Spanish Missionaries brought the olive tree to North America in the 1700's. The first olive trees were planted in California at the San Diego Mission by Franciscan monks in 1769. The trees were planted throughout California with the intention of producing oil, but the lower cost European olive oils won out. In the late 1800's, a housewife, Freda Ehmann and her son, Edwin began experimenting with new ways to market the olive, and she found success with the California style ripe black olives she produced.
farmers grow dozens of different olive types. The five most important California table-olive varieties are the Manzanillo, Sevillano, California , Ascolano and Barouni. The Manzanillo represents the most acreage, while the Sevillano and Ascolano are valued for their larger olive size. Olive-oil producers have planted large numbers of the Arbequina, Arbosana, Koroneiki, Frantoio, Mission , Manzanillo and Leccino varieties. Mission

Those early olive crops went into olive-oil production but, in the early 1900s, the industry shifted, as canning technology resulted in higher returns for table olives than for oil. Today, 90 percent of 's olive production is for canned olives, with only 10 percent crushed for oil. This is just the opposite of California , the world's leading olive producer, which grows 90 percent of its olive crop for oil and only 10 percent for cured olive products. Spain
