Populus trichocarpa, the black cottonwood, western balsam-poplar or California poplar, is a deciduous broadleaf tree species native to western North America. It is used for timber, and is notable as a model organism in plant biology. The tree is notable for the seed-carrying cottony fluff it releases into the air each spring.

Populus trichocarpa in the context of Populus
Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (/ˈpɒplər/ ), aspen, and cottonwood.
The western balsam poplar (P. trichocarpa) was the first tree to have its full DNA code determined by DNA sequencing, in 2006.

The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae sensu stricto) includes the willows and poplars. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the tropical Scyphostegiaceae and many of the former Flacourtiaceae.
In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera, Salix, Populus, and Chosenia (now a synonym of Salix). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales.
