DIAMANT ROUGE is a new panicle hydrangea from 2012. Bred by Jean Renault from France this hydrangea belongs to those with the richest red late summer and autumn flowers. DIAMANT ROUGE hydrangea starts blooming in midsummer, the inflorescence is oval rather than cone-shaped, composed of mainly sterile flowers which are creamy white at the beginning, turning bright pink in August, and very dark purple red in September and October. Deciduous leaves are ovate to oval, pointed, deep green and deeply veined. Stems are burgundy red. Diamant Rouge hydrangea makes an upright but not stiff shrub. Patented as Rendia under PP24667 in 2012.

It will grow in almost any soil type, preferably humus-rich, moist soil that is not too heavy or shallow. Once established it does not need extra watering like big-leaf hydrangeas. Full sun is best but it will grow in shade, too. Feeding is much recommended to enhance flower size. We recommend regular pruning every spring before the buds begin to swell. By cutting at least two thirds of previous year’s growth you will get a strong shrub with large flowers and a regular shape. It is hardy to at least -34°C (USDA zone 4).
