Glory Lily

Glory lily is prized as a garden and container plant for its dramatic, flame-like reflexed petals, but the whole plant — and especially the tuber — contains a powerful toxin called colchicine. Despite the "lily" in its name it isn't a true lily, and even a small amount can lead from bloody vomiting and diarrhea to shock and multi-organ damage, so keep it out of your home.

Named a lily, but the poison is colchicine

What glory lily causes isn't the same poisoning as a true lily but colchicine poisoning, which strikes rapidly dividing tissues — bone marrow, the gut lining, the liver, and kidneys — all at once. It shares essentially the same danger as autumn crocus, which contains the same colchicine, so keep both plants well away from cats.

How cats get exposed

The flowers, leaves, and stems are all hazardous, but the toxin is most concentrated in the tuber. Repotting, when the tuber is exposed above the soil, is especially risky, and a cat can be exposed by digging in the soil or chewing a fallen petal.

How symptoms progress

Signs usually begin 6–24 hours after ingestion with drooling, bloody vomiting, and bloody diarrhea. Colchicine poisoning is marked by a delayed pattern: the early digestive signs may seem to settle, then 24–48 hours later bone-marrow suppression and liver and kidney damage emerge. A mild-looking start is no reassurance.

What to do right now

If there's any sign of chewing or swallowing, get to a 24-hour emergency vet immediately even if symptoms are faint. Don't induce vomiting at home, and tell the vet if the tuber may have been involved. Colchicine has no specific antidote, so early care and intensive support decide the outcome.

Safer plants instead

If you want a showy potted bloom, confirmed-safe gerbera daisies or roses are good choices.
