Ninebark 'Diabolo®'

Diabolo® is a variety of Ninebark that produces deep purple foliage that holds its colour all season long. In late spring, clusters of small, creamy-white to pale pink flowers appear. The leaves of Diabolo® may turn green if grown in too much shade or during hot weather. 

Ninebarks are low-maintenance and easy to grow for beginner and intermediate gardeners. They grow best in full sun to light shade, with average, well-drained soil. They're drought-tolerant once established, but like consistent moisture when young.
