The Smooth Hydrangea 'Grandiflora' (also known as 'Hills of Snow') is an old-fashioned cultivar of Hydrangea arborescens that produces large, rounded clusters of white flowers. It blooms on new wood, making it extremely cold-hardy. This cultivar has a loose, open habit and is often used in naturalized plantings or as a background shrub in shade gardens.
