Hibiscus rosa-sinensis, Chinese hibiscus, China rose, Hawaiian hibiscus, and shoe flower,[ is a species of flowering plant in the Hibisceae tribe of the family Malvaceae, native to East Asia. Hibiscus rosa-sinensis was named by Carolus Linnaeus.
Hibiscus rosa-sinensis is a bushy, evergreen shrub or small tree growing 2.5–5 m (8–16 ft) tall and 1.5–3 m (5–10 ft) wide, with glossy leaves and solitary, brilliant red flowers in summer and autumn. The 5-petaled flowers are 10 cm (4 in) in diameter, with prominent orange-tipped red anthers.
Hibiscus rosa-sinensis is the national flower of Malaysia, called Bunga Raya in Malay. Introduced into the Malay Peninsula in the 12th century.
The flowers of Hibiscus rosa-sinensis are edible and are used in salads in the Pacific Islands. The flower is additionally used in hair care as a preparation. It is also used to shine shoes in certain parts of India. It can also be used as a pH indicator. When used, the flower turns acidic solutions to a dark pink or magenta color and basic solutions to green. It is also used for the worship of Devi, and the red variety is especially prominent, having an important part in tantra. In Indonesia, these flowers are called “kembang sepatu”, which literally means “shoe flower”.
Hibiscus rosa-sinensis is considered to have a number of medical uses in Chinese herbology. It may have some potential in cosmetic skin care; for example, an extract from the flowers of Hibiscus rosa-sinensis has been shown to function as an anti-solar agent by absorbing ultraviolet radiation.
