Most important are eastern cottonwood (P. del‑ toides and its varieties), also known as Carolina poplar and whitewood; swamp cottonwood (P. heterophylla), also known as river cottonwood and swamp poplar; black cottonwood (P. trichocarpa); and balsam poplar (P. balsam‑ ifera). Eastern and swamp cottonwood grow throughout the eastern half of the United States. Greatest production of lumber is in the Southern and Central States. Black cottonwood grows on the West Coast and in western Montana, northern Idaho, and western Nevada. Balsam poplar grows from Alaska across Canada and in the northern Great Lakes States.
