Voters approved the Florida state flag in 1900. The 13-cent Florida State Flag stamp (Scott 1659) displays two diagonal red bars on a white field. The seal of the state occupies the center of a white ground, and red bars extend from each corner towards the center, to the outer rim of the seal.
The state seal on the flag features a Native American Seminole woman scattering flowers, a steamboat, a cabbage palmetto tree, and a brilliant sun. Florida is represented as the land of sunshine, flowers, palm trees, rivers, and lakes.
