I have either a "Lorito" or Viejo" (been a while since I looked at the tag) growing in a large plastic tub in my yard.
Probably had it about 6 years, it has set fruits the last 2 years, but either dropped them all or they got knocked off.
Couple of cold snaps have set it back, and I probably neglected it to much.
I recently relocated it in the yard, so it is more visible, and gets better attention, I also have the tub sitting in a small kiddie wading pool so it gets watered better.
Heard it takes over a year from flower to fruit harvest (13 to 24 months according to UF/IFAS), so that could extend thru 2 seasons of cold.

Every once in a while I see trees for sale at Home Depot. Rockledge Gardens might have it, Green's Nursery in Apopka has them on their availability list.
