Summary
Asystasia gangetica is an ornamental herb native to India, Malaysia and Africa. With its ability to reproduce by vegetative propagation and form dense vegetation mats, this species can be highly invasive. It can smother any vegetation with its herbaceous layer. Its introduction to the Pacific Islands has caused major disruptions in native ecosystems.
