In S China and in cultivation in general this species does not set fruit; the fruit description here is based on wild plants. The flowers of the cultivated plants range from yellow to dark scarlet red, and in recent years many new cultivars have been developed.

Cultivated in gardens in Fujian, Yunnan [native and weedy in Mexico, United States (Florida), and the Caribbean region, Central America, and tropical South America; cultivated as a perennial in tropical regions and an annual or indoors in temperate regions worldwide].
