Garden Plants Toxic to Dogs and Cats: Every Listed Plant, by Type

Gardeners with a dog that digs or a cat that chews ask this before they plant, and the honest answer has two halves: what the authorities list, and what nobody has finished checking. This page is the first half, for every plant in our library. A plant is here when a named authority, such as an extension service, a horticultural society or a pet poison service, lists it as toxic to dogs or to cats. One listing is enough, and where another source we check disagrees, the warning still stands and the plant's line says so.

The ones most gardens already grow

Start here: these are the kinds most likely to be in your ground or on your patio already. Each row prints the plant's own listing, and how many of the library's varieties it stands for.

Every listed plant, by type

The complete list, one growth habit at a time. A chip names a plant, or a group of varieties, and opens a plant page where the listing is named and linked. When only some of a group's varieties carry the listing, the chip names the group and says how many.

How to read a listing

Every line on this page is one plant's own listing, in the same words its plant page uses. A toxic line names the institution whose own page lists the plant as toxic to that animal, and links that page. When dogs and cats read differently, each gets its own line. A line that says another source we check lists it differently marks a disagreement: one source warns, another does not, and the warning is what you see.

Not being on this list is not the same as being listed as non-toxic. 723 plants in our library are not yet checked for either animal, and a plant with no toxic listing found is only that: none of the sources we check lists it. Our plant library's pet filter keeps the plants listed as non-toxic and the ones with no toxic listing found, and leaves out the rest.
