Habitat/ecology:  In South Africa, "watercourses, forest margins, roadsides, urban open space in moist, warm, coastal and inland regions" (Henderson, 2001; p. 40). "In Fiji this well-known plant is cultivated or perhaps sparsely naturalized along roadsides near sea level" (Smith, 1979; pp. 214-215). In the Cook Islands, "naturalised; land, lowlands - inland valleys" (McCormack, 2006).

Propagation:  Vegetatively propagating or possibly bird dispersed seed. Aquatic dispersal is also apparently occurring along streams (Oppenheimer, 2008; p. 35).

Native range:  Eastern Asia (East Indies) (Henderson, 2001; p. 40). "New Guinea or some neighboring part of eastern Malesia, but it has long been in cultivation and now occurs in most tropical countries" (Smith, 1979; pp. 214-215).
