The Parent Washington Navel Orange Tree is a tree grown by Eliza Tibbets in Riverside, California, in 1873. The Riverside County tree was designated a California Historic Landmark (No.20) on June 1, 1932, at the corner of Magnolia Street and Arlington Street, Riverside. The Bahia, Brazil, Washington navel orange was brought to the United States by the U.S. Department of Agriculture in 1870. The Department of Agriculture imported twelve trees; from these trees, some buds were grafted on to California sweet orange trees. The Washington Navel Orange is also called California Navel Orange.
