Bigtooth Aspen is not as common or quite as ornamental as its well-known sister, Quaking Aspen, but it is still a very nice ornamental tree with its nice big quaking leaves and smooth creamy to gray-tan bark that eventually ages to a gray-brown deeply furrowed bark on the lower trunks. Its native range is in southeastern Canada down to Virginia-Kentucky-Tennessee up to eastern Iowa and around the Great Lakes. I first saw it growing in the alkaline dolomitic limestone soil, uphill from the east bank of the Fox River in Batavia, IL. I have seen some at the east entrance of French Creek State Park near Birdsboro, PA and in a few spots near Downingtown, in southeast PA.

A great native aspen that is very useful in natural areas, and naturalistic landscapes. Native to the northeastern United States and Southeastern Canada and as far south as eastern TN, and NC in the Mountains.
