I got 4 of them from Adam at Perry Pawpaws, and the other 6 from Jonathan at Footmore Farms.
Adam ships and has some specific cultivars (that I don't know enough about to know which ones are actually like.... any different or different enough). Perry's came in as basically twigs, and they leaved out with big, beautiful leaves in the house, but when I moved them outside onto the front porch (mostly shaded) they absolutely hated it. It was also a bit of a runaround with Perry Pawpaws- I ordered them, but the website lets you pick up or ship, and it glitched to pick up for me. When I called to correct and pay shipping, he took a Venmo payment from my mom, marked the order complete and.... didn't mail the saplings. I had a hard time getting back in touch, but when I did, he finally did correct it and send the saplings
Footmore Farms won't ship or hold, but the saplings were outside when I picked them up, and although they're the same height or so, they have a LOT more leaves and look a lot healthier post-planting. The leaves are a big smaller, but they're thicker and hardier looking, so I suspect that they were grown outside from the start. I've read that it makes a difference; that letting them grow their first leaves outsides in the sun makes them more sun tolerant as saplings, otherwise they need shade. I have a lot more confidence in their success.
So, if you CAN pick up from Cedar Springs, MI, I would definitely recommend Footmore Farms first, OR figure out how to grow them outside for their first leaves if you go with Perry Pawpaws. When I was there Thursday, Footmore had maybe 6-8 more Pawpaw saplings left, because it's like, a guy growing plants in his yard in BFE.
