It's our earliest wildflower, the one with the unlovely common names, Slink Pod and Fetid Adder's Tongue, Scoliopus bigelovii. I recently found one blooming in our forest. You can see its leaves are just peeking up at the base of the stem.
Craig Tooley took this close-up photo, which is in our book, Mendonoma Sightings Throughout the Year. Yes, it's a MUCH better photo than mine! The leaves of this member of the Lily family are distinctively mottled. If you find the leaves, which can grow to 12 inches long, you know where to look for the earlier-blooming flower next winter.
