Willows are often large trees, but these are dwarf plants, found on open mountains or in damp places, and well suited for cool places in a rock garden or in other places in the garden that do not dry out. Some spread outwards, rooting as they go, and if they go beyond their planned space, lift the shoots from the end, and cut them back.

Salix hastata 'Wehrhahnii' is a lovely semi-dwarf willow, with beautiful greyish-white catkins, of course covered with yellow pollen when fully in flower, which is in late winter or early spring.
