Okay, quick update on that "thai restaurant, most likely namwah" banana plant from the previous page of this thread. To recap, I traded an FHIA-1 American goldfinger for what is likely a namwah, and it was a dream come true. The corm I dug up had zero roots because the soil was rock hard, but with a lot of babying and weeks of warm weather, it's fully established! It was put into the ground this past weekend and it'll probably take off pretty soon.
Here's the plant before going into the ground. It had just started to get root bound and some roots had crept out of the pot and into the ground:
After digging a hole, mixing in a lot of decomposed organic matter, topsoil and chicken manure, the plant has been put into its new permanent home. This site gets blazing sun from about 10am until sunset, pic taken 8/6/17:
