Welcome mcash70! Stick around and you will see lots of pictures and learn a lot about daylilies! There will be more features added to this cubit as time goes by and Dave adds more options.
I had to go online and look at a few more pics of Catherine Woodbury to be sure.... but I think it would be a bitone. Childs did register it as an orchid self.... so...?
From the AHS Online Dictionary
"SELF, COMPLETE SELF:
A flower having perianth segments all of the same color. The throat region can be a different color. In a complete self the segments, throat, pistil and stamens will all be the same color. Also see: Perianth segments, pistil, stamen, throat."
BITONE:
A flower with inner and outer segments of different tints of the same basic color. A bitone has lighter outer segments (sepals) and darker inner segments (petals). A REVERSE BITONE has the darker tones on its outer ring (sepals) and lighter coloration on the inner segments (petals)
Nice pic of Hush Little Baby! I like that flower, but it was not happy here. Neither was Neal Berrey, one of it's parents. About a thousand years ago, I grew the other parent, Trade-Last, and it did well here.
