Hydrangea macrophylla ‘Nikko Blue’ is one of the most popular mophead hydrangeas, prized for its spectacular large, rounded clusters of blue flowers that bloom from June to September. The intensity of the flower colour depends on the soil pH – acidic soils in Ireland bring out vibrant blues, while alkaline soils may give more pink tones. A deciduous shrub, it grows to around 1.2–1.8m tall and wide, forming a dense, bushy habit with lush, dark green leaves that provide excellent summer garden structure.

Hydrangea macrophylla ‘Nikko Blue’ is one of the most popular mophead hydrangeas, prized for its spectacular large, rounded clusters of blue flowers that bloom from June to September. The intensity of the flower colour depends on the soil pH – acidic soils in Ireland bring out vibrant blues, while alkaline soils may give more pink tones. A deciduous shrub, it grows to around 1.2–1.8m tall and wide, forming a dense, bushy habit with lush, dark green leaves that provide excellent summer garden structure.
Site: Best planted in partial shade; morning sun with afternoon shade is ideal. Avoid hot, dry sites.
Soil: Moist, well-drained soil enriched with organic matter. For strong blue flowers, aim for acidic soil (pH 5.5 or lower). Adding ericaceous compost and aluminium sulphate will help maintain colour.
Planting time: Spring or autumn, when soil is workable and moisture is reliable.
Spacing: Plant shrubs 1–1.5m apart for a full display hedge or group planting.
Mulching: Apply an organic mulch each spring to keep soil cool and moist.
Watering: Keep soil consistently moist, especially during dry Irish summers. Avoid waterlogging.
Feeding: Use a balanced, slow-release fertiliser in spring. For deeper blue flowers, apply ericaceous feed.
Pruning: Minimal pruning required. Remove dead flower heads in spring, cutting back to the first pair of healthy buds. Older stems can be thinned to encourage fresh growth.
Winter care: Hardy in Ireland, though flower buds can be damaged by late frosts. Protect young plants with fleece in exposed sites.
Pollinators: While mophead hydrangeas have fewer fertile florets than lacecap varieties, they still provide some nectar and pollen for bees and hoverflies.
Habitat: Dense foliage offers shelter for small birds and beneficial insects.
Wildlife gardening: Can be paired with native hedging or other shrubs to enhance ecological value in Irish gardens.
Perfect for Irish cottage gardens, coastal areas, and shaded town gardens.
Provides long-lasting summer colour and works well in borders, mixed beds, or large containers.
Low-maintenance, reliable, and ideal for gardeners of all skill levels.
