Why interaction risk is high
Iris tissues, especially rhizomes, can cause poisoning; do not ingest wild material or let pets chew it.
Why it is dangerous
Iris rhizomes and leaves contain irritating compounds that can cause gastrointestinal poisoning when swallowed.
How to recognize a risky encounter
Confirm broad fan-shaped leaves and crested flowers while leaving the underground rhizome undisturbed.
What to do
Do not taste or dig the plant; keep pets away and seek poison guidance after ingestion.
Responsible observation
  • Flowers: Look for a raised crest along each spreading petal.
  • Colony: Avoid stepping on shallow rhizomes and leaf fans.
