Populus tremuloides - Quaking Aspen


Location: Aspen Forests

Description: Aspen trees are one of the defining plants of Colorado's landscape. The are straight, tall trees with white bark. The leaves are round and frequently rustle in the wind, hence the common name "Quaking Aspen". The Aspen has some interesting characteristics, including photosynthetic bark which produces energy for the tree even during dormant times. Additionally, Aspens spread by root often forming large groves which are in fact only one tree! It was previously thought that an Aspen grove outside of Park City, Utah was the largest living organism on earth. A bed of plankton has since unseated this Aspen grove as the world's largest organism.
