The exact origins of the boysenberry are unclear, but the most definite records trace the plant as it is known today back to grower
Rudolph Boysen, who obtained the dewberry–loganberry parent from the farm of John Lubben. He began selling the large berries at his farm stand in 1932 and soon noticed that people kept returning for more. When asked what they were called, Knott said, "Boysenberries", after their originator. His family's small restaurant and pie business eventually grew into
Knott's Berry Farm.
Cultivars Since 2007, a hybrid variety called the "Newberry" or "Ruby Boysen", was developed to overcome cultivation challenges that led to the decline in boysenberry popularity, and was marketed through farm markets and retailers in California. The 'Nectar' cultivar of boysenberry should not be confused with the nectarberry,
Rubus arcticus, a plant native to arctic swamps. == References ==
