A neat but poisonious plant
Caulophyllum thalictroides or Blue Cohosh is a great plant that I just caught in bloom. This plant is typically found in part to full shade and in moist, rich woodlands. It is a simple plant, but the leaves and shape make it quite stunning. Once the yellow flowers pictured are done, it will have beautiful blue berries, don't eat these berries as they are poisonous!!
Herbalists will use the root of the blue cohosh for various purposes, but I am opposed to the digging and disturbing of any native, wild plant! If it is garlic mustard or lesser celandine, feel free to pull at your heart's content!
I know it may not look like much, but in the backdrop of a woodland setting it is quite a neat plant to happen across. Look for this, and a very similar looking plant, early meadow rue if you take any jaunts this weekend!
