Penstemon Haydenii

Blowout penstemon (Penstemon haydenii) is a species of beardtongue in the Plantaginaceae family. The warm-season perennial plant is native to nine counties in the Nebraska Sand Hills and a single location in Carbon County, Wyoming. The plant has a milky-blue color with a waxy cuticle, pale purple leaves, and alternating leaf pattern with one central stock. The flowers, while in the inflorescence stage, originate from the bases of the leaves of the plant. Blowout penstemon flowers from May until early June and drops the seeds late August into September.

Blowout penstemon grows on bare sand dunes. It is resistant to the abrasive forces of the blowing sands with its incorporation of a protective thick waxy cuticle. Other plants are often cut off by the scouring sands as they sprout.

Another adaptive feature for the blowout penstemon plant is the lifespan of the seeds. The seeds dropped in late August into September can remain buried dormant in the sandy soils for decades and still remain viable. Prolonged wet conditions and abrasion are required for breaking dormancy and seed germination. The plant is primarily an out-crosser (transfers genes from one plant of the same species to another plant of the same or closely related species); although studies show that it is potentially self-fertile.
