Swamp mallow, sometimes called swamp hibiscus, is native to North Carolina's swamps and marshes. It performs well in wet parts of the garden, but also grows well in shrub borders or anywhere in the landscape where it can receive regular watering. It quickly grows to a height of up to 7 feet and dies to the ground in winter, then reshoots in spring. The flowers are usually about 6 inches across, and some cultivars have flowers that are a foot in diameter. Species flowers have white or light pink petals with dark crimson centers, and cultivars come in a wide range of colors. Swamp mallow likes a rich, organic soil and full sun. Fertilize regularly and mulch well to help the soil retain moisture.
