This improved ninebark has an upright spreading habit and fine textured, dark foliage that sets it apart from other ninebark. It is also mildew resistant and low maintenance as it needs little to no pruning and is free from pest and disease issues and adapts to wet or dry soil. Clusters of small purplish-white flowers in June contrast nicely with the burgundy foliage. Little Devil is a good substitute for barberry in areas of the country where barberry may be invasive. Growth habit – 3-4′ high and wide, full sun to part shade.
