Think of Puffer Fish™ as a larger, more puffed up Bobo®, with fluffy white blooms that engulf the entire plant, nearly obscuring the foliage. The flowers open and mature to a pure white. As the blooms age, they turn lime green and, for a bit of surprise, a fresh sprig of white flowers emerges from the tip of the panicle. A tight, compact habit with stems strong enough to hold its blooms, this NCSU hydrangea has all the talent needed to be a first-class landscape performer. As with most Hydrangeas, morning sun and afternoon shade is best. That being said, if watered well throughout the dry season, grouped plantings of panicle hydrangeas in full sun can be spectacular! Grows up to 6' tall and wide. Hardy to Zone 3.
