Is there such thing as a banana tree?
No, Banana tree is not a tree… It is a herb and it is often mistake as a tree… Herb: a) A plant whose stem does not produce woody, persistent tissue and generally dies back at the end of each growing season. b) Any of various often aromatic plants used especially in medicine or as seasoning. Tree: a) A perennial woody plant having a main trunk and usually a distinct crown. b) A plant or shrub resembling a tree in form or size.
Bananas are the fruits of a herbaceous perennial, commonly called a banana “tree” but not really a tree. While the morphology is similar to a “tree”, it is not the same. If I recall correctly, (not really sure about this) the difference is part of the banana plant’s growth dies yearly, rather than being incorporated into the next year’s growth like a tree, hence the ‘herbaceous perennial’.
