Hi! I raise and sell about nine varieties of sunchokes including all the ones you've named here. I don't think you have any red fusueau among the ones you've photographed. The link on norton naturals looks like the red fuseau I know and love, although this year some of mine grew in pale! So weird. But such a truly lovely variety. Yes, the second photo -- the one from Ireland is also red fuseau. Not Aurora Rubin. I know this is just two tubers, but here's Aurora Rubin.

The Pink Crispy (photo 4) is accurate, at least it looks just like the pink crispy variety I raise. They are long, sometimes VERY long and great -- smooth, tasty, hardy, pretty. Wonderful.
I think the first one you have might be beaver valley purple. Not 100% sure on that, but it's definitely not Red Fuseau.
The second photo looks identical to another wonderful variety I grow called Red Rover. Those are so productive and such cute little jewels!
The third one I'm not sure, but I wish I had it. It looks nothing like the Pink Crispy that I have.
Let me know if you want more named varieties or want to swap!
