Description
Juncus inflexus 'Blue Arrows' is an interesting variety of rush with a slender habit and dense vegetation with soft shades of blue-grey, making it even more decorative than the classic gardeners' rush. It is a perennial for ponds, banks, and wetlands that also adapts to ordinary, fairly dry soils in summer. It forms tall clumps of stiff stems, with a refined sculptural quality that remains decorative even in winter. Ideal at the edge of water bodies where it adds verticality to aquatic scenes, it also makes a very beautiful plant for contemporary patios and balconies.
Juncus inflexus is a rhizomatous, stoloniferous perennial plant with persistent stems and semi-evergreen foliage, with a distinctly bristly habit. It belongs to the Juncaceae family. Its origin is found throughout Europe, Turkey, the Caucasus, Iran, and Central Asia. The 'Blue Arrows' rush will reach about 90cm (35in) in height, and will spread through its rhizomes for about 45cm (18in). This variety remains dense at the base. Its stems are bluish-green to blue-grey. The leaves are reduced to basal sheaths of shiny blackish purple. Flowering occurs from June to August. The spike-like flowers are brown in colour.
In nature, rushes grow at the edge of wet ditches in stagnant and shallow water. Juncus inflexus 'Blue Arrows' should be planted at a depth of 20cm (8in), with its stump submerged up to 10cm (4in). Tidy it in autumn by cutting back the foliage to 10cm (4in).
The 'Blue Arrows' rush can be used in containers in compositions of annual plants, in flower beds of perennials, or at the edge of stagnant water as an evaporative plant. In containers, plant it in the centre, surrounded by smaller plants and creeping plants that will spill over the sides of the pot. It fits perfectly in a minimalist or contemporary decor and works wonders near a pool. This plant thrives particularly well in marshy to wet gardens, including clayey and limestone soils, but it is robust enough to survive drier periods. It can also be planted in submerged containers in ponds. This rush is suitable for coastal use.
This plant was used before candles or torches to provide light. It was dipped in vegetable or animal fat and allowed to harden.

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.
