199 Poisonous Plants to Look Out For

poisonous-flowers-rd2.pngToday, a guest blog from ProFlowers. The presentation below was sent to me by Taylor Poppmeier, one of the people involved in preparing it, so I’m using it with permission. It’s quite interesting, although unfortunately not searchable, nor is the botanical name used, so in many cases, it’s hard to be sure which plant is being referred to (I can think of 4 different plants known as “bottle tree” for example). If you’re concerned about potentially toxic plants in your home and garden, though, you’ll probably find it very useful.

I’ve placed the table in this blog, but if you prefer to go to the original site, here is the link:

199 Poisonous Plants to Look Out For
By Erica Daniels

While plants and flowers are a great way to decorate, not every plant is safe for your home. We know poison oak shouldn’t be touched, and to keep poinsettias away from our pets, but did you know some of your favorite blooms may have toxic properties as well?

We’ve rounded up a list of almost 200 common poisonous plants so you can be sure you’re picking the safest options. Most of these plants are safe to grow and keep in your home, but should be avoided if you’re concerned of accidental ingestion from a hungry pet or curious child. Look through the list of plant names and make sure no one in your home is at risk.


Explanation of toxicity levels
Keep in mind toxicity levels can vary based on your level of contact with a plant. For example, a plant like black henbane is fatal even in low doses, whereas some plants you need to consume a large amount to experience side effects.

Here is a breakdown of the four levels:

Major toxicity: These plants may cause serious illness or death.
Minor toxicity: Ingestion may cause minor illnesses such as vomiting or diarrhea.
Oxalates: The juice or sap of these plants contains oxalate crystals, which can cause skin irritations or more serious ailments like throat swelling, breathing difficulties, and stomach pain.
Dermatitis: These plants may cause a skin rash or irritation.
With all four toxicity levels, it’s advised that you contact the Poison Control Center (800-222-1222) or your doctor.

If you notice that some common fruits are on the list, there’s no need to rush to toss out your last grocery run. Many toxic parts of plants such as cherries, apricots and peaches aren’t the fruits themselves, but other parts like the stem, leaves and seeds. These parts we never consider eating, so we never come in contact with them.

Special care for children and pets
Most plants we would never think to eat or touch, but for small children and pets that are unaware of harmful side effects, it’s recommended you keep them out of arm’s reach. For example, a peace lily is a very popular indoor plant given its ability to clean the air in your home. But it’s also highly toxic for cats and dogs, so try to keep the plant on a high shelf.
