Description

Wilson pawpaw is a hybrid of the American pawpaw in the custard apple family (Annonaceae) and was found growing in the wild in Kentucky. 

It will grow 15 to 20 feet tall and 10 to 15 feet wide in a pyramid-shaped form and needs full sun to partial shade in moist well-drained soil. Wilson requires another variety planted nearby for the best fruit production. 

The brownish-purple flowers appear in spring, followed by edible fruit. The medium to large fruits have a custard texture and a sweet banana-pear flavor.  Fall leaf color is a bright yellow.

Pawpaw does well in naturalized, riparian, or woodland areas. It is a flowering tree that attracts butterflies, pollinators, small mammals, and songbirds, which makes pawpaw a good addition to a butterfly, pollinator, or rain garden. It is an easy-to-grow fruit tree for children's gardens

Quick ID Hints: 

  • Leaves produce a distinctive odor when crushed (similar to green bell peppers).
  • Leaves large, alternate and distichous; they turn yellow in fall. 
  • Bark is smooth with wart-like lenticels

Insects, Diseases, and Other Plant Problems: No significant problems. The pawpaw peduncle borer (Talponia plummeriana) is a small moth whose larvae burrow into flower stalks. They can destroy large numbers of flowers. This pest is in NC. The zebra swallowtail butterfly larvae feed on young leaves, but they seldom do permanent damage, nor do they affect fruit yield. Trees can produce root suckers, which can be troublesome in the landscape.
