Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Iris tissues, especially rhizomes, can cause gastrointestinal poisoning and should not be ingested.
- Why it is dangerous
- Rhizomes and other iris tissues contain irritating compounds that can cause severe digestive upset when swallowed.
- How to recognize a risky encounter
- Confirm broad swordlike leaves and a three-part iris flower, but do not rely on color alone.
- What to do
- Do not taste or prepare wild iris material; wash hands after contact with cut rhizomes or sap.
Responsible observation
- Identify: Look for three broad falls with contrasting lines beneath upright petals.
- Observe: Appreciate color variation without picking blooms or dividing clumps.
- Protect: Stay off dense leaf fans and surrounding coastal vegetation.
