Understanding the Context

Ninebark (Physocarpus opulifolius) is a deciduous shrub native to eastern North America, known for its distinctive, peeling bark that gives it its common name, appearing as if it has several layers or ‘nine barks’. Glowing gold or amber, dusky purple or emerald green, Physocarpus offers a rainbow of foliage that is truly garden worthy. Ninebarks aren't only about the leaves though. They may be at their best in summer when covered in clusters of white flowers.
