It depends on where you live! For us, living in South Florida, exotic fruits are just lesser-known tropical fruits. Think about it, fruits such as bananas pineapples, limes, papayas, mangoes and oranges to name a few, are fruits that grow in tropical climates but are pretty common and we are very familiar with them. When it comes to exotics, they grow in the same areas in general but are not as well-known such as Sourspo, Lychees, Mangosteens, Mameys, Dragon Fruits, Bread Fruit, Guavas, Passion Fruit just to name a few are really tropical fruits that are made "exotic" just because their limited availability and limited demand in the United States since many people are just not familiar with them. So? What's an exotic fruit? It's just a tropical fruit that's not as common.
