The Grand Floral Parade is the centerpiece of the festival and the second largest all-floral parade in the United States[5][6][7] after the Tournament of Roses Parade.[5][7] More than 500,000 spectators line the route, making this flower parade the largest single-day spectator event in Oregon.[6][8] The first parade, in 1907, was called the Rose Carnival, but eventually came to be known as the Rose Festival Parade[9] and later still the Grand Floral Parade.
