  Hybride Mûre/Framboise Boysenberry


• (Developed by Ralph Boysen, California, 1920) Derivation: Rubus ursinus. Vigorous, trailing canes. Flowers susceptible to damage by plague thrips. Fruits early December to mid-January. Purple-black, downy, long and plump berries up to 35mm long x 20mm diameter. Flavour is aromatic/acidic when ripe. Berries have a characteristic aroma that is a major identifier of the fruit. Both thorny and thornless forms exist. The thornless forms are periclinal chimeras (that is, only the epidermal layer of tissue is genetically thornless), and therefore suckers growing from damaged roots will be thorny. There appear to be several forms of Boysenberry in commerce; variations are seen in the ratio of fruit length:width, general vigour and productivity. The fruit are often confused with Youngberries (see below).
