Why the guidance differs

Pet Poison Helpline describes digestive effects in dogs and cats for spring-blooming Crocus; VPIS lists Crocus species as pet-safe. Preserve this disagreement as a caution guide. NC State identifies C. vernus in the photo evidence; the general Crocus care guidance is narrowed to this spring-blooming species. Colchicum autumnale is excluded.

A disagreement between references does not cancel a toxicity warning. We keep those warnings visible while the assessment remains unresolved.
