Jostaberry Jostaberry The jostaberry ("Ribes" × "nidigrolaria") is a complex-cross fruit bush in the genus "Ribes", involving three original species, the black currant "R. nigrum", the North American coastal black gooseberry "R. divaricatum", and the European gooseberry "R. uva-crispa". It is similar to "Ribes × culverwellii", the Jochelbeere, which is descended from just two of these species, "R. nigrum" and "R. uva-crispa". The cultivated plants are tetraploid. They are descended from two separate first-generation crosses, both of which produced very few fruit. Fertile tetraploids were produced using colchicine. The name "Jostaberry" was created via combining the German words for blackcurrant and

The plant fruits purple gooseberries which are edible but are mainly seeds with little fruit, generally regarded as unpalatable. The plant's spines also make collecting fruit difficult. "Ribes menziesii" is cultivated as an ornamental plant for native plant and wildlife gardens, in areas of suitable climate, such as coastal California. It is valued for its attractive spring blooms. Ribes menziesii Ribes menziesii, the canyon gooseberry, is a species of currant found only in California and
