I would not call it a dwarf tree. I have a medium sized tree and it’s about 9 ft tall at this point. My main issue with it is that it is not precocious. The fruit is delicious, but given the lack of production I suspect it is overall an inferior tree compared to the other outstanding varieties (alano, Silas wood, hasya etc). The fruit is only marginally better than those excellent but more productive varieties IMO.
I would call it a collectors sapodilla. It is not an “insurance” sapodilla. Definitely would not recommend if a grower only has room for one sapodilla in the yard.
