Navel oranges have been known in Spain and Portugal for centuries. They made their way from there to Brazil, where, in Bahia, a seedless and easy-to-peel variety of great taste and color was discovered. It was probably a sport (mutant) from the Portuguese variety ‘Umbigo’, which is said to be described in the Histoire naturelle des orangers by Risso and Poiteau (you can get your own copy). I could not find it in that book, but I did enjoy Poiteau’s botanical drawings, like this one2:
From Bahia the tasty navel went to Australia in 1824 and to Florida3 in 1835, and from Australia to California. But the introduction that led to adoption of the name ‘Washington’ and to its commercialization in California and around the world occurred in 1870, when William O. Saunders of the USDA received twelve trees from Bahia (twigs in an earlier shipment had been dead on arrival). They were planted in a greenhouse in Washington D.C. and propagated for distribution4.
On 10 December 1873, Eliza Tibbets of Riverside, southern California, traveled by buckboard to Los Angeles to pick up two of these trees, delivered by stagecoach from San Francisco5. Their fruits won first price at a citrus fair in 1879, and the ‘Washington’ navel spread rapidly after that — there was a citrus gold rush going on after the recent completion of the transcontinental railroad, which allowed selling to markets back east. Oranges were commonly propagated by seed in California, but the seedless ‘Washington’ had to be grafted. The Tibbets sold cuttings at a dollar each, earning as much as $20,000 a year.
In 1903, one of the original trees was transplanted to a location in front of the Glenwood Hotel in central Riverside, with president Roosevelt shovelling some of the dirt.6
That must have been about here (the name of the hotel was changed to Mission Inn). Alas, the tree died after a couple of years. But it was there long enough to be used in marketing:
The other ‘parent tree’ was planted a couple of miles south of the Glennwood Inn, in Low Park. It is still there, see for yourself, about 145 years old, despite its dire state 50 years ago:
for some years past it has been declining in vigor, and in 1967 seemed unlikely to survive much longer.
The tree is a ‘California historical landmark’ and has this plaque in front of it:
which states that, as of 1920, this was the
most valuable fruit introduction yet made by the USDA.
Riverside does not boast only that tree, it also has the California Citrus State Historic Park. And after you visit that, drive east to the Coachella Valley to see the dates that were introduced a few decades later.7

- Like these, which were reintroduced to Morocco, the Washington navel was reintroduced to Brazil after they had been wiped out there. [↩]
