Well, I lost about half of the cultivars I wanted to list to the requirement of 3 others saying they own it, and that's too bad. I have almost 800 cultivars, and I've never indicated that I own any -- sorry, but I'm just not into making plant lists here in ATP. But I did find quite a few that had at least three others who indicated they had them.

I did this all at once so I don't have to do it again, so maybe you can break them up into batches of ten.
Maybe at some point in the future more newer varieties could be considered even if they don't show the required three owners. I think that could also be very informative.
