He keeps the names shown on his website even when they are sold out (told me in email).
I see some I have overlooked like Kasandra, F-26, L-93, but I’m not sure which have a good chance of completing edible fruit in Zone 4b. He has Rosseyanka but I think it harvests last week of October which in Minneapolis only works in rare years like 2024. It snowed 12" on Oct 21 in 2020.
Before this thread I had overlooked Campbell NC10 due to lack of reviews or suppliers. Its origin is actually sheltered in winter to Zone 6 but it’s at a northern latitude so the ripening time could work.
Here’s Kasandra ripening on October 6 in mid Tennessee, but their growing season starts like 21 days earlier than Minneapolis:
