a close-up photo of a prairie goldenrod flower

Solidago ptarmicoides

Prairie Goldenrod (Solidago ptarmicoides) is considered imperiled in Colorado (S2) but is secure globally.  It is our only goldenrod which isn’t yellow, and quite frankly, doesn’t look much like our usual goldenrods.  The photo was taken by Rick Brune.

a photo of an Arctic Yellow Violet in a rock crevice

Viola biflora

Arctic Yellow Violet (Viola biflora) is a native wildfower of the montane and subalpine on the Front Range.  It is considered vulnerable in Colorado, the only state in the U.S. where it is found.  But globally it is considered secure because it also occurs in Canada in British Columbia and the Yukon Territory, and in Alaska. Marlene Borneman took this photo.

a photo of Rocky Mountain sky pilot in alpine tundra

Polemonium viscosum

Sky Pilot (Polemonium viscosum) is a Colorado endemic plant, and in spite of that is is only listed in Colorado as imperiled (S2), and globally as aparently secure (G4).  The reason for such low ratings is because it is found in 10 counties with extensive populations that are well protected.  This photo is by Jim Pisarowicz.
