The Pink banana (Musa dasycarpa, formerly known as Musa velutina) is banana species that originated from Assam. This species is known for its strikingly pink flowers. It is a rather smallish banana plant, that is typically used for its ornamental appeal. Normally, its height will not exceed two meters. One of its other appealing aspects is that it usually flowers within a year.
In other words: if you want to grow an attractive and not too large banana in your own home, the pink banana is certainly a very good choice.
