These plants are all females, readily propagated vegetatively, and capable of hybridizing with various other kinds of willows, but not breeding true from seed. This type of tree is grown very easily through plant propagation. Two cultivated hybrids between pendulous "Salix babylonica" and other species of "Salix" willows also have pendulous branchlets, and are more commonly planted than "S. babylonica" itself: Cultivars derived from either of these hybrids are generally better adapted than "S. babylonica" to the more humid climates of most heavily populated regions of Europe and North America.
