on their flattened leafstalks. The soft smooth bark is sometimes marked by bear claws. A pioneer tree after fires and logging and on abandoned fields, it is short-lived and replaced by conifers. Sometimes planted as an ornamental. Principal uses of the wood include pulpwood, boxes, furniture parts, matches, excelsior, and particle-board. The twigs and foliage are browsed by deer, elk, and moose, also by sheep and goats. Beavers, rabbits, and other mammals eat the bark, foliage, and buds, and grouse and quail feed on the winter buds.

Conditions Comments: Quaking aspen reproduces rapidly from seed and root suckers. It is short-lived and plagued by disease and insect problems, but is practically indifferent to soil conditions. In any soil, weeding around the tree can boost its growth surprisingly. Aspen can be grown in a clump by periodically removing the older, damaged stems, allowing new sprouts to fill in. Western material is often referred to as var. aurea.
