Swamp Rosemallow
Hibiscus grandiflorusAlso known as Large-flowered Hibiscus, Velvet-leaf Rosemallow, Pink Swamp Hibiscus
Swamp Rosemallow rises tall above coastal marshes and lake margins, bearing velvety heart-shaped leaves and massive pale pink blossoms with deep crimson centers. Opening in the warmth of summer mornings, each flower lasts only a day but gives way to a continuous cycle of fresh blooms through early autumn. Its dense, shrubby stems create vital shelter for wetland birds while deep root systems help stabilize soggy shoreline soils.
