Did you know?
Venture into the Arizonan desert on a May or June morning and you may see the saguaro in bloom. For many of our readers (such as those living in Arizona and southeastern California), this sight - and the word saguaro - won't be anything new. Or perhaps you know this emblem of all things Southwestern simply as the "giant cactus." The word saguaro originated in Ópata, a language spoken by peoples of the Sonoran Desert region of Mexico. It came into English by way of the Spanish spoken by the Mexican settlers of the American West. The very saguaros we see today may well have been around when the word was first noted, some 150 years ago - this amazing cactus can live for up to 200 years.
