Subject: Thanks for info on poison plants
Date: Thu, 18 Feb 1993 21:04:50 GMT
I would like to thank everyone who posted responses to my query
about references for toxic plants. I have gotten the information
I needed. Several people asked me to share the information I received,
so I am going to give a quick synopsis here.
1) contact local county extension agency
2) contact local poison control center
3) AMA Handbook of Poisonous and Injurous Plants
4) Sunset book "Making Your Home Child-Safe"
5) Kay Klier recommended a book she believes the title to be
"Daffodils are Poisonous" (I'm going to look for this)
She also recommended another book but believes it to be out
of print. This information was posted to rec.gardening.
6) A coworker sent a list from rec.cats when she saw my posting
It's long but I will e-mail it to anyone who sends me an email
request for it.
