I saw this on Cape Cod a few years ago and I've never seen a larger bloom. It is as big as a dinner plate on a mature plant (and super close to that on the younger plants). Great colorful lacecap blooms with similarly colored fertile florets. One petal can be up to 3" wide. The pastel color will deepen with age, too.Hydrangea macrophylla 'SMHMLDD' PP25105 | Proven Winners® Color Choice®
