Spent a fair bit of time today wandering around a medium-elevation bog. Plants were about the same stage as those at sea level, though a couple of pond lilies still had underwater buds (!) This was particularly interesting, because I could see almost all of the stages of flowering at once. I had never studied their blooming cycle that closely. I was fascinated at how the pods dissolve in the still, tea-colored water of the bog ponds; I could see scatterings of seeds underneath several plants.
I always feel a little guilty picking a pond lily flower or seedpod. They're so big, and so gracefully-formed: like urns or chalices. But there were so many this summer that I'm not feeling too terrible about it. Several of my plant books say the seeds are edible and tasty. I'd say edible, perhaps borderline tasty. They're big, anyway: as big as grains of Calrose rice.
