As Southern California recovered from the collapse of the cattle industry in the 1860s, the arrival of railroads—attacked by newspapers as the greedy “octopus”—and the expansion of citrus agriculture transformed the struggling region into a vast, idealized, and prosperous garden.

New groves of the latest citrus varieties and new towns like Riverside quickly grew directly along the tracks of transcontinental railroads. The influx of capital, industrial technology, and workers, especially people of color, energized Southern California and tied it more closely to the economy and culture of the United States than ever before.

Benjamin Jenkins’s Octopus’s Garden argues that citrus agriculture and railroads together shaped the economy, landscape, labor systems, and popular image of Southern California. Orange and lemon growing boomed in the 1870s and 1880s while railroads linked the region to markets across North America and ended centuries of geographic isolation for the West Coast. Railroads competed over the shipment of citrus fruits from multiple counties engulfed by the orange empire, resulting in an extensive rail network that generated lucrative returns for grove owners and railroad businessmen in Southern California from the 1890s to the 1950s.
