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 canthariforme a centimeter (0.2 inch) wide, coated in hairs. Ribes canthariforme Ribes canthariforme is a rare North American species of currant known by the common name Moreno currant. The plant is native to southern California, having been found in San Diego County, California (Laguna Mountains and surrounding slopes) and in western Riverside County (Elsinore and San Jacinto Mountains). It is a member of the local chaparral plant community. The most recent estimates indicate that there are about 70 individual plants remaining. Most of these occur on land within Cleveland National Forest, and since there are few serious threats the species is
