While in the United States, the flower is usually regarded as positive and cheerful, in some countries of Europe, Korea and in Japan, white chrysanthemums are symbolic of death and are only used for funerals or on graves.
In China, white chrysanthemums are symbolic of lamentation, while in some other countries, of honesty.
All Saints' Dayis a feast celebrated on November 1 in Western Christianity.
In terms of Roman Catholic theology, the feast commemorates all those who have attained the beatific vision in heaven, while the next day,
All Souls' Dayis the Commemoration of all the Faithful Departed (from the Latin Commemoratio omnium Fidelium Defunctorum), Day of the Dead (in Mexico), and Defuncts' Day (in Hungary, Romania, France, Italy, and Ecuador).
In this part of the world where I live, the tradition is to visit the graves of deceased relatives where we lay flowers, mostly Chrysanthemums, and light candles.
