Hi, I purchased a banana from Ebay specifically called California Gold from the guy who discovered it. He had links showing a local news story that was on him from around 1992. Here is a link about the information on this banana

If you select varieties you can read about this persons ideas on the California Gold. Here is a direct link.
ENCANTO FARMS. I am in Massachusetts. I have no expectations of this surviving our winters. I just thought the hardier the better. I am currently trying to built a lean to on the house to overwinter this banana in a pot.
In my opinion the ebay listing is too generic. He should know the exact variety he has and its origin.
Hope this helps
Tom
