Nikko Blue Hydrangea is the iconic, time-tested classic that defines the traditional blue mophead hydrangea for generations. It is renowned for producing exceptionally large, rounded clusters of vivid blue flowers in acidic soils, creating a breathtaking display in late spring to early summer. While it blooms primarily on old wood, its unparalleled flower size and intensity of color in the right conditions have secured its place as a beloved garden treasure. For many, it remains the standard against which all other blue hydrangeas are measured.

• Iconic, True Blue Color: Famous for its large, vibrant sky-blue to sapphire-blue mophead flowers when grown in properly acidified soil. In alkaline soil, flowers are a pleasing pink.

• Exceptionally Large Flower Heads: Produces some of the largest and most impressive flower clusters of any traditional mophead hydrangea.

• Classic Landscape Presence: Matures into a robust, rounded shrub (4-6 ft tall and wide), perfect for creating a classic cottage garden look or as a lush foundation planting.

• Primary Bloom on Old Wood: Its spectacular main flush of flowers develops on buds set the previous year, requiring careful siting to protect from late frosts.

• Long-Lasting Cut Flowers: The strong-stemmed, giant blue blooms are outstanding for fresh-cut arrangements and can also be dried for winter décor.
