The toughest, most cold-hardy, and most sun-tolerant of the common hydrangeas, grown for big cone-shaped (panicle) flower clusters that open creamy white in mid to late summer and age to pink, rose, or tawny tan as the season cools. Because it blooms on new wood, it flowers reliably even after hard winters and can be pruned hard in late winter without losing the show. Native to eastern and southern China, Japan, Sakhalin, and the Kuril Islands, the species is large — an arching, multi-stemmed, often vase-shaped shrub that can reach the size of a small tree — though most garden cultivars are bred smaller. It wants full sun to part shade and consistent moisture; all parts are toxic if eaten.
