Showy Penstemon (Penstemon speciosus) is one of the most strikingly beautiful native penstemons of the western United States. Commonly found in dry meadows, sagebrush flats, and open pine forests from California to the Rocky Mountains, this perennial wildflower is known for its vivid, sky-blue to violet-blue tubular flowers with a pale interior and pronounced nectar guides. These floral spikes emerge in late spring to early summer, rising above low, lance-shaped foliage in mounded clumps.

 

Showy Penstemon is a valuable nectar source for native bees, especially bumblebees, as well as hummingbirds and butterflies. Its bold flowers bloom during a critical time when pollinator activity is increasing in the late spring, helping bridge the seasonal gap between early- and mid-summer wildflowers. This species is often included in dryland and montane restoration mixes due to its attractiveness, low water needs, and strong wildlife value.

 

Showy Penstemon thrives in full sun and well-drained soils, including sandy, gravelly, or volcanic substrates. It is drought-tolerant once established and performs well in both garden and wildland settings. Seeds require cold stratification for optimal germination and are best sown in the fall or stratified before spring sowing.
