According to the Department of Agriculture, many varieties of bananas grow freely all over Sri Lanka, all year round. They are cultivated in large, medium, and small-scale orchards, and in home gardens. While there are said to be almost 1,000 varieties of bananas in the world, which subdivide into about 50 groups, Sri Lanka boasts of 29 varieties, the greater number of which appear to be indigenous to the country (although several are said to have been brought from South India, or scientifically introduced to SriLanka).
