Papaver rhoeas
Papaver rhoeas, with common names including common poppy, corn poppy, corn rose, field poppy, Flanders poppy, and red poppy, is an annual herbaceous species of flowering plant in the poppy family Papaveraceae. It is notable as an agricultural weed (hence the common names including "corn" and "field"). Especially in the UK, it is used a symbol of remembrance of the fallen soldiers and other military, during World War I and thereafter.
