This year we had a seedling bloom for the first time and realized our tag must have listed the cross incorrectly. Ashton described it as looking very much like Jerry Hyatt. I thought certain it is a Tet. To test we put it's pollen on several other daylilies, both Tet and Dip. Almost all set seed pods. The pods looked good for a few weeks and then the Tets started to abort. We are now sure the seeding is Dip since all the Dip seeds stayed and I harvested the first pod yesterday from Dip seedling plant.
Here's the seedling that we were unsure of.
