This is a very poisonous plant. But I was unaware of this until a neighbour asked us to confirm if this existed on her property. It did in some large well established clumps at the water's edge. But I also found a number of individual plants on our own land nearby. Look elsewhere for identification details. Water parsnip is very similar in many ways and existed close by. But it is not poisonous and is easy to distinguish once you've researched things properly. I've looked carefully around the shore of North Otter Lake and so far only come across a couple of isolated specimens - no other big clumps.
