Prunus serotina, black cherry, is native to some parts of florida, but I
wouldnt try to grow them any farther south than zone 9(south of lake okechobee,
to make it easier) As for the commercially available fruiting types, sweet
cherries will do okay in zone 8(northern florida and the panhandle). Try and
get them from semi locally available sources and they will probably perform
better for you. Hope this helps!
