Origins:Physocarpus opulifolius is a shrub native to roughly the eastern half of North America, where it grows along streams, the edges of woods and on rocky hillsides. Coppertina originated as a cross between two earlier P. opulifolius cultivars: the yellow ‘Darts Gold’ and Diabolo (‘Monlo’), which has purple leaves.
How to grow Coppertina ninebark: Site in full sun to part shade, in any soil with good drainage. Once established it can tolerate some drought. Provide a site with good air circulation to avoid powdery mildew, which can be a problem for nine barks in humid regions. Ninebark looks best with its natural shape, but if necessary it can be pruned right after it flowers. Ninebark can also be cut back hard, close to ground level, in winter to promote new growth.
