Description
Carex berggrenii is a miniature and evergreen sedge that forms a very low tuft of grass-like foliage beautifully coloured from bronze to copper brown throughout the seasons, with a slight metallic sheen. This small grass spreads very slowly, forming a small ground cover adorned with short brown spikes, and remains attractive throughout the year, even in winter. Hardy and undemanding, this lovely perennial plant will thrive in fresh rock gardens or bordering flower beds, in well-drained but moist soil, in full sun or partial shade.
Carex berggrenii is a rhizomatous perennial from the Cyperaceae family. It is native to New Zealand. This species grows in subalpine mountain areas. It thrives in cool and sunny locations in nature, and is highly resistant to frost (down to -18°C (-0.4°F)). It adapts to any well-drained soil without excessive limestone content. Its foliage consists of almost flat ribbon-like leaves, 3 to 6cm (1 to 2in) long and 1.2 to 3mm (1in) wide, with very distinct veins and a slightly glossy appearance. They emerge in a fern-green to olive-green colour and quickly turn bronze. They are clustered in a very dense tuft that will not exceed 5cm (2in) in height. It slowly expands to form a low cushion about 30cm (12in) wide. In cold weather, the leaves take on dark purple-red, burgundy red, or orange-red tones that are very decorative. The inconspicuous flowering occurs from March to July. It takes the form of short brown floral spikes 20cm (8in) long. This evergreen sedge retains its beautiful foliage in winter. Its colours will be more intense if it is exposed to full sun.
Carex berggrenii is an unusual border or rock garden plant, and is particularly pleasant in alpine troughs. It will thrive near a small pond or stream, as long as the soil is not constantly waterlogged. It can also be planted in groups of 5 to 10 specimens on the edge of cool woodlands or in the design of a living wall. Where it is happy, this sedge will form unique and highly decorative ground covers. It can be combined with other ground cover plants that appreciate similar conditions, such as small ferns (Polypodium), other small carex, saxifrages, and Ophiopogon. However, be sure to plant its neighbours at a respectable distance to avoid suffocating it.

Planting and care
Plant Carex berggrenii in full sun or partial shade, in any well-drained soil that remains moist in summer, without excess limestone. 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. It is cold-tolerant, but it does not tolerate heat or drought.

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.
