What are some common wild poisonous plants found in the State of WA?

Question

I'm trying to gather some information on a few of the more common ones to educate a group of Cub Scouts. Thank you in advance. (I think I can do my own research if you can provide some names?)

Answer 1

Here is a great web site from the WA Department of Health:

Answer 2

I lived in WA for 25 years... I believe the following are poisonous.

foxglove, rhododendron, poppies, buttercups, bracken fern, daffodil, hemlock, ivy. I believe foxglove and hemlock are the most notorious and would cause the most severe reactions.

Have fun, and good luck! My brother was an eagle scout :)
