The symbol of a poppy as a remembrance for Veteran's day started with World War I. A Canadian surgeon, John McCrae wrote a famous poem titled In Flanders Field. The war torn fields and bombing unearthed old seeds. The nurturing lime from destroyed buildings and nitrogen in the bombs created a perfect fertilizer for the red flowers native to northern Belgium and France. Due to the popularity of the poem the symbolism of poppies after Armistice signing, on November 11th 1918, spread worldwide and continues to this day.
