Boysenberry

A boysenberry is a hybrid berry, a cross between a European raspberry (Rubus idaeus), an American dewberry (Rubus aboriginum), and a blackberry (Rubus fruticosus). The fruit is typically dark purple to black in color, larger than a raspberry, and has a tart, sweet flavor. Boysenberries are often used in jams, syrups, and desserts. The berry is named after its creator, Rudolph Boysen, a Swedish-American farmer. In Hebrew, boysenberry is known as תות בואזן (tut boazen). In French, it is called mûre de Boysen, and in German, it is referred to as Boysenbeere. The cultivation of boysenberries is most prominent in the United States, particularly in California, and in New Zealand, where they were further developed and popularized by Walter Knott of Knott's Berry Farm.
