We grow lots of herbs successfully, fruit trees seem to work well (wild and planted ones) but I have had limited success with veges.
I've grown many from heritage seedlings that I painstakingly nurture (rats and bandicoots are a problem), some with success, others, well pathetic.
Some of the more unusual crops I have had success with include rhubarb, ginger, galangal, lemongrass, tomatoes (all year round), garlic, chillis (OMG - chillis everywhere), asparagus, strawberries, did I mention tomatoes and heaps of different kinds of herbs.
