Today I found out that a banana is a herb. I know, weird right? I didn't believe it so I googled it and this is what I found. (on http://www.askoxford.com/asktheexperts/faq/aboutother/banana?view=uk)
Is a banana a fruit or a herb?
Both. A banana (the yellow thing you peel and eat) is undoubtedly a fruit (containing the seeds of the plant: see answer regarding tomatoes), though since commercially grown banana plants are sterile, the seeds are reduced to little specks. However, 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.
WEIRD... lol :D
