It is a nectar plant for a lot of other insects and also is important for small mammals and birds.

Pawpaw grows best in places that have well-drained acidic soil with partial shade.  It ranges from the midwest to eastern North America.

The Annonaceae is a tropical family of plants and the pawpaw is the northernmost growing representative of it.  The name comes from the Arawaken name for Papaya, a tropical fruit (Lady Bird Johnson Wildflower Center).  The genus name is a Latinized version of the French name of the Indian name (MO Botanical Garden).
