Re: The cold hardy list
Nice album redflash. You've got some really nice plants, especially the Musa sikkimensis 'Red Flash' varigated. Did you grow it from seed?
I noticed that a couple of your other plain(without red marks) Musa sikkimensis looks like a hybrid. It has alot of wax, and the where the petioles meets the leaf they are recurved. Maybe Daj Giant or thompsonii hybrid?
What Musa is the third picture? Looks alot like Thompsonii.
