Penstemon

This Penstemon has been found as a garden escape in Norway recently. Anybody who knows which one it is?

Hi, Trond,
It looks to me like Penstemon smallii (or some colour selection therof)... one I've never been able to grow here.  If so, it's native to eastern Tennessee, western North Carolina and NW South Carolina, according to Robert Nold's Penstemons.
I suppose, if it can survive in your very wet climate, it might make sense that it would be likely to be one of the eastern species, that can take more water, humidity, and heavier soils.

Can anyone else comment?
