Hydrangea arborescens 'Annabelle' This is a very hardy hydrangea that starts out green, turns white and then goes back to green. Cut it back to the ground in late fall for the largest flowers the next year. A keeper!
Annabelle hydrangea is one of the easiest types of white flowers to grow. It blooms in midsummer producing large, pure white clusters that are perfect for cutting! http://www.bhg.com/gardening/design/color/white-flower-garden-ideas/?socsrc=bhgpin031415annabellehydrangea&page=3
