About This Plant
Hydrangea paniculata is a deciduous shrub native to China and Japan. It is known for its large, conical flower clusters that bloom in mid to late summer. The flowers start off white or greenish-white and gradually turn pink or red as they age. The leaves are dark green and have a serrated edge.
Plant Care Instructions
Outdoor Size Range
6-18 feet (1.8-5.5 m)
Light Requirements
Panicled hydrangeas prefer full sun to partial shade. In hot climates, they benefit from some afternoon shade.
Humidity Needs
Panicled hydrangeas prefer moderate to high humidity levels. They benefit from occasional misting or placing a humidifier nearby.
Fertilizing Schedule
Fertilize in the spring with a slow-release, balanced fertilizer. Avoid fertilizing in the fall, as this can stimulate new growth that may not have time to harden off before winter.
Pruning Guidelines
Prune in late winter or early spring before new growth appears. Remove any dead, damaged, or diseased wood, and cut back last year's growth to a pair of healthy buds. This will encourage bushier growth and more flowers.

Panicled hydrangeas are relatively pest and disease-free, but they can be susceptible to aphids, spider mites, and powdery mildew.
