Hydrangea macrophylla 'Wedding Gown'
 
Each fully double, white flower head of this Hydrangea macrophylla ('Wedding Gown') is like a mini bridal bouquet, with an outer ring of large, double flowers surrounding a center packed with smaller, double ones. Flowering begins earlier than other varieties, and continues on new growth into fall if spent blooms are removed regularly. 'Wedding Gown' is hardy, stays compact, and prefers light shade. Also known as ‘Dancing Snow.’ PP 21,052
