Penstemon linarioides subsp. linarioides is found on dry hillsides and roadsides at middle elevation. The leaves are linear and the corollas are lilac. The leaves are crowded toward the base, becoming less so higher on the stems. The flowers are "secund," meaning they form mostly on only one side of the stem.
