It is grown in South East Asia, China, India and the Philippines. It is also widely cultivated as an ornamental plant in tropical and subtropical areas. It is a small to medium-sized tree growing to 20 m tall, with smooth, flaky bark. The leaves are deciduous, oval to elliptic, 8-15 cm long and 3-7 cm broad, with an acute apex. The flowers are produced in erect panicles 20-40 cm long, each flower with six white to purple petals 2-3.5 cm long.
The leaves of the Banaba and other parts are used widely by the Philippines, Taiwan, and Japan as a Tea preparation.
