Hi Mad, I have a number of volunteer penstemon plants at the end of my driveway that blew or washed in from somewhere. They are a med. blue and have bloomed for several years. I have planned for a while to move them into a bed somewhere else.

Not much help as I don't know what variety they are. Could be native or from someone else's yard. I'm on downhill terrain so I get a lot of garden gifts--some quite amazing! I will save you some seed this year if you like.

I sent you a PM.
