Thanks Marcia! THe information is very helpful. I also posted on Facebook and got similar responses. Basically, it really needs a lot of protection to insure its survival through the winter. Some are able to grow it in the ground with heavy mulching in zone 5. As mine is a single fan, I am potting it up and growing it inside until spring. I got mine from a southern grower. There was rust showing on the foliage when I received it. In order to prevent its spread, I had to cut the foliage down to about 2 inches and then sprayed the whole plant with Daconil. I am planning to spray it every 3 days for the next 2 weeks and then once a week after that. It maybe overkill but better be careful than not. As it is a small plant, it does not require that much spray. Given what others have shared about growing it, I need to find the hottest and sunniest location in my yard for it. This is one daylily that likes plenty of sunshine and heat. THen in the winter, I will put heavy coverage of mulch around it.
