Salix caprea (goat willow, also known as the pussy willow or great sallow) is a common species of willow native to Europe and western and central Asia. t is a deciduous shrub or small tree, reaching a height of 8–10 m (26–33 ft), rarely to 13 m. The leaves are 3–12 cm long and from 2–8 cm wide, broader than most other willows. The flowers are soft silky, and silvery 3-7-cm-long catkins are produced in early spring before the new leaves appear; the male and female catkins are on different plants (dioecious). The male catkins mature yellow at pollen release, the female catkins mature pale green. The fruit is a small capsule 5–10 mm long containing numerous minute seeds embedded in fine, cottony hairs.
