Higanbana blooms around the O-Higan period
O-Higan is an observance to give thanks to origins and nature. O-Higan is a period of 7days includes 3 days before and after the day of Autumnal Equinox Day. During the O-Higan period, people visit the family grave at the cemetery to remember their past family members and gratitude their ancestors.
Since it blooms around O-Higan period, this flower is called Higanbana (Higan flower) and is also called Manjushage or Manjusaka, meaning “the flower blooming in heaven” in Sanskrit. Higanbana is associated with Buddhism and the flowers are often seen at temples or Japanese gardens.
The root of Higanbana is toxic. They are often grown at places surrounding rice fields so to drive out moles or rats.
