The Boysenberry was selected in the early 1920s in California, US. This is a hybrid between a wild raspberry and a lot of blackberry cultivars, including Loganberry.
Boysenberry plants have thornless canes, which are thin and trailing, so bushes need to be supported by a trellis system. New replacement stems can have thorns, and all root shoots will be thorny! It is early-summer harvesting variety. First flowers, which have white color, can be found on Boysen's plants at the middle of April. Ripe berries appear on floricanes in the second week of June. The berries are oblong or rounded (shape is very varied), juicy, large, dark purple or maroon in color when completely ripe. Taste of ripe berries is sweet, aroma is tangy floral and rich fruity. Under-ripe berries are slightly tart. Berries are soft, so Boysenberry are poorly adapted for fresh market, but it is still frequently grown in home gardens and is available at farmers’ markets when in season. Commercial Boysenberries are harvested when under-ripe with a reddish blush.
