Riverside's quietest historical figure: Eliza Tibbets and the two trees that started California's citrus economy.

In 1873, an abolitionist and suffragist planted two small orange trees outside her kitchen door. Every Washington Navel orange tree in California traces back to them. One is still standing in Riverside, in a tent, at Magnolia and Arlington.

In 1873, Eliza Lovell Tibbets received two small navel orange trees through the mail. She planted them outside her kitchen door in Riverside. They were among only a handful imported to California from Bahia, Brazil, by the U.S. Department of Agriculture.

Every Washington Navel orange tree in California traces its lineage back to those two trees. A century and a half of California's commercial citrus industry has its origin in Tibbets's backyard.

She's also one of the most under-celebrated historical figures in the city.

Who she actually was

Per Wikipedia's biography and the California Citrus State Historic Park, Tibbets was:

  • An abolitionist before the Civil War
  • A suffragist in the early American women's rights movement — "among the first wave of American feminism inspiring women such as Susan B. Anthony"
  • A spiritualist (the 19th-century religious movement that emphasized communication with the dead)
  • A horticulturist with no formal training but a sharp eye for what would grow in Riverside's soil
  • An early Riverside settler, building the intellectual life of the young colony alongside her husband Luther

In other words: a woman who, in the 1860s and 70s, was already openly progressive on the most important moral questions of her era — and who happened to also start a state's defining agricultural industry on the side.

What's there now

One of the original trees still stands at the corner of Magnolia and Arlington Avenues, encased since June 2019 in a 22-foot protective tent designed to shield it from citrus diseases that have devastated commercial groves elsewhere in California. It's California Historical Landmark #20. Maintenance is shared between UC Riverside and the Riverside Parks Department.

Most current Riverside residents have driven past it without knowing what it is.

Why we're noting it

Two reasons.

  1. Tibbets's name is on far less than she earned. There's a tribute marker at the tree. A grave at Evergreen Memorial Historic Cemetery. A 2011 biography by Patricia Ortlieb (Creating an Orange Utopia). But she's not on a major street, school, or building proportional to what she actually did.
  2. The tree is worth visiting. It's a quiet, weird, beautiful thing — a 152-year-old fruit tree in a glass tent, tended by a major research university and a city parks crew. If you've lived here for years and never stopped, stop.
