Swamp rosemallow is a deciduous perennial wildflower with showy pink blooms. Its solitary flowers are large and somewhat nodding; they have 5 whitish-pink to rose-colored petals and red centers. Leaves are deltoid to heart-shaped, have toothed margins and are alternately arranged. They are grayish-green in color and velvety, giving the foliage a silvery tone. Stems and bracts are pubescent, as are the capsules (fruits).
Swamp rosemallow blooms from summer into early fall. It occurs naturally in marshes and swamps, in wet ruderal areas, and along edges of lakes, ponds and rivers. It is often seen in large masses in open marsh areas.
