Boysenberry is a fruit that is a cross between a raspberry, a blackberry, and a loganberry. It is a large berry that is dark red in color and has a sweet-tart flavor.
The boysenberry was first grown in the early 1900s by Walter Knott, a farmer in California. He named the fruit after its creator, Rudolph Boysen.
Boysenberries are a good source of fiber, vitamins C and K, and manganese. They are also a good source of antioxidants.
Boysenberries can be eaten fresh, made into jam, or used in pies and other desserts.
