Many houseplants can be toxic if your pets or children ingest them. While most pets and children do not eat houseplants, if yours are inclined to do, use this resource to help identify them. There are several types of toxins that can be present in houseplants such as solanine, oxalates, and cardiac glycosides, which may cause nausea, vomiting, irriation, or worse. There are over 700 common houseplants that can contain toxins, but here is a list of the 20 common houseplants.

Keeping Toxic Houseplants Out of Reach

Growing houseplants on high surfaces, such as a trailing plant cascading down from atop a bookcase or hutch, will keep them safely out of reach of dogs. Cats, however, are a bit more challenging as their agility allows them to scale seemingly even the most inaccessible locations.

Cats tend to be more attracted to plants with lacey or grass-like foliage so selecting plants with large, bold or heavier leaves may discourage cat browsing.
