I'm seeing that they need to be cold stratified. Lots of advice on doing that, but this article is about Pawpaws. https://www.kysu.edu/academics/college-acs/school-of-ace/pawpaw/pawpaw-planting-guide.php#:~:text=To%20break%20dormancy%2C%20the%20seed,late%20July%20to%20late%20August.

I have some pawpaw seeds that I’m trying to germinate. I cold stratified the seeds (perhaps too long but they didn’t dry out) but they are not sprouting. I put them in Solo cups with potting soil and put them under grow lights.

Did you have any luck germinating the pawpaw seeds?
