Salix Corkscrew Willow 6-7'
"Salix matsudana (Chinese Willow) is a species of willow native to northeastern China. The species is named in honour of Sadahisa Matsudo, a Japanese botanist. Three varieties are recognized, Salix matsudana var. anshanensis, S. matsudana var. matsudana, and S. . pseudomatsudana. The species is widely cultivated in China, and a horticultural variant with twisted twigs, the corkscrew willow, is widely planted. Salix matsudana is a medium-sized to large, deciduous, upright, rapidly growing tree to 20-25 ft tall, but has a short lifespan. Salix matsudana is dioecious, with the male and female catkins on separate trees. The leaves are narrow, light green, around 4-10 cm long and 1-2 cm broad. The flowers are borne in catkins produced early in the spring"
