Difference between common poppy and long-headed poppy?

The common poppy (Papaver rhoeas) is typically characterized by its bright red flowers and is often found in fields and meadows, while the long-headed poppy (Papaver dubium) features elongated seed heads and usually has yellowish or orange flowers. Common poppies are known for their association with remembrance and are often seen as a symbol of World War I, whereas long-headed poppies are more commonly found in disturbed soils and can be considered a weed in some areas. Both species belong to the same family but differ in habitat preferences and morphological features.
