Description
Korsor black elderberry (Sambucus nigra) is a vigorous variety that produces large sweet fruits. It is a beautiful bush that grows quickly and is easy to cultivate. Ideally, it should be planted in autumn for a harvest in September.
The black elderberry produces small round berries at the end of summer, with a black-purple colour and a diameter of about 5 mm (0.25 in). Both the berries and the flowers are edible, but they must be cooked before consumption. Whether eaten alone or combined with other fruits, these berries are delicious in jams, jellies, or syrups. As for the flowers, they can be used in fritters or infusions.
'Korsor' is a vigorous variety of Austrian origin. The flowers, in the form of white corymbs, appear around the month of May and have a pleasant fragrance. They are followed by the formation of small violet-black berries arranged in downward-facing clusters. The harvest of this variety takes place around September. It will gradually increase during the first few years and become optimal from the fifth year onwards.
The black elderberry can be found in nature at the edge of woods, in hedges or thickets, and is sometimes confused with yew, whose berries are toxic. The black elderberry is a beautiful, fast-growing, self-fertilising bush that can reach a height of 3 to 5 m (10 to 16ft). Its therapeutic properties have been known since ancient times. In the garden, you can plant it in a flowerbed, as an informal hedge, or as a standalone plant. Its tender and pithy stems, dense foliage, fragrant flowers, and black berries attract numerous insects and birds, thus promoting biodiversity in the garden. The black elderberry is a very hardy small tree with opposite, finely dentate leaves that emit an unpleasant odour when crushed. Although deciduous, its leaves are among the first to appear in spring. Add these leaves to your compost to speed up decomposition or make a liquid fertiliser to combat mildew and aphids.

Planting and care
The black elderberry is ideally planted in autumn, or alternatively in spring. This bush thrives in all types of soil, preferably moist. Choose a sunny or partially shaded location. Soak the root ball in water for a few moments before planting. Dig a wide and deep hole and add compost or potting soil. Place the root ball in the hole and cover with soil. The black elderberry is not particularly susceptible to diseases and pests, and does not require any specific care in this regard. Pruning is not necessary.

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.
