We selected this new ninebark because of the stunning foliage. Reddish new growth matures to deep red-purple foliage that holds its color reliably all summer, which we have witnessed in our trials in Georgia and other test sites. Add to that, Fireside® doesn’t show any signs of powdery mildew in the field or in production. The leaf size is intermediate; bigger than Little Devil™ but smaller than Diabolo®. Pinkish-white flowers bloom in spring and foliage turns deep purple in fall. The plant habit is tidier than other Physocarpus with a rounded, upright shape.
