Comments: Pawpaws are from a family with a rich history of tropical fruits. Pawpaws are the only fruit from this family with a temperate range. The fruit is a prized edible and tastes like a thick custard.  The fruit does contain a chemical called annonacin, which is neurotoxic at very high doses (Potts et al. 2012).  On the other side, a study (Brannan et al 2015) found pawpaws to be a good source of phenolics in one's diet.

How to eat: When the fruit is soft but not mushy, cut it in half, remove the seeds and squeeze or scoop out the delicious pulp.

Etymology: The word, triloba, is Latin for, "having three loves".  

 

Butterfly & moth host plant:  Pawpaws are the larvae host plant for the Pawpaw sphinx (Dolba hyloeus) and the Zebra Swallowtail (Eurytides marcellus).

Landscape: 

Pawpaws are a great fruiting tree for Northwest Indiana native gardeners. Because the flowers need to be cross pollinated with another individual to produce fruits, you may think of planting two pawpaws to get fruit. It prefers filtered shade so if you have a large understory that needs some more shrubs, think about planting a pawpaw.
