This reliably reblooming Mountain hydrangea will flower all summer long, starting in spring on old wood and continuing on new wood throughout the balance of the growing season. The large, double florets create an arresting display of pink or blue flowers depending on soil pH. The Tuff Stuff® series deliver superior performance in colder regions and require minimal maintenance (only light pruning to remove dead wood in spring.) They grow best with some sun in moist, well-drained soils that do not dry out for long periods.
