I'm not sure if this helps but I know that when Holly Hill Daylily Farm closed the owner donated leftover plants to various organizations in NC. One of them was the NC Botanical Gardens in Chapel Hill. I'm not sure how many he gave them but I saw at least 1 of his introductions there. They may have a list of all the daylilies he donated. I'm sure someone there would be willing to take pictures if they don't have any already.
I have 4 of his introductions but I'm hesitant to send my photos since the plants are in NY. The colors aren't the same up here (more washed out) so they aren't really representative. Most of the pictures I took at the farm are pretty awful since I was just using them to remember which ones I wanted to buy.
