Description
Carex nigra is an evergreen rhizomatous perennial that grows spontaneously in wet and marshy areas in Europe, western Asia, and northwestern Africa, as well as northeastern North America. It has quite a large erect tuft, 80cm (32in) tall and 60cm (24in) wide. It bears stiff, rough, thin leaves measuring 1 to 3mm (1in), with a glaucous green colour. It bears an upright flowering of black spikes that punctuate the rigid tips of its foliage. This sedge species is specially adapted to the edges of ponds, naturally serving as a bank stabiliser. It is very hardy and easy to grow in all types of ordinary soils, even clayey, in moist to wet conditions. Place in full sun or partial shade.
Carex nigra, also known as black sedge, belongs to the Cyperaceae family. It is widely distributed from northeastern North America to western Asia. It is a perennial with foliage that closely resembles that of grasses and is often grouped with them. It is common in wetland environments such as marshes, alkaline or acidic fens, and wet meadows.
With rapid growth, it is perfect in natural gardens that are quite moist. Its rhizomes make it easy to retain soil and help stabilise banks and sloping ground. Plant it with groups of other wet bank perennials to bring lightness and movement. It is also a good plant for containers, to be placed on balconies or patios. In a small garden with water features, its inflorescences and light foliage will stand out beautifully against white walls. Planted en masse along a path or alleyway, it will emphasise and soften the layout in a contemporary or rural garden.
With 1000 species of sedges growing worldwide, you are sure to find one that suits your garden. They can be found in all environments where plants grow. Some adapt very easily to many situations and any garden soil, while others must be cultivated in their specific environment. Make your choice!

Planting and care
Prepare a planting hole that is 20x20x20cm (8x8x8in) in size. If your soil is heavy, mix some compost with the crumbled soil, partially fill the hole, and place your plant so that the top of the root ball is covered with 3cm (1in) of soil. Firmly press down and water generously to eliminate air pockets. In dry weather, you will need to water regularly for a few weeks to facilitate the establishment of your young plant.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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.
