    Seashore Mallow is a perennial with several stout stems arising from the crown. Very pretty 2-inch pink flowers similar to those of Hibiscus terminate the 4- to 6-foot stems. Flowering is from July to October. Give Seashore Mallow full sun, well drained soil and room to spread. At the rear of the perennial garden or as the backdrop for other lower plants, Seashore Mallow is very effective with its bright pink flowers coming during the season when yellows predominate.
