Bigtooth Aspen

Populus grandidentata

Summary 6

Populus grandidentata, commonly called large-tooth aspen, big-tooth aspen, American aspen, or white poplar, is a deciduous tree native to eastern North America. Its range extends from Virginia north to Maine and Cape Breton Island, Nova Scotia; west to southeastern Manitoba and Minnesota; south through Iowa to extreme northeastern Missouri; and east through Illinois, Indiana, Ohio, and West Virginia.

Bigtooth aspens are dioecious, medium-sized deciduous trees with straight trunks and gently ascending branches. Heights at maturity are around 60–80 feet with diameters of 8–10 inches. Leaves are similar to Populus tremuloides, but slightly larger and having larger teeth. The leaves tremble in the wind as those of P. tremuloides do. Bark of younger trees is olive-green, thin and smooth; after 30–40 years, the bark is gray, thick and rough with grooves.

P. grandidenta are fast growing and are relatively short-lived; stands will begin to deteriorate after 60–70 years, while individuals can live up to 100 years. They often constitute early successional species of their landscapes.
