Bigtooth Aspen is not as common or as ornamental as its well-known brother, Quaking Aspen, but it is still a very nice ornamental tree with its nice big quaking leaves and smooth tan bark that eventually ages to a gray-brown deeply furrowed bark. 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. There are some in some spots of the sandy, acid soils of the pine barrens of southern New Jersey. I remember seeing some here and there in central MN on vacation years ago. It is found just in certain spots, not widespread all over the place as Red Oak, Boxelder, or Red Maple. It grows about 2 to 3.5 feet/year and lives about 60 or 70 years. ... read more

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.

Aspens are best in natural areas as groves. The root systems should never be distrubed as this encourages suckering. Few if any other trees can offer the visual and audible impact that an aspen can on a windy day. They are truly facinating to see and hear.
