Hibiscus Cousins - Rose of Sharon, Swamp Mallow & Texas Star
By Jan Brick
Galveston gardeners share a distinct fondness for hibiscus, as evidenced by the proliferation of these plants in landscapes and gardens all over the isle. However, there are three varieties that are sighted less often than others—the cousins. With over three hundred species, Hibisceae is the largest clan of the family Malvaceae, a group of flowering plants with over four thousand species including okra, cotton, and cacao. Popular hibiscus such as Rosa Sinensis, the Bahama Bay Collection, Hollyhocks, Confederate Rose and Turk’s Cap are cousins to the lesser-known Althea, Swamp Rose Mallow, and the Texas Star.
