The leaf edges are serrated, with large, coarse, irregular teeth, a characteristic that distinguishes the species from other willows, which have much finer serrations on their leaves. The leaves are dull blue green in color and smooth in texture when mature; new leaves are coated in downy hairs. The leaves are up to 5 inches long and 1.5 inches wide.
