musas in wva

Can someone help me out with this? I have a Rojo banana. I assumed that the poorly labeled plant was really a Zebrina, which is supposed to be a seeded inedible variety. I was considering taking it out to make room for an edible variety, especially since this one has pupped like crazy and is starting to take up some real room. We decided to cut open one of the unripe bananas on it to see how badly seeded it is, and we found that it is not seeded at all. Just those little undeveloped seeds that you find in the edible varieties. So two things come to mind, that I have an edible variety that looks exactly like a Zebrina, or that in the enclosed environment of the conservatory, I do not have pollination, therefore my "seeded" variety won't produce seeds, making it actually edible. We have found this to be the case with the papayas - if I pollinate a bloom with another flower, we get a seeded papaya, if I leave it alone we get a seedless one (much easier to eat!) If any of you can answer this, I'd be very grateful!
