Good decision, jnocholes- and I speak as someone with experience at trying weird things to grow before knowing if I'd even eat them.
I wrote about pawpaw for daves garden- but doubt all the links are still good.
This site seemed pretty good then

A lot of cited articles have very old dates. I wonder if that was somebody's pet project for a while, but that person has moved on or lost funding. After my research, I felt they were too challenged for my yard. Wild pawpaw are very common around me near rivers. I still never catch them in season- only seen them once on the ground. Flowers are fun though.
