Incrediball Hydrangea
Hydrangea arborescens ‘Abetwo’ · a white smooth hydrangea
An improved Annabelle with enormous white flower heads on sturdy stems that don't flop, aging to green through fall. It blooms on new wood, so even a winter that kills it to the ground doesn't cost the flowers. Give it full sun in the North, afternoon shade where summers are hot, and cool, moist soil.
