The Quaking Aspen is a medium-sized deciduous tree famous for its striking white bark and leaves that flutter audibly in the wind.

Native Range
Widely distributed across North America, from Alaska across Canada down to northern Mexico, making it the most widely distributed tree species on the continent.
