Growing paw Paw's from seed

I found a paw paw tree last year and saved some seeds from the ripe fruit. I've kept them in the freezer since I know here in VA they would freeze over the winter. (First off, are they still viable? I collected them in fall of 2018.) Are there any rules for planting them or tips I should know? I figured it would be good to add the genetic variation from the seeds. Are there any reasons not to grow from seed? (Other than time to fruiting) I would appreciate any and all help, thank you!

This is a great question! I wish someone could answer it for you! I would love to know, as a friend has them on her property - so I may be able to get seeds from her this Autumn!

Yea they should be fine. They take a lot of patience, they take a while to sprout. I have some cuttings going and a bunch of seeds planted this year. I'm going to transplant them in the woods when they get about a foot or two.
