I have several seedlings that have a bit (not wide) of that glitter on the edges, but lovely as it is (and sucker though I am for diamond dusting and all things sparkly), if the seedling doesn't also have the bud count and branching, or if the bloom doesn't open well or can't hack our cold nights, or if the plant is rusty, then out it goes. (I *might* cross it with something else that has the desirable plant traits that are lacking, but I have limited seedling space and other crosses take priority.)
But I have to agree that a daylily that otherwise has good (my definition of "good", maybe not yours) plant traits, AND has a wide glitter edge (and diamond dusting, and a clear colored bloom).... yowza, that would get my attention (and $).
