Although the banana can be found throughout the tropics, it is a native fruit to South East Asia. Reference to the banana was first made in the Epics of the Pali Buddhist canon in 500 BC. Bananas were exported to Africa from Indonesia around 1,500 years ago. Consequently, reference to this fruit can be found in the Koran as the Tree of Paradise.
The banana plant has no woody tissue, so it is not considered a tree at all, but a giant herb. The banana plant can grow to height of 4 to 8 m, depending on the variety. Today, Vietnam boasts 28 different varieties of banana from plantains (used in cooking) to the dwarf banana (finger size).
