Redcurrant
Ribes rubrum
Botanical family: Grossulariaceae
Ribes rubrum (redcurrant, red or white) and Ribes nigrum (blackcurrant, cassis in French) are two different species. Wild in the woods of north-eastern France, both are widely grown. Sources: Tela Botanica, “Ribes rubrum L.” and “Ribes nigrum L.” (Coste's flora); Plants For A Future, “Ribes rubrum” and “Ribes nigrum”.
Partial shade
Rich, drained
Regular: likes soil that stays moist, especially in summer
Very hardy (~-25 to -30 °C)
Overwinters in your zone
Self-fertile
One plant is enough for a crop
Role in permaculture
An intermediate shrub layer (1-1.5 m), excellent in the understorey of fruit trees or in the cool partial shade of the vegetable garden. A perennial for 15-20 years. Produces berries in easy-to-pick clusters. Gentle pruning in winter (old wood over 3 years). Keep away from five-needle pines (such as Weymouth pine, Pinus strobus): Ribes are the alternate host of white pine blister rust (Cronartium ribicola), a proximity even regulated in some regions (USDA Forest Service; PNW Pest Management Handbooks).
Good companions
Harbour beneficial insects (insectary plant)
Aromatic: scent said to confuse pests
Traditional companion planting (benefit not demonstrated)
Poor companions
Alternate hosts of a disease (e.g. rust)
Insects attracted or useful

Nutritional & medicinal properties
For educational purposes. Not a substitute for medical advice. Effects depend on the form, the dose and personal context.
Precautions & contraindications
A safe fruit, with no known toxicity. Very tart, especially picked before full ripeness: a large quantity can cause digestive discomfort in sensitive people.
Family behaviour: Grossulariaceae
In general, Grossulariaceae bring together the small soft-fruit shrubs of the genus Ribes (redcurrant, blackcurrant, gooseberry). Shallow-rooted, they like part shade and a cool, well-mulched soil, which makes them good companions under taller fruit trees.
