About
Salix nigra, or the black willow, is a species of willow native to a large portion of North America, from New Brunswick and southern Ontario west to Arizona and California, and south to northern Florida and Texas.
Where it grows
Salix nigra is native to a large portion of North America, from New Brunswick and southern Ontario west to California and Arizona, and south to northern Florida and Texas. It is also found in parts of Mexico, both south and west of the Rio Grande. It has also been introduced along streams in the state of Utah. Salix nigra grows best in areas of full sun and wet or moist soils. Thus, it is typically found along streams and in swamps.
Uses
Black willow roots are very bitter and have been used as a substitute for quinine in the past. Ethnobotanical uses of black willow by various Native American tribes include basketry, and treatment of fever, headache, and coughs.
