‘Ruby’ typically grows 8 to 10 ft. tall and 8 ft wide. It has large, 10 inch long conical flowerheads which contain a mixture of showy but sterile flowers and smaller, fertile but nonshowy ones. The flowers emerge white in July, and turn pink as they mature, and then a deeper pinkish red as they age. With new flowers continually emerging at the tip of the cone, the flowerheads are a lovely blend of colors, creamy white at the top melting into pink in the middle and then finally into a deep pinkish red at the base of the cone. The flowers emerge in July, and continue to bloom until fall. The color of the flowers is not affected by the pH of the soil. ‘Ruby’ does well in full sun to light shade and is moderately drought - tolerant. It blooms on new wood so the flowers are not susceptible to late spring frosts. This is a hybrid of Hydrangea paniculata which is native to Japan, China and Korea where it grows at altitudes up to 4,000 ft.
