Sorry, I'm in Southeast Florida (10a), I have two different types of nannas left from the nearly dozen I originally had, I pulled the ones that I either didn't like or had a growth habit I did not like. They grow really well here.
They were in Lowes and there was no grower info on the hang tag.
The reason I'm wondering is every variegated cultivar I've seen either has inedible fruit, or are ornamental only. Some places talk about "the small edible seeded fruit" indicating they are a species not cultivar?
The hang tag not only has the typical "Grow your own, enjoy your harvest" verbiage it also has "edible" fruit specific wording like Nutrition facts of Musa Rojo, "This fruit does not need a pollinator" and a list of pollinators but says it's self fertile?
I bought it on the off chance it actually does produce edible fruit, if not? Well I'll get to that when I get to that.
PS. Wiki has a page on it and says they are edible:
