My trees started fruiting a year or two ago, not sure as I wasn't around. But the boys at the farm liked them a lot. Managed to get a single fruit to our friend in Germany, but didn't taste it myself - will do so next time. The correct name is Mimusops balata, as both M. commersonii and M. maxima are synonyms.
My trees are upright by the way, thanks for the seeds Mike.!
