Neptunia oleracea (not to be confused with Neptunia plena) is a species of flowering plant in the legume family, Fabaceae. It is sometimes referred to in English by the common names water mimosa or sensitive neptunia. It is pantropical nitrogen-fixing perennial legume. Genus and common name come from Neptune, god of the sea, in reference to the aquatic habit of some species in the genus. Its specific epithet oleracea means "vegetable/herbal" in Latin and is a form of holeraceus (oleraceus).
