Hibiscus palustris, commonly known as Crimsoneyed Rosemallow or Swamp Rose Mallow, is a semi-deciduous shrub that is typically designated a variety of Hibiscus moscheutos, rather than a separate species. It is native to wetlands and marshy areas in the Eastern United States. This plant typically grows to a height of 3-7 feet (0.9-2.1 meters) and a width of 3-6 feet (0.9-1.8 meters). The Crimsoneyed Rosemallow is characterized by its large, showy flowers with colors ranging from pink to red, with a prominent crimson spot at the base of each petal. The blooming period occurs in the summer and fall, adding a splash of color to the garden landscape.

The Crimsoneyed Rosemallow is valued for its striking flowers and ability to attract pollinators such as butterflies and hummingbirds. It is often used in rain gardens, wetland restoration projects, and as a naturalizing element in water gardens due to its affinity for moist environments. While it thrives in full sun, it can also tolerate partial shade. It requires consistently moist to wet soil conditions and can even grow in standing water. This makes it an excellent choice for areas that are difficult to plant due to poor drainage. Despite its preference for wet conditions, it is relatively low maintenance once established. Gardeners should be aware that it can be susceptible to rust and leaf spot diseases, and in some areas, it may spread aggressively if conditions are ideal.CC BY-SA 4.0
