Why is "Hemerocallis" the mother flower of China?

The reason why daylily is a mother flower is that daylily is called mother in many ancient poems and has been passed down to this day. Meng Jiao wrote in "Poems of the Wanderer" that "the day lily has steps, and the wanderer travels all over the world. The loving mother leans against the hall door and doesn't see the day lily flowers, so as to praise maternal love. The earliest written records can be found in the book of songs, and Zhu noted that "grass is forgotten; Back, Beitang also. " .
