I just google it, it's like cherimoya, my brother told me he ate some really good cherimoya and saved the seeds and he planted a few of them, this year he had 5 good fruit from one plant, that is amazing. I'm tempted to let some of my papaya seeds that are sprouted from my compost pile to grow big and tall. However I don't like the look of the plant. It's kind of odd to see banana trees here in my hood.
