Growing Hydrangeas in Full Sun: Best Varieties and Watering Needs

Best Full-Sun Hydrangea

Pee Gee Hydrangea (Hydrangea paniculata 'Grandiflora') thrives in full sun. It's often trained as a small tree with white flowers that age to pink. New varieties like 'Limelight' and 'Pinky Winky' are also excellent.

Mophead Hydrangeas (H. macrophylla) in Sun

Blue/pink mopheads can grow in full sun only if kept constantly moist—daily watering in 90°F heat. They prefer morning sun and afternoon shade; flowers last longer and stay blue in part shade. In full sun, blooms brown quickly.

Recommendation

For a sunny South Carolina yard, plant Pee Gee or its cultivars. Reserve mopheads for a shadier spot.
