Penstemon strictus (Rocky Mountain Beardtongue) with its spikes of bright blue flowers and evergreen foliage, is one of the easiest-to-grow Penstemon. Long-lived, this beauty thrives in most any well-drained soil with full sun exposure. Drought resistant/drought tolerant plant (xeric).

Description

24″ tall x 36″ wide (seed propagated). A native beardtongue of the foothills and mountains of the southern Rockies, this plant grows easily over a wide range of the western U.S. The tall showy spikes of intense blue-purple flowers last for over a month in late spring. Spreading steadily via stolons to form large clumps, Penstemon strictus is one of the longest-lived, most easily grown of the Penstemons. A real show stopper! Cut off flowering spikes after bloom; leave a few if reseeding is desirable.
