Hibiscus moscheutos
swamp mallow
This common wet-marsh species has large rounded leaves and larger white-to-pink flowers with a conspicuous darker center. Though late to emerge in the spring, this plant in full growth has a powerful effect; each flower lasts only a day, but once established, a clump of Hibiscus will keep flowering for weeks on end.
