Charles Rudolph Boysen (July 14, 1895 – November 25, 1950) was a California horticulturist who created the boysenberry, a hybrid between several varieties of blackberries, raspberries, and loganberries.
When Boysen first moved to Orange County, he brought berry vines with him which he planted on his in-law’s farm in Anaheim.
Unable to make his new berry a commercial success, Boysen abandoned his crop after breaking his back in an accident.
[3] Years later, a fellow grower named Walter Knott heard about the berry and tracked down Boysen.
It features playgrounds, baseball diamonds, a large lawn, and a stucco-coated Grumman F9F-6P Cougar as a children's climbing toy.
