This plant grows in rice fields and along watercourses and is often considered a weed that can cause great damage in rice fields.
Monochoriaŭ hastata, however, has its uses. In parts of Australia and Southeast Asia, the young leaves and stems of the plant are eaten as a vegetable. It is also used in traditional medicine to treat infectious diseases and skin ulcers. In China, it is used to make a medicinal tea. The plant is known for its antibacterial properties and is therefore used in natural medicine. Another use is in aquarium keeping, where it serves as decoration and shelter for fish. Its leaves are also used as food for fish in aquariums. In addition, if properly handled, Monochoria hastata can serve as an effective tool for soil conditioning and preventing erosion.
