The masses of vibrant red flowers will be a standout feature in any garden from early-summer to early-autumn. The rich red blooms produce between six and eight broad, overlapping tepals. The vibrant red is most intense along the bars, merging to a velvety, slightly purple-red at the undulating margins as they taper to blunt tips. The stamens have white filaments and dark red-wine anthers.
