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
Ribes cereum to form a corolla-like structure. Inside there are minute white or pinkish petals, five stamens, and a two protruding green styles. The fruit is a rather tasteless red berry up to a centimeter (0.4 inch) wide, with a characteristically long, dried flower remnant at the end. The Zuni people use the berries of the "pedicellare" variety as food, and eat the leaves with uncooked mutton fat or deer fat. Ribes cereum Ribes cereum is a species of currant known by the common names wax currant and squaw currant ("R. c." var. "pedicellare" is known as whisky currant). It is native
