Arborescens. Incrediball is an improved upon Annabelle. Huge, creamy white blooms that turn to a light pink later on in the season. 5 feet tall and wide after time. Each bloom is much larger than Annabelle. Lightly fragrant. It makes a nice hedge, a woodland edger, or becomes an attention-getter if added to the front or back of a split rail fence with perennial plantings in the front. Give each plant space and do not be afraid to trim them back after fall frosts. No mail order on hydrangeas. Photos courtesy of Spring Meadows/Proven Winners.
