Salix babylonica but beyond China, it has not generally been as successfully cultivated as some of its hybrid derivatives, being sensitive to late-spring frosts. In the more humid climates of much of Europe and eastern North America, it is susceptible to a canker disease, willow anthracnose ("Marssonina salicicola"), which makes infected trees very short-lived and unsightly. "Salix babylonica" (Babylon willow) has many cultivars, including: Various cultivars of "Salix matsudana" (Chinese willow) are now often included within "Salix babylonica", treated more broadly, including: Yet other weeping willow cultivars are derived from interspecific "Salix" hybrids, including "S. babylonica" in their parentage. The most widely
Salix babylonica northern Syria in 1730. 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. A similar willow species also native
