Those trees do sound interesting. Let us know how it goes with them.
I'm just starting to get into trees. A permanent location helps. I have 2 granny smith apple seed trees. One bloomed last year. No fruit. Still waiting for my citrus. Who knows what they will be. I can say they were seeds from Navel orange, lemon, grapefruit and kumquats.
Don't really have any dedicated photos of the plants, sorry.
I can say, if I put them all in the same place, they take up a 12' X 12' room. I'm in the planning process for a greenhouse. My plumeria and banana will like that.
I'll post some pix in the near future.\
