Hydrangeaceae
Hydrangea macrophylla 'Nikko Blue' is an iconic shrubby hydrangea, recognized for its abundant flowering of intense blue when grown in acidic soil. This classic variety features large, very full spherical inflorescences on a vigorous shrub with a rounded, balanced habit. Its growth is harmonious, both in height and width, making it an excellent choice for light shade borders, low flowering hedges, and isolated plantings. The deciduous, large, and lush dark green foliage creates a striking contrast with the spectacular summer blooms. 'Nikko Blue' flowers mainly on the previous year's wood, which makes winter protection of the buds important in cold climates. Highly valued for its strong visual impact and versatile use in the garden, it remains a safe bet among macrophylla hydrangeas.
