List of Poisonous Plants

This is a list of plants I've gleaned from a variety of sources on the internet. It is by no means definitive and not necessarily accurate. This list is by scientific name, so you'll need to do a "CTRL + F" search of the page if all you have is a common name.

These plants cause discomfort, injury, and/or death in humans, pets, livestock, and/or wildlife. Symptoms range from mild to severe to deadly. Plants can be a edible, poisonous and a medicinal all at the same time.
