Hydrangea arborescens ‘Annabelle’, commonly known as Annabelle Hydrangea, is a beloved smooth hydrangea native to the eastern United States, admired for its enormous, rounded clusters of pure white flowers that appear from early to mid-summer. This deciduous shrub typically grows 3 to 5 feet tall and wide with a rounded habit and lush green foliage. The massive blooms can reach up to 12 inches across and often continue blooming into early fall. ‘Annabelle’ thrives in part shade and is ideal for woodland gardens, foundation plantings, and informal borders.
