Description

Mildew-resistant. Award-winning Summer Wine® ninebark combines the fine texture and compact branching of P. 'Nana' with the dark foliage of Diabolo®. In late spring, white button-like flowers accent the deep purple foliage nicely. In trials at Longwood Gardens, it was determined to have the best mildew resistance of all dark-leaf ninebarks. With its graceful, arching habit and landscape-friendly size, it's an easy way to add color and vibrance, especially in spring. Its color, vigor, and disease resistance makes it an excellent choice for cut flower growers looking for reliable foliage filler.

Growing Tips Though physocarpus can grow in part shade, flowering, foliage color, and disease resistance is best with a minimum of six hours of sun. Physocarpus is amenable to pruning and recovers from it quickly; however, frequent cutting back may cause the plant to develop an odd habit.
