The American big-tooth aspen (Populus grandidentata) is a tree native to North America, known for its coarse-toothed leaves and soft wood. It is also referred to as the large-toothed aspen. Aspens, in general, are trees of the genus Populus that grow farther north and at higher elevations than other Populus species. They are characterized by smooth, gray-green bark, random branching, and leaves that turn brilliant yellow in the fall. The big-tooth aspen can reach a height of up to 18 meters (59 feet) and has larger, somewhat rounded, coarse-toothed leaves compared to other aspen species.123
