Julie, I grow Alan Lane Agin here in east-central Georgia and it is a true "dormant" for me, losing all of its leaves and staying underground from November until at least February. Then the blue-green foliage begins to appear, but then it seems to hesitate until temperatures warm a little more before starting to really take off. Interestingly, many of its seedlings show similar "dormant" tendencies even when crossed with an evergreen or a semi-evergreen.
However, Venus Flytrap which is registered as a dormant never loses its leaves here during the winter and basically stays green all year. I have seen others express the same behavior with this cultivar.
One last comment - - I have two mature (7+ years) seedling siblings from the cross Leslie Renee X Cerise Masterpiece, both of which are registered as semi-evergreen. Both of these parent cultivars have dormancy in their parents. One of my seedlings is an evergreen and the other is a dormant. In fact, the dormant seedling is the very last daylily in my garden to make an appearance every spring though some of my cultivars that are registered as "dormant" appear earlier but bloom well after that seedling. That kind of thing makes tetraploid genetics a complete mystery to me. Oh, by the way, Shores of Time is a sibling of Leslie Renee and although it is registered as a dormant has never lost its leaves during the 9 winters it has lived in my garden including a couple that actually reached the mid-teens in temperature.
