In ancient times, when the wanderer wanted to travel far, he would first plant some grass, hoping that when the mother looked at these flowers, she would be able to alleviate her thoughts about her children and forget her worries.

"Literati of the past have also often used the theme of Xuancao chanting, so Xuancao has become a flower symbolizing mother in China.

But the grass here must refer to the yellow cauliflower in the vegetable field, not the grass flowers in the flower bed. In addition to the yellow cauliflower can be eaten, most of the grass is not edible! Because orange and orange-red grass contains a lot of colchicine, even if it is scalded and scalded in hot water, it cannot be eaten. If you accidentally eat it, it will irritate the stomach and respiratory system, and it will also have dry mouth, diarrhea, and dizziness, so remember not to eat Xuancao!
