no funny stories - my story is ... ahh... underhanded. I did have someone try to switching tags from a cheap one to an expensive one. Like I did not know what was planted where. I soon learned to take the blooms off the expensive ones on open garden days. I've even been known to switch out the permanent tags I use now when I have to leave home during bloom. Without blooms, that new expensive one looks just like the $10 name tag I would put on it. And, if Jack the Digger comes and digs up what he THINKS is the expensive one, I'll have the last laugh when it blooms in their garden.
And, then the time someone came while I was at work, without calling, and my Mom sold them a clump of a $100 daylily for $15. She let them dig it and they destroyed the roots on the neighboring daylilies getting the one that they wanted. She had no clue who they were either. I could have KILLED her. After that, I stopped having open garden here, and also stopped selling from my home.
I think the one comment that always got me was... you have the "gardener" come who has little to no experience with daylilies. They see a bloom on a new, expensive intro. The comment "oh, I have that one already."
