Hill bananas (AAB, two ecotypes Virupakshi and Sirumalai) are grown at a height of 2000 to 5000 feet with well distributed annual rainfall of 1250-1500 mm in the lower Palaini, Sirumalai and Kolli hills. Hill bananas, unique to the state of Tamil Nadu, are known for their special flavour and long shelf life. Hill bananas are perennial in nature, cultivated along with coffee and pepper also as a multitier system. Hill bananas are highly susceptible to Banana bunchy top virus (BBTV). BBTV has been the sole cause for reduction in Hill banana cultivation from 18,000 ha in 1970s to a mere 2,000 ha at present.
