Prairie Lily
Zephyranthes drummondii
Prairie Lily (Zephyranthes drummondii), also called Rain Lily or Zephyr Lily, is a bulbous flowering plant toxic to cats. It belongs to the Amaryllidaceae family and contains lycorine and related phenanthridine alkaloids — the same compounds found in Amaryllis, Daffodil, and Blood Lily. The bulb carries the highest toxin concentration.
Important Notes
Toxic compounds: lycorine and phenanthridine alkaloids; bulb most concentrated
Mechanism: lycorine directly activates the emetic centre in the brainstem; higher doses cause vasodilation, hypotension, and CNS depression
Symptoms: vomiting, diarrhea, drooling, tremors; severe bulb ingestion may cause low blood pressure and convulsions
Bulbs are the most dangerous part — relevant during planting or when stored
Contact your vet if your cat ingests any part of the plant, especially the bulb
