Plants Toxic to Animals


This guide aims to recreate the information found in the now defunct Plants Toxic to Animals database, originally created by Mitsuko Williams in the late 1990s. The plant species covered in this LibGuide are commonly found in the midwestern states, though common house plants are also included when applicable. The plants are listed both by their common name and by their scientific name. 

Note: There is a difference between "toxic" and "poisonous." Poisons are typically ingested, whereas venoms are injected, such as a snake's venom being injected with their teeth. 

This guide would not be possible without Mitsuko Williams' Plants Toxic to Animals database.
