I had originally identified this flower as a winter aconite, Eranthis hyemalis, but now I’m pretty sure that’s wrong – the leaves aren’t like that, and no image I can find shows this green translucent ‘berry’ springing from the middle. So if you know what this is, feel free to enlighten me. All I can say right now is that these are tiny flowers perhaps a centimeter across, that appear very early in the spring – last year they got nailed by one of the freezing rain storms and emerged none the worse for wear. They have a nice, delicate color that you’d have to be practically crawling on the ground to appreciate, unless you happen to know a friendly nature photographer that can provide close up images…
