What our table adds

Severely toxic — every part, especially the seeds, can cause liver failure and is often fatal even with treatment. If a pet has eaten any of it, this is a vet emergency, not a wait-and-see.

How this page is made

Every line about this plant comes from the curated table behind our plant checker, as it stands. A verdict appears only beside the ASPCA listing that states it; where the table has no such source, the page says “Not assessed” instead of guessing.
