One of the most winter hardy of all bigleaf hydrangeas! These handsome, compact shrubs are covered with big blooms of deep blue with a long bloom period from midsummer to frost. You get flowers every year because blooms form on the current season's growth. Harsh winters are not a problem. Great foundation planting or hedge. For bluer flowers make sure your soil is on the acidic side, or enjoy the pinker blooms that result in more alkaline soil. Grows 3-4' tall and wide in full sun to full shade. Potted.
