The Inland Empire Feature

In 1873 a woman named Eliza Tibbets changed the course of California history when she planted two Brazilian navel-orange trees in her Riverside garden.

The trees (which were called Washington Navels in honor of America's first president) flourished in the area's warm climate and rich soil—and before long, Tibbett's garden was producing the sweetest seedless oranges anyone had ever tasted. After winning awards at several major exhibitions, Tibbets realized she could make a profit from her trees. She sold buds to the increasing droves of citrus farmers flocking to the Inland Empire, and by 1882, almost 250,000 citrus trees had been planted in Riverside alone. California's citrus industry had been born.

Today, Riverside still celebrates its citrus-growing heritage. The downtown Marketplace district contains several restored packing houses, and the Riverside Metropolitan Museum is home to a permanent exhibit of historic tools and machinery once used in the industry. The University of California at Riverside still remains at the forefront of citrus research; its Citrus Variety Collection includes specimens of 1,000 different fruit trees from around the world.
