Caulophyllum giganteum

early blue cohosh

Giant blue cohosh blooms in early spring, a few weeks before its close relative blue cohosh, and grows up to 3' tall. In the early season, leaves uncurl like fiddlehead fronds. This striking plant flowers and fruits as uniquely as it emerges, and makes for a great addition to woodland gardens.
