Why did they choose poppy for remembrance day?

The poppy was chosen for Remembrance Day due to its association with World War I, particularly the battlefields of Flanders, where the bright red flowers famously grew amidst the devastation. The poem "In Flanders Fields," written by Lieutenant Colonel John McCrae, highlighted this imagery, symbolizing the sacrifice of soldiers who died in battle. The Royal British Legion adopted the poppy as a symbol of remembrance in 1921, and it has since become a poignant emblem honoring all military personnel who have lost their lives in conflict.
