Common Name: Hardy Hibiscus
Scientific Name: Hibiscus
While tropical Hibiscus flowers are associated with climates that are closer to the equator, hardy Hibiscus (also known as rose mallow or rose of sharon) are cultivated perennial hybrids that are hardy to zones 4 or 5. “Hybrid hardy Hibiscus cultivars are often the result of complex breeding work involving multiple species native to the U.S., including Hibiscus coccineus, Hibiscus laevis and Hibiscus moscheutos,” according to the Missouri Botanical Garden Plant Finder.
While they usually take a bit of time to put out new growth, hardy Hibiscus make a beautiful focal point in the garden with large blooms that come in a wide variety of colors, blooming mid-summer to early fall.
Find hardy Hibiscus throughout the Arboretum, including the Spiegel Entrance Garden, Elizabeth Carr Slade Perennial Garden and MacMillan Terrace Garden.
