I live on the border of zone 3 and zone 4. I am a second generation daylily grower! Temperatures here get to -30 and occasionally -40 with deep snow cover (we still have several feet now : Apr.3) Indy Charmer does well, blooms well and is increasing well. It is however planted against the west side of the house. I will be testing it out in the open garden, but I have a feeling it will do fine.
