They are pointed and trimmed towards the top. The base is wedge-shaped. The leaf margin is covered with curved eyelashes that are 0.4 to 0.8 millimeters long. The leaves are often reddish variegated along the edge.
It has panicles of cream-colored pointed flowers produced in spring. The loose, hemispherical inflorescence has a length of 6 to 16 centimeters (2.4 to 6.3 in) and a width of 6 to 16 centimeters 60 centimeters (24 in). The peduncle is 1 to 9 centimeters long.
