Asimina triloba
Michigan Native: Yes
 
This tree produces big, almost tropical fruit that taste like a cross between a banana and a mango. It's North America's largest native fruit! 
 
For best results, buy at least five trees that are not the same sex for pollination. Pawpaw trees will not pollinate themselves, and the flies and beetles tasked with the job can be unreliable, but trees of different sexes and varietals will pollinate each other.
