This shockingly bright flower really stands out on the alpine tundra it favors.  Penstemon hallii grows to about eight inches tall in a tight mass of basal leaves and stems crowded with flowers. Flower color ranges from blue/violets though shades of purple/pink. The plant is found only through the mountains of Colorado.

Elihu Hall collected plants in the summer of 1862 in Colorado with his friend J. P. Harbour and famed botanist, Charles Parry, "King of Colorado Botany". (More biographical information.)
