Origin Story

Originating from a spontaneous mutation discovered in Bahia, Brazil, in the early 19th century, the Washington Navel Orange was introduced to the United States in 1870. The USDA distributed cuttings to California, where Eliza Tibbets planted them in Riverside in 1873, sparking the growth of California's citrus industry. This variety is a clone propagated vegetatively from that original mutation.

Classification

Classified botanically as Citrus sinensis, the Washington Navel Orange belongs to the sweet orange group. It is a cultivar distinguished by its seedless fruit and unique secondary fruit formation, a bud sport mutation within the species. It sits within the broader family Rutaceae and genus Citrus, alongside other commercial oranges like Valencia and blood oranges.

Appearance or Form

The fruit is medium to large, typically 6 to 8 centimeters in diameter, with a round shape and bright orange rind that is thick yet easy to peel. Its hallmark is the navel—a small, button-like secondary fruit at the blossom end. Inside, the flesh is deep orange, tender, juicy, and completely seedless. The tree itself is medium to large, vigorous, and upright, adorned with dense, dark green foliage.

Behavior or Usage

Primarily enjoyed fresh, Washington Navel Oranges are favored for their sweet, rich flavor and ease of peeling. They are rarely used for juicing due to the juice’s tendency toward bitterness and quick spoilage. This variety thrives in retail markets across North America, Europe, and Australia, commonly eaten out of hand or incorporated into salads and desserts.
