What's in a name?
Found throughout the eastern United States, with its most western limit reaching southeastern Nebraska. Asimina triloba is commonly known as: Pawpaw, Common Pawpaw, Custard Apple, Indiana Banana, West Virginia Banana, and Wild Banana.

The Common Pawpaw name comes from the Arawakan name, papaya, although the papaya is an unrelated, separate tropical fruit. The genus name Asimina stems from Native “assimin”, and triloba is in relation to the blossoms' petals which resemble a tricorn hat.
