Is Pontederia cordata 'Alba' toxic to dogs?

Mildly. The ASPCA lists pontederia cordata 'alba' 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. Pontederia cordata and its cultivars are not individually listed by the ASPCA. While the species is documented as historically human-edible when cooked, that is not a substitute for ASPCA pet-safety grounding; treat with caution and verify with a vet before assuming it is safe for cats or dogs.

Pontederia cordata and its cultivars are not individually listed by the ASPCA. While the species is documented as historically human-edible when cooked, that is not a substitute for ASPCA pet-safety grounding; treat with caution and verify with a vet before assuming it is safe for cats or dogs. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to pontederia cordata 'alba'.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
