Culture

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 of its growing range, but appreciates some afternoon shade in the St. Louis area. Tolerates a wide range of soil conditions. Prune as needed immediately after bloom and no later than mid-August. COPPERTINA is less apt to spread by suckering than the species. Plants may be cut close to the ground in winter to rejuvenate.

Noteworthy Characteristics

COPPERTINA is a patented ninebark cultivar that is most noted for its dramatic copper foliage that turns red by summer and its free-branching, mounding, compact growth habit. It is the result of a cross between P. opulifolius ‘Darts Gold’ (seed parent) and P. opulifolius ‘Monlo’ (pollen parent). It is a deciduous shrub that typically grows to 6-8’ tall and as wide, but retains compact form. Small pinkish-white, five-petaled flowers in dense, flat, rounded, 1-2” diameter, spiraea-like clusters (corymbs) appear in late spring. Serrated, ovate to rounded, 3-lobed leaves (to 3” long) emerge orange-copper in spring, but mature to a rich red by summer. 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 often hidden by the foliage during the growing season. U.S. Plant Patent PP16,371 issued March 21, 2006.
