Sure looks like a softer version of a Purple de Oro. But after a search, the closest match I could find was for a
'Country Melody'. Here's one source: http://www.easytogrowbulbs.com/p-166-daylily-country-melody.aspx

But do a Google search on Country Melody and you may find even closer color matches, and from various sources.

Country Melody (Klehm, 1987)
height 30in (76cm), bloom 5.5in (14.0cm), season M, Dormant, Tetraploid, Fragrant, Pink with soft yellow halo and throat.

Mine is Purple, Sorry (Color off! It's my Camera)
Mid Bloomer 6" Blooms 28" Tall I think it is a Tet though
Don't know if it is Fragrant. And They are all Dormant for me here in Zone 5. I did trade for this 12 years ago, and it was probably old at that time.

Thanks for the Effort! I appreciate it.
