I know that peaches arnt local but they have a good lead into fall from gerogia, florida grapes can be foraged and cocoplums too.
figs come back in season in late november but they are not local. sorry thats all i got.
lol i moved away from boynton years ago I remember Boys market good eats there.
All i remember ever being local was some strawberry farms down in miami i duno if they are still around and people who might have grapefruit or orange trees and of course avocados tho there not high carb. I had a friend who had a farm down there years ago that grew some vegatables.
I'm north now in pa and as soon as spring hits it seems like we go from one abundant fruit to the next then we have our dry spell in the winter.
I hope you guys like it down there. I despised the place and glad I moved. But it does have its good points i guess.
oh and well yeah years ago you could drive down 441 boyton on north and hit some farm stands those are all gone as well if i recall last i was there I didnt see anything like that.
