The Smooth Hydrangea (Hydrangea arborescens) is a native North American species known for its rounded habit and large, white flower clusters that bloom on new wood. It is exceptionally cold-hardy and thrives in partial shade. The species is the parent of popular cultivars like 'Annabelle' and 'Incrediball'. Its flowers attract pollinators and the dried flower heads provide winter interest.
