Annabelle is a stunning white hydrangea, often producing heads over 10" in diameter. Unlike the better known blue and pink hydrangeas (macrophyllas), Annabelle blooms every year even after severe pruning or intensely cold winters. The huge, white "drumstick" blooms appear in profusion without fail.Some people plant 'Annabelle' as a hedge since it can be cut back severely in the winter for a tidy effect.
