2. Chrysanthemum, also known as Folium Artemisiae Argyi, is a compositae plant and a common vegetable, which is cultivated in many places in China. In Europe, people will use chrysanthemums as flower beds, and the flowers are yellow. I like growing up in a cold environment, but I can't stand the high temperature. It is also a diurnal plant, so it will blossom and bear fruit soon.
