Description
Lysimachia ephemerum, also known as willow-leaved loosestrife, is a tall and elegant perennial, and undoubtedly one of the most ornamental in the genus. It is clothed in silver and composed of stems covered with lanceolate leaves similar to willows. Its large floral spikes appear in summer, densely filled with small star-shaped white flowers with mauve veins. This robust plant thrives on the edge of water, especially on limestone soil. Its flowers can be cut to create beautiful bouquets.
Native to southwestern Europe, mainly Spain, Portugal, and France, this loosestrife prefers the vicinity of springs and colonises the limestone rocks and seeping areas of the Corbières, Dordogne, and the eastern and central Pyrenees. It belongs to the primrose family. From a thick and fibrous crown, it forms a bunch of sturdy, hollow, silver stems covered with narrow, elongated, beautiful almond-green leaves with silver highlights. The floral spikes reach a height of 1m (3ft) in July-August, at the top of the stems. They sometimes measure 30cm (12in) long and are composed of numerous small, white, star-shaped flowers, occasionally slightly tinged with violet, with mauve veins, and a diameter of 1cm (0in).
Willow-leaved loosestrife can be grown in flower beds and containers. It is perfect on the edge of water features or in damp rockeries, alongside cowslips, willowherbs, and vernonias. This plant is useful for its discreet yet effective presence in flower beds, where its upright habit and glaucous foliage highlight heavier plants or more vibrant blooms. It can sometimes become invasive if the conditions are suitable, self-seeding spontaneously in fertile, well-drained, and moist soil.

Planting and care
Sowing:
Sow from February to July on the surface of a good compost. Make sure the compost is moist but not waterlogged and enclose the tray or pot in a polythene bag until germination, which usually takes 30 to 90 days at 13-18°C.
If germination hasn't occurred after 30 days, place the pot or tray in the refrigerator, still in its polythene bag, and leave it at 3-5°C for 2-3 weeks, then bring it back to room temperature (13-18°C). Regularly monitor the progress while in the refrigerator and remove it immediately if you notice any signs of germination.
Transplant the young plants when they are large enough to handle into 8 cm (3in) diameter pots. Then place them outdoors, spacing them 30cm (12in) apart. Choose a sunny or partially shaded location and a fairly rich, loose, moist to wet soil with a tendency towards limestone.

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.
