Not sure if this is a match to your daylily, but I did an advanced search in the AHS database with these parameters: Tet under 28", single, pink, with description "teeth" and not registered after 2010. There was a thumbnail pic of Helene de Troie, but when I click on the entry, there is no larger picture and I can't find any other reference.
