Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Lupine tissues contain alkaloids and should not be ingested by people or pets.
- Why it is dangerous
- Seeds and foliage can contain quinolizidine alkaloids that cause poisoning when enough material is swallowed.
- How to recognize a risky encounter
- Look for blue pea-shaped flowers above leaves divided into several narrow leaflets radiating from one point.
- What to do
- Do not taste any part, and keep children, pets, and grazing animals from consuming the plant.
Responsible observation
- Observe: View flower spikes without entering fragile sandy vegetation.
- Identify: Count the narrow leaflets radiating from each leaf center.
- Protect: Leave all plants rooted because specialist larvae depend on them.
