I've done it. It works well, though I don't know if it was because of my climate, or what? But the seedlings I started this way took five years to bloom, where the ones I started indoors only took three. Seedlings don't bloom very fast here no matter how I start them for some reason? Five years just seemed a little too long though. I'd say try it anyway, at least with some of your seeds. They will come up and may bloom sooner in your climate than they do in mine. Our typical season here doesn't normally see a lot of heat, and this may be the reason they are so slow to bloom. Daylilies love warmth.
