Rafaela Tijerina first met la señora at a school in the town of Lost Hills, deep in the farm country of California’s Central Valley. They were both there for a school board meeting, and the superintendent had failed to show up. Tijerina, a 74-year-old former cotton picker and veteran school board member, apologized for the superintendent — he must have had another important meeting — and for the fact that her own voice was faint; she had cancer. “Oh no, you talk great,” the woman replied with a warm smile, before she began handing out copies of her book, Rubies in the Orchard: How to Uncover the Hidden Gems in Your Business. “To my friend with the sweet voice,” she wrote inside Tijerina’s copy.

It was only later that Tijerina realized the woman owned the almond groves where Tijerina’s husband worked as a pruner. Lynda Resnick and her husband, Stewart, also own a few other things: Teleflora, the nation’s largest flower delivery service; Fiji Water, the best-selling brand of premium bottled water; Pom Wonderful, the iconic pomegranate juice brand; Halos, the insanely popular brand of mandarin oranges formerly known as Cuties; and Wonderful Pistachios, with its “Get Crackin'” ad campaign. The Resnicks are the world’s biggest producers of pistachios and almonds, and they also hold vast groves of lemons, grapefruit, and navel oranges. All told, they claim to own America’s second-largest produce company, worth an estimated $4.2 billion.
