There were a couple of daylilies in the garden when I bought this house in 2016. I haven't been able to identify them. They must be older varieties gives there simpler forms. The first one has a distinctive wide glowing yellow throat and pale pink/peach petals. The second one is an orange self with narrow petals. I thought maybe it could be 'Orangeman, but I'm not sure.
These put me in mind of the offerings from Olallie gardens, especially the first one, which tend to be plain and simple. Browsing their Web site might help you and they might recognize them of you send them photos.
