Plains Cottonwood

Wyoming designated the plains cottonwood as official state tree in 1947. The plains cottonwood is a large, fast-growing, short-lived tree of the Great Plains and eastern border of the Rocky Mountains. Members of the willow family, cottonwoods are named for the cotton-like mass of hairs surrounding their seeds. They are related to poplars and aspens.
