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 indecorum toothed lobes, and are hairy, glandular, and aromatic. The inflorescence is a loose raceme of 10 to 25 flowers. The flower is roughly tubular with the white or pink-tinged sepals spreading open to reveal smaller whitish petals inside. The fruit is a hairy, sticky purple berry under a centimeter wide. This "Ribes" species, "Ribes indecorum", is another that is cultivated as an ornamental plant by specialty plant nurseries. It is planted in drought-tolerant, native plant, and wildlife gardens and natural landscaping projects. Ribes indecorum Ribes indecorum is a species of currant known by the common names white-flowered currant and white
