Nectaplums, never heard of that cross, sounds really good though. For growing, it depends, the problem with with tropical climates (I'm in South Florida) the humidity brings a lot of fungus growth to fruit trees, and citrus is "controlled". I tried regular plums and peaches years ago, they did "ok", but the growth was stunted and I eventually removed them due to fungus. I don't have any space in the house I live in now, but someday I will get to a place where I can grow more.
