Who has the red poppy as its countries symbol?

The red poppy is a symbol of remembrance and is primarily associated with several countries, particularly the United Kingdom, Canada, Australia, and New Zealand. It commemorates soldiers who died in combat, especially during World War I. The flower became a symbol largely due to the poem "In Flanders Fields" by John McCrae, which references poppies growing on the battlefields. Today, red poppies are worn during Remembrance Day ceremonies in these countries to honor fallen service members.
