I have seeds of a variety of self-fertile cherimoya that is sold by a fruit nursery in Australia. Freshly harvested. I can't guarantee it will be self-fertile in all regions, but it is a good sign that it requires absolutely no hand pollination in my temperate Australian climate and I have only one tree.
I'd like to trade for seeds of: eugenia selloi (syn. neonitida), eugenia itaguahiensis and eugenia calycina (when in season).
