Bigtooth Aspen - Populus grandidentata
Widespread from the Midwest to the Northeast and parts of Canada, this aspen is less common than Quaking Aspen. It grows in sandy soils from about 600 feet to over 3,000 in the southern part of its range. The trees may reach 60 feet in height and are upright, with rigid branches. The bark is dark and the leaves have large teeth that lend a scalloped look. Autumn color is often attractive. The catkins are short and the capsules are in dense clusters. This aspen is often planted in disturbed landscapes, such as in old mine sites or burned-over lands.
