FAQ
Is zebra haworthia the same as the "zebra plant"?
No — several different plants share the nickname, and every ASPCA entry that uses it is non-toxic. Zebra haworthia is a Haworthia, the striped rosette succulent on this page: the ASPCA lists Haworthia species ("Many cultivars") as non-toxic to dogs and cats, and Pet Poison Helpline names Haworthia among succulents that are non-toxic to pets — S0 Safe. The plant sold as zebra plant is usually Aphelandra squarrosa, a leafy houseplant with white-veined leaves, which has its own record: S0 Safe on our zebra plant page, where the ASPCA lists it as non-toxic to cats, dogs, and horses. A calathea can also be sold as zebra plant (our calathea page, also S0 Safe), and the ASPCA's Pheasant Plant entry (Cryptanthus zonatus), which lists Zebra Plant as another name, reads "Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses"; we have not graded that plant ourselves.
