Native to northern Europe, redcurrants only really began to be cultivated in Britain with the introduction in the early 17th century of improved Dutch cultivars by plant hunter Tradescant the Elder* (Gareth Richards, ‘Keeping up with currant affairs,’ The Garden, July 2015, p.80.)
Interestingly red, white and pink currants (Ribes rubrum) are distinct from blackcurrants (Ribes nigrum), and although they have broadly similar growing requirements, their pruning is quite different.
For more info about redcurrants – including specifics about pruning – see The Garden, July 2015, pp 80-82.
* The sarcophagus of John Tradescant is located in the courtyard terrace of The Museum of Gardening, located in Lambeth, London.
** We have a redcurrant bush planted in front of the white rambling rose in the back patch beds (which lead towards the rhubarb patch). This has been left to grow wild and must be trimmed back and even possibly relocated into a more open, light location to promote fruiting.
