Description

Everything you love about the original and more: Pinky Winky Prime® hydrangea impresses with bigger, fuller blooms that age to a far richer pink. The large, pointed panicles emerge pure white and then gradually transform to a saturated hot pink starting from the bottom and moving to the tip. Like the original, Pinky Winky Prime hydrangea is the work of Dr. Johan Van Huylenbroeck at the ILVO breeding station in Flanders.

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.
