I photographed these on the edge of a peat bog, and I have no idea what species it is. If you do, please let me know in the comments:
Olympus Stylus 1s, 42mm, ISO200, f5.6, 1/125s
These have a slightly pink hue, but they can pass as white, I think, and they do have Very Many Petals:
Olympus Stylus 1s, 42mm, ISO125, f5.6, 1/160s
Thanks for watching!
More white petals here.
