Flowering currant
Ribes sanguineum · also: Red-flowering currant
Flowering currant is a thornless shrub from western North America that is hung with clusters of pink to red flowers in April, together with its young leaves. At that time it is an important source of nectar for queen bumblebees and bees. It grows 1.5–2.5 m tall, grows quickly and is easy in sun and partial shade. The leaves have a pungent, spicy smell. In summer they are followed by small bluish-black berries, edible but insipid.
Caution: Like other currants, it is an alternate host of white pine blister rust, a fungus that can kill Weymouth pines and other five-needled pines. Do not plant it close to such pines.

Identify
Flowering currant: how do you recognise it?
- Habit
- Upright, thornless shrub of 1.5–2.5 m.
- Leaf
- Alternate, 4–10 cm, round with 3–5 lobes, irregularly toothed, somewhat wrinkled and felted underneath; pungent and spicy when crushed.
- Bark
- Brown twigs without prickles.
- Flower
- Hanging to spreading clusters of pink, red or white flowers in April, together with the leaves.
- Fruit
- Bluish-black berries with a waxy bloom; edible, but insipid.
- Difference from blackcurrant
- Blackcurrant has greenish flowers and large, black, strongly scented berries.
Flowering: March–May · Pruning: April–May

Looks like it, but isn’t
- Blackcurrant Ribes nigrum: greenish flowers and large, black, strongly scented berries. Difference from blackcurrant
In your garden
Why grow it?
- One of the first shrubs to flower: clusters of pink to red flowers in April.
- Early nectar for queen bumblebees and bees.
- Easy and fast-growing, in sun or partial shade, on almost any soil.
- Thornless: also good in an informal flowering hedge.
Flowering currant: where does it grow best?
- Sun or partial shade; it flowers best in sun.
- Ordinary garden soil, acid or chalky; neither waterlogged nor bone dry.
- Allow 2 m width.
- Not close to Weymouth pines or other five-needled pines (see caution).
- Light
- Sun or partial shade
- Legal basis
- Any garden soil
- Moisture
- Normal
- Size
- 2 m tall, 2 m wide
- Hardiness
- Throughout Belgium, no protection needed
Goes well with
- Forsythia: Yellow next to pink in the same weeks: a classic spring pairing.
- Snowy mespilus: White blossom in April and later berries for the birds.
- Oregon grape: Yellow flower clusters in spring and evergreen leaves, for the same partial shade.
Good and bad companions
Goes well with
- Suits the woodland edge or the light shade of: ginkgo, box elder, ash, honey locust, field maple, silver maple
Best kept away from
- Blister rust alternates between currants and this pine: weymouth pine
Maintenance
Flowering currant: when and how to plant it?
- Plant from November to March, bare-root, root-balled or from a pot.
- In an informal hedge: one plant per metre.
- Plant at the same depth as before, firm the soil and water generously.
- After planting, shorten the branches by a third for a bushier shrub.
Care
- Watering
- In dry spells in the first year; after that only in long dry summers.
- Feeding
- A little compost in spring is enough.
- Mulch
- A layer of leaves or wood chips keeps the shallow roots cool and moist.
- Renewal
- Remove a few old branches every year after flowering: this keeps it free-flowering.
Tip: Plant it where you can see it from the house in April. For deep red, choose ‘King Edward VII’ or ‘Pulborough Scarlet’; ‘White Icicle’ flowers white.
Flowering currant: when to prune it?
Pruning months: April–May.
When: After flowering (April–May).
How:
- Every year, cut a few of the oldest branches off at the base; this keeps it young and free-flowering.
- Shorten overlong branches that have flowered back to a strong side branch.
- Rejuvenate an old, bare shrub over two or three years, removing a third of the oldest branches each time.
Caution: Do not prune in winter or before flowering: you would cut off the flower buds. April–May falls in the nesting season: check for nesting birds first.
Propagation
- Hardwood cuttings
- In winter (November–February), push 20–25 cm lengths of twig two-thirds into the ground in a sheltered spot; most root readily.
- Softwood cuttings
- Soft cuttings taken in June also root easily under glass or plastic.
Flowering currant: how does it get through the winter?
Hardy throughout Belgium: no protection needed.
- Fully hardy.
- In winter it is bare; the flower buds are already waiting on the twigs.
Diseases and pests
- White pine blister rust: Small orange to brown rust spots under the leaves in late summer. Harmless to the currant, but the fungus can attack Weymouth pines nearby.
- Coral spot: Small pink to orange pustules on dead branches. Cut those branches out into healthy wood and dispose of them.
- Aphids: Aphids on the young shoots in spring. Let ladybirds and tits do the work, or hose them off with water.
- Few flowers: An old shrub that is never pruned flowers less. Rejuvenate it by removing old branches every year.
Through the year
- January: Take hardwood cuttings.
- March: First flowers; last month for planting bare-root shrubs.
- April: Full flower; prune after flowering, checking for nests first.
- May: Last pruning month.
- June: Take softwood cuttings.
- August: Bluish-black berries; watch for rust under the leaves.
- November: Plant.
Use
What can you use it for?
- Garden and landscape
- Easy, fast-growing spring-flowering shrub for sun and partial shade.
- For wildlife
- Important early source of nectar for queen bumblebees and bees.
Caution: Like other currants, an alternate host of white pine blister rust: do not plant it close to Weymouth pines.
You and this species
Did you know?
- Plant hunter David Douglas brought it from north-west America to England in the 1820s; it was said that this one shrub alone was worth the cost of his whole expedition.
- In its homeland it is pollinated by hummingbirds, which visit its early flowers in spring.
- The smell of the leaves reminds some people of blackcurrant, and others of a cat’s litter tray.
