Description
Carex Comans 'Bronze Form' is a New Zealand Sedge prized for its bronze-coloured foliage with metallic reflections. This grass forms a dense, fountain-shaped tuft composed of numerous long and slender flexible leaves, in which the wind and light play. Its vegetation takes on beautiful shades of orange in autumn and persists throughout winter. Perfect in a contemporary setting, and in a naturalistic-style bed. Its sculptural aspect also adds character to a patio or balcony.
Carex comans is a grass native to New Zealand, particularly the Stewart Islands. It grows in clear understories and forest edges, in well-drained soils, from coastal areas to subalpine meadows. Like all carex, it belongs to the Cyperaceae family.
As its name suggests, 'Bronze Form' stands out from the typical species with its foliage colour, as well as its broader and more flexible habit. The leaves are very fine, linear, strongly arched, and curled at their tips. They form a fountain-like shape measuring 40cm (16in) in height and 45 to 50cm (18 to 20in) in diameter. In spring, their colour is a light brown in the centre, becoming more silvery at the tips. In summer, the overall colour is a lovely dark bronze tone, shining with silver reflections. In autumn, the vegetation takes on orange to brown hues. The flowers appear in June and July and are a reddish-brown colour, but they have no significant ornamental value. Similar to Carex buchananii, Carex comans is easier to cultivate in well-drained clay soil. It thrives when planted in full sun or partial shade, in ordinary, moist soil. It tolerates summer drought quite well.
Plant Carex comans 'Bronze Form' along a pathway, in a raised bed, in a rockery, or on top of a wall, allowing its foliage to cascade naturally. For example, pair it with the grey or blue-grey foliage of Stachys byzantina 'Big Ears' or silvery santolina. The acid green flowers of euphorbias (Euphorbia myrsinites), the small purple pompoms of ornamental garlic, and the mauve aster 'Silberblaukissen' will enhance the brilliance of its warm-coloured foliage. Resourceful gardeners can use this plant to create unique decorations, such as placing several pots of Carex comans at different levels on a wooden structure. At the base of this structure, plant some annuals like marigolds, red salvias, purple morning glories, and blue lobelia.

Planting and care
It thrives in the sun, but also in partial shade. Preferring slightly moist soils in summer, it withstands summer drought once well established. However, very wet and heavy soils are detrimental to it in winter. 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).
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.
