Quick answer
ASPCA classifies Hosta as toxic to cats and dogs, while NC State Extension and Kew establish the accepted identity as Hosta plantaginea.
Plant identity and scope
This record is limited to Hosta plantaginea. ASPCA prints Hosta plataginea; NC State Extension and Kew independently use the accepted spelling Hosta plantaginea for this species.
Identity reconciliation: Hosta plataginea → Hosta plantaginea (NC State Extension and Royal Botanic Gardens, Kew).
Governed aliases: Plantain Lily, Funkia.
What the evidence supports
The toxic result is limited to the source subject reconciled to Hosta plantaginea. PawPlants does not silently broaden that species record to every Hosta species or cultivar.
Safety classifications come from PawPlants' governed evidence record, not from a retailer or product label.
If exposure may have occurred
Prevent further access, retain the plant label or cultivar information, and contact a veterinarian or animal poison-control service for case-specific advice. Do not induce vomiting unless a veterinary professional directs it.
