Well, we couldn't stand to wait any longer and went ahead and harvested two egg-sized (undersized) fruits. They were partially filled with little red jewel-like "seeds" but many of the seeds hadn't developed. I'm guessing maybe it's a case of poorly pollinated flowers. Even so, these first fruits were sweet-tart and juicy - pretty good! I took a bunch of cuttings to see if I can propagate it. And soon I think we'll have to harvest the rest of the fruits including the two bigger (tennis ball to baseball sized) fruits. Of course, we'll be planting all of the seeds too. Gotta see what kind of variability we might get.
