About

Lilium longiflorum, often called the Easter lily, is a species of plant endemic to both Taiwan and Ryukyu Islands (Japan). Lilium formosanum, a closely related species from Taiwan, has been treated as a variety of Easter lily in the past. It is a stem rooting lily, growing up to 1 m high. It bears a number of trumpet-shaped, white, fragrant, and outward-facing flowers. This species, along with most other true lilies, are highly toxic to cats.

How this plant poisons

L. longiflorum is toxic to cats. The true mechanism of toxicity is undetermined, but it involves damage to the renal tubular epithelium (composing the substance of the kidney and secreting, collecting, and conducting urine), which can cause acute kidney injury. Veterinary help should be sought, as a matter of urgency, for any cat that is suspected of eating any part of the lily – including licking pollen that may have brushed onto its coat.
