Wisteria Vine Toxic?

UCDavis lists wisteria as: "Minor Toxicity: Ingestion of these plants may cause minor illnesses such as vomiting or diarrhea. If ingested, call the Poison Control Center or your doctor."

They are talking about humans but also say, "If a plant is known to be hazardous to humans, it will probably be toxic for animals as well."

The ASPCA  also has bad things to say about wisteria with regards to cats, dogs and horses.

The Canadian Poisonous Plants Information System  talks a little about human poisoning from Japanese wisteria but, whereas it is a great source of information for farmers on livestock poisoning - it says nothing about livestock having problems. Nor, does it say anything about the many other species of wisteria.

edited to add: Poisonous Plants of North Carolina, North Carolina State University doesn't list wisteria.

We keep ours in check, but the chooks and turks ignore them.  If they're not planted on the run fencing they shouldn't be a problem.  Ingestion would result in GI irritation and diarrhea so the main threat would be dehydration.

We have several, but all are severely controlled:


The chooks and turks also ignore the local, poisonous, volunteers (the cicadas get munched, but the berries are ignored):


Since you have so much of the stuff I thought I'd add this link on the many uses it can be put to:

Glad I read this. I have a huge Wisteria vine that grows up onto a tree play house my husband built. It's really beautiful. Anyway, my chickens have started eating the flowers! They jump up to get them, they look funny. anyway I guess I will have to trim them up. Not looking forward to it though, they are so gorgeous.
