A number of species of Mertensia are abundant throughout the blooming season in the Four Corners area.  At lower elevations, Mertensia appear in April; in the San Juans and nearby mountain ranges, Mertensia appear as short plants in open meadows and woods in the spring, tall plants along streams at higher elevations in the summer, and dwarf plants above timberline.  On any plant, flower color of the dainty, drooping bells often varies from purples and blues to very light pinks depending on how long the flowers have been open.

     The most prominent display of Mertensia is along mountain streams where Mertensia form large, dense colonies with thousands of sweetly scented flowers.

     The genus was named by Albrecht Roth in 1797 for F. K. Mertens a German botanist  of the late 1700s and early 1800s.  (More biographical information.)

These plants are over three feet tall and the photo covers just a small fraction of the thousands of square feet of Mertensia ciliata that perfume the air at tree-line on the Sharkstooth Trail  --  and on many other Four Corners mountain trails  --  in July and early August.
