One of the loveliest hydrangeas, this has huge globes of tightly packed, creamy white bracts that look like giant snowballs in late summer. As autumn progresses, the blowsy flowerheads fade to pale lime and the dark green, pointed leaves turn soft yellow. It has an upright habit and makes a breathtaking feature in a wide, partly shady border, particularly when planted in groups or with other hydrangeas. The flowerheads are a popular choice for dried flower arrangements.
