New Zealand Satin Flower
Beautiful young plant. A shoot was given to me by a friend, it has grown quickly and already forms a lovely clump in a sunny bed accompanied by a rhododendron and grasses. I recommend this plant, which is perfectly suited to the British climate as it grows without any issues despite wind and sea spray.

Description
The Libertia grandiflora, sometimes called New Zealand Satin Flower, is a beautiful rhizomatous perennial plant that is easy to grow and hardy down to -10°C (14°F). It is interesting for its clump-forming habit with stiff, linear foliage, as well as its delicate white flowers, carried on slender stems well above the foliage. They are followed by attractive black fruits when ripe. This plant is ideally planted at the edge of a water feature, in a sunny location. This species grows very well in pots, where it has a great impact.
Libertia grandiflora is a botanical species native to New Zealand belonging to the Iridaceae family. This upright clump-forming perennial will reach a height of 60 cm (24in) to 1.30 m (4ft), a width of 60 cm (24in), with a moderately fast growth rate. It forms a dense, slightly stiff, spreading clump. In late spring and early summer, thin stems appear between the foliage, carrying panicles of 3 to 6 flowers measuring 1.5 to 3 cm (1in) in diameter, with three white petals enclosed in a bract. The centre of the corolla is filled with yellow stamens. The plant produces an abundance of round, black seeds that germinate very easily. It develops evergreen foliage, composed of stiff, linear leaves, 30 to 60 cm (12 to 24in) long and 0.3 to 1.5 cm (0 to 1in) wide, which are a dark green colour.
Plant Libertia grandiflora in any moist but well-drained soil, which is preferably humus-rich. It requires a sunny position to flower. Truly attractive plant in many ways, both opulent and vertical, it is magnificent in water gardens, with a wild or even Asian-inspired look due to its clean shapes. It highlights both the layout of a pathway and the banks of a pond, or the surroundings of waterfalls and artificial streams. It pairs well with Sisyrinchium, Crocosmia crocosmiiflora Emily McKenzie, Liatris, or Calamagrostis x acutiflora 'Karl Foerster'. This perennial will be appreciated in fresh rockeries, containers, borders, waterfalls, streams, banks, flower beds, or lagoons.

Planting and care
Plant Libertia in any ordinary, moist but well-drained, rather fertile and humus-rich soil. It requires a sunny position to flower. This perennial is hardy down to -7/-8°C (19.4/17.6°F) in well-drained and porous soil. In very cold climates, it may be useful to mulch the base of the plant in anticipation of heavy frosts. If seed formation is to be avoided, faded inflorescences should be removed.

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.
