I have attempted to include as many hazardous plants as possible. If you are not sure if a plant is poisonous, we recommend you contact your Poison Control Center. I will add more as I come across them. This list is for reference only! If you have a plant you feel should be listed please e-mail it to riffe@oocities.com, please place "toxic plants" in the subject header. Thank you.
