In 1915, Marsh fleabane was first collected in Hawaii and is native to Asia, China, Philippines, and Northern Australia, from India eastwards, and has become naturalized on several islands of the Pacific Ocean. It is one of Southeast Asia’s most well-known indigenous medicinal plants and is traded locally, particularly for its use as a diuretic, provides edible leaves, and is grown as a hedge in gardens.

In particular, Marsh fleabane occurs along the seashore, coastal streams, and swamps, on clay or hard and stony soils, often in sunny or slightly shaded areas near salt springs in the interior. It is grown as a hedge on fertile soil in the lower regions, often up to an altitude of 1,000 m.
