Hydrangea arborescens 'Annabelle'

Smooth Hydrangea

Mammoth snow white blooms of up to one foot in diameter last from June to September and actually get larger as the season progresses on this old fashioned, durable favorite. In fact, the blooms are so colossal that the stems may not always be up to the task of supporting them. They should be planted where they can support each other or caged.
