Carex nigra

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!
