Originating from China.
A titanic Hydrangea in every way. Large exotic foliage and even larger lacecap flowers make this recent introduction a must-have for woodland and dappled sun areas in jungle gardens. It eventually forms a multi-stemmed shrub bearing broad, oval, bright green leaves with long, intense blood red leaf stems and veining.
Its flowers have a dark purple central corymb surrounded by stunning pure white ray florets with beautifully serrated margins, extending some distance beyond it, making for a huge overall size of uniquely structured flower.
Vigorous and easy to grow if given sheltered woodland conditions and non alkaline soil, Hydrangeas can be slow to establish, especially in heavy clay soil, but once their roots are well established they are capable of rapid growth and greater resilience in hot and dry weather.
Height and spread after 2 – 3 years 1m x 1m
