“Jasmine” is one of the most inconsistently applied plant names in gardening, and toxicity is exactly where that inconsistency becomes dangerous rather than just confusing. At least six commonly sold plants carry “jasmine” in their name, and they span from officially non-toxic to seriously poisonous — with no way to tell which one you have just from the word “jasmine” on a nursery tag. This guide compares them directly, because a search for “is jasmine toxic to cats” genuinely doesn’t have one correct answer.
Jasmine Toxicity at a Glance
| Plant | Botanical Name | ASPCA Status | Notes |
|---|---|---|---|
| True Jasmine | Jasminum species | Non-toxic (dogs, cats, horses) | Includes Arabian jasmine, common jasmine, pink jasmine |
| Star / Confederate Jasmine | Trachelospermum jasminoides | Non-toxic (dogs, cats) | Not a true jasmine; different genus (Apocynaceae) |
| Madagascar Jasmine | Stephanotis floribunda | Officially non-toxic; conflicting secondary reports of mild toxicity | 92%+ of reported incidents involved leaves/stems, not flowers |
| Cape Jasmine | Gardenia jasminoides | Toxic (dogs, cats) | Toxic principles genipposide and gardenoside; causes vomiting, diarrhea, and hives |
| Paraguayan Jasmine | Brunfelsia species | Toxic (dogs, cats, horses) | Toxic principle brunfelsamidine; causes tremors, multi-day seizures, vomiting, hypersalivation, incoordination |
| “Confederate Jasmine” (name overlap risk) | Gelsemium sempervirens | Highly toxic — contains neurotoxins | Sometimes called by the same common name as star jasmine; botanically unrelated and dangerous |
Is True Jasmine (Jasminum) Toxic?
No. True jasmine — the genus Jasminum, which includes Arabian jasmine, common jasmine, and pink jasmine — is listed as non-toxic to dogs, cats, and horses by the ASPCA. The plant belongs to the olive family (Oleaceae) and contains no identified toxic principles. As with any non-toxic plant, eating a large quantity can still cause mild digestive upset in some pets, but there’s no toxic compound at play.
Is Star Jasmine Toxic?
No. Trachelospermum jasminoides — also called Confederate jasmine, its older common name — is listed as non-toxic to both dogs and cats by the ASPCA. It isn’t a true jasmine at all; it belongs to the dogbane family (Apocynaceae) and only shares the common name because of its similarly fragrant, star-shaped flowers. See the full star jasmine care guide for more on this species.
Is Madagascar Jasmine (Stephanotis) Toxic?
This is the one genuinely ambiguous case on this list, and it’s worth stating both sides rather than picking one. The ASPCA’s official plant database lists Stephanotis floribunda as non-toxic to dogs, cats, and horses. However, a secondary source citing ASPCA Animal Poison Control Center data describes it as mildly toxic, noting that over 92% of reported incidents involved ingestion of leaves or stems specifically — not flowers — with symptoms appearing within 15 to 90 minutes of ingestion. Given this conflict between the official listing and poison-control incident data, treat the plant cautiously: keep it out of reach of pets regardless of which classification you trust, and contact a vet or poison control promptly if a cat or dog chews on the leaves or stems specifically.
Is Cape Jasmine Toxic?
Yes. Gardenia jasminoides, commonly called Cape jasmine despite not being related to true jasmine, is listed as toxic to both dogs and cats by the ASPCA. The toxic principles are genipposide and gardenoside, causing mild vomiting and/or diarrhea and hives if ingested. This is one of the clearest examples of why the “jasmine” name alone tells you nothing about safety — Cape jasmine’s white, fragrant flowers look similar enough to true jasmine that the shared name causes real confusion.
Is Paraguayan Jasmine Toxic?
Yes, seriously so. Paraguayan jasmine (Brunfelsia species) is toxic to dogs, cats, and horses. The toxic principle, brunfelsamidine, causes tremors and seizures that can persist for several days, along with vomiting, diarrhea, hypersalivation, lethargy, incoordination, and coughing — a notably more severe and prolonged symptom profile than the mild digestive upset associated with many “non-toxic plant, eaten in excess” scenarios. This is arguably the most dangerous plant on this list relative to how casually the “jasmine” name gets used in garden centers and online plant marketplaces; it’s also sold under names like Yesterday-Today-and-Tomorrow and Lady-of-the-Night, which don’t include “jasmine” at all and add another layer of identification risk.
The “Confederate Jasmine” Name Trap
This deserves its own warning because the risk isn’t about a single plant — it’s about two plants sharing one common name with opposite safety profiles. “Confederate jasmine” most often refers to Trachelospermum jasminoides (non-toxic, covered above), but in some regions the same common name — along with “yellow jessamine” — is applied to Gelsemium sempervirens, an unrelated, highly toxic plant containing potent neurotoxins from the Gelsemiaceae family. If you’re buying or already have a plant labeled “Confederate jasmine” and pets have access to your garden, confirm the botanical name is Trachelospermum jasminoides before assuming it’s safe.
How to Confirm What You Actually Have
Check the plant tag or receipt for a botanical (Latin) name rather than relying on the common name alone — this single step resolves most of the confusion above. If you don’t have that information, symptoms in a pet that has chewed on the plant should be treated as a potential poisoning regardless of which “jasmine” you believe you have; contact a veterinarian or animal poison control rather than trying to identify the plant first.
What Doesn’t Work
Assuming a plant is safe because a nursery, neighbor, or online forum called it “jasmine” does not work as a safety check, given how many unrelated and differently-toxic plants share that name. Similarly, treating all “jasmine” plants as equally risky and avoiding them entirely isn’t necessary either — several of the most commonly grown types (true jasmine, star jasmine) are genuinely non-toxic. The name itself just isn’t informative either way without the botanical name attached.
Frequently Asked Questions
Is jasmine safe for cats?
It depends entirely on which plant you have. True jasmine (Jasminum species) and star jasmine (Trachelospermum jasminoides) are non-toxic. Cape jasmine and Paraguayan jasmine are toxic. Madagascar jasmine (Stephanotis) has conflicting reports. Check the botanical name to know for certain.
What should I do if my dog ate jasmine?
Identify the botanical name if possible, then contact a veterinarian or animal poison control — especially urgently if it’s Cape jasmine, Paraguayan jasmine, or an unconfirmed plant, since these carry real toxicity risk.
Is jasmine essential oil safe around pets?
Essential oils are concentrated differently than the raw plant and carry their own separate safety considerations for pets, including respiratory sensitivity in cats specifically — this is a distinct question from raw plant toxicity and worth researching separately before diffusing any essential oil around animals.
Are jasmine flowers more or less toxic than the leaves?
For Stephanotis specifically, incident data shows leaves and stems account for the large majority of reported poisoning cases, not flowers. This pattern isn’t necessarily true for every plant on this list, so it shouldn’t be treated as a general rule beyond that specific species.
