Diabolo Ninebark (Physocarpus opulifolius 'Monlo') features eye-catching flowers, deep reddish purple leaves, and wonderfully textured bark. It's a real knockout plant that's also easy to grow.
Native to North America, this deciduous shrub family grows along streams, rocky banks, and in moist wooded areas. The unique burgundy red leaf of this particular variety is absolutely stunning and quite rare.
Since its introduction, more than a few people have called it 'Diablo' Ninebark, so don't be surprised if you hear it called by this name, too. The common name of "Ninebark" comes from the textured stems of the plant. They have a unique way of "exfoliating," or peeling back, to expose a variety of reddish-brown layers underneath. The look is quite ornamental, and it definitely gives your garden some Winter Interest.
The Diabolo Ninebark is prized for its four seasons of interest. In spring, white, button-like blooms appear in clusters. They present a showy display that's sure to draw attention.
Ninebark is actually related to the Spirea species, and the little white flowers will remind you of those sweet, button-shaped blooms. Mother Nature knows what she's doing. The profuse creamy white flowers are an amazing contrast to the deliciously deep red leaves.
Butterflies, hummingbirds and bees also love these flat blooms. We think they are easier to land on!
At the end of the growing season in fall, ornamental red capsules sparkle on the tips of the branches. They'll add a ton of charm to the late season landscape.
However, even though all of these features are extraordinary, it's the shiny, dark purple foliage in summer that act as this shrub's real claim to fame. These long, lobed leaves turn an elegant deep purple that's sure to stand out in almost any setting.
Ninebark is recommended on many fire safe plant lists.
