We celebrate St George's Day on the 23rd April. If we're in St George we can wear red to school!
St. George is the patron saint of England.
The national flower of England is the rose. The flower has been adopted as England's emblem since the time of the Wars of the Roses - civil wars (1455-1485) between the royal house of Lancaster (whose emblem was a red rose) and the royal house of York (whose emblem was a white rose).
