Noisy: In fact, many flowers can kill people, but everyone doesn't notice that there are actually many kinds of flowers that can't be kept indoors, among which hydrangea, cordate telosma, bauhinia, mimosa, oleander, tulip, narcissus, dripping Guanyin, evergreen mosaic, tiger thorn plum and so on are more common. Especially in the living room with small space, don't put it. The water dripping from Guanyin leaves is poisonous, and Rosa davurica and oleander are also poisonous plants, so special attention should be paid when breeding. The vines and shrubs of cordate telosma have milk and are oxygen-consuming flowers. Its photosynthesis is only in the daytime, and it also consumes a lot of oxygen. After stopping photosynthesis at night, a large amount of waste gas will be discharged, which smells fragrant, especially at night, which will make patients with hypertension and heart disease feel dizzy and depressed, and make their condition worse.
