I have a rapidly spreading pawpaw patch in Massachusetts. I live in a wet area and they are thriving to the point that I need to cull new trees that are invading my other gardens. I have taken to selling the fruit and surplus seedlings on Craigslist. 2022 was a bumper crop but a late frost in 2023 killed many of the flowers and I barely harvested a bushel of fruit. I believe that the shifting climate has made this area nearly ideal for them to spread naturally.
