Ribes nigrum LOWBERRY® ‘Little Black Sugar’ brings full blackcurrant flavour to a dense bush that fits comfortably on a terrace or in a small bed. Early black berries are sweet, juicy and milder in their characteristic aroma, making them pleasant to eat straight from the string. With healthy foliage, good branching and a final height of about one metre, it delivers far more fruiting-shrub experience than its compact scale suggests.
Place it near a path or seating area, as ripe berries are ideal for frequent small pickings once they turn deep black.
Its value lies in the rare union of truly compact growth and sweet black fruit for fresh eating.
Naturally dense branching keeps the bush around 80–100cm without losing the characteristic Ribes form.
High sweetness softens the strong resinous blackcurrant note and makes the fruit friendly for eating straight from the bush.
Short strings ripen from mid-June, opening the season before many taller blackcurrants.
Why you will love it: It combines the feel of a full fruiting shrub with a size that lets you see and pick every berry easily.
Give it morning sun and protection from the fiercest afternoon light. Allow 80–100cm in height and 60–80cm in spread, leaving a clear 20cm circle around the crown.
Use low foliage and flowers that highlight the black berries without covering the compact bush.
Sun to partial shade; avoid fierce reflected heat.
Deep watering when the surface dries, especially while berries fill.
Very good winter hardiness; compact roots in a container need protection from extreme frost.
Wash fully ripe fruit before eating.
Plant in fertile, humus-rich soil that holds even moisture without waterlogging. An organic mulch over the outer root zone keeps the soil cool.
Water deeply when the surface dries, with particular consistency from flowering until the berries fill. Avoid both prolonged drought and permanently saturated soil.
Keep 6–8 short basal stems with light in the centre. Support is rarely needed beyond a low ring if fruiting tips bow.
In early spring add mature compost and a balanced fruit-shrub feed according to its label. Stop nitrogen-rich applications early in summer.
In regions with very hot summers choose morning sun and afternoon shade. A lasting mulch and deep watering protect the shallow roots.
Remove a few dark old stems each year, clear fallen leaves from the dense centre and avoid wetting foliage in the evening.
It is self-fertile and crops alone. A second blackcurrant with similar flowering time can improve filling of the strings.
Harvest begins early, from mid-June, and continues into early July.
Pick the short string when every berry is black, soft and sweet, or take the ripest berries one by one.
The low crown is easily covered with a small netted dome. Lift it daily for picking and inspection.
After planting: maintain even moisture and let the bush fill with short strong stems before beginning annual renewal.
Late February to early March, before bud break
‘Little Black Sugar’ is naturally compact but needs light in the centre to keep berries sweet. Remove a few of the darkest stems each year and never clip the outer surface into a ball.
Action: Remove only broken, very thin or horizontal stems lying over the soil.
Retain: Keep 5–6 strong short stems to build a full bush.
Action: Thin one crossing branch from the centre and remove very low laterals. Leave healthy tips at their natural length.
Retain: Keep 6–8 well-lit stems and short strings on younger wood.
Action: Cut 2–3 of the thickest darkest stems at ground level and choose the same number of new replacements.
Retain: Retain the low outline while creating clear windows of light between stems.
Use sharp, clean tools suited to the diameter of the wood.
Remove one exhausted stem only if it shades new growth. Leave the remaining foliage until natural leaf fall.
Do not do this: Do not shorten every tip to keep it small; it is already genetically compact and uniform clipping crowds the crown unnecessarily.
Short basal stems branch early and quickly fill a large container.
Short strings appear among lobed leaves and darken before many tall cultivars.
Annual removal of a little old wood keeps the crown young without increasing final height.
Mature ‘Little Black Sugar’ is low, well branched and filled with short fruit strings among dense lobed foliage.
Genetically reduced growth combines with normal-sized leaves and berries; it is not a bonsai.
What to expect after planting: Short basal stems branch early and quickly fill a large container.
‘Little Black Sugar’ emerged from Lubera’s long-running blackcurrant programme in Switzerland. For about 25 years breeders combined Swedish, Russian, Lithuanian and Ukrainian lines, seeking sweeter fruit, larger berries and cleaner foliage.
Within this material an unusually short, heavily branched bush was selected. In trials it remained around one metre tall, showed good mildew tolerance and ripened early berries in which sweetness dominated the strong blackcurrant aroma.
The selection joined the LOWBERRY® range during the 2010s and was named ‘Little Black Sugar’ to describe the bush size and fruit character. Its stable compact habit opened blackcurrant growing to terraces and small beds.
A higher ratio of soluble sugars to acids does not remove cassis volatiles; it changes how the palate perceives them, making the flavour milder.
Reduced vertical extension is accompanied by more short laterals, allowing the bush to retain a large leaf area and many fruiting sites in a low volume.
Six practical answers for choosing, growing, harvesting and pruning this exact cultivar.
No. It is self-fertile, while a second blackcurrant can improve filling of the strings.
Approximately 80–100cm high and 60–80cm wide, with naturally dense branching.
Yes. Use a large deep container, cool compost and a low ring only if the tips bow.
From mid-June into early July, when berries are fully black, soft and sweet.
No. Sweetness is dominant and the characteristic aroma is milder than in many traditional blackcurrants.
In late winter, removing 2–3 of the darkest old stems at ground level.
