A lot of daylilies have some degree of diamond dusting; the ones that really stand out, though, are absolutely coated with it.
I was looking at four of my seedlings yesterday (not hybrizing for diamond dusting but for hopefully polymerous daylilies), and at least 3 of the 4 had light diamond dusting. (The 4th appeared to have it in the yellow throat, not so much on red surface.) But all of those were
lightly diamond dusted... you had to look at the blooms closely. What I would like to see are daylilies that are just dripping with the bling, so to speak... massive diamond dusting on the tepals, and then having a sparkly gilt edge to finish it off.
Here is one of the seedlings, image taken around 12:33 pm (after I had saved the pollen). If you click on the thumbnail and look at the 12 o'clock petal, you can clearly see the diamond dusting, and a hint of a gilt edge, as well as the diamond dusting on the adjacent seedling. (This is the maiden bloom season on this seedling. Sadly, it looks like it has a lot of faults, but I will probably keep it to work with...)
