Shade hydrangeas prefer moist soil and regular watering during the growing season. For most, in order to obtain the blue flower color, apply 2 tablespoons of aluminum sulfate near the base of the plant. A rusty nail or coffee grounds will also increase the acidity of the soil which makes the flowers turn blue. Wedding Gown will not need this application as it's flowers are always white.
Double Delights™ Wedding Gown Hydrangea
Hydrangea macrophylla 'Dancing Snow' PP #21,052
Double blooms on notably strong stems grace the Double Delights™ Wedding Gown Hydrangea as well as a strong round habit with lush dark green foliage. A repeat bloomer, spring through fall. Each flower cluster transforms into an exquisite, pristine white bridal bouquet as a stunning outer ring of large blooms first unfolds, followed by lovely smaller inner blooms.
