This kind of flower is called oleander, which is very common on roadsides, parks and high-speed green belts. In daily life, many people don't know about oleander and its toxicity.
The leaves of oleander are like willows, and the red flowers are burning, which is better than peach blossoms. Corolla is pink to crimson or white, with a special fragrance. Flowering from June to 10, it is a famous ornamental flower. It looks so beautiful, but its flowers, leaves and branches are poisonous. Scientists have found that this plant contains more than one toxin. The toxicity of oleander still exists after drying up, and the smoke produced by burning oleander is also highly toxic. A few or 10-20 leaves can have a bad effect on adults, and one leaf can kill a baby. For animals, the lethal dose is as low as 0.5 mg per kilogram of body weight. Most animals have bad or fatal reactions to oleander. Since oleander is so poisonous, why does it appear in parks and green belts?
Oleander also has another name, called "environmental guardian". Nerium oleander has the ability of smoke resistance, dust prevention, virus prevention, air purification and environmental protection. Even if the whole body is covered with dust, it can still grow vigorously, so this plant is very common in high-speed green belts.
It is recommended not to pick at will, especially those plants that have never been seen, unknown and particularly beautiful.
In nature, many plants tend to have higher values and greater toxicity in order to survive and evolve. Parents should give their children this common sense from an early age, and all preventive education should start with dolls.
