I believe Deryll said that to let Dianne know that he used to have one she wanted but does not now have it. Deryll, you can clarify. Did you mean to suggest Oakes was selling tissue-cultured daylilies?
I would be astonished if they were. The plants I've gotten from them have always been large (clump-size) and very healthy. The flowers always look like what I was expecting. Oakes does have some issues (overcharging is one of them), but I can't believe their plants are tissue-cultured.
