Physocarpus Opufolius (Ninebark) 'diabolo' is easily grown in average, slightly acidic, dry to medium moisture, well-drained soil in full sun to part shade. Best in full sun. 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. This is an upright, spreading, somewhat coarse, deciduous shrub which is closely related to the genus Spiraea. In native habitat it typically occurs along streams, rocky banks, gravel bars and in moist thickets. Grows 5-7’ tall. Noted for its exfoliating bark (on mature branches) which peels in strips to reveal several layers of reddish to light brown inner bark (hence the common name of ninebark). Bark provides winter interest, but is usually hidden by the foliage during the growing season. Features small pink or white, five-petaled flowers appearing in dense, flat, rounded, 1-2” diameter clusters in late spring. Flowers give way to drooping clusters of reddish fruit. Oblong lobed leaves are dull blackish-green in summer changing to an undistinguished yellow in fall. 5 gal
Full sun only- tends to get mildew if grown in shade or part shade and won't have great color either.
