I have had this daylily for many years and will always have it in my garden. It is a wonderful bloomer and great performer. Have really never had any trouble with it. I guess if I were to find anything negative it would be that I like scape height to be taller. It is fertile but I have found that it does not produce a great deal of seed. My one and only seedling that I got from Flutterbye was awesome and I ended up registering it.
This is Jester's Collar (Black Plush x Flutterbye)
