You seem to forget that I only purchase daylilies that are grown and hybridized in FL. In THIS climate, there are distinct difference in foliage growth in winter months between evergreens and dormants. I don't know what happens in Canada but have strong suspicion that your brutal climate would send any daylily underground during the winter--or at least as far underground as they can go. Down here, the winters are mild. Although we can get cold, it doesn't last very long. It is not difficult at all in January to look at a garden and to point out which plants have dormant traits and which have evergreen traits. In my experience, the evergreens continue to stand tall, put on fans and generally look very good. Daylilies with dormancy in them will shrink down to 3-4" high and stay that way until late in March. They may add fans, but they will not bloom as early as evergreens because they have to come out of their funk, grow and then bloom.
