Penstemon filiformis is an uncommon species of Penstemon known by the common name threadleaf beardtongue.[1][2] It is endemic to the Klamath Mountains of northern California , where it grows in forest and woodland, often on serpentine soils. It is a perennial herb growing up to half a meter tall, its stem hairy and woody toward the base. The leaves are very narrow, linear and rolled to threadlike, reaching up to 7 centimeters long, those low on the plant sometimes borne in clusters. The inflorescence produces hairless, tubular or funnel-shaped blue to purple flowers just over a centimeter in length.[2]
