I'm in fair oaks California zone 9b, and I successfully grow bananas (blue Java, Orinoco, praying hands, raja puri) guava (red Malaysian, tropical pink,) cattley guavas, avocados (Mexican varieties) white sapote, longan (Kahala and sri champoo) cherimoyas, Yerba mate, ginger, tumeric and galangal, Inga feuilleei (ice cream bean) tamerillos mountian papayas, sugar cane, Inca berry and chayote. Most important things is to utilize overhead canopy for frost protection, many of these species get more adaptable as they get more mature!
