In Japan, they are known as higanbana.
Lycoris holds a special place in Japanese culture. Its blooming period coincides with Autumnal Equinox Day, which this year we celebrated on Tuesday, September 22. Higan means "other shore" in Japanese. That is why higanbana is firmly associated with this holiday, because on the Day of Autumnal Equinox it is customary to visit the graves of ancestors who come to the world of the living, and the rest of the time are on the "other shore".
The Japanese believe that higanbana grows along the road that leads a person to rebirth after death. Well, if you are a fan of anime or manga, you must have seen these flowers.
Just as the sakura is a symbol of the coming spring, the lycoris is a harbinger of fall. By the way, a working omen - it's not so hot anymore. We are waiting for the fall coolness and red maples!
