This won't answer your question but... A few years ago before I discovered winter sowing I found an article on starting daylilies from seed. It said to throw some Perlite in a ziploc bag, add just enough water so the Perlite was damp, not wet, toss in the seeds and set the bag in a sunny window. I followed the instructions and, sure enough, 14 days later I had 12 two-inch daylily sprouts--100% germination from the 12 seeds I sowed. I potted them up to grow on, they went dormant in the fall, came up again the following spring. I finally potted them in gallon pots; one plant bloomed last summer.

As mentioned above daylilies grow very easy from seed. Just what ever you use for everything else. I have not got any to bloom before year three, but I don't have as much sun as they like. Al
