You-Pick at Red Fern Farm for 2018 | Red Fern Farm
Some of their varieties off the top of my head: NC-1, Susquehana, Shenandoah, Overleese, Atria, Betria, Regulus, Pennsylvania Golden #1, Pennsylvania Golden #2.
Atria, Betria, and Regulus are their own selections and are every bit as wonderful as Peterson’s pawpaws.
