idk, i've had fruiting pitangatuba for about 5 years. I do understand there is improved variety. Hey, same with suriname cherry...However, not searching for those. I don't see how it can be improved. It's an ornamental and conversation piece in my garden so it stays. But, hopefully my point of view of someone who is NOT trying to sell you a plant weighs heavy. Everyone who has tasted it spits it out immediately. But, I have other friends who are growing it and they concur with my assessment.
It should be labelled as super tart and barely edible to only those with taste buds that can tolerate it. Like I said, even tried it with miracle fruit. So many other good berry fruit to grow, unless you really want one, Pitangatuba is a fun word to say but do not recommend it for eating.
For growing culture, it is very easy to grow. Does better with moisture, but mine has survived droughts and a few hurricanes have shredded it but it recovers. Its pretty when it is flowering and holding fruit. Its amazing how quick the fruit plumps up. its hidden then all of sudden you walk by it and there is big and plump fruit. Falls to the ground very easy, perishes quickly. Maybe used as a jelly if you got time to make jelly.
