绿化苗木除了美化环境其实还有净化空气，净化土壤，净化水体等作用，其实还有一个小众的功能，也是比较少用的，就是我们种植的一些苗木，是有食用价值和药用价值的，例如食用桃花可以泡水洗脸、例如冬青也有药用价值，例如有些植物不可食用是有毒的，但是可以入药。
In addition to beautifying the environment, greening seedlings can also
purify the air, soil and water. In fact, they also have a minority
function, which is also less used. Some seedlings planted by us have
edible value and medicinal value. For example, peach blossom can be
soaked in water to wash face. Holly also has medicinal value. For
example, some plants are not edible and poisonous, But it can be used as
medicine.
