The orange and citrus industry in Riverside, California, is closely intertwined with the region’s development and economic success. It all began when Eliza and Luther Tibbets introduced a successful variety of sweet orange, the Washington navel orange, to the area in the 1870s. This marked the beginning of a flourishing citrus industry that transformed Riverside into a citrus empire. The Mediterranean-like climate and fertile soil of the region proved ideal for growing oranges and other citrus fruits. The citrus industry played a pivotal role in shaping Riverside’s economy, culture, and landscape, leading to the establishment of citrus groves, packing houses, and marketing strategies that contributed significantly to the city’s growth. Today, Riverside’s legacy as a citrus-producing hub is commemorated through historical landmarks and events that celebrate this heritage.
