I haven't mentioned Orotina even though it is well known for fruits in CR. Gary Zill's project is in that area but is about the only place, in my experience, that has much in rare fruits there. There are lots of mangoes, citrus, etc. but not much that you wouldn't see in FL. Orotina gets a nasty dry wind that is a major limiting factor for so many Equatorial fruits.
Actually, in the Dominical area there is no dry wind and a lot of rare fruits have been planted and there is durian production as well as lansium, baccaurea, lots of stuff.
