What does the red poppy flower represent England?

Answer 1

The symbol is based on the poppies that grew in the Flanders region of France, an area of particularly brutal battle in World War 1, and subsequently the site of a famous military cemetery; it was adopted by the British and Canadian Legions, as a memorial symbol of the veterans of World War 1.

In the US., with the advocacy of Moina Michael, the American Legion and the Veterans of Foreign Wars adopted the symbol and expanded the use of it, to include fund raising efforts for disabled veterans. Under this program, a small, red paper poppy, to be displayed on shirt or blouse, was given in thanks, to each contributor. The symbolic red poppy also has a similar history in Australia, New Zealand, and France.

Answer 2

The actual flower of England is the Rose. However, Red Poppies are worn in the week around Rememberance Day (11th of November). This is done to mark the anniversary of the end of World War I, and in respect to soldiers who have died in subsequent wars. It is a reference to the poppies which grew in the battlefieds of Belgium and France, where thousands of soldiers were killed (unlike World War II, fighting was very concentrated and thousands of soldiers died in the same battlefields) On the 11th November, two minutes of silence are held at 11am, the time when the Armistice was signed.
