6. Oleander
The Oleander (Nerium oleander) is another gorgeous but poisonous plant that should be admired from afar! You can typically find it in parks, gardens, and even roadsides, and it will be easy to spot thanks to its delicate and charming white, pink, or red blossoms.
Don’t be fooled by its innocent looks, because this poisonous shrub can immediately trick you! All parts of this poisonous plant are packed with compounds called cardiac glycosides, which can cause dizziness, nausea, irregular heartbeat, and even severe heart complications if ingested.
Experts consider oleander to be one of the deadliest ornamental plants since even a tiny amount can be harmful to humans and animals. While it can add a gorgeous touch to any space, you’d better keep it at a safe distance!
