whitest evening-primrose, Oenothera albicaulis

Traveling routine; up, shower, dress, look for flowers while others get ready for the day. By the time we're on the road, there are fresh images in the camera and the mind. Whitest evening-primrose was the ideal subject. What better time to find it than morning. By mid day it will fade. And it's hard to shoot when it opens at night. Not hard to find, being 'whitest', but hard to shoot. Whitest grows in AZ, CO, IL, KS, MT, ND, NE, NM, NV, NY, OK, SD, TX, UT, and WY. Logan CO CO, 6/25/13. Willow-herb family, Onagraceae.
