Hydrangea paniculata 'Phantom' - Huge rounded panicles and lots of them on a globe-shaped to upright mounded shrub with an extended bloom period. Pure white clouds of flowers of mostly sterile florets can begin the season as early as late June / July and shade to rose pink in September and October. It's wonderful. Flower heads eventually turn brown and tend to remain on the shrub through the winter providing modest interest during the coldest part of the year. And after extensive trials RHS deems 'Phantom' a better option over 'Grandiflora'. As this plant flowers on new wood you may prune down in late winter before new growth emerges. The possibility exists that with an annual pruning you will achieve even more numerous flower heads than one left to its own devices... but even if left alone this shrub will delight. Part to full sun in fertile soil that holds onto some moisture between rains. The species hales from China; 'Phantom' is, of course, of garden origin. Hydrangea paniculata in all of its renditions flowers on new wood and can be pruned in late winter if and when necessary. Established, potted cutting grown shrub.
