Strobilanthes cusia, also known as Assam indigo or Chinese rain bell, is a perennial flowering plant of the family Acanthaceae. [1] Native to South Asia, China, and Indochina, it was historically cultivated on a large scale in India and China as a source of indigo dye, which is also known as Assam indigo. [2] In addition to being used for dye, it is also used in the traditional Chinese herbal medicine "Qingdai". [3] Other names for this dicot include Pink strobilanthes and Strobilanthes flaccidifolius, where flaccidifolius is Latin for "drooping leaves". [1]
