Hibiscus moschetos

Hibiscus moscheutos, commonly known as hardy hibiscus or swamp rose mallow, is a vigorous, sturdy, rounded, somewhat shrubby, hairy-stemmed, woody-based perennial of the mallow family. Showy, dinner plate-sized, hollyhock-like flowers last only 1-2 days, but new flowers open each day in rapid succession over a long July to September bloom period. At the peak of bloom, a large plant can produce 20 or more flowers per day. Seed capsules will float on water which facilitates seed dispersal.
 
Care:
Easily grown in average, medium to wet soils in full sun. Best in moist, organically rich soils, but does surprisingly well in average garden soils as long as those soils are not allowed to dry out. Regular deep watering is advisable. Immune to the heat and humidity. Tolerates some light shade, but full sun with good air circulation produces the best flowers, the strongest stems and the best environment for resisting potential diseases. Site in locations protected from wind to minimize the risk of wind burn. Pinch back growing tips when they reach 8” and again at 12” if bushy plants are desired. Deadhead individual flowers to maintain plant appearance. Cut back stems to approximately 3-4 inches in late autumn. New growth shoots are slow to emerge in spring. However, once new growth begins, it proceeds quite rapidly. Plants will benefit from regular fertilization during the growing season.
