A boysenberry is a cross between a European Raspberry (Rubus idaeus), a Common Blackberry (Rubus fruticosus), and a Loganberry (Rubus × loganobaccus). It is a large (8.0 g/0.28 oz) aggregate fruit, with large seeds and a deep maroon color, which changes to the typical boysenberry color when the fruit is cooked and made into jam and pies. In the late 1920s, George M. Darrow of the USDA began tracking down reports of a large, reddish-purple berry that had been grown on the northern California farm of a man named Rudolph Boysen.
