Discussion
The flowers of Hibiscus grandiflorus first open in the evening, emit a pleasant fragrance, and are pollinated by sphingid moths (O. J. Blanchard 1976). It is relatively common only in Florida. Hibiscus grandiflorus is sometimes cultivated and has been found to be hardy as far north as Illinois (S. R. Hill, pers. comm.).
