Upon major, major searching, I finally found two references to Hardy Geraniums on poisonous plant lists. They did not mention just how toxic, toxic parts or symptoms. I wonder how dangerous they really are when hardy geraniums are rather common garden flowers yet it was difficult to find any lists mentioning them.

Any list of poisonous perennials that I've seen (been gardening and working in the industry for years) does not include any Geranium sp.

Here is a link that might be useful: University of Vermont list of

Geranium x 'Johnson's Blue' "...poisonous"

I'll be danged if I can find the 2 poisonous plants lists again that I saw with Hardy Geraniums on them. Saw many lists without them listed though. That's why I wasn't overly concerned. It just took me by surprise when my friend mentioned them as being toxic. That's why I was asking if anyone heard of this before. Thanks so much, cpg!

Do you grow azaleas? rhododendrons? ivy? daffodils? daphne? they are all toxic..... dogs aren't usually poisoned by garden plants but by anti freeze, onions, chocolate and tylenol. I would not worry about hardy geraniums.
