What are the common varieties of poisonous flowers?

Nowadays more and more people are growing flowers. Placing a few pots of flowers on a balcony or in a room can purify the air and beautify the environment, and it can also cultivate one's character, letting people experience endless joy in the process of growing flowers. But as everyone knows, some flowers are inherently toxic, and smelling them for a long time can have adverse effects on people. Below are some common poisonous flowers, so everyone should pay attention to the relevant matters when planting them to avoid plant poisoning.

Oleander

It blooms in spring, summer and autumn every year. It is a flower that can be enjoyed and used medicinally, but can also poison people. Its stems, leaves and even flowers are toxic, and if its scent is smelled for too long, it can make people drowsy and reduce their mental acuity. The milky white sap it secretes can cause poisoning if swallowed by mistake.

Poinsettia

The whole plant is toxic, especially the white sap in the stems and leaves, which can irritate the skin, causing redness and swelling and allergic reactions. If the stems or leaves are eaten by mistake, there is a risk of poisoning and death.

Narcissus

Growing it at home is generally no problem, but do not break its bulbs, because they contain lycorine, and eating them by mistake can cause vomiting and enteritis; the sap of the leaves and flowers can cause skin redness and swelling, and be especially careful not to get this sap into your eyes.

Datura flower

Also known as belladonna flower, it is common in rural areas south of the Yangtze River, and children who eat it by mistake will be poisoned.

Night-blooming jasmine

At night, after it stops photosynthesis, it releases a large amount of waste gas. This waste gas smells very fragrant, but it is harmful to human health. If it is kept indoors for a long time, it can cause dizziness, coughing, and even asthma and insomnia. Therefore, place night-blooming jasmine indoors during the day, and move it outdoors in the evening.
