Selves (selfs?) are one of my favorites in daylilies. They will NEVER grow old to me.
It is really nice to have all kinds of extras, but they often need to be viewed up close and personal.
Selves are great garden plants. They can be viewed as a garden color. Patches of color even. I often mass plant (7-12 clumps) together along with mass plantings of grasses or other plants such as Rudbeckia 'Goldstrum'.
SOLID ROCKS!
Curt Hansen mentioned above does lots of SOLIDS - and lots with NO RIBS.
And to answer above, yes, one with a white ribs is still considered a Self!
All of the Lachman's daylilies are nice. My favorites would be red JOHN PHILIP SOUSA and white ribbed late PINK DAZZLER
