Thank you, Tabassam, for the correct photo of Rudolf.

(Edit dated 05-29-07. For some odd reason, Tab's
image is now missing and does not show in her
'images uploaded' file. I will update with a correct
photo of Rudolf Seyer in just a few moments)

For some odd reason, I cannot locate my photo of
Rudolf Sayer anywhere, so this summer I'll take and
upload another one.

Rudolf is just adorable. It's tiny blooms are
a beautiful dark shade of a color fighting between
red and maroon. Gorgeous!

One of the problems with this daylily is that it is
often incorrectly spelled, thus making location
