My husband and I have been doing grass cutting jobs. Today he trimmed what he thought was a black berry bush but the residents who do not own the tree as it is in the neighbors yard (but was overflowing) say they think it is boysenberries because it is high up off the ground. Does anyone know the difference between a boysenberry and a black berry. From experience (today for the first time) I can honestly say both are good with pancakes.
