Field of Poppies — Vincent van Gogh. Nearly a century after World War I ended, millions of people in the United Kingdom, Canada, France, Belgium, Australia and New Zealand don the red flowers every November 11 (known as Remembrance Day or Armistice Day) to commemorate the anniversary of the 1918 armistice.
Americans don’t typically wear poppies on November 11 (Veterans Day), which honors all living veterans. Instead, they wear the symbolic red flower on Memorial Day to commemorate the sacrifice of so many men and women who have given their lives fighting for their country. — History.com
