Is Downy Painted Cup toxic to dogs?

Castilleja sessiliflora

Mildly toxic to dogs

Mildly. The ASPCA lists downy painted cup as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Castilleja sessiliflora is a secondary selenium accumulator: in high-selenium soils it concentrates selenium in leaf and root tissue to potentially toxic levels. ASPCA does not list the genus as definitively safe; ingestion may cause selenium-related symptoms (lethargy, hair loss, hoof/nail changes in livestock, gastrointestinal upset in dogs and cats). Keep pets from grazing this plant.
