Antigonon leptopus is cultivated widely as an ornamental in warmer parts of the world and is grown extensively in South America. In the flora region, it appears to have naturalized only in Florida and southern Texas; records from elsewhere probably represent plants that have persisted from cultivation. It propagates easily by cuttings and seeds, and the tubers are edible.
