This pretty flower grows in the rockiest places here. It's pinkish until it opens. I love the symmetry of the flower with its four heart shaped petals. The medical supplement evening primrose oil is made from the seeds, not sure of this particular evening primrose or not. Supposedly when the plant dies it curls up to form a bird cage structure, but I haven't seen that either.
We're taking an overnight trip to Leadville, Colorado. I'll post all about it when I return Friday night or Saturday.
