This hibiscus tolerates heat and humidity but does not do well when exposed to wind. Make sure the plant has access to lots of moisture for better flowering.

The Swamp Rose Mallow (Hibiscus) is also known as the dinner plate hibiscus because it can grow incredibly large flowers, as big as dinner plates.

Hardstem Bulrush is a tall, native perennial wetland plant that thrives in shallow water and saturated soils, often forming extensive stands in wetland and shoreline habitats. Well suited to riparian restoration, bank stabilization, shoreline protection, and naturalization projects, it spreads through underground rhizomes to form dense colonies.

Hardstem Bulrush’s tall growth provides valuable cover and nesting habitat for waterfowl, songbirds, and small mammals, while its late-summer seeds provide food for waterfowl and other birds.
