   Another Rubus character of particular interest is R. ursinus × idaeus, or boysenberry. This is a complex hybrid which came about as a cross between European raspberry (R. idaeus), common blackberry (R. fruticosus), and loganberry (Rubus × loganobaccus). The hyrbid was originally developed during the late 1920’s in California by a farmer named Rudolph Boysen.
