Hydrangea macrophylla 'Nikko Blue'
Nikko Blue Hydrangea commands landscape attention through prolific mophead blooms resembling oversized fluffy blue snowballs at peak flowering. This vigorous cultivar establishes rapidly, achieving approximately two feet annual growth under favorable conditions. Morning sun exposure—ideally 6 hours—paired with acidic soil conditions maximizes chromatic saturation and sustained floral production. Summer bloom initiation for the subsequent season requires thoughtful pruning protocols to preserve next year's flowering potential. Its exceptional longevity as a cut flower and refined blue coloration render it invaluable for both landscape compositions and interior floral arrangements, cementing its status as a perennial favorite among hydrangea devotees seeking reliable performance and commanding seasonal presence..
For best blue flowers make sure your soil remains acidic by top dressing you Nikko with Aluminum Sulfate every February.
