Black Willow

Salix nigra

This species is native to eastern North America. Considered to be the largest species of North American willow, trees can grow up to 45 m in height and the trunks are covered in dark brown to black fissured bark. In 1829, the natural glucoside salicin, the basic ingredient of aspirin, was isolated from this species, although today salicylic acid is synthesized chemically rather than extracted from willows.
