Hydrangea Incrediball is an update on the classic 'Annabelle' with extra huge flower heads said to have strong enough stems to hold the flowers up even in a rain storm. We'll see about that but they sure are magnificent even if they droop a little. Smooth hydrangea is native to eastern North America and is among the hardiest in the genus.
