Columbian Monkshood-Aconitum columbianum

Growing up to six feet tall in moist area and producing dark purple flowers is Columbian monkshood (Aconitum columbianum). It's a member of the Buttercup Family (Ranunculaceae), although the lower leaves on the plant look almost maple-like.
 
The flowers supposedly resemble monk's hoods, hence the common name.

The petals of the plant are actually inside the protective covering formed by the sepals, along with the reproductive parts. A bee pollinates this highly specialized flower.

I saw buds, flowers, and seed pods all in the same area, showing the different stages all at one time.

Only one species of Aconitum grows in this area, making it fairly easy to identify. It also can form short vines, making it more distinctive.
