"Higan-bana" means the flower which blooms around Higan (the autumnal equinox) and its flowering season is about the middle of September.
Its flower buds in the soil know their flowering time by sensing only the seasonal change of temperature. The flower stalks emerge from the ground before the leaves and its delicate flowers bloom in the form of radial clusters simultaneously.
When the flower stalks disappear after flowering, the leaves grow out and remain green over the winter. In early summer, when other plants start growing leaves, the leaves of Higan-bana die and the above-ground part of this plant is no longer visible.
Instead of producing seeds, this plant reproduces by making its bulbs in the soil for multiplication. The individuals in the same colony are genetically identical, and so they have similar flowering periods, flower size and color, and grass height.
