Currants: redcurrant (Ribes rubrum) blackcurrant (Ribes nigrum) and gooseberry (Ribes uva crispa) originate from the western part of Europe. Deciduous shrubs, 1 to 1.5 meters high, palmately lobed leaves with five lobes. The plant has inconspicuous, yellow-green flowers. The berries (red, white or black) have a diameter of between 8 and 12 mm and hang in clusters of 3 to 10 berries. The length of the truss is 4 to 8 cm. An adult bush can yield 3 to 4 kilos of berries; harvest July, August and early September. Gooseberries are usually green and covered with fine hairs.

Damaged and subsequently dried out ripe berries: hail and heavy rain can cause this, especially after a period of drought followed by rain. The berries swell, making the skin thin and fragile.
