All Saints Day is a celebration of the dead. It stems from the Anglican and Catholic tradition as a celebration of former saints.
This day follows Halloween and it is a day of feasting and cut flowers. Families take flowers to the graves of their loved ones. As this is a celebration rather than a mourning flowers tend to be an array of colour.
The other name All Souls Day represents a celebration of flowers for the bones.
Mostly celebrated in Europe and the United States we see increased prices on the Dutch Auction during this period due to supply and demand.
