The Story of the Washington Navel Orange

How the Orange Came to California

The Washington Navel Orange has an interesting history. It started as a special kind of sweet orange found in a monastery in Brazil around 1820. This orange was unique because it had no seeds!

In 1870, the U.S. Department of Agriculture brought twelve of these special orange trees to the United States. They took small pieces, called buds, from these trees. These buds were then attached, or grafted, onto other California sweet orange trees.

Eliza Tibbets and the First Trees

In 1873, two of these young, greenhouse-grown trees were sent to Mrs. Eliza Tibbets in Riverside. She planted them, and one of them became the famous Parent Washington Navel Orange Tree. This tree helped make the Washington Navel Orange very popular across the country.

What Makes a Navel Orange Special?

The name "navel orange" comes from a small bump at the bottom of the fruit. It looks a bit like a human belly button! This special feature is actually a natural change, or mutation, that also makes the orange seedless.

Oranges cannot survive in very cold weather. Luckily, the warm climate of Southern California was perfect for growing these new navel oranges. This helped the California citrus industry grow very quickly.

Protecting a Historic Tree

Keeping the Tree Healthy

This historic tree needs special care to stay healthy. In April 2018, a white cloth was placed over the tree. This was to protect it from a serious plant sickness called citrus greening disease.

Later, in June 2019, the cloth was replaced with a large tent. This tent is 22 feet tall and 25 feet wide. It has a special insect screen to keep harmful bugs away from the tree.

Who Takes Care of the Tree?

Taking care of the Parent Washington Navel Orange Tree is a team effort. The UC Riverside and the City of Riverside Parks Department work together to maintain it.

In April 2019, some other orange and grapefruit trees from the 1940s were removed. They were not as historically important as the Parent Washington Navel Orange Tree.

Historical Marker

Honoring Eliza Tibbets

There is a special historical marker at the site of the tree. It was put there in 1920. This marker honors Mrs. Eliza Tibbets for her important work. It praises her for planting the first Washington Navel Orange trees in California.

The marker also explains that this orange, originally from Bahia, Brazil, was a very valuable fruit. It was one of the best new fruits brought to the United States by the Department of Agriculture.

Details from the Guidebook

The California Historical Landmarks Guidebook also talks about this marker. It confirms that the tree came from Brazil in 1870. It also mentions that twelve young trees were received. Buds from these trees were then grown on other sweet orange seedlings. In 1873, two of these special trees were sent to Mrs. Eliza Tibbets in Riverside.
