"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

BRIEF: Could you give me some information on Hollyhock?

I visited your web site to find out if the plant, Hollyhock, might be toxic. My dogs sometimes get into the garden, and go for that plant. I haven't had it in my garden before. They seem to have intestinal problems after eating it. I did not find it listed on your Poisonous Plants Web Pages. Might you be able to give any information about Hollyhock?


I can't tell you much more than you already know - it can cause skin irritation and dermatitis in some people and GI irritation in animals if eaten. It is in the same family as cotton and velvet leaf, so I imagine if your dogs ate lots and lots of seeds that they could also be poisoned by cyclopropanoids, but with luck their recent experience will help them learn to back off a bit.
