I noticed these a couple of days ago. We certainly get them every year, but not this early in the season. When the flowers bloom, they look like the blossoms from a Lilly of the Valley, but I don’t think that’s what these are. They blossom with 1 flower per stem and last about a week or so. I’m curious, so if you have a theory on them, I’d like to know what they are. So far I haven’t found them in any of the wild flower references.
