Swamp Rose Mallow

About Swamp Rose Mallow

Swamp Rose Mallow is a true showstopper of the native wetland world, offering some of the largest flowers of any plant in North America. This vigorous perennial forms a large, shrub-like clump reaching 3 to 7 feet in height, adorned with broad, ovate leaves. From mid-summer into early fall, it produces breathtaking blossoms that can span nearly 8 inches in diameter, typically appearing in shades of white or pink with a prominent dark red center. Its native range extends across the eastern half of the continent, where it is a common sight in brackish marshes, swamps, and along lake shores. The nectar-rich flowers are a favorite of the specialized Hibiscus Bee and various swallowtail butterflies. To thrive in your landscape, give it a spot with full sun and consistently moist to wet soil; it is particularly well-suited for the edges of water features or in heavy clay soils that retain moisture. Despite its delicate appearance, it is a hardy and resilient plant that returns reliably each year to brighten the summer garden.
