Quaking Aspen

Populous tremuloides


Quaking aspen are deciduous trees with straight trunks and gently ascending branches. Bigtooth aspen can be distinguished from quaking aspen by its leaves; they are bigger and marked with large, irregular teeth on the leaf margins. Quaking aspen is typically closer to 50 feet. Six species of aspen exist worldwide--all belonging to the scientific genus Populus. Quaking aspen and bigtooth aspen have white bark and brilliant fall color; both provide food for black bear, deer, porcupine, beaver, elk and moose. Native Americans used both of these trees as food, grinding the dried inner bark into meal for bread or mush


According to the Unites States Department of Agriculture, quaking aspen is the most widely distributed tree on the continent, its growth range extending from Alaska to eastern Canada and south to Mexico. Minnesota, Wisconsin, Michigan, Colorado and Alaska each have at least 2 million acres of quaking aspen forest. On the other hand, bigtooth aspen is found largely in the northeastern United States and southeastern Canada.

Easily my favorite deciduous tree. I love how they shimmer and "quake" in the breeze. Thanks for the great info. I knew that certain willows contained salicin but I didn't know quaking aspen did.
