Three willow flowers appearing as catkins. Willows are deciduous trees and shrubs in the genus Salix, part of the willow family Salicaceae. Willows are dioecious with male and female catkins on different plants; the catkins are produced early in the spring, often before the leaves or as the new leaves open.
