Author 'Nicoledesplat' (Id 196554 ) : This 'Hydrangea Serrata Cap Sizun is a variety of hydrangea remontant (1. 20 to 1. 40m) and one of the first hydrangea the earliest in flowering.
Good hardiness, these inflorescences vary from pale blue to pale purple, these flowers are very cut out, this is what I prefer on this one.
Hydrangea Serrata Cap Sizun flowers from June to October. (Photo Courson).
