It could possibly be selfing, or it may be pollinated by diploids, which would likely produce triploid seedlings. Let the other fruit drop when ripe and you should get some ripe seeds. My guess is the fruit would not taste good, but who knows? Try it and let us know. And take a photo of the fruit and the arils to share with us if you can.

My Inspiration fruited last year, but only produced a few mature seeds. None germinated for me. I assume my incarnata pollinated it, which would've produced a triploid seedling.
