In Japanese, this phenomenon is referred to as "Himawari wa yoru ni saku" or "Sunflowers bloom at night."

During the day, sunflowers face the sun, maximizing their exposure to sunlight and facilitating photosynthesis. However, as the sun sets, the plant's flowers and leaves begin to move, often in a more relaxed and downward position.
This nocturnal movement is thought to be an adaptation to conserve energy and protect the plant from potential threats. By moving their flowers and leaves downward, sunflowers may be able to reduce their visibility to nocturnal herbivores or protect themselves from excessive moisture.

The phrase has been used in literature and poetry to symbolize the mysterious and often overlooked aspects of nature.
