Safety & handling

- Toxicity notes
- Iris plants are toxic to cats, dogs, and horses, with the highest concentration of harmful compounds found in the underground bulbs and rhizomes.
- Edibility
- Some culinary use
- Handling notes
- All parts of the iris plant are toxic, but the roots and rhizomes carry the highest concentration of irritating compounds. When handling irises, the primary risk comes from the plant's sap, which contains compounds like irisin, iridin, and pentacyclic terpenoids.
