How to Identify

A deciduous shrub reaching 1.5 m (5 ft) in height. Hardy to UK zone 3. Hermaphrodite flowers pollinated by insects. Tolerates light sandy, medium loamy, and heavy clay soils with good drainage. Grows in mildly acid, neutral, or basic soil. Adapts to semi-shade or full sun and prefers consistently moist soil.

How to Grow

Easily grown in a moisture retentive but well-drained loamy soil of at least moderate quality. Plants are quite tolerant of shade though do not fruit so well in such a position. Hardy to about -20°c. This species could be useful in breeding programmes for blackcurrants. Plants can harbour a stage of 'white pine blister rust', so they should not be grown in the vicinity of pine trees. Plants in this genus are notably susceptible to honey fungus.

Propagation: Seed is best sown as soon as it is ripe in autumn in a cold frame. Stored seed requires 3 months of cold stratification at 0–5°c and should be sown as early in the year as possible. Under normal storage conditions seed can remain viable for 17 years or more. Prick out seedlings into individual pots when large enough to handle, grow on in a cold frame through their first winter, then plant out in late spring the following year. Cuttings of half-ripe wood, 10–15cm with a heel, taken July/August in a frame. Cuttings of mature wood of the current year's growth, preferably with a heel of the previous year's growth, taken November to February in a cold frame or sheltered bed outdoors.
