With Hydrangea macrophylla 'Endless Summer® Dreamcloud®', you get a classic bigleaf hydrangea look in a tidy, landscape-friendly size. This cultivar is prized for its bright white, mophead-style blooms and its tendency to flower repeatedly through the growing season when conditions are right. At maturity, expect a rounded shrub about 36-48 inches tall with a similar spread, making it easy to fit into foundation plantings, mixed borders, or a focal spot near a path.
Give your plant a site with morning sun and protection from intense afternoon heat, especially in warmer zones. Full sun can work in cooler climates, but part shade is often ideal for keeping foliage fresh and blooms longer lasting. Keep the soil evenly moist but not soggy; hydrangeas perform best in fertile, well-drained soil enriched with organic matter. A layer of mulch helps conserve moisture and moderates soil temperature.
Pruning is simple: remove only dead or winter-damaged stems in early spring after you see new growth, and deadhead spent blooms if desired for a neater look. Because bigleaf hydrangeas can set buds on older wood, avoid hard pruning that removes healthy stems. In colder areas, leaving stems intact and providing some winter protection can help you get earlier, heavier flowering. Water during dry spells, and your shrub will reward you with a long season of clean white color.
