Pinky Winky Prime™ Hydrangea

A lot of breeding work is about introducing smaller plants, but in this case, we went big. Pinky Winky Prime is literally a bit bigger than its predecessor and it’s got a bigger personality to match! Its big lacey flowers are like lanterns in the summertime. Vibrant white panicles begin to blush up from the bottom, turning the blooms into a two-toned combo that’s impossible to miss. At the summer’s end, it sets itself apart from the original by deepening to a shade of true dark pink.

Why grow Pinky Winky Prime hydrangea?
– Massive flowers
– Interesting color change from summer into fall
– Large size works perfectly as a screen or as the specimen for an island bed

Plant Care

Light: The most sun-tolerant type of hydrangea! It will thrive in full sun to part shade. In warmer zones, it could benefit from placement in afternoon shade.

Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. Soil pH does not affect flower color, it matures to deep pink in the fall. If browning occurs instead of aging to pink, this is an indication the nights are too warm or that it is getting inconsistent water.

Water: Average water needs.

Fertilizing: Nothing special required. If desired, you may apply a granular fertilizer formulated for woody plants in late winter/early spring when the soil is workable.

Pruning: Pruning is recommended in early spring. Remove weak branches in the middle and about 1/3 of the height and width. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time, just cut back to a set of leaves!

Other: It can be used as a cut flower! For its longest vase life, cut vertically up the stem about 2″. This will help it absorb more water.
