Bananas in Wales. The Cavendish Banana is the common banana that we eat in Europe. The commerical bananas have no seeds and are propagated by offshoots or 'pups' as they are known. The picture shows the young fruits starting to emerge from the stem. It took a further three months for them to fully mature. In the wild, the flowers (see yellow petals) are pollinated by fruit bats which also disperse the fruits. We have bats to thank for bananas!
