September Blooms in my Georgia Garden: Hibiscus mutabilis, Confederate Rose

One of the most requested plants in our garden is the Confederate Rose. You will probably never find this plant in a big box store, and it's hard to find it in any nursery. Yet, this elusive old Southern plant is a favorite of many gardeners.

Confederate Rose is not really a rose, but a Hibiscus, Hibiscus mutabilis, to be exact. 

The blooms of the Confederate Rose are voluptuous, like one might expect from a flower in the South. Although single flowers are out there, I have seen only the many-petaled, double blooming variety that opens light pink and gradually changes to a deep rose-pink on the third day after opening. It is the changing of the bloom color that gives the plant its botanical name, Hibiscus mutabilis. Blooms can be up to 6 inches across. All those petals remind me of the many fluffy layers of the petticoats worn by Southern belles of antebellum times here in the Southeastern United States.

Despite their popularity and ability to thrive in the Southeastern US, Confederate Rose is not native to the South but comes from China. They thrive in the South anywhere that they have time to open their very late flowers before fall frost. This species is a popular passalong plant. 

Height varies from about 8 to 15 feet and the plant grows wider every year (kind of like me, apparently.)

Confederate Rose is an eye-catching foliage plant even before bloom, with large, soft, gray-green maple shaped leaves. 

Like all plants in the Hibiscus family, Confederate Rose grows best in full sun with regular water, but it will bloom quite happily in part shade. This is true especially in areas with very hot temperatures lingering into its bloom time of late summer and early fall. Although this Hibiscus does love water, it can withstand periods of drought that is common in the Southeast.

Confederate Rose will grow in regular garden soil, but it will grow larger and develop more blooms in good fertile soil. 

Once winter frosts burn back the foliage, the entire plant can be cut back to make the garden more tidy. This can be done any time during the winter or early spring. Near the coast, you can let the stems stay if you don’t mind the plant becoming very large. Confederate Rose will resprout from current branches where winters are mild. However, the plant will become 10 feet tall by summer’s end, even when cut back the previous season.  Make sure to plant it where it has plenty of room to spread out.

Confederate Rose is Really a Hibiscus

Confederate Rose is a very tall perennial that grows like a shrub in most of the South. Near the coast it will leaf out on old stems, but in most areas, the tops will die back, and the plant will regrow each spring from the base.

Despite their popularity and ability to thrive in the Southeastern United States, Confederate roses are not native to the United States but come from China. They thrive in the South anywhere that they have time to open their very late flowers before fall frost. This species is a popular passalong plant not usually available in your local nursery.

Height varies from about 8 feet in the northern parts of Georgia and Alabama to about 15 feet on the coast.

Confederate Rose is an eye-catching foliage plant even before bloom, with large, soft, gray-green maple shaped leaves. Large blooms four to six inches wide open in September or October. Both double and single flowering forms are available. It is the changing of the bloom color that gives the plant its botanical name, Hibiscus mutabilis. The blooms open as a very soft pink and darken gradually to a deep pink the third day after opening. When in full bloom, the plant appears to have 3 different colored flowers all on the same bush.

Confederate Rose grows best in full sun or part shade. Although average garden soil is fine, the plant will grow larger and bloom more in good fertile soil.  As with all plants in the hibiscus family, Hibiscus mutabilis needs regular water to grow and perform well, but can withstand drought. Water whenever you see the large leaves droop.

Once winter frosts burn back the foliage, the entire plant can be cut back to make the garden more tidy. This can be done any time during the winter or early spring. Near the coast, you can let the stems stay if you don’t mind the plant becoming very large, since Confederate Rose will resprout from current branches where winters are mild. Even when the plant is cut to the ground, it will become 10 feet tall by summer’s end. You cannot make this plant stay small and compact, no matter what you do. Confederate Rose is meant to be a flamboyant, voluptuous focal point in the garden. Make sure you plant it where the large size can be appreciated.

Fragrant Jasmine

Trachelospermum jasminoides is a very fragrant Jasmine that is known by several different common names. Star Jasmine, known as Confederate Jasmine in the Southeast, is an evergreen plant that can be grown as a vine or groundcover. The fragrance is heavenly in late spring when it blooms most profusely, but the plant will rebloom sporadically throughout the summer. Shiny dark green leaves turn red in winter, adding to the year round beauty of the plant. Trachelospermum Jasminoides is often grown as a houseplant where it isn't hardy outdoors, but Confederate Jasmine is hardy in USDA Zones 8 -11. Preferring part to full shade, the Star Jasmine makes a great privacy screen when allowed to climb a trellis or fence. It makes a great container plant too, where it will continue to thrive if it must spend the winter indoors. This jasmine is a moderate to fast spreader, yet it isn't considered invasive. There are no known pests or diseases involving this plant. Confederate Jasmine, or Star Jasmine, would make a beautiful addition to any Southern garden.
