Hi, thank you to both.
@Gina1960 - the offset has only been growing for the last 6 weeks. It has grown exceptionally quickly and now I have noticed another small one coming off the stem. If I were to repot the banana now deep enough to cover the offset stems, would they send down roots eventually? When I originally repotted this plant, the pups were not there. It would be nice to be able to propagate at some point and have multiple plants.
@ardesia I believe it is a Musa Basjoo but I could be wrong.
