Willows, in general, are shrubs and trees belonging to the genus Salix. They are primarily native to north temperate regions and are valued for various purposes, including ornamental use, shade, erosion control, and timber. Certain willow species are also the source of salicin, a compound used in pain relievers. Willow trees typically have alternate, narrow leaves and produce catkins, with male and female flowers on separate trees.2
