POISONOUS to livestock.

Symptoms include nausea, vomiting, abdominal pain, diarrhea, elevated temperature following ingestion; skin irritation upon contact with seeds, rootstock, or cell sap. Toxic Principle: Irisin, iridin, or irisine.
The rhizome of the Blue Flag is poisonous, but was used by colonists, with guidance from Indian people, for various healing purposes. (Poisonous Plants of N.C.)
Through the years, iris flowers have symbolized power, with the three parts representing wisdom, faith and courage. (Kershaw)
Irises have been used medicinally in the past, but their rootstocks are dangerously poisonous. Some tribes used the two outermost fibres of the leaves to spin strong, very fine, highly esteemed twine. Powdered iris root, called orris, smells like violets and has been added to perfume and potpourri. (Kershaw)
Irises, not lilies, are the flowers that are stylized as the fleur-de-lys emblem, first of the French monarchy, and today of the province of Quebec.
(Harris, Marjorie, 2003. Botanica North America)
Muskrats do eat the root stock. (USDA)
