16 Most Toxic Mushrooms Found Easily in Garden
Plants You Should Never Grow Indoors
Botanical Name: Nerium oleander
Oleander is a beautiful but highly toxic flowering shrub. Its presence indoors or probably on a balcony or patio can pose a significant health risk, especially if you’re a parent, as all its parts contain cardiac glycosides.
2. Castor Bean Plant
Botanical Name: Ricinus communis
The castor bean plant has very attractive foliage, but it contains ricin, a deadly toxin. You should definitely avoid growing it around your house, and if you see it growing, remove it. It is said that 4 to 8 castor beans if ingested, can make a lethal dose for an adult.
3. Crown of Thorns
Botanical Name: Euphorbia milii
This succulent has one of the most long-lasting flowers, but it produces toxic latex sap, which can cause skin irritation and can even make you blind if it goes into the eyes. It’s a must NO if you have children at home; if not, the best position to grow is on a sunny windowsill.

Avoid growing it because this carnivorous beauty needs very high humidity and consistent prudent watering, making it a challenge for new plant parents or dry-air homes.
Botanical Name: Rhododendron
These beautiful flowering shrubs need cool temperatures and bright, filtered sunlight, conditions rarely found in most homes. This makes them high-maintenance houseplants and not only that, they are toxic.
6. Venus Flytrap
Botanical Name: Dionaea muscipula
This quirky carnivorous plant might seem like a fun conversation starter, but its specialized needs for sunlight, humidity, and insect prey make it difficult to thrive indoors, especially if you’re new to gardening.

8. Sago Palm
Botanical Name: Cycas revoluta
Botanical Name: Dieffenbachia
This houseplant is a favorite of many, but it truly lives up to its nickname. The sap can cause intense oral irritation – our suggestion is to avoid it if you have pets and kids. Otherwise, it is one of the easiest houseplants to grow!
