From the "Encyclopedia of Hydrangeas," (Van Gelderen -2004), " a slow-growing shrub, about 3' high. Very free-flowering. the corymbs are flattened and usually dark lilac-red to wine red. The color does not fade. It is very difficult to get this cultivar to produce flowers that are a good blue color. the branches are very dark, resembling the color of eggplant. It is drought tolerant." No hardiness zone noted.
