Setsubunso festival Ogano

Setsubunso is in the winter aconite family, an Eranthis plant. But unlike most other winter aconite that have yellow flowers, the Japanese species is a white flower. A beautiful delicate white flower, with a circle of yellow around a purple cluster in the center. Sometimes in English winter aconite are also called winter hellebore, as in Christmas Roses. They are also sometimes called winter wolf’s bane in English, but again the Japanese winter aconite are quite different to most other Eranthis. Eranthis belongs to the buttercup family.
