In Great Britain the red poppy is, of course, the flower most  firmly associated with the remembrance of members of the armed services who have died, or served, in wars.  Since 1921 the British Legion has produced and sold these early in November each year, in 2016 it was estimated that 40 million poppies would be sold.  However, in 2019 it seemed that fewer people were wearing poppies, possibly as a reaction against the way in which the Legion  has  aggressively over promoted poppies in recent years.
