The species is indigenous to tropical and subtropical regions of the New World, from South America (French Guiana, Guyana, Surinam, Venezuela, Brazil, Bolivia, Colombia and Argentina) to Central America (Belize, Costa Rica, Guatemala, Honduras, Nicaragua, El Salvador, Panama, Mexico) and the Caribbean (Bahamas, Cuba, the Dominican Republic and Haiti) to Florida in the Southeastern United States.
The species has become widely naturalized in the tropical regions of the world, including Asia (Indonesia, Japan (Ryukyu Islands), Brunei, Malaysia, Myanmar, Nepal, New Guinea, Philippines, Sri Lanka, Thailand) and many Pacific islands (American Samoa, French Polynesia, Hawaii, Tonga, New Caledonia, Fiji and the Galapagos Islands) and in Australia—southeastern and central Queensland and the coastal districts of northern New South Wales. It has also naturalized in Lord Howe Island and Norfolk Island.
The species thrives in a warm and humid climate. This species has escaped cultivation and invaded watercourses, riparian areas, moist forests, urban bushland and disturbed areas (e.g. in parks and along roadsides and railway lines) in the subtropical and tropical regions of the world.
