Is giant trillium safe for cats and dogs?
Use caution. Giant Trillium is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. 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. Trillium chloropetalum is not individually listed by the ASPCA. Like other sessile Trilliums, roots and berries are the most potentially problematic parts; the toxic principle is not formally confirmed. Keep pets and children from ingesting any part. Contact ASPCA Animal Poison Control (888-426-4435) if ingestion is suspected.
