The plant's most common name the same in English and Spanish is an alternate form of the Spanish hierba buena meaning "good herb". The name was bestowed by pioneer Catholic priests of Alta California as they settled an area where the plant is native. It was so abundant there that its name was also applied to the settler's town adjacent to Mission San Francisco de Asís. In 1846 the town of Yerba Buena was seized by the United States during the Mexican-American War and its name was changed in 1847 to San Francisco after a nearby mission. Three years later the name was applied to a nearby rocky island; today millions of commuters drive through the tunnel on Yerba Buena Island that connects the spans of the San Francisco – Oakland Bay Bridge. _________________________ By docentjoyce This photo was taken on May 22 2011 in California US using a Panasonic DMC-FZ8. http://www.flickr.com/photos/docentjoyce/5748182243/ License Some rights reserved
