I think poppy wearing is a very British thing. I know in France cornflowers are the symbol of remembrance and are worn in a similar fashion to the red poppies. Some other countries like the US wear poppies but not to the national scale of the UK. In early November all television personalities, reporters, politicians, etc are all wearing poppies.

"Think of all the beauty still left around you and be happy". Anne Frank
