Physocarpus opulifolius Red Baron, otherwise known as Ninebark, is a hardy perennial shrub with attractive foliage that changes colour through the year. The dark rich foliage stands on red stems that produces pretty clusters of pinkish-white flowers in the early summer months. The flowers appeal to butterflies and bees, where small red fruit develops and attracts birds into the garden. This dramatic shrub can reach a mature height of up to 2metres and will thrive in most soil types and requires little maintenance. It is happiest in sunny spots, although can also tolerate more shaded areas and can be grown in containers dependant to the size of garden.
