The white willow, like the crack willow, is a native tree. They share many features, but differ in that the white willow does not grow as large. The white willow grows to 16 metres; the crack willow to 27 metres. Both are native to Britain.
The more well known weeping willow is sometimes a hybrid of this tree, but not always, as their are different types.
