I previously asked whether penstemen is poisonous to dogs. Answers posted referred me to the excellent ASPCA reference, which I actually had already checked prior to posting my question. I posted the question because neither their "poisonous" nor "non-poisonous" list includes penstemen. I'll continue to check with other animal poison control sites and monitor this Gardening website to see if anyone else has other ideas,.
