Proven Winners® SUMMER WINE® Ninebark Physocarpus opulifolius 'Seward' USPP 14,821; CBR 2641
Botanical Reference: Physocarpus opulifolius
 
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.
