I found this plant blooming at Denali NP along the Savage River Trail. The petals are supposed to open at the top of the flower, but I never saw that. Perhaps they have to have direct sunlight to cause them to open. The smoke from the fires above Fairbanks drifted in the Denali valley and kept the sun from shining, so the flowers may have stayed closed.
These flowers were blooming along the trail to the Harding Ice Field at Kenai Fjords National Park. They are related to the Bishop's Cap or Miterwort (Mitella) of our area.
The color of this flower was one that I have never seen in a flower before, it was a greenish-blue. The plant was about 3 inches tall growing among the rocks on Flat Top Mountain.
