Resistance & tolerances

Drought: Water while establishing; avoid keeping roots constantly wet.
Wet soil: Poorly drained soil can rot rhizomes.
Deer & rabbits: Resistant, not browse-proof.

Resistance is not a guarantee; deer and rabbits may browse any plant.

Keep in mind: Harmful if eaten; sap can irritate skin. Wear gloves when dividing.

Growing & care

Pests: Check for iris borer.
Fall cleanup: After a hard frost, remove old leaves, stems and nearby debris to reduce overwintering iris-borer eggs.
