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.
