The Neches River rose mallow is a federally listed candidate endangered native Hibiscus that now only exists in three wetlands in E. Texas. This Hibiscus has delicate slender finely divided leaves on long, arching 3-7 foot long stems. The creamy white flowers are 3-6 inches wide with dark burgundy eyes, bear five 2-4 inch long petals and appear from June through August. Occasionally the flowers bear pink petals. Plants often bloom into October depending upon water availability. This Hibiscus is distinguished from other native Hibiscus in that its flower has a densely pubescent calyx and bracteoles and its mature seeds are densely pubescent as well. Budding and leafing normally occur late March-April and fruits are present from July through November.
