That is quite the list of requirements. Loquat would probably be great for your area and is a highly valued fruit in other countries that is ornamental, adaptable, and resistant to many Florida pests. The main issues would be fire blight (often linked to over fertilization) and fruit flies (which tend to be more problematic the further south you go in the state). Other fruits that you might consider are pomegranite, muscadine grape, persimmon, fig, select avocado varieties, and possibly white sapote. I have not tasted white sapote, but Wayne Cliffton spoke highly of it and gave us a Smathers before he passed away.
Well they’re not all necessarily requirements what I stated in the original post, but more as a guideline..
yeah loquats do just fine here, almost no problems. I guess sourcing the better varieties more cheaply is the biggest concern..
I have had problems with fire blight but normally just on pears.. Floridahome btw is quite resistant..
Pomegranates- they grow easy with almost no irrigation and root up easily from cuttings, But I heard only certain varieties fruit very well in Florida.. and I don’t think I have those varieties as of yet..
Muscadines/scuppernongs- very adapted and most bear well, just seedy
I have most of the cold hardy avocados..
I am experimenting with a white sapote, bout a year old in the ground. Not sure what variety.. I haven’t tasted it either lol
