Editor's Note

Rhizomes (thickened roots) and rootstocks, fresh or dry, of all Iris species and cultivars are poisonous if ingested. Symptoms include nausea, vomiting, abdominal pain, diarrhea and elevated temperature following ingestion. Some resources claim the toxic principal (irisin, iridin, irisine) only cause low toxicity if eaten.

Skin irritation can develop upon contact with seeds, rhizomes, rootstock, or cell sap.

We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents, and pet owners to look further for more information.
