I never got why daylilies (Stella or otherwise) are (or were) used in large plantings for commercial landscaping.... The blooms close after one day, and for the most part, in order for the planting to look good, the dead blooms need to be deadheaded. Who's going to do that job?
Getting back on topic, I find it curious that the "color disasters" here frequently mention pink and yellow. I was looking at one bed this morning (which has had some deer depredation, sigh), and most of the daylilies in that bed are in shades of lavender, pink, or melon. There is one yellow daylily in there, moved last year next to 'Elizabeth Salter', and it struck me that it looks out of place. I suppose that I'll have to move it, though I am not sure where to. (Sorry, no pictures.)
(In that same bed I also have three 'Flower Carpet Amber' roses. They are offset behind the row of daylilies, though, and the roses themselves are a color blend of soft yellow and peach tones, so they fit in the bed better, colorwise, than the yellow daylily.)
