Wedding Gown HydrangeaAlso known as 'Dancing Snow', Wedding Gown' is truly a one of a kind shade hydrangea . . . Lacecap flowers look like a small bridal bouquet with fully double larger white blooms surrounding a center packed with smaller blooms. Because plants bloom on new growth, you're assured of having flowers every year regardless of the severity of the previous winter weather. Leaves drop in winter and emerge in early spring before flowers.
