YouTube video

Poisonous indoor plants. You’re likely to see many of them in your home…

Children and pets can be poisoned by many common houseplants if ingested…

Some plants are dangerous than others, but it is good to know which ones to avoid…

… or to watch out for if you have children or pets.

Hear it from Bryce!

My two children and my dog share my home; and I have many plants, many of which are toxic…

By arranging poisonous plants in spots that neither my kids nor dog can reach…

… I’ve managed to keep everyone healthy and out of trouble so far. 

Aside from chewing on the leaves, my dog doesn’t get sick…

… when he lounges under a bird of paradise plant every day.

It’s a matter of caution…

You can find ways to keep plants, in particular those supposedly poisonous to humans…

… safe by displaying them in places where kids and pets cannot reach them, for example.

Parents and pet owners can easily display attractive plants that are safe for their pets and children…

… while keeping harmful plants out of reach.

Would you rather keep these 10 plants out of your home…

… if you have a cat that likes to climb on walls and nibble on plants?

It doesn’t have to be toxic, there are plenty of cat-friendly indoor plants, even succulents…


10 Poisonous Indoor Plants For Children And Pets

In general, plant toxicity can be separated into three categories:

  • Non-Toxic, (safe, not poisonous)
  • Caution, (mildly toxic)
  • Toxic, (dangerous, poisonous)

I recommend the following links if you want to learn more about a certain plant that is not mentioned in this article:

  • Check with the Poison Control Centre to see if any plants can be safe for human consumption.
  • To learn more about which plants are toxic or non-toxic for animals, please visit the ASPCA (American Society for the Prevention of Cruelty to Animals).
