Hydrangea macrophylla Glam Rock ('Horwack') (PBR)
hydrangea
One of the most colourful of the new breed, this hortensia hydrangea produces impressive clusters of flowers, each of which consist of three colours. Like many hydrangeas, the flower colour will vary depending on the soil type, but primarily they are a hot pinkish red with a bluish purple eye (when grown in acidic soils) and splashes of lime green at the petal tips. If you want a showy and long-flowering shrub, then you won't be disappointed.
