Scarlet rose mallow is an herbaceous perennial in the Malvaceae (mallow) family. It is native to the southeastern United States and is sometimes called swamp hibiscus because it is native to marshes and swamps in Alabama, Georgia, and Florida. It can grow 6 to 8 feet tall and 2 to 3 feet wide.

Plant in locations with full sun to partial shade and with moist, occasionally wet soils.

Flowers of red hibiscus mature in late summer to early fall and are very large and striking, up to 6 inches wide. The large, bold leaves add to the striking effect. It can be used in wet areas, such as beside ponds or in boggy areas.

Scarlet rose mallow is a large plant for the rear of the perennial border, mixed border, or courtyard. It is also effective when grouped in moist locations along edges of ponds and streams or in a rain or pollinator garden.

Hibiscus does tolerate pruning, but keep in mind that flowers will appear on new growth.
