The
Tudor rose is a product of the Wars of the Roses (1455-85). Each side
adopted a particular rose as a sign of thier allegiance. After defeating
the Yorkists at the battle of Bosworth Field (1485), Edmund Tudor, the
head of the Lancastrians, became Henry VII, and adopted as his sign a symbol of
the union of the two side. The Tudor rose thus contains the white rose of
the Yorkists inside the red rose of the Lancastrians
