Congrats on the fruit! I was able to get some fruit from PR last year. It truly is a great fruit, but it wouldn't be on my top 5 (I think that caimitos taste better). Nonetheless, I am growing it in my greenhouse. I have tried to graft onto it, but have failed. If any of you out in FL would be willing to spare some scions next spring, please let me know. It is a shame that there are very few varieties of named abiu in the US, and even then, they are still hard to find.
