Thanks for all the great responses,
Now:
Which cultivar should I plant? Partial Shade? Full sun? Irrigation? THANK YOU
I would recommend planting a seedling and then grafting it with any good tasting fruit. I wouldn't bother looking for a specific cultivar in Florida since the only nursery with named cultivars that I know of is Excalibur and last I checked the smallest size grafted Malay apple they had was in a 25 gallon or so.
HMHausman on the forum had a seedling Malay apple tree growing in Davie that took 15 years or so to fruit and was probably 25 ft tall. My tree took about 8 years to fruit.
Hawaii has more variety so maybe you can find a grafted tree from there. Or alternatively, maybe someone from Hawaii can mail you some budwood from a good quality variety.
This is a tree that is definitely in need of a dwarf cultivar.
