Black Currant 'Josta'

Ribes nigrum 'Josta' | Rating: 0 votes | Print / Pdf

Ribes nigrum or Blackcurrant is widely grown both for commercial production and in domestic gardens. It's a shrub that will grow up to around 5ft in height. The leaves are lobed and serrated. Even when it is not in fruit, the plant will smell of blackcurrants. It has small white flowers and produces glossy black berries which are very tasty and a rich source of vitamin C. A mature bush can provide up to 11 pounds of berries. Prune your blackcurrant bush each year. Due to a lack of imported fruit during WWII, the UK government encouraged the growth of blackcurrants to help provide the population with a source of vitamin C. At this time, blackcurrants were grown and made into a syrup which was distributed to children free of charge. Blackcurrant flavouring remains popular in the UK to this day.
