A deciduous shrub with early-maturing fruit, usually ripening at the end of July or early August, so it can be useful to extend the cropping season. It produces high-yielding, good quality fruits with a great flavour that are good for all culinary uses. As it is late flowering it is seldom damaged by frost. Blackcurrants are self-fertile and have clusters of insignificant yellow-green flowers in spring.

Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea

This genus produces blackcurrants

How to Grow

Cultivation

Blackcurrants prefer a sunny site with well-drained but moisture-retentive soil, but will cope in most other soil conditions and tolerate light shade. Mulch annually with well-rotted manure or compost and apply a general purpose fertiliser in spring. Please see our blackcurrant cultivation page for more growing tips.

Propagation

Propagate by hardwood cuttings

Suggested planting locations and garden types

  • Cottage and informal garden
  • Wildlife gardens
  • Edible fruit

Pruning

Prune in winter. Blackcurrants fruit best on younger wood so aim to remove up to one quarter of the oldest stems at ground level to encourage new growth from the base.

Pests

May be susceptible to gall mites, gall midge and aphids

Diseases

May be susceptible to a leaf spot, powdery mildews, coral spot and sometimes honey fungus
