Genus of more than 200 species of deciduous and evergreen shrubs, trees, annuals, and herbaceous perennials, widely distributed in warm-temperate, subtropical, and tropical regions, in a variety of habitats. Hibiscus rosa-sinensis has so many varieties in so many colours and sizes! The large showy flowers come in shades of golden, pink, rose, yellow and orange, at times with colourful markings or double-petals. Some flowers grow to 1 ft. across. The state flower of Hawaii, the tropical Chinese Hibiscus is often grown in containers. All are heat-loving and flower during the warmest months of the year. Prune to control shape and fertilise monthly during the growing season. Protect from wind. Insects and diseases can cause problems. A Hibiscus bush can live for 20 years or more, and may be kept small by regular pruning - cut back stems in late winter to induce bushiness. It can also be trained as a standard.
