Growing anything in our rather extreme climate can be a challenge. You have my sympathy and my empathy. It's interesting you should mention Carpenter daylillies because I recently talked to two people in wildly divergent climates (far north vs far south) and neither one had had good luck with Carpenters. My own personal experience is varied depending on the daylily. One of my oldest daylilies is a dormant from Carpenter and has survived 10 years (in a pot btw). Another one that comes to mind I've tried 3 times and can't keep it going more then a year. Same with a couple of examples I can think of from Norris. That horrible winter you mention I believe was 2013-2014 and people all over the country lost daylilies that they had had for years (me included)......I would think that plant genetics would play a part in which daylilies do better then others. If a hybridizer continually uses the same group of plants to cross with and they are finicky, then that could account for the continued losses from that group that the hybridizer produced.............Maryl
