Hydrangea arborescens

Smooth Hydrangea, Hills of Snow

This is a wide-ranging group of evergreens and climbing species that includes the old-fashioned, ever-popular deciduous shrub. Plant the fast-grower in a mass in partial shade or in tubs, and be sure to water heavily. Adding aluminum sulfate to make the soil more acid produces blue-tinted flowers, while adding lime creates neutral to alkaline soil which flavors pink-tinted flowers. Remove old flowers and deadwood to control shape immediately after flowering.
