Is lobelia erinus 'cascade blue' safe for cats and dogs?
Toxic — the ASPCA lists lobelia erinus 'cascade blue' as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Lobelia species contain piperidine alkaloids (notably lobeline) and are considered toxic; while L. erinus is not individually itemised on the ASPCA list, lobelias are widely documented as toxic to pets and people if eaten, causing vomiting, diarrhoea, salivation and, in larger amounts, tremors. Treat as toxic and verify with a vet if ingested.
