That is an interesting cross. My pitangutaba looks nothing like my pitomba. I would have never guessed these were close enough genetically for a viable cross. Maybe I will try to graft a few branches of each onto the other to attempt a hybrid of my own or improve fruit set.
I realize ‘tuba gets a lot of mixed reviews, but I really enjoy the mix of mango/passion fruit flavor I get from the fruit. An it held fruit under a foot tall on its own.
