The immensely popular 'Nikko Blue' Hydrangea macrophylla is well-deservedly renowned for its large, rounded flower heads filled with rich, deep blue florets. It blooms abundantly for up to two months in early summer and continues to produce new flower stems throughout the season. With lush, serrated, medium green foliage, it has become the benchmark for other blue hydrangeas.
