Kosteletzkya virginica (Seashore Mallow)
It's easy to see why this native wildflower was chosen as the1989 North Carolina Wildflower of the Year. This large Mallow, native to marshes from New York to Florida and west to Louisiana, grows from five to six feet tall, with a spread about half that, and in late summer its stems are dotted with large, pink Hibiscus-like flowers with prominent yellow stamens. Its leaves are large, gray-green, rough, and slightly hairy, which don't sound all that attractive, but it's the flowers that matter with this plant. The individual flowers are fleeting, opening in the day and closing at night, but new flowers emerge the next day. It prefers full sun and moist, average soil and is ideal for the back of the border in Zones 6-9. Quarts.
