What to do
Contact a vet if the rhizome (underground stem) was dug up and eaten; leaf/flower contact is usually milder.
Toxic component and mechanism
The toxic component in Iris is irisin/irone, concentrated in the rhizome.
Part-specific risk: Rhizome is more concentrated in toxins than leaves or flowers.
What makes this plant different
Iris toxicity is concentrated in the rhizome (the underground stem), which most pets never encounter unless they're actively digging — a dog that simply brushes past iris foliage in a garden bed is at much lower risk than one who unearths the root.
