I am looking for a list of poisonous plants for South Dakota. I am presenting to area day care providers about outside play and wanted a great resource to give them on this topic. Thanks so much.
Sorry for the delay in responding to your question. I was checking with a colleague to see if he knew of such a list. The best suggestion was this:
"Poisonous plants of the central United States" by H. A. Stephens
He also cautioned that one must also be careful of houseplants and landscape ornamentals that could be poisonous as well. I seem to recall a book that I had called "Baby Safe Houseplants" but I was not able to locate it in my collection at the moment.
Certainly there are many lists online if you do a search.
I hope that helps.
