Each fully double, white flower head of this Lacecap Hydrangea 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 that of most varieties of Hydrangea macrophylla 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

Hydrangea is a valuable genus of some 100 species of shrubs and vines grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall -- quiet time for most woody plants -- and are worth having for that reason alone. For information on Hydrangea care, click "Growing Guide."
