A real innovation! This new hydrangea, found by Jean Renault, is exceptional because of its abundant and long-life flowers. It is the paniculata with the reddest flowers! At the beginning of July this Diamond Rouge is covered with large full flowers (up to 30-40 cm). The flowers open white. Then the diamonds colour pink. Around August they turn into a spectacular radiant purple/red. Height is 1.5m and width 1.20m. Diamond Rouge prefer humus rich soil. In the full sun/semi shade and pruning at the end of the winter.
Hydrangea paniculata prefers a sunny or semi-shaded position, with shelter from cold, drying winds. Grow hydrangea plants in any non-alkaline, fertile, moist soil. Improve the soil prior to planting by adding with plenty of well rotted manure or garden compost, ensuring that it is mixed in thoroughly and deeply.
