Fun, weird, helpful, or little known fact
A tall (up to 4’), leafy senecio with unbranched stems that have numerous, triangle-shaped, toothed leaves, topped by yellow flower clusters of 10 to 30 heads.  It grows near bluebells, monkshood, and other tall, water-loving, subalpine species. Look for the triangle!
