Pima cotton (Gossypium barbaense), also known as Extra Long Staple, South American, Creole, Sea Island cotton, Egyptian, Algodon pais, and West Indische katoen, is a species of cotton plant which is widely cultivated though it originated in Peru. It is a tropical perennial plant that produces yellow flowers and has black seeds. It grows as a small, bushy tree and yields cotton with unusually long, silky fibers. In order to grow, it requires full sun and high humidity and rainfall. G. barbadense is also very sensitive to frost.
