FAQ
Is speedy henry the same plant as inch plant?
Yes, on the ASPCA record. Three ASPCA entries, including Inch Plant and Variegated Inch Plant, give the same scientific name, Tradescantia fluminensis, list "Speedy Henry" as another name, and carry the same verdict — "Toxic to Dogs, Toxic to Cats, Toxic to Horses" — and the same single sign, "Dermatitis." This page covers that one species, not every plant in the genus Tradescantia, so check the scientific name on the tag. If it matches, keep the plant out of reach and watch for a skin reaction.
