Rounded deciduous shrub with large, veined leaves and large, mophead flowers. They can grow up to 2m tall and wide but tend to be kept to about half that size.
An old fashioned plant, good for that cottage garden look.
Flowers will be blue in acid soils, pink or red in alkaline soils but the white varieties stay white.
In hotter climates keep in total shade or the flowers and leaves will scorch.
