|discussion=<p>The flowers of <i>Hibiscus grandiflorus</i> 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. <i>Hibiscus grandiflorus</i> is sometimes cultivated and has been found to be hardy as far north as Illinois (S. R. Hill, pers. comm.).</p>
