the banana plant, though it is called a 'banana-tree' in popular usage, is technically regarded as a herbaceous plant (or 'herb'), not a tree, because the stem does not contain true woody tissue.
HELLLOOOOO Its a banana. You find them in the fruit section of supermarkets. You dont go into your back graden pick a few sprigs of mint, rosemarry and BANANA. Its a fruit!
okay, lets be clear. The plant that the banana grows on is a herb. This is because it has no true woody tissue (wikipedia) The banana itself is a fruit. Okay? Good!
