Nikko Blue Hydrangea is a traditional mop-head variety that sports flowers on 'old wood' or un-pruned stems that have not died back due to winter damage. The color of the flower is dependent on the acidity or PH of the soil. The lower the PH or more acidic, the more blue the flower color will be. The higher the PH or more alkaline, will determine how pink the flower will be. Clusters of flowers appear on the ends of the stems starting in late spring, and can bloom throughout the summer.
