Harlequin Bigleaf Hydrangea
Hydrangea macrophylla 'Harlequin'
Synonyms: 'Sensation 75', ‘Buttons 'n Bows’
It was a pleasant surprise to find this Hydrangea blooming in the back of a perennial border I signed up to take care of this year. Until it bloomed it had the appearance of a regular type although, upon reflection, it was growing a little thin and wispy. Since the flowers are a strong pink the garden must have alkaline soil. Like most French Hydrangeas if the soil is acid the flowers turn blue. This plant is certainly a bit of a novelty but can stand on its own. A 1967 German introduction Harlequin reaches about 36 inches tall, which is a little more compact than most macrophylla Hydrangea. It blooms on one year old wood so be careful when you prune it.
