Hummingbirds and butterflies are quite fond of tropical hibiscus, Hibiscus rosa-sinensis. They are attracted to the bright yellow, orange, red, pink or white color of its bloom. They stay for the syrupy nectar that they find deep within the flowers. Tropical hibiscus attracts pollinators rather efficiently, but almost never generates seed. Most cultivars are hybrids.

Tropical hibiscus flowers are not overly profuse, but are about three or four inches broad. Fancy hybrids that bloom with broader flowers are not as vigorous as more typical sorts. Most cultivars bloom with somewhat ruffled single flowers. Some bloom with more ruffled double flowers. Both types of flowers have five garishly flaring petals. None are fragrant.

Tropical hibiscus grows as evergreen shrubbery about six to a bit more than ten feet tall. Pruning to remove congestion of inner growth promotes healthier outer growth. Besides, whitefly and scale insects often proliferate on crowded foliage. Leaves are mostly two to five inches long and two to three inches wide. Bloom continues from summer to autumn, mostly with warmth.
