White willow (Salix alba) is a fast-growing deciduous tree of wet ground, typically found beside rivers, lakes and ponds, and grown as a timber, basketry and ornamental tree. It needs moist or waterlogged soil and full sun to thrive.

About
Salix alba, the 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.
How to grow it
The wood is tough, strong, and light in weight, but has minimal resistance to decay. The stems (withies) from coppiced and pollarded plants are used for basket-making. Charcoal made from the wood was important for gunpowder manufacture. The bark tannin was used in the past for tanning leather. The wood is used to make cricket bats.
S. alba wood has a low density and a lower transverse compressive strength. This allows the wood to bend, which is why it can be used to make baskets. Willow bark contains indole-3-butyric acid, which is a plant hormone stimulating root growth; willow trimmings are sometimes used to clone rootstock in place of commercial synthetic root stimulator.
Where it grows
Like all willows, Salix alba is usually to be found in wet or poorly-drained soil at the edge of pools, lakes or rivers. Its wide-spreading roots take up moisture from a large surrounding area.
