Every Single Part Contains Poison
Oleander stands out as one of the most toxic plants you can grow in your yard, with poison present in absolutely every component.
The leaves, flowers, stems, roots, and even the nectar contain cardiac glycosides that affect the heart.
These dangerous compounds remain active whether the plant is fresh, dried, or burned.
Many people mistakenly believe only certain parts pose risks, but this assumption could lead to serious trouble.
Children have experienced poisoning after using oleander sticks as skewers for roasting marshmallows.
Even the smoke from burning oleander branches can cause respiratory problems and other health issues.
The sap that oozes from broken stems or leaves can irritate your skin and eyes on contact.
Some people develop painful rashes just from touching the plant while trimming or handling it.
Washing your hands thoroughly after any contact becomes absolutely essential.
Animals face similar dangers when they chew on branches or consume fallen leaves.
Dogs, cats, horses, and livestock can all suffer severe reactions from ingesting even small amounts.
Keeping pets away from oleander plants should be a top priority for any Arizona pet owner.
The concentration of toxins varies slightly depending on growing conditions and plant maturity.
However, no part ever becomes safe to touch without precautions or consume under any circumstances.
Treating oleander with the respect it deserves can prevent tragic accidents in your home.
