Summer Wine Ninebark. When first being introduced to the Physocarpus cultivars I wasn't expecting something that would perform very well in the heat of the Deep South. But to my surprise they have done admirably well. This selection is more compact and has deep burgundy red foliage. As the summer progresses, the color isn't quite as intense, but it has beautiful soft pink flower clusters which line its arching stems. Grow in full sun to part shade.
