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).
