Mertensia franciscana is common along streams, in moist meadows, and in open woods.  It grows in small patches as pictured here, in three or four foot diameter bush-like clusters with hundreds of flowers in bloom at the same time, or, as pictured below, as individual plants.

"Franciscana" is for the San Francisco Peaks of Arizona which in turn honor St. Francis of Assisi.  Amos Heller named this plant in 1899 from a specimen collected by L. F. Ward in Utah in 1875.  (Click for biographical information about St. Francis.)

Leaves have small, glistening, pustulate-based hairs.  It is usually very difficult to see these hairs in the field, even with a 10x hand lens.  The hairs are appressed, quite fine, and quite short.  The pustulate base of the hairs shows as dark green circles.  Most often one needs a microscope to see these features.
