Swamp Rose (Rosa palustris)

Swamp Rose (Rosa palustris)

The Swamp Rose is North America’s only truly wetland-adapted native rose — a thorny, arching shrub that blooms in deep pink clusters along bayou edges, pond margins, and floodplain swales. Where other roses struggle in wet feet, Swamp Rose thrives, bringing fragrance and color to the water’s edge from June through August.

Swamp Rose provides nectar for native bees, bumble bees, and butterflies. Its red hips persist through winter and are consumed by mockingbirds, cedar waxwings, and small mammals. It provides dense nesting cover for marsh birds and is a larval host for several native moth species.
