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 of the deep South. 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.
‘Luna Blush’ by reputation branches well without pinching and may be grown from seed.
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. It typically grows to 3-7’ tall and to 2-4’ wide. It is native to wet spots (marshes, swamps, floodplains, river banks, moist meadows, and moist woods) from Ontario and Massachusetts south to Ohio, Indiana, Alabama and Florida. Showy, dinner plate-sized, hollyhock-like flowers (each to 4-6” diameter) have five overlapping white, creamy white or pink petals with reddish-purple to dark crimson bases which form a sharply contrasting central eye. Each flower has a prominent and showy central staminal column of white to pale yellow anthers surrounding an even longer style. Individual 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. Flowers (to 6-9” wide) are among the largest flowers produced by any perennial that is winter hardy to the St. Louis area. Alternate, broad-ovate to lanceolate leaves (3-8” long) with toothed margins are green above and white-hairy beneath. Leaves are lobeless or have 3-5 shallow lobes. Seed capsules will float on water which facilitates seed dispersal.
