Searching for Fleener's topset onion -- can share other named varieties!

Hello friends, I'm growing on a small plot of land in Northern Colorado. It's a mixed planting scene, but with a specialization on two weird perennial crop varieties: helianthus tuberosus aka sunchokes or Jerusalem artichokes (16 named varieties this year!) and perennial onions.

So far I have catawissa white and red moritz. I know that somewhere out there is a variety called Fleener's topset onion. Anyone grow that variety? I'd be happy to buy some from you or trade for a variety that I have!

(Meanwhile, if you don't have any, but would like to grow catawissa white or red moritz, or sunchokes, I have them posted online. Send me a message for more info!)

I grew them about 10 years ago. I don’t believe they were top setting onions though. They were a multiplier that produced small pointed onions. Mine died out after the second season. I’ve never been able to find them again. However, I would consider them similar to the Shirley Hammond multiplier or what most would call a winter onion in the south. Etsy might be a source for you.

Thank you! I will try a search for that variety. I appreciate the tip!
