Penstemon cobaea

 

Prairie beardtongue

When In bloom large tubular flowers line at least half of cobaea beardtongue's 1-2 ft. stems. The flowers are white with dark purple lines inside the floral tube. One to three stout stems rise from the woody rhizome and bear thick paired leaves which become smaller up the stem. The lower leaves have often withered by the time of flowering.
