My first year wintersowing was a bust too. Last year I only got 3 daylilies to sprout. This year is better but not even half of my containers are doing anything. So far I have salpiglossis, phlox paniculata, Lilium regale and daylilies up. I didn't really ws anything from the swap since I had seeds from a swap I did in 2014 that I'd never sowed. So don't give up! Some years are better than others I guess.
