Penstemon payettensis is a very showy plant from northeastern Oregon to central Idaho. It’s usually found between 2000 to 2700 meters elevation along roadsides, on gravelly slopes and in open woodlands. The name is derived from Payette National Forest in Idaho. The stems are up to 0.75 m (ca. 28 inches). Although very showy in the wild, it may not live a long time in the garden. It would be worth the show while it lasts, though.

This is currently classified as subgenus Habroanthus sect. Glabri.  This is one of the penstemons from which I’ve scared masarid wasps out of in the morning.
