Growing to 3 m (10 ft) tall by 5 m (16 ft) broad, it is an erect bushy deciduous shrub with narrow grey-green leaves up to 20 cm (8 in) long, which turn yellow in autumn (fall). The green catkins, 3–6 cm (1–2 in) long, appear with the leaves in spring, male catkins having yellow anthers. [5] Like all willows, the species is dioecious.
The flowers are yellow catkins, 3–8 cm (1 + 1 ⁄ 4 – 3 + 1 ⁄ 4 in) long, produced in the spring with the leaves. The reddish-yellow fruit matures in late spring or early summer, and the individual capsules are 4–6 millimetres (3 ⁄ 16 – 1 ⁄ 4 in) long.
