Hibiscus moscheutos, or rose mallow, is also called hardy hibiscus. This hibiscus is native to wetlands of the Southeast and has been extensively hybridized. Some hybrids are referred to as dinner plate or Frisbee hibiscus, due to their large, showy flowers. Hardy hibiscus is easily grown from seed in rich, well-drained soil. Hibiscus moscheutos are slow to mature and may not be cold hardy until they are 2 to 3 years old, but then are hardy to zone 4 with heavy winter protection and require no protection in warmer climates.
