Penstemon osterhoutii
Osterhout penstemon is a small herbaceous perennial of the plantain family, native only to northwestern Colorado, grown for its sky-blue to violet funnel-shaped flowers. It needs sun, good drainage and dry conditions similar to its mountain habitat.
Penstemon osterhoutii, commonly called Osterhout penstemon, is an herbaceous perennial of the veronica family that is only found in the state of Colorado in the western United States.
The Osterhout penstemon is endemic to northwestern Colorado. There is grows in Routt, Grand, Rio Blanco, Garfield, Eagle, Summit, and Pitkin counties. In the past some collections of thickleaf penstemons (Penstemon pachyphyllus var. pachyphyllus) from the eastern Uinta Basin were mistakenly identified as Osterhout penstemons.
