Hydrangea Paniculata ‘Phantom’ is a remarkable panicle hydrangea with the largest flower heads of any of its species. The flowers could be up to 15 inches long. The conical color-changing blooms unfold in midsummer as a creamy white, then graduate to a blushing, soft pink as the summer progresses. It is a heavy bloomer with sturdy-stemmed flowers that do not flop. It is a robust upright cultivar and produces dense, conical, rounded heads of sterile white flowers. It calls for moderate to hard pruning. The color of the flowers is not affected by the pH of the soil. Phantom blooms on the current season’s wood so it is not susceptible to late spring frosts. It does well in full sun to light shade and is moderately drought-tolerant. ‘Phantom’ is a hybrid of Hydrangea paniculata which is native to Japan, China and Korea where it grows at altitudes up to 4,000 feet.
