Mayapple flower in blossom.
Plants that bear only one leaf will not produce a flower. Those that bear 2 leaves will produce a single white flower in the fork of the leaves.
This flower will, in turn, produce an "apple" (really a berry) that will ripen later in the summer. I've never tasted one (yet), but they are not poisonous (the rest of the plant is, though!).
A special treat that Dave and I came across today during a hike: wild onions! They were growing quite plentifully in the woods across the road. I think these will go nicely in a salad of "baby" greens picked from our garden!
