Description: Physocarpus opulifolius (Green Ninebark) is a hardy deciduous shrub known for its attractive green foliage, clusters of small white to pale pink flowers in late spring to early summer, and distinctive peeling bark that adds winter interest. The lobed, serrated leaves create a dense, bushy habit, making it an excellent choice for hedging, screening, or mixed borders. In autumn, the foliage takes on warm yellow and bronze tones before falling. This tough, low-maintenance shrub thrives in well-drained soils and tolerates a range of conditions, including drought, poor soils, and cold climates.
