Physocarpus opulifolius 'Monlo' goes by the common name of Diablo® eastern ninebark. it has attractive characteristics in all four seasons. Burgundy foliage in spring and summer is the perfect backdrop for the blush-white flowers that turn into red berries in late summer and early fall. The early frosts of fall bring out reddish tints in the leaves, and in winter, after the leaves have dropped, the attractive exfoliating bark on the main trunk is revealed. Monlo grows to a height and width of about eight to ten feet.
