The state flag consists of alternating red and yellow rays that represent the 13 original colonies and the western setting sun. The red and yellow are based on the colors of the Spanish flag that Coronado carried into the region. The bottom half of the flag is the same color blue found in the U. S. flag. The copper star identifies Arizona as the largest copper producing state in the union.

The pure white waxy blossom of the giant saguaro cactus was designated the state flower of Arizona in 1931. It blooms on the tips of the saguaro cactus during the May and June months.
