Crack Willow Overview

Salix fragilis is a deciduous tree species from the Salicaceae family. Originating from Turkey, it is commonly known by the names Crack Willow and Brittle Willow, amongst others. It is hardy and has a bushy habit and may form multiple trunks, easily growing to 12m in height. Leaves are bright green with finely serrated edges and measure between 9-15cm in length. Young foliage has fine hairs, which are reduced over time, tending to have a few on the underside of older leaves. The leaves appear from narrow, buds which lie close to the stems. Flowers form from late spring to early summer, after the leaves. They are arranged in catkin structures and this species is dioecious and so produces male and female flowers on different plants. The female flowers are green and the male flowers yellow. Bark is coloured dark grey-brown and has a fissured texture. Stems are flexible and yellow-brown in colour.
