A classic mophead hydrangea, it brings a splash of striking colour to borders, containers, or mixed planting schemes. Perfect for adding drama to any garden, it thrives in moist, well-drained acidic soil soil and delivers interest throughout the growing season. Hydrangeas can change colour depending on the acidity of the soil, to keep your hydrangea blue, plant in acidic (ericaceous) compost.
