Pussy willow is a narrow shrub or small tree to 20 ft. with multiple trunks and dark-gray, scaly bark. The familiar, silvery-gray, furry catkins appear before leaf emergence. Deciduous leaves are broad, bright-green and shiny. Many-stemmed shrub or small tree with open rounded crown; silky, furry catkins appear in late winter and early spring.
The large flower buds burst and expose their soft silky hair, or pussy fur, early in the year. In winter, cut Pussy Willow twigs can be put in water and the flowers forced at warm temperatures. Some twigs will produce beautiful golden stamens, while others will bear slender greenish pistils. The Latin species name refers to the contrasting colors of the leaf surfaces, which aid in recognition. Pussy willow catkins are the first willow catkins to appear each year and are recognized as a sign of spring. (Kershaw)
