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. Adding aluminum sulfate lowers the PH and adding lime raises the PH. Nikko has a naturally rounded growth habit, and produces a lot of stems reach up to 6 feet tall and wide. Hardy in USDA zones 6 to 9.
