Salix matsudana (Chinese Willow) is a species of willow native to northeastern China.

The species is named in honour of Sadahisa Matsuda, a Japanese botanist.
Three varieties are recognized, Salix matsudana var. anshanensis, S. matsudana var. matsudana, and S. matsudana var. 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 20–40 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[1][2]
Chinese willow has been introduced into many areas as an ornamental tree, including Australia, Europe and North America

Salix matsudana G. Koidz. ‘Tortuosa
syn: Salix matsudana G. Koidz. f. tortuosa Rehd.
This ornamental species is often grown as curiosity being similar to Salix babylonica but with shorter leaves (less than 8 cm long) glandular serrate along margin.
This cultivar has twisted branches and leaves.


Nice photographs. I think you clicked this species from US.


No … I clicked this one on 19th May, 2012 when I visited Kashmir University Botanical Garden. You can compare the date with Salix wallichiana photographs from the same garden same day. 


Thanks, …, for the wonderful post.
As per The Plant List, Salix matsudana Koidz.is a synonym of Salix babylonica L. based on WCSP (in review) .
However, Flora of China, recognises it as a separate species with a note that A. K. Skvortsov believes that this species may be synonymous with Salix babylonica.


Thanks … for detail scrutiny of its nomenclature. You information are valid. But the basic difference between the two is that S. matsudana has two glands in each female flower, whereas S. babylonica has only one. Number of gland is an important feature for the genus Salix.

Salix matsudana ‘Tortuosa’
The photographs represent two medium sized female plants. A popular cultivar similar to S. babylonica, also known as the “Corkscrew willow“.
Medium to large-sized tree, the branches and twigs grow in a spiral fashion; leaves lanceolate to linear lanceolate, bright green. Catkins small, arise with the leaves.

As a result of the ornamental shape of the branches and twigs, this cultivar is commonly used as a bonsai plant and for floral arrangements.
