Jasmine

The five "jasmines" — only two are cat-safe.

Usually yes — true jasmine is safe for cats. The ASPCA lists Jasminum species (the entire true-jasmine genus, family Oleaceae) as non-toxic to dogs, non-toxic to cats, and non-toxic to horses. Toxic principles: non-toxic.

The catch: "jasmine" is a common name shared by five different plants in four different botanical families, and three of those five are toxic to cats. Identifying which "jasmine" you have is the whole game.

The five-jasmine disambiguation matrix

This is the heart of the page. If you remember nothing else, remember this list:

| Common name | Botanical name | Family | ASPCA verdict | |---|---|---|---| | True jasmine | Jasminum species | Oleaceae | Safe (this entry) | | Star jasmine | Trachelospermum jasminoides | Apocynaceae | Safe (separate entry) | | Cape jasmine (= gardenia) | Gardenia jasminoides | Rubiaceae | Toxic (gardenia) | | Night-blooming jasmine | Cestrum nocturnum | Solanaceae | Toxic (Cestrum entry) | | Carolina jessamine | Gelsemium sempervirens | Gelsemiaceae | Toxic (vet literature) |

Two safe, three toxic. The safety question is entirely a question of which plant you have. Check the plant tag. If the botanical name on the tag is Jasminum officinale, Jasminum polyanthum, Jasminum sambac, or any other Jasminum, it is true jasmine and ASPCA-safe. If it is anything else, look it up specifically.

Why the ASPCA verdict only covers true Jasminum

The ASPCA entry is specifically for Jasminum species — the Oleaceae genus that is the botanical "jasmine." Other plants got the common name because they smell like jasmine, but they are unrelated genera. Common names are unreliable; the botanical name is the only field that matters for toxicity.

The verdict, verbatim: Toxicity: Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses · Family: Oleaceae · Scientific Name: Jasminum species · Toxic Principles: Non-toxic.

The three toxic "jasmines" — what to actually worry about

Carolina jessamine (Gelsemium sempervirens) is the most dangerous of the three. The yellow trumpet flowers are sometimes mistaken for true jasmine in a quick glance even though the colour and growth habit are different. Contains gelsemine and related indole alkaloids that produce respiratory depression, muscle weakness, ataxia, and seizures. ASPCA does not maintain a direct entry but veterinary literature is unambiguous — treat as highly toxic.

Night-blooming jasmine (Cestrum nocturnum) is in the nightshade family (Solanaceae), the same family as deadly nightshade, jimsonweed, and tomatoes. Contains saponins and tropane alkaloids. Produces vomiting, salivation, weakness, and neurological signs in heavy ingestion. ASPCA's Cestrum entry confirms toxicity.

Cape jasmine is just gardenia under a different common name. Gardenia jasminoides contains genioposide and gardenoside — ASPCA lists it as toxic with vomiting, diarrhea, and hives as expected clinical signs. See the gardenia page for the full profile.

True jasmine in a cat household

If you have confirmed your plant is true Jasminum, treat it as a safe houseplant. Cats may bat at the small star-shaped white flowers; the strong fragrance often deters chewing. Pair with:

• Lavender — another fragrant ASPCA-safe option (with the live-plant-vs-essential-oil caveat that applies to all aromatic herbs).
• Hibiscus — non-toxic flowering shrub for similar conservatory placement.
• Rose — non-toxic, classic fragrant companion.
• Honeysuckle — non-toxic climber for the same sunny corner.

Avoid placing true jasmine next to gardenia, oleander, or any Cestrum species without barriers — those are the toxic plants most likely to be confused with jasmine at a glance by a guest or child filling a vase.
