The Pawpaw tree, or Asimina triloba, is a small understory tree native to the Eastern United States. Pawpaw trees typically grow in shaded locations in bottomlands or along stream beds. Leaves are large and have a tropical look. Interesting purple flowers bloom in spring and are followed by small to large green, edible fruits if pollinated. Fruits have a flavor and texture reminiscent of bananas. Trees will sucker readily, forming thickets. Pawpaws must be pollinated by a separate tree. Best grown in full sun to part shade with ample moisture. Host plant for the zebra swallowtail butterfly.
