Cotton was originally a tropical plant

Cotton was originally a tropical plant, but, strange to say, it seems to thrive best in temperate zones. The cotton plant does best, according to Newman, in climates which have (1) six months of freedom from frost; (2) a moderate, well-distributed rainfall during the plant's growing period; and (3) abundant sunshine and little rain during the plant's maturing period.
