Description

The bigger the show, the better!

Huge florets give Polar Ball® panicle hydrangea a nice, full appearance. Large panicles are packed with pure white flowers that age to a soft pink. The outrageously oversized flowers are help up nicely by sturdy stems, so this plant is very showy in gardens or containers.

Soil Adaptable to most any soil except very wet or excessively alkaline soils.

Pruning In late winter or early spring, cut back by about one-third its total height, just above a set of large buds. This ensures that the growth for the season will come vigorous buds lower on the plant and also serves to remove any remaining dried blooms. Alternatively, cut back in autumn once the plant has gone completely dormant. May be cut back harder if desired, though this tends to produce stems that are unable to achieve maximum stem strength the following season.

Uses Specimen; mixed borders; mass plantings. Makes a good hedge or screen. Excellent for cut flowers, both fresh and dried.

Growing Tips Panicle hydrangeas are the most sun tolerant hydrangeas and are also resistant to wilting. In cooler climates, full sun is recommended for best stem strength and flower set. Flower color is unaffected by soil chemistry. If flowers turn brown and dry instead of aging to pink or red, this indicates that the plant needs more water or that nighttime temperatures are too high for the transition to occur.
