The smooth hydrangea (Hydrangea arborescens) is a widely grown landscape shrub, and 'Annabelle', with its snowball-shaped flowers, has been the variety of choice for years. A newly discovered selection of this species has been found in Alabama that produces flowers with a unique shape that's sure to impress hydrangea lovers.
The 'Hayes Starburst' hydrangea (H. arborescens radiata) has dome-shaped, white flowers that open in a traditional lace-cap shape. Then after a few days the flowers become double, giving the blossoms a star-like effect. The flowering continues for several weeks. 'Hayes Starburst' grows 3 to 4 feet tall and wide in a range of well-drained soils, and is hardy in USDA zones 4 to 9.
