White Willow

Salix alba

Non-native

White willow is a medium to large tree; typically growing 10-30 meters tall. It is native to Europe and western and central Asia, it gets its name from the white underside of the leaves. White willow enjoys moist sites such as streams and rivers with full sun, and often hybridize with other willow species such as the weeping willow. It is fast growing but relatively short lived, seeing as it is highly susceptible to many diseases such as the watermark disease caused by a bacteria called Brenneria salicis (staining of the wood).
