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 bracteosum Ribes bracteosum, the stink currant, is a species of currant native to western coastal North America from southeastern Alaska to Mendocino County in California.

The flowers are produced in spring after the leaves emerge, on racemes 15–30 cm (6-12 inches) long containing 20-40 flowers; each flower is 5–10 mm (2-4 inches) in diameter, with five white or greenish-tinged petals.
