- Description
-
Pawpaw, is a native, understory deciduous tree in the Annonaceae family. It typically appears in a cluster in alluvial, or other moist, nutrient-rich forests. The cultivar, 'Allegheny', is noted for its vigorous growth and large fruit that can weigh in at 8 ozs with sweet, early-ripening, creamy yellow flesh.
Plant in average moist, well-drained soils in a mostly sunny location. They will tolerate some shade but will produce less fruit. Mulching the soil will keep the roots cool and moist and regular fertilization will result in the best fruit set. They will grow quickly to 20 feet tall and wide. Pruning the trees to a height of 10 to 12 feet and removing suckers will keep them at a manageable size for harvesting fruits.
The large green leaves lend to a tropical feel and the bark is smooth with wart-like lenticels. The burgundy flowers that appear in spring are not particularly showy and are pollinated by flies and hence have an unpleasant odor. 'Allegeny' produces a sweet edible fruit that matures earlier than other pawpaws in late summer. To obtain cross pollination, plant more than one genetically different pawpaw within 15 feet of each other. Hand pollination can lead to heavy fruit set.
Wildlife eagerly seek out the fruits and often beat humans to the harvest.
Insects, Diseases, and Other Plant Problems: No known disease or insect issues. The pawpaw tree produces self-defensive compounds so that insect pests are usually not a problem.

- Life Cycle:
- Woody
- Distribution:
- Washington south to New Mexico, Nebraska, Iowa. Parts of Wisconsin, Michigan east to Maine, south to North Carolina and Florida.
- Fire Risk Rating:

- Wildlife Value:
- Flowers are pollinated by flies and beetles. Edible flesh fruit eaten by songbirds, wild turkeys, squirrels, raccoons, opossums, black bear, and foxes. This plant supports Zebra Swallowtail (Eurytides marcellus) larvae.
- Particularly Resistant To (Insects/Diseases/Other Problems):
- Resistant to fire. Moderately resistant to deer damage. Heat tolerant.
- Edibility:
- Allegheny pawpaw is a early ripening heavy bearing tree that produces creamy sweet small fruit. Thinning would help to bar larger fruit. Mature fruits have a banana custard with a hint of citrus flavor. Raw berries can be eaten in small quantities but can cause stomach/skin irritation in some people.
