Ribes x nidigrolaria
fruitJostaberry (Ribes x nidigrolaria) is a vigorous, thornless shrub, up to about 6 to 8 ft tall, that is a complex hybrid of black currant and gooseberry. It bears large, smooth, dark reddish-black berries with a flavor between its parents: the deep, musky richness of black currant softened by the refreshing tartness of gooseberry, good fresh or cooked. It is self-fertile, easy, and notably disease resistant, shrugging off the powdery mildew, leaf spot, gall mites, and white pine blister rust that trouble its parents. Note that as a member of the genus Ribes it is legally restricted in some states.

Grow jostaberry in full sun to partial shade in fertile, moist, well-drained soil. It is self-fertile, though a second plant can boost yields. It is more vigorous and larger than currants and needs less fussy pruning: in late winter thin out the oldest wood to keep the bush open and productive. It is cool-climate by nature and appreciates afternoon shade and steady moisture in warm regions. Although jostaberry itself resists white pine blister rust, it is still a Ribes, so check local rules: currants and gooseberries are legally restricted in several states (all Ribes are prohibited in North Carolina, with patchwork restrictions elsewhere).

Can blister leaves; rinse off and conserve ladybugs (jostaberry is fairly resistant)
Gooseberry sawfly
Larvae strip leaves; hand-pick and check undersides of leaves in spring
Larvae tunnel canes; cut out and destroy any wilting canes
Harvest jostaberries over a long season as they ripen: picked early and firm they are tart and gooseberry-like for cooking, and left to fully ripen to near-black they grow sweeter and richer for fresh eating. The first crop comes in the second year. The berries are excellent in jam, pie, and juice as well as fresh.
Jostaberries are rich in vitamin C and antioxidants, combining the deep flavor of black currant with the tartness of gooseberry. They are eaten fresh when fully ripe and used in jams, pies, and juice.
