Mertensia ciliata are oval to lance-shaped and pointed. The inflorescence is an open array of many clustered blue bell-shaped flowers each between 1 and 2 centimeters long. The hanging, fragrant flower is tubular, expanding into a wider, lobed mouth. The flowers and leaves are edible. As the individual flowers progress in age they change in color from blue to pink-red. The flowers bear poricidal anthers and are fertilized via buzz-pollination by several "Bombus" species. Primary Nectar robbing by "Bombus" species, including "Bombus occidentalis" is common in some populations. Mertensia ciliata Mertensia ciliata is a species of flowering plant in the borage family
Borage amounts (2-10 ppm of dried herb) of the liver-toxic Pyrrolizidine alkaloids (PA) intermedine, lycopsamine, amabiline and supinine and the non-toxic saturated PA thesinine. PAs are also present in borage seed oil, but may be removed by processing. The German Federal Institute for Risk Assessment has advised that honey from borage contains PAs, transferred to the honey through pollen collected at borage plants, and advise that commercial honey production could select for raw honey with limited PA content to prevent contamination. Traditionally, "Borago officinalis" has been used in hyperactive gastrointestinal, respiratory and cardiovascular disorders, such as gastrointestinal (colic, cramps, diarrhea), airways
