Poisonous House Plants can put children or pets at risk. Learn how to handle and recognize a poisonous indoor plant. Which indoor plants are toxic for humans and pets?
A lot of the beautiful house plants we love to grow are poisonous or can cause severe allergies in pets and humans. You don't have to avoid all of these plants if you know how to handle them with care and if you are not allergic to them.
The milky sap of plants like Poinsettias or Crown-of-thorns plant can cause skin irritations and allergic reactions. If you handle these plants with care they are safe to have in your home.
This is the Crown-of-thorns plant (Euphorbia milii). If the plant gets injured it excretes a milky sap that is poisonous.
Of course this is different if you have small children or pets like cats, dogs, rabbits, guinea pigs or pet birds that are allowed to roam the house freely. These pets sometimes like to nibble on leaves, stems or twigs and expose themselves to the toxins. Check this page for house plants safe for cats and other pets.
Children are often tempted by colorful fruit or berries and might eat some without anybody noticing. That is just too dangerous!
One such plant is the Winter or Christmas Cherry. This toxic plant has very attractive orange berries . These berries are of course very attractive for children and nearly look nearly like small cherry tomatoes. This is maybe a poisonous house plant I would not recommend to have around if you have small children! It is just not worth taking the risk.
Euphorbiaceae - Poinsettia (Euphorbia pulcherrima),
Crown-of-thorns or Christ plant (Euphorbia milii), Croton (Codiaeum
variegatum), Cattail (Acalypha)
Araceae - Dumb Cane (Dieffenbachia), Chinese Evergreen (Aglaonema), Flamingo Flower (Anthurium), Swiss Cheese Plant (Monstera), Calla Lily (Zantedeschia)
Amaryllidaceae - Amaryllis (Hippeastrum), Tulips, Narcissi, Hyacinths, Clivia
Some plants are not toxic but they can cause allergies in sensitive people. The allergies can be caused by the sap or the tiny hairs on leaves or stems. A prime example for this is the German Primrose (Primula obconica).
Cyclamen have a substance in their bulbs that can cause allergies but you would seldom get into contact with it.
