Physocarpus 'Diabolo'
FamilyRosaceae
Physocarpus opulifolius ‘Diabolo’, known as Diabolo ninebark, is a deciduous ornamental shrub with a broad, dense, and vigorous habit, recognized for its dark purple, almost black foliage that maintains its intensity throughout the summer in full sun. Highly structural, it forms an imposing mass, ideal for informal hedges, screens, or in beds contrasting with light-colored foliage. In spring, corymbs of pinkish-white flowers appear, highlighting the dark foliage, followed by small, decorative dark red fruits in late summer. Its slightly exfoliating mature bark adds subtle winter interest. Physocarpus opulifolius ‘Diabolo’ tolerates a wide variety of well-drained soils and handles northern climates very well, making it a reliable, durable, and low-maintenance choice.
