Habitat: Moist, fertile, sandy uplands.
Leaves
Alternate, generally oval, 3 to 4 inches long, with large blunt teeth; green above and paler below; leaf stalk flattened.
Flowers
On hanging, 2- to 3-inch, fuzzy catkins, appearing before the leaves; males and females on separate trees.

Values and Uses
Although seldom harvested in Virginia, the wood can be used for paper pulp, particle board, structural panels, pallets, boxes and pelletized fuel. Aspens are a primary food source for ruffed grouse, which eat the catkins and buds. Deer and beavers also feed on aspen. Aspens are a pioneer species, stabilizing soil on disturbed sites.
Did You Know?
Despite the high production of seed, seedlings do not commonly occur in nature. Instead, suckering or sprouting from the roots, is the most common mode of reproduction. Aspen quickly colonizes disturbed sites, sometimes resulting in large, pure stands. Quaking aspen (Populus tremuloides), a related species, is rare in Virginia, but common farther north and west. It grows in large stands and has finely toothed leaves, which turn a beautiful clear yellow in fall.
