Asystasia includes approximately 70 species of perennial herbs and subshrubs from tropical Africa, India, and Asia. Asystasia gangetica has become widely nuturalized and is invasive in many coastal areas of the tropics. It is quite variable and possibly represents a hybrid gene pool. It is often encountered as a weed in lowns. In established beds, these pretty weeds can be kept under control by mulching. The funnel – shaped flowers are arranged along one side of the inflorescence stalk – Bracts are small and not showy.
