Tropical Poisonous House Plants to Beware!

Poisonous House Plants

Welcome to My Poisonous house plants page, I hope That this list of poisonous house plants and dangerous plants will be informative and help you identify and protect your family and pets.

They can be very beneficial in our lives but we must avoid them as much as possible or be cautious especially with Small children and animals.

They purify and renew our stale indoor air by filtering out toxins, pollutants, and the carbon dioxide we exhale - replacing them with life sustaining oxygen.

However, many of our most popular House plants come from tropical climates where the highest percentage of poisonous plants live, that’s why its important to have this list of poisonous house plants and toxic house plants to keep you aware of any dangerous plants you may have in your home or garden..

Toxic houseplants are a problem if you have young kids or pets in the house they accidently eat them, pick their leaves or rub up against them.

Some toxic plants will only cause an annoying skin rash, but others, if ingested, could be deadly to adults, children and our cute little pets.

It's best to know which Poisonous House Plants you should avoid, but if you want to play it safe stick to African Violets, Ferns, Gardenia, Jades, or a nice rubber tree also silk flowers are great too.
