The native fruits are-
Apples
pears
peaches
cherries
oranges
You have one fruit out of these which grow in your town. To get other fruits, you need to link with other players and get fruits from them. You can also get these fruits from tours in the island, however, they are cheaper to sell. Also, there are some perfect fruits in the game too. In the beginning, you get one perfect fruit in your town. If the perfect fruits you grow in your town are your native fruits too, the tree gives you perfect fruits.
