I have only had Chaotic Design in the gardens for two years, so I believe it is still becoming well established. But these blooms are stunning!
@touchofsky, yes - I absolutely believe that here in colder gardens, the amount of snow cover is a significant factor in how well Chaotic Design performs.
Our average winter (zone 3, very rural mountains) we get over 360 inches of snow... At any given time, even after winter thaws and constant settling of the snowpack, the gardens are generally under at least 3 to 4 feet of snow cover during a normal winter (snow is a great insulator). I regularly garden with plants hardy to zone 4 that survive well here, and also some that are rated for zone 5.
While dormant daylilies are an obvious choice, I have many SEV and Evergreen daylilies that thrive here. I also mulch (pretty much everything except Bearded Irises).
Chaotic Design has had zero problems here and blooms beautifully here. I would not hesitate to recommend it.
