Hardy Perennial Hibiscus

Hardy Perennial Hibiscus is one of our summer favorites and now available. Also known as Rose Mallow, these plants are large, fast-growing, and cold hardy. They are valued by gardeners for their huge exotic flowers and showy foliage which make for a perfect addition to any perennial border. Because of their size, they are a great choice to plant against a large fence or wall, or as a showy substitute for many small and medium shrubs. Most varieties produce beautiful blooms in white, pink, red and bi-colors, with individual blooms lasting for one or two days. Hibiscus are slow to awaken in spring, waiting until the soil has warmed, but once their foliage emerges in early June, they take off. They generally start flowering in July and last until frost so they make a perfect late summer addition to your garden!
