The flowers are arranged in sitting or up to 5 millimeters long stalked, 2 to 3 centimeters long catkins. Two hairy stamens are formed at the base of each individual flower. The ovary is stalked and densely hairy with a distinct stylus and divided stigma. The bracts are small, hairy white, light at the base, and dark brown to black and long bearded towards the tip. The catkins appear from April and May just before or with the leaves.
