I'll bet testing seedlings in different areas is extremely variable. Gossard probably would have no trouble getting someone to grow a seedling he wanted tested, but Aunt Edna Mae down the street has a couple of dozen that she really likes and probably no one has any more room to test them. She ends up introducing those she really, really likes based on how they've done for her (and a couple of relatives and friends) with no further testing. Even with someone like Gossard, I expect most of the testing is done by other expert growers/hybridizers. Since even common daylilies aren't commonly seen growing in my area it may be moot for me either way. Just guessing and not criticizing here.
