Swamp Rosemallow
Hibiscus grandiflorusAlso known as Large-flowered Hibiscus, Velvety Rosemallow, Great Rosemallow
Swamp Rosemallow stands out in southern wetlands with massive pale pink flowers accented by deep crimson centers. Its velvety, grey-green leaves feel soft to the touch and help distinguish it from related mallows even when not in bloom. Each individual blossom lasts only a day, but plants produce a succession of flowers from midsummer into autumn that attract native bees and hummingbirds.
