The banana is a perennial plant that replaces itself. Bananas do not grow from a seed but from a bulb or rhizome. The time between planting a banana plant and the harvest of the banana bunch is from 9 to 12 months. Bananas are the most popular fruit in the world. In fact the banana is not a tree but a high herb that grows up to 15 metres. Bananas are grown in more than 150 countries, producing 105 million tonnes of fruit per year.
