Sub Tropical Fruit Tree Varieties

HI All!

So, I'm researching which fruit trees grow well in Buenos Aires and , apart from the usual suspects, of figs, citrus, peaches, plumbs, pears etc, I'm specifically looking for sub tropical (or cold resistant tropical) lesser known regional fruit bearing trees.

If anyone here has grown any and has experience with this, I'd love to find out how things went as I will be trying soon!

Pitanga, cerella, guayabo , jaboticaba for example...
