Popular Houseplants: Care + Pet Safety, Verified

Some links on this page may be affiliate links — they never change our advice.

Every popular houseplant guide on Leafmend has been written the same way: we read the university extension page for the species, quote it, and cite it; then we check ASPCA’s database for pet toxicity, quote it verbatim, and put a clear callout at the top of the article — green for “non-toxic”, red for “toxic”. If ASPCA doesn’t have an entry, we don’t ship a toxicity claim. (How we research: How We Research.)

Pet-safe houseplants (ASPCA non-toxic to dogs and cats)

For households with pets, these are the species ASPCA’s database explicitly clears.

• Spider Plant — Chlorophytum comosum. The classic recommendation for pet households. Easy, propagates from plantlets, tolerates low light.
• Calathea — Calathea spp. (often reclassified as Goeppertia). Showy patterned leaves; fussier about humidity than other pet-safe options.
• Phalaenopsis Orchid — Phalaenopsis sp. (Moth Orchid). The supermarket orchid — flowers last months, repeat-blooms annually.

Toxic houseplants — keep out of reach of pets

ASPCA lists these as toxic to dogs and cats (some to horses too). Each guide opens with a red pet-warning callout that quotes ASPCA’s exact clinical signs.

• Monstera Deliciosa — Monstera deliciosa (also “Swiss Cheese Plant”). Insoluble calcium oxalates.
• Snake Plant — Sansevieria trifasciata / Dracaena trifasciata. Saponins.
• Pothos — Epipremnum aureum (also “Devil’s Ivy”, “Golden Pothos”). Insoluble calcium oxalates.
• Peace Lily — Spathiphyllum. Insoluble calcium oxalates. Not a true lily; less severe than Lilium, but still toxic.
• Heartleaf Philodendron — Philodendron hederaceum. Insoluble calcium oxalates. Toxic to horses as well as dogs and cats.
• Aloe Vera — Aloe vera. Saponins and anthraquinones. ASPCA notes the inner gel itself is considered edible; whole-leaf chewing is the risk.

Always cross-check ASPCA before bringing home a new plant

We cover the popular species in detail here, but every household and every species is different. The ASPCA Toxic and Non-Toxic Plants database is the authoritative source — search by common name or scientific name before buying. We followed exactly that process to verify each callout on this site.

How to use this hub

A common path through the system:

1. Pick a species above — read the full care guide for the plant you have (or are about to buy).
2. Master the basics — every species guide links into the same Houseplant Care Basics for light, water, soil and fertilising fundamentals.
3. Diagnose problems — if a leaf is doing something it shouldn’t, the Troubleshooting hub maps symptoms to causes.
4. Defend against pests — the Houseplant Pests hub covers prevention and least-harm management for fungus gnats, spider mites and mealybugs.
5. Multiply and re-pot — when you’re ready, the Propagation and Repotting hub has the rest.

Methodology

See our How We Research page for the full disclosure of sources, voice, and what we will and will not claim. The short version: every toxicity claim on this site is ASPCA-sourced and gated through explicit owner confirmation — we do not invent it, we do not approximate it from another database, and we do not paraphrase it. If ASPCA hasn’t covered a species, the species doesn’t get a toxicity claim on Leafmend.
