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 colandina this species, where it is replaced by "R. viscosum". Ribes colandina Ribes colandina is a species of currant found only in Perú. "Ribes colandina" differs from "Ribes andicola" in uniformly dark red flowers (petals red, not orange-yellow as in "R. andicola"), black instead of yellow fruits and wider, more deeply lobed leaves. "Ribes colandina" is a dioecious shrub approximately tall; densely to moderately tomentose from simple, curly trichomes long and with scattered subsessile glands, especially on young shoots and the abaxial leaf surface. Its petiole is long, wide; its stipules well differentiated, united with the petiole for . Inflorescences are
