I think some of them are also buyers that do not have access to the plants due to phyto rules. Buying seeds is really the only way to get at some of the genetics. But yes, I saw the Tet HAI listing earlier today. I was floored. Though I am sure people would be surprised at some of the things I opt to spend my money on. Besides daylilies of course!
I too will vouch for Rich's seeds. I have several that are growing up right now and 6 of the 7 were up within days.
