"In the near term---one might use a clarifier and see if that helps. Pat Stamile used Great White to clarify his pink line. It also helped to make his whites---whiter. I think his Michael Miller has a similar ability--but not as consistent---as Great White. A clarifier may clean up the background to make the dots more distinct. Then again--it may eliminate the dots altogether. It's worth a try."
The problem with using those two cultivars, is that they are both rust susceptible.
We do not need more rusty daylilies. Certainly there must be something suitable color-wise, which will clarify, and has some rust resistance... or at least doesn't score a 3.8 ('Great White') on the rust scale!
