The Pasadena Rose Parade traditionally features floats covered with flowers and other natural materials.
Officially called the Tournament of Roses Parade, the event takes place in Pasadena, California, on New Year's Day. Its floats are famous for using fresh flowers, seeds, leaves, bark, and other plant materials to create detailed images and designs.
The parade began in 1890, organized by the Pasadena Valley Hunt Club as a way to showcase Southern California's mild winter climate. It later became associated with the Rose Bowl college football game, which is played on the same holiday and is organized by the Tournament of Roses Association.
The parade is normally held on January 1, but a long-standing rule moves it to January 2 when January 1 falls on a Sunday. This prevents conflict with Sunday church services and is why some editions do not occur on New Year's Day itself.
