Paw Paw here is not a tree, it is a low shrubby plant,
Asimina augustifolia or Slimleaf Pawpaw, often called
Dog Banana and attractive to critters.
Green fruit of Pawpaw
Asimina augustifolia is the host plant for the larva of Zebra Swallowtails.
Zebras always nectar on yellow and lavendar Lantana near the Dog Banana.
I am linking to Outlaw Gardener's Post on Paw Paws. He asked about readers who know and grow Pawpaws. His are not the same as mine. These are native to the southeastern US, growing scattered along woods edge, not in a cultivated patch.
