Hibiscus coccineus (Scarlet Rosemallow) is a striking perennial that thrives in wet soils and is well-suited to full sun. It grows up to 10 feet tall, often forming clumps, with palmately divided, shiny leaves and large, deep-scarlet flowers that can exceed 6 inches in width. Blooming from May through September, Scarlet Rosemallow is a showstopper in any garden, particularly in swampy or marshy areas. This Texas native is admired for its bold, crimson flowers, making it one of the most attractive native species in the mallow family.
