Salix babylonica (Babylon Willow (var. babylonica) or Peking Willow (var. matsudana); is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the silk road to southwest Asia and Europe.[1][2]

It is a large-sized to medium deciduous tree, growing up to 20-25 m tall. It grows rapidly, but has a short lifespan. The shoots are yellowish-brown, with small buds. The leaves are spirally arranged, narrow, light green, 4-16 cm long and 0.5-2 cm broad, with finely serrate margins and long acuminate tips ; they turn a gold-yellow in autumn. The flowers are arranged in catkins produced early in the spring; it is dioecious, with the male and female catkins on separate trees.[1][3]

Cultivation

Propagation

Pests and diseases

It has also been introduced into many other areas, but has not generally been successfully cultivated outside China, being very short-lived and unsightly due to canker diseases in the more humid climates in much of Europe and North America. It is particularly susceptible to canker disease, Willow Anthracnose (Marssonina salicicola) and sensitive to late-spring frosts.[4][5]

Varieties

of var. babylonica (Babylon Willow).

  • 'Babylon' (synonym: 'Napoleon') The most widely grown cultivar with its typical weeping branches[6]
  • 'Crispa' (synonym: 'Annularis') A mutant of 'Babylon' with spirally curled leaves

of var. matsudana (Pekin Willow).

  • 'Pendula' One of the best weeping trees, with a silvery shine, hardier and more disease resistant.
  • 'Tortuosa' Upright tree with twisted and contorted branches.

Early Chinese cultivar selections include the original Weeping Willow Salix babylonica 'Pendula', in which the branches and twigs are strongly pendulous. However, most Weeping Willows outside China are hybrids between this cultivar, and either White Willow Salix alba (Salix Sepulcralis Group) or Crack Willow Salix fragilis (Salix × pendulina Wenderoth), which are better adapted to the more humid climates of most heavily populated regions of Europe and North America. The most widely grown Weeping Willow cultivar is Salix Sepulcralis Group 'Chrysocoma', with bright yellowish shoots.[4][5]
