Is edging lobelia safe for cats and dogs?
No — edging lobelia is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The ASPCA lists Lobelia (including Lobelia cardinalis) as toxic to dogs, cats, and horses. The toxic principle is lobeline, a piperidine alkaloid. Clinical signs of ingestion include vomiting, diarrhoea, excessive salivation, abdominal pain, depression, and cardiac rhythm disturbances. Lobelia erinus belongs to the same genus and should be treated as toxic; keep away from pets.
