New Leaf flipped the script on native fruit. Now your native fruit and only your native fruit has a chance of becoming perfect fruit, which you can plant to grow trees that grow perfect fruits. Perfect fruits are shinier and different colors than regular fruits.
native fruits sell for 100
tropical fruits sell for 250
non-native fruits sell for 500
native perfect fruits sell for 600
non-native perfect fruits sell for 3000
best way to make money with fruit is to grow a bunch of perfect fruit and take them to someone else's village to sell for 3000 a piece. You can't grow non-native perfect fruits in your own town.
Here you can see regular and perfect versions of every native fruit:
Aesthetically normally I prefer cherries, but perfect apples take the cake imo.
