Rose Mallow (Hibiscus militaris), also known as Swamp Rose Mallow, is a striking native perennial prized for its large, showy pale pink flowers with deep rose centers. Blooming in mid to late summer, the 4–6 inch blossoms create a bold tropical look in temperate gardens.
This hardy hibiscus grows 4–7 feet tall with upright stems and attractive green foliage. Native to wetlands, riverbanks, and moist meadows of central and eastern North America, it thrives in consistently moist soil and tolerates periodic flooding.
Despite its lush appearance, Rose Mallow is cold hardy and returns each year from the root crown. Its nectar-rich blooms attract bees, butterflies, and other pollinators.
