Salix discolor is a dioecious species (male and female catkins appearing on separate trees) that is most often a large multi-stemmed shrub 6-15’ tall, or as a small tree that can grow to 30’ tall. Before the foliage emerges in late winter, male trees produce a showy display of grey silky catkins (1-1.5” long) covered in yellow pollen that bees love! (Female trees produce smaller greenish catkins). They have a dull medium green color elliptic leave with a bluish grey underneath side (to 5” long) with marginal teeth. Fall color is usually a greenish-yellow. Can be weeping or upright.
