Description
The Carex acuta, also known as the Sharp-Edged Sedge, a plant related to grasses, is found along the water's edge in our marshes, throughout France, and especially in the central and northeastern regions. This medium to large-sized perennial forms a clump of evergreen, very fine, bluish-green leaves and produces beautiful cylindrical spikes of dark brown flowers, between May and August. This carex is planted on the edge of a water point for its qualities as a bank stabilising plant. It can also be used for its purifying qualities in a phytoremediation pond. It requires no maintenance.
The Carex acuta belongs to the Cyperaceae family. Native to Eurasia, it is found almost everywhere in the world. This rhizomatous plant, similar in appearance to grasses, with running rhizomes, forms an upright and arching clump, reaching a height of 50 to 80 cm and a diameter of about 40 cm, spreading over time to form large colonies in moist or waterlogged soils. This species grows at a depth ranging from 0 to -5 cm of water. Its leaves, evergreen in winter, sheath-like at the base, are long, slender (4 to 8 mm wide), linear, with tapered edges, slightly trailing. They have a bluish-green colour. The older leaves dry out in winter to make way for new leaves in spring. In spring, in April-May depending on the climate, floral stems appear bearing male or female spikes. The male spikes, thick, cylindrical-elliptical, dark brown, barely emerge from the foliage and are quite decorative. As with all Carex species, it is monoecious, producing separate male and female flowers on the same individual.
The Carex acuta can be planted in any type of wet area, in full sun or partial shade. Useful for maintaining banks or for its purifying qualities, it can also be planted for its ornamental value on the edge of a pond. In the company of other bank plants, equally decorative, such as Acorus, Cirsium rivulare or purple plume thistle, Butomus umbellatus or flowering rush, Alisma parviflora, or even Caltha palustris.

Planting and care
The Carex acuta is an easy-to-grow plant in full sun, in any moist garden soil, even clayey and heavy soil. It is capable of covering areas where it thrives. Water abundantly at planting, which should be done outside of frost periods. Avoid excessive fertiliser application. Remove damaged foliage during growth, but never prune the clump completely in late winter. If you want to prevent self-seeding, trim the faded flowers.
In phyto-purification, it is planted with a density of 8 plants per m2.

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.
