Salix alba (white willow) is a species of willow native to Europe and western and central Asia. The name derives from the white tone to the undersides of the leaves.
It is a medium-sized to large deciduous tree growing up to 10–30 m tall, with a trunk up to 1 m diameter and an irregular, often-leaning crown. It is predominantly grown in Central and Southern Europe and Northern America.
White willows are fast-growing, but relatively short-lived, being susceptible to several diseases.
