Grahams beardtongue (Penstemon grahamii) is a herbaceous perennial. When in flower plants are easily sited. The colors of the flowers are brilliant lavender to pink and the tubular flower is long compared to other penstemon species. The flowers (3-20) are usually tightly arranged around the raceme pointing upward. There are 1 to 3 stems extending from the taproot, the stems are 7-18 cm long. Recently this Uintah Basin plant has become an interest and focus of research. The extent of the population is being reviewed and will be determined with the efforts of surveys conducted in the field.
