'Nikko Blue' is a classic Hydrangea with flowers ranging in colour from rich, sky blue through lavender to lavender pink, depending on the pH of the soil. Plants are 4-6 feet tall and wide and bloom on old wood. In acidic soils this is one of the most beautiful blues you can grow. In less acidic soils plants can produce a multi-colour display of blue, lavender and pink all on the same plant all at the same time.
