Blackcurrant Jostaberry

The Josta Gooseberry (Ribes hybrid) or Jostaberry is a variety that produces berries resembling large blackcurrants, with a skin that is black and a texture similar to that of gooseberries. The name "Josta" comes from the contraction of "cass-is" and "gros-eille" (French for blackcurrant and gooseberry). The fruits have a tangy flavour and a lighter fragrance than blackcurrants, making them perfect for jams, sorbets, or pies. Ideally, they should be planted in autumn or spring with regular watering for a harvest in July.

The Josta Gooseberry belongs to the Grossulariaceae family and is the result of a cross-breeding between the blackcurrant and a close relative of the gooseberry. It is a thornless bush with a spreading and bushy habit, reaching a height of 2m (7ft) and a width of 1m (3ft). It is very hardy, withstanding temperatures as low as -18°C (-0.4°F). Its rounded lobed leaves are deciduous and slightly fragrant. Flowering occurs in spring, around April - May, with small dark red flowers. This is followed by the formation of short clusters, with berries resembling large blackcurrants, with a dark and smooth skin and a texture similar to that of gooseberries. The harvest is usually abundant and staggered depending on the ripeness of the fruits. Josta Gooseberries, with their tangy flavour and lighter fragrance than blackcurrants, are perfect for jams, ice creams, sorbets, and pies. They can also be frozen.

The Josta Gooseberry is self-fertile and does not require another plant for pollination. However, it is recommended, when space allows, to alternate varieties and species to promote pollination and reduce the risk of diseases. In the garden, create a small edible hedge by mixing Josta Gooseberries, raspberries, and gooseberries, for example, or place the Josta Gooseberry within a flower bed.
