Re: Musa BasjooXhybridum
I don't really think it looks much like Musa basjoo. The petioles are quite flared on Musa basjoo, and almost closed on that one. The leaf bases are also acuminate on M. basjoo, whereas they are rounded on yours. The pseudostem on M. basjoo has no wax, your does, etc. If M. basjoo is a parent, the other parent is definitely the predominant phenotype.
Tony, that is definitely not Musa basjoo. Looks more like Musa balbisiana to me.
Stick it in the ground and see what happens!
