Blueberries? In the dead of winter? What plant is this?
Answer
Blue cohosh.
These blue berries belong to the plant blue cohosh (Caulophyllum thalictroides). If no berries are present, other telltale signs of this plant in winter are the somewhat hourglass-shaped flower stalks and a shiny, tan stem that bulges at the nodes (where the stem branches).
