Toxic to Pets

Magic Flower

Achimenes hybrids

No reported toxicity in any Achimenes species to cats, dogs, or humans. The plant is not edible and there is no reason to encourage snacking on it, but it is not considered dangerous.

The Asian triploid and tetraploid varieties contain beta-asarone, which is a procarcinogen - the FDA banned these from food use in 1968. The North American diploid variety does not contain beta-asarone. As a houseplant it is not something you would be ingesting, but if you have pets or children who chew on plants, exercise caution. The ASPCA does not explicitly list it in their toxic plant database, but the beta-asarone content in Asian varieties warrants keeping it out of reach.

Miniature Sweet Flag

Acorus gramineus

Not listed as toxic by the ASPCA for cats, dogs, or horses. Like its relative Acorus calamus, the Asian varieties of Acorus gramineus may contain low levels of asarone compounds, but at concentrations far lower than A. calamus and not considered a practical health risk for pets encountering the plant.

Crinkle-Leaf Plant

Adromischus cristatus

Conflicting information exists online. The ASPCA does not list Adromischus in their toxic plant database, and several pet-focused plant sources classify it as safe. Some succulent care sites caution that it may be mildly toxic if ingested. As a precaution, keep it out of reach of pets and children, and consult a vet if ingestion occurs.

Plover Eggs

Adromischus festivus

The ASPCA does not list Adromischus as toxic. Multiple pet-focused sources classify it as safe for cats and dogs, noting that any ingestion might cause mild stomach upset at most. Some general succulent care sites are more cautious and recommend keeping it out of reach as a precaution. No documented serious toxicity cases exist for this genus.

Zebra Basket Vine

Aeschynanthus marmoratus

Non-toxic to cats, dogs, and horses. The ASPCA lists Aeschynanthus (Zebra Basket Vine) as non-toxic. As with any plant, ingestion may cause mild stomach upset, but no serious toxicity has been documented.

Variegated Century Plant

Agave americana

Mildly toxic to cats, dogs, and horses via saponins and calcium oxalate crystals. Can cause vomiting, diarrhea, and lethargy. The needle-sharp leaf tips are also a puncture hazard.

Queen Agave

Agave victoriae-reginae

Mildly toxic to cats and dogs via saponins and oxalates; can cause vomiting, diarrhea, and skin irritation. The terminal spine is sharp enough to puncture skin -- handle with care.

Chinese Evergreen

Medicine Plant

Aloe barbadensis

Toxic to cats, dogs, and horses per ASPCA. The saponins and anthraquinones in the outer leaf and sap cause vomiting, diarrhea, and lethargy. The inner gel is considered safe for human topical and internal use in moderate amounts, but large oral doses have been linked to digestive upset and electrolyte imbalances.
