Banana Fanna Foe Fanna

I recently acquired a few Musa cultivars. I've never grown bananas, but they're giant herbs so how hard can it be. I have a pair of each of the following:

• M. 'Thousand Fingers'
• M. 'Gros Michel'
• M. 'Dwarf Iholena'

They're little ones, but they seem to be growing already just after potting them, so who knows what they'll turn in to and how fast they'll do it. I think I'll be up potting in no time.

Then I picked up one more that is quite large, and it's a dwarf variety. I don't know what it is, but it's a Thai cultivar.
