Diabolo STD is grafted high and 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).
