Physocarpus opulifolius 'Red Baron', also known as the ‘Red Baron’ Ninebark, is a highly esteemed deciduous ornamental shrub celebrated for its intense purplish-red foliage and exceptional hardiness in the garden. This variety forms a dense, rounded bush that is perfectly suited for informal hedges, shrub borders, and structured flowerbeds. In spring, young leaves emerge in bright red tones, which then deepen to a rich purple throughout the season. This vibrant foliage creates a striking contrast with the rosy-white flowers that appear in early summer in small, rounded corymbs, attracting pollinators. After flowering, small decorative reddish fruits extend the plant’s visual appeal. Very hardy and easy to cultivate, this Ninebark tolerates ordinary soils, moderate drought, and urban conditions well.
