Hydrangea macrophylla 'COF HM3' PP32584
Who doesn’t love the cool blue summer magic that a sweet blooming bigleaf hydrangea can bring to the landscape? People are crazy for that elusive blue color and Rock-n-Roll™ delivers that magic effortlessly. A sport that was discovered by Dr. Michael Dirr. Stiff stems feature outstanding red color and are covered with deep green foliage that forms a perfect backdrop for mophead flowers in dreamy blue to purple shades that nearly cover the plant.
Exceedingly hardy and blooming profusely on old and new wood, this re-blooming masterpiece will be the envy of the neighborhood providing a full season of color from June to October. At 5 to 6’ tall and wide, Rock-n-Roll™ can be the perfect summer-blooming specimen or can spice up any border area with its great form, foliage, and incredible flower power.
