Because flowers and leaves can't meet, Lycoris radiata has a flower called "heartless".

Galanthamine extracted from the root of Lycoris radiata can be used to treat polio, which has been used abroad, and experts in China are also doing in-depth research to develop drugs for the benefit of mankind. Because Lycoris radiata often blooms near the cemetery, the color is bright red as blood, and the flowering period is near the autumnal equinox (Japanese sacrificial festival), Lycoris radiata leaves and flowers and never meet each other, so in Japanese legend, this flower has the ominous color of death and separation, and is mostly used for funerals.
