distribution_en:

description_en: Genus of approximately 300 species of normally dioecious, deciduous trees and shrubs found in habitats ranging from lowland meadows and riverbanks to sand dunes and mountain screes world-wide, except in Australia. They have simple, entire or toothed, usually alternate leaves, and bear very small flowers in usually erect catkins, before or with the foliage. Of diverse form, willows are cultivated for their habit (particularly the weeping willows), catkins (of which the males are usually the most striking), foliage, and some-times coloured winter shoots. The largest willows are suitable only for a garden of large proportions; those with a weeping habit are especially effective by water. Grow smaller willows as specimen trees in a small garden, shrubby willows in a shrub border, and dwarf willows in a rock garden or trough.
