I can imagine back in the early 90s I could have had some hard dormant seedlings, but not in recent years. I have only registered one soft dormant and the rest have been simi-evergreen or evergreen.
I have done no research or experiments, but have observed what happens here over the past twenty five years. Sometimes its hard to comprehend what happens to plants in different parts of the world. I believe the modern daylily is so much different than those Stout and others had to work with that they may get different results if the same studies were done today.
