Physocarpus opulifolius 'Monlo'
With its upright, arching branches and dark chocolate to purple foliage, Diabolo® ninebark offers a color contrast with silver-leaved plants and makes a fine backdrop hedge. Clusters of button-like, pinkish white flowers appear in summer. Even when they fade to a tawny tone, they stand out nicely against the dark leaves. -Chris McKernan, Regional Picks: Lower Plains, Fine Gardening issue #120
