Ohio Buckeye vs. Buckeye: which is safe for cats and dogs?

Ohio Buckeye and Buckeye are frequently compared because they share the same common-name alias, leading to confusion for pet owners trying to identify potential hazards in their landscape. It is important to understand that both plants are considered potentially toxic to cats and dogs. Whether you are dealing with the specific Aesculus glabra or other varieties within the genus, all parts of these trees, especially the seeds and leaves, contain harmful glycosides and saponins. Ingestion can lead to serious gastrointestinal distress and neurological symptoms in both species. Because the risk is significant for all pets, you should keep these plants well away from your animals.
