Discussion
Gossypium hirsutum is part of the littoral vegetation in the Florida Keys and around the coasts of the Gulf of Mexico and the Caribbean Sea. The species is found also as the dominant agricultural crop of the Cotton Belt, from California to the Carolinas; it is cultivated worldwide in suitable climates. The species may be found also as an escape, or from cotton mulch used in gardens or from waste around areas of cotton agriculture (fields, gin yards, roadsides, and other places).
