Mallow Ninebark
Physocarpus malvaceus
Mallow ninebark is a western ninebark with maple-like leaves, white-pink flower clusters, and shredding bark for winter interest. Drought-tolerant and quick to colonize dry slopes for erosion control. Contains cyanogenic glycosides; traditionally used as an emetic (to induce vomiting), not as food.
