Title: Saguaro
Content:  Arizona made the saguaro blossom its territorial flower on March 13, 1901, and on March 16, 1931, it became the state flower. The saguaro is often used as an emblem in commercials and logos that attempt to convey a sense of the Southwest, even if the product has no connection to Arizona or the Sonoran Desert. For instance, no naturally occurring saguaros are found within 250 mi of El Paso, Texas, but the silhouette is found on the label of Old El Paso brand products. Though the geographic anomaly has lessened in recent years, Western films once enthusiastically placed saguaros in the Monument Valley of Arizona, as well as New Mexico, Utah, and Texas. The Dallas, Texas-based band Reverend Horton Heat pokes fun at this phenomenon in their song "Ain't no Saguaro in Texas."
