Swamp rose (Rosa palustris) is one of many water-loving, water-absorbing plants selected for the Rainwater Glen. An Illinois native plant, it grows in marshes in northern Illinois, in the bald cypress swamps in southern Illinois, and near rivers, stream, and ponds throughout the state. The large, red visible follow fragrant pink flowers that bloom in early summer. Swamp rose is used in home landscapes with full sun and moist, acidic soil, and room for colonies to form.
