Short answer: A white poppy is a symbol of remembrance for all victims of war and a commitment to peace and non-violent conflict resolution, often used to highlight the human cost of war beyond national or military identities. Details and context

• Origin and purpose: The white poppy was introduced in 1933 by the Women’s Co-operative Guild and is now associated with the Peace Pledge Union. It is worn as a reminder of the suffering caused by war and as a call to pursue peaceful, non-violent solutions to conflicts [reliable sources describe its origins and purpose].
• What it stands for:
  • Remembrance: It honors all victims of war, including civilians, refugees, and combatants from all nations, not limited to a single country or group [remembrance for all victims].
  • Peace and anti-militarism: It explicitly critiques militarism and the glorification of war, urging a shift away from war as a means of resolving disputes [peace and anti-militarism].
  • Commitment to nonviolence: It emphasizes working toward peaceful resolutions and preventing future wars [commitment to peace].
• How it differs from the red poppy: The red poppy (associated with Remembrance Day in many Commonwealth countries) memorializes military personnel and is traditionally tied to national service remembrance, while the white poppy broadens remembrance to all war victims and foregrounds peace-building [comparative note].
• How it’s worn: People wear a white poppy, sometimes alongside a red poppy, to denote both remembrance and a commitment to peace and nonviolence, depending on personal or organizational messaging [wearing guidance varies by group].
• Public discussion: The white poppy often generates public debate about remembrance, politics, and the appropriate scope of commemoration, reflecting ongoing conversations about how societies remember and respond to war [public discourse].
