It seems likely that peppers were domesticated simultaneously and independently in several different South and Central America locations. The plants seem to have been under cultivation by some time between 5200 and 3400 B.C. The Capsicums show great diversity in shape, color, taste and names. They are called aji, chile, chillis, pimentos, peperone or paprika. In writings from the early 1800s, bell peppers were often referred to as mangoes or mango peppers due to their association with pickled mangoes (the tropical fruit) being imported into the United States. In certain areas of the South, the name is still used.
