1、 Strong aroma

Although Lingxiao flower has no toxicity, it has a strong fragrance. If it is close for a long time and smells the fragrance all the time, it will cause brain damage, especially when children are still in the stage of growth and development. The fragrance of flowers is more irritating to children

2、 Pollen allergy

Lingxiao flower will bloom at the flowering stage and emit pollen. At this time, if the pollen accidentally invades into the eyes and nasal cavity, it may cause redness and swelling of the eyes and poor nasal breathing. If there are people with allergic symptoms at home, it is not recommended to keep Campanula at home

3、 Destroy the wall

Campanula is a climbing plant. It will climb up along the wall, which may cause damage to the wall and make the wall not smooth and flat. Lingxiaohua also climbs to the roof, which may be adsorbed on the tiles on the roof. When the wind blows, it may fall down with the tiles

4、 Compete for space

The growth ability of Lingxiao flower is very strong, and its root system will spread and grow. It will seize the growth space with other plants, and the restriction will affect the growth of other plants, resulting in poor growth of other plants. They may also climb to other people's homes nearby, which may have some impact on other people's lives. During the maintenance of Lingxiao flower, it is necessary to trim regularly, cut off some long and dense branches and some redundant roots

5、 Attract mosquitoes

The luxuriant branches and leaves of the flowers may cause a great impact on people's life and attract mosquitoes
