Description
The Black Jewel Raspberry Bush is a vigorous and hardy variety, with the particularity of producing fairly round black raspberries, rich in antioxidants. Their taste is somewhere between raspberry and blackberry. Originating from the United States, this non-remontant (summer fruiting) variety does not sucker much and offers good yields. Planting from October to March, for a harvest around the month of July.
To fully enjoy their flavour, raspberries should be consumed quickly after picking, as they do not keep well. Whether they are red, yellow, or black, they can be consumed in the same way. If you have an abundant harvest, consider making coulis, sorbets, tarts, or jams. You can also freeze them. Production reaches its normal level in the third year after planting. One plant can produce fruit for around 10 years. There are two types of raspberry varieties: remontant, producing from June to October, and non-remontant, with abundant harvests occurring around June - July.
The Black Jewel Raspberry is a deciduous shrub with prickly stems, forming a bush about 1.30m (4ft) tall. The stems or canes are biennial, each having the particularity of dying after fruiting. The Raspberry Bush has leaves that are green on the top, white-green and downy on the underside. The flowering is very honey-bearing. The white flowers are small (1 to 2 cm (0 to 1in) in diameter), grouped in small clusters of 10 to 12, and appear in April-May. The fruits are formed by small agglomerated drupes, easy to detach at ripeness, and their colour varies depending on the variety: red, yellow, or black for the Black Jewel variety.
The Raspberry Bush belongs to the Rosaceae family, like strawberries, blackberries, and wild roses. The wild raspberry is native to Europe and temperate Asia, where it grows in cool climates alongside elderberry, beech, or mountain ash, especially in mountainous undergrowth, but also in the plains.

Planting and care
The Raspberry prefers humus-rich soils that retain moisture, even in summer, without too much limestone. It appreciates partially shaded but bright exposures. In the northern regions of Europe it will tolerate full sun, while in the south, it prefers partial shade. Plant it from October to March in ordinary soil enriched with compost and well-rotted manure.
Space the plants every 80cm (32in) in rows that are 1.50m (5ft) apart. During planting, the collar should be level with the ground. It is recommended to train them with wire stretched between stakes or on a trellis.
Water regularly to promote root establishment in the first year of planting. During periods of high heat or prolonged drought, provide additional water. Weed the surface especially at the beginning of planting and apply mulch to retain moisture in the summer.
The Raspberry can be susceptible to different diseases if the growing conditions are not optimal (raspberry anthracnose, raspberry rust, powdery mildew, grey rot during rainy periods, or Botrytis). The damage observed in cultivation is due to poor weather conditions, especially during cold springs that allow micro-fungi present in the soil to infest the vegetation. To protect the plants, it is recommended to feed the raspberries with organic fertilisers that promote the multiplication of anaerobic bacteria in the soil, which strengthens the soil's ability to stimulate the plant's immune system. Raspberries can also be attacked by certain parasites such as raspberry worms, the larvae of a small beetle that lodges in the fruits without causing significant damage.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
