Additional Information

The Annabelle Smooth Hydrangea is a very popular cultivar that produces large (much larger than the straight species), upright globular heads of sterile, white flowers in June. Tops usually die back in extreme Northern regions of its hardiness zone (including Zones 4 and 5). However, flowers are on new wood, and they still appear when tops are winter killed, or plants are pruned to ground. Winter killed branches need removal. Not drought tolerant. Poor, coarse form in the winter landscape. Many feel that the dried flower heads are unattractive left on the plant.
