Taper-leaf penstemon attracts many pollinators; especially bees and butterflies. This is a tufted perennial with upright stems.




Penstemon is a large genus with over 275 species scattered from Mexico to Canada. The common name for the genus is beardtongue which comes from the 1 non-fertile stamen present in Penstemon flowers. This is called the staminode and is usually hairy or looks "bearded." The other four stamens are fertile.














Penstemon in Greek pente means "five" and stemon means "stamen." This probably refers to the fifth stamen which is the staminode (sterile stamen) or to the fact that there are five stamens total.
Attenuates means "narrowed to a point," which most likely refers to the leaves.
