The girl without sorrow, a perennial herb of Hemerocallis in Liliaceae, has a long history of cultivation in China. Folk also known as anti-anxiety flower, yellow grass, day lily, deer onion, deer sword, suitable person, day lily, day lily and so on. Because the buds and stamens are lemon-colored, foreigners call them "lemon daylily".

I also checked it carefully, and it turns out that a girl who is not sad is really called day lily.

Last time I visited the botanical garden, I saw a girl who was not sad, also called day lily. The picture is like this (below). I thought it was a non-flowering weed.

Satisfied adoption
