Bellflower is a city located in southeast Los Angeles County, California, in the Los Angeles metropolitan area. It was founded in 1906 and incorporated on September 3, 1957. As of the 2020 census, the city had a total population of 79,190, up from 76,616 at the 2010 census. This made it the 65th most densely populated city in the United States, of cities over 50,000 residents (and the 8th most densely populated city in California).The site was formerly rich farmland watered by artesian wells and floodwaters of the now-contained San Gabriel River. In 1906, F.E. Woodruff, a local real estate investor, founded the first municipality on the site, which was named Somerset in 1909 when a post office was established there. However, the proponents of the name 'Bellflower' claimed that the US Post Office Department rejected the name 'Somerset' to prevent confusion with Somerset, Colorado.
