I guess we'll find out together then because I bought one back a few weeks ago & it's already planted out where it will get no pity from the elements. Did you Google it to verify its hardiness zone? I wouldn't have planted it unless it was hardy at least to zone 5. The one I bought didn't have a tag so I just matched up the flower to one I found on Google.

there is gazillions of various penstemons but only few do well in my area, even fewer in my shade

The label says it's hardy to zone 8, but I was totally in denial when I bought it. I thought, 'that tag can't be right, maybe they made a mistake.' I guess not. That should teach me, right? I should only be wintersowing and not wasting my hard earned $.
