Chinese hibiscus, Hibiscus rosa-sinensis
The Chinese hibiscus (Hibiscus rosa-sinensis, family Malvaceae) is an evergreen shrub indigenous to East Asia. Also known as China rose and Shoe flower, it is widely grown as an ornamental plant throughout the tropics and subtropics. The flowers are large, red, and firm, but lack any scent. Numerous cultivars, varieties, and hybrids have been created, with flower colors ranging from white through yellow and orange to scarlet and shades of pink, with both single and double sets of petals.
Hibiscus rosa-sinensis is the national flower of Malaysia, called the Bunga Raya in Malay. The flowers are used to shine shoes in parts of India.
