Plant Description and Details
The royal blue trumpets of the Wasatch Penstemon can be found on the foothills and mountains of the Wasatch Mountain range of Utah and its range extends to SE Idaho. A low-growing basal whorl of leaves supports severalflower stalks, each holding multiple flowers in rounded bunches. The name "cyananthus" means "blue-anthered penstemon," but the flower anthers can also be green. It is almost identical to the similarly-named Penstemon cyanEUS, but it has a wider range.
