Grey willow is a species of willow tree commonly found in wet and marshy areas. Synonyms for grey willow include the European willow, pussy willow, and Salix cinerea. The European willow is native to Europe and Asia, but has been introduced to North America as well. Pussy willows are a type of grey willow with soft, furry catkins that appear in early spring. Salix cinerea is the Latin name for the grey willow and is commonly used in scientific contexts. Regardless of the name used, the grey willow is well-known for its pliability and is often used for weaving baskets and other objects.
