Salix Alba (white willow) is a species of willow native to Europe and western and central Asia. The name derive from the white tone to underside of the leaves. It is a medium-sized to large deciduous tree growing up to 10-30 m tall. The bark is grey-brown, and deeply fissured in older trees. The shoots in the typical species are grey-brown to green-brown.
