All boysenberries in the world can trace their roots to Knott’s Berry Farm. In 1920, Walter and Cordelia Knott moved to Buena Park to farm 20 acres of land and sell the first boysenberry—their cross of a loganberry, red raspberry, and blackberry. The fruit is named after its originator, Rudolph Boysen.
Young ones growing up near the attraction understandably can’t picture it as anything besides a magnificent theme park that's home to thrill rides and the Peanuts gang. The farm, however, is the foundation of the park. And the annual Boysenberry Festival—this year from March 29 to April 28—provides the perfect opportunity to merge the delicious history of the farm with its family-friendly modern identity.
