Showy penstemon

Penstemon spectabilis


The Showy penstemon is one of the outstanding native perennials of Southern California where it commonly grows in sage scrub and chaparral plant communities. It is a tall species that produces numerous 3-5 ft. tall stems that become covered with rich purple-blue flowers in mid to late spring.

Showy penstemon is naturally suited to native landscape plantings in the Inland Empire in combination with the Coast live oak and the Desert willow. It grow best on well drained soils, in full sun and with low amounts of supplemental water during summer. It combines well with other scrub and desert perennials and around boulders, on banks and for seasonal accent value.
