"The Hydrangea White Dome, 'Hydrangea arborescens 'White Dome', a Proven Winners selection, is a hardy strong growing hydrangea that produce clouds of big, lacey, white blooms. The dome shaped flowers are held on long stems that are strong enough not to droop, even after a heavy rain. White Dome is useful as a mass planting or placed in a woodland setting. This plant produces flowers on new wood, so even if frost kills back the plant, it will still produce summer flowers. They are great for cut flowers."
