Populus balsamifera is a deciduous, perennial tree that can reach 30 to 80 feet in height.
It is primarily a tree of boreal and montane forests, especially in Alaska and Canada. In the U.S., it is common in the Great Lakes region and northern New England, and in parts of the Rocky Mountains (especially Colorado and Wyoming).
Balsam poplar grows mainly in riparian areas such as river floodplains, stream and lake shores, swamps, and moist conifer forests, but will tolerate drier sites.
