Overview & Description

Josta Currant (Ribes x nidigrolaria) is a hardy, deciduous fruiting shrub that is a complex hybrid between black currant (Ribes nigrum), gooseberry (Ribes grossularia), and American black currant (Ribes divaricatum). Bred in Germany in the 1970s, it combines the best traits of its parents: the high yields and disease resistance of currants with the larger size and unique flavour of gooseberries. In spring, it produces inconspicuous clusters of pale yellow to greenish flowers that are self-fertile and attractive to pollinators. Its large, lobed, dark green foliage is similar to gooseberry but lacks thorns, making harvesting easier. The fruit is jet-black, round to oval, significantly larger than a standard currant, with smooth skin and a unique sweet-tart flavour—often described as a cross between black currant, gooseberry, and grape.

Growth & Size

This variety exhibits an upright, bushy, multi-stemmed growth habit. It is a fast-growing shrub, typically reaching a mature size of about 5 – 6.5 feet in height with a similar spread.

Additional Notes

It blooms in mid-spring, with fruit ripening in mid-to-late summer. Hardy to Zone 3, it is self-fertile, tolerates partial shade, and prefers moist, well-drained, slightly acidic soil. Drought tolerant once established. The berries are excellent for fresh eating, jams, jellies, pies, juices, and wines. Disease resistant, including immunity to white pine blister rust. An outstanding choice for northern gardeners seeking a unique, productive, and low-maintenance fruit shrub.
