Hibiscus hybrid Hibiscus hybrid

Hibiscus hybrids are 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. Deep and consistent watering is advisable. Tolerates some light shade, but full sun with good air circulation produces best flowers, strongest stems and the best environment for resisting potential diseases. Site in locations protected from wind to minimize risk of wind burn. Deadhead individual flowers immediately to maintain plant appearance. Cut back stems to approximately 3-4 inches in late autumn.  This plant is slightly salt tolerant.

Hibiscus hybrid is a vigorous, sturdy, erect but sometimes shrubby, woody-based perennial that typically grows to 4-8’ tall. Hibiscus hybrid plants are often complex mixtures of different species which are native to the U.S., including H. coccineus, H. laevis, H. militaris, H. moscheutos and H. palustris. Hybrids are winter hardy to USDA Zones 4 or 5 which significantly distinguishes them from the many tropical to semi-tropical hibiscus on the market today.  Individual flowers remain in bloom for only one day, but one or more flowers usually open each day, in succession, over a long mid-summer to early fall (sometimes to first frost) bloom period.
