I have plenty of small rollinia seedlings I could give you (one or two haven't even opened up their first true leaves yet, the biggest have maybe five leaves or so, about 10-15 total), but I doubt I could mail them to you and get past customs. Hmm. Coming to Iceland any time soon?
I don't have atemoya seeds or seedlings. I do have sugar apples seeds onhand, though (still in a fruit ripening on my counter).
