I have been fortunate in that most have been correct. I have had a few that were not. Two that were incorrect I unfortunately could not remember who I had bout it from (I keep better records now). The last time the seller actually comtacted me before it was shipped to tell me that her historic daylily that she had had for years might not be what she thought it was and asked me if I still wanted her to ship it or did I want me money back. I said to go ahead and ship as I had wanted it for the flower. She did ship it and gave me a choice of other plants she had that were in the same price range as a bonus replacement.
I chose Condilla which I had seen on her web site and loved.
Can't find a photo from my garden but have a few I took at the AHS Region 14 meeting in 2011
I have found sellers very responsive to replacing incorrect plants.
Mary Jane Meadows (Bubbles) sent me a replacement plant several years after it was in my garden once it was discovered to be the wrong one. (I got to keep the other one too, which was a similar flower so all was well.)
