Thanks for the information Arlene, I always had the impression daylilies would thrive anywhere in Florida, never to old to learn. I guess I got the idea from visiting the big growers, none were close to the coast and the daylilies were always so large.
I think all of Stamile daylilies came from dormant's because he moved south from New York. It doesn't surprise me that he got evergreens years later because each parent has about five generations of genes to work with and he was using ev with those dormant's because most of what he brought from NY did not do well in Florida. I have crossed two evergreens and got some dormant seedlings.
