Heritage Reserve Navel Oranges, known for their exceptional flavor, are grown exclusively within a small sub-section of California's renowned Central Valley citrus-growing region — a narrow, 25-mile long area adjacent to the western foothills of Sequoia National Park. The orchards were planted between 1896 and 1960 to the original Washington variety and continue to be prolific. These oranges are naturally colored and no accelerated de-greening processes were used.
