Parkgate Tarn is literally awash with these beauties. Don't try going too early though, they seem to work about 9 to 5!! The rest of the time they're shut.
Well captured -- I love photographing lilies as each looks so different when you study them though they look alike from a distance. There's a marsh on Beaver Island that often is covered with them. I plan to check them out this week.
We've had them in our (former) pond. We picked some and put them in a vase. They still followed their own biological rhythm of opening up in the morning and closing in the evening. Wonderful!
