Quick Overview:

‘Diabolo’ is a purple-leaved ninebark cultivar. Like the species, it is an upright, spreading, somewhat coarse, deciduous shrub which is closely related to genus Spiraea. It typically grows 4-8′ (less frequently to 10′) tall. Small pinkish-white, five-petaled flowers in dense, flat, rounded, 1-2″ diameter, spirea-like clusters (corymbs) appear in late spring. Flowers give way to drooping clusters of reddish fruit (inflated seed capsules). Ovate to rounded, usually 3-5 lobed leaves (to 4″ long) are dark purple. Purple foliage tends to green up in hot summer climates as the summer progresses. Ninebark is named for its exfoliating bark (on mature branches) which peels in strips to reveal several layers of reddish to light brown inner bark. Bark provides winter interest but is usually hidden by the foliage during the growing season.  (Courtesy of Missouri Botanical Garden Plant Finder)


Easily grown in average, slightly acidic, dry to medium moisture, well-drained soil in full sun to part shade. Best in full sun in the northern part or its growing range, but appreciates some afternoon shade. Tolerates a wide range of soil conditions. Prune as needed immediately after bloom and no later than mid-August. Plants may be cut close to the ground in winter to rejuvenate.  (Courtesy of Missouri Botanical Garden Plant Finder)
