Common quaking aspen characteristics are the trembling leaves and the white bark. Quaking aspens grow upright from 20-100 ft. tall with trunks 4-36 in. in diameter. The alternating, deciduous leaves are rounded and heartshaped with small grooves or teeth on the edges. The leaves rangin from 1.5-3 in. in length, [http://www.northern.edu/natsource/TREESA1/Quacki1.htm] and tend to be dark-green ontop and lighter green beneath. In the fall, they turn yellow, orange, gold, or red. [http://www.rook.org/earl/bwca/nature/trees/populustrem.html] The leaf petiole is flattened and extends all the way to the tip of the leaf, allowing it to flutter or "quake" in the wind.

The slender stems are reddish-brown, but gray over the years. The branches grow up and out, creating a crowned top. The characteristic bark of a quaking aspen is a smooth, creamy white or pale green that becomes thick and lined as the tree ages. It can become 1-2 in. deep on older trees. The roots are widespread and numerous, some reaching as far as 100 ft. away and others deeper than 5 ft. [http://www.rook.org/earl/bwca/nature/trees/populustrem.html] Flowers are dioecious (having male and female flowers on different plants of the same species) [http://encarta.msn.com/dictionary_1861604802/dioecious.html] and contained in catkins (a long hanging furry cluster of tiny leaves and flowers without petals) [http://encarta.msn.com/dictionary_/catkins.html] 1-3 in. long. The seeds have long seed hairs attached to light and pear-shaped capsules. The fruits are two-valved brown or light-green pods.
