They arrived as loose filaments scattered in the parcel... Fortunately, I managed to find them and plant them in pots, where they took well. We're starting to harvest now, which is lovely!

Description
Allium ampeloprasum produces small boles that are particularly tasty. This hardy perennial can remain in place for several years in the vegetable garden, making it ideal for permaculture. The leaves are consumed cooked, in the same way as other varieties of leeks. Plant from March to October for a harvest from September to May.
Allium ampeloprasum belongs to the large Amaryllidaceae family. It is the ancestor of the leek usually cultivated in vegetable gardens. It forms a compact clump, growing over time to a height of 60 to 80cm (24 to 32in). Its green leaves are sheathed, forming small shoots. It is hardy perennial (-25°C (-13°F)) that establishes itself in the vegetable garden for several years. It enters dormancy in summer and loses its foliage, which will reappear in autumn.
The small shoots have a tasty flavour that is appreciated in cooking. The leaves can be cooked and prepared like other varieties of leeks: in stir-fries, gratins, soups, stews, quiches, with cream or even in vinaigrette.
Harvesting: harvest as needed from September to May. Cut the leaves 2cm (1in) above the ground. Remove any soil that may have been pushed up for hilling, if necessary. The leaves regrow quite quickly, ensuring successive harvests on the same plant. In the first year, harvest moderately in spring to help the plant establish.
Storage: the leaves should be consumed quickly after harvest.
Gardener's Tip: plant it next to carrots. Do not grow it next to legumes (beans, peas, fava beans) in the same family.

Planting and care
Choose a sunny or partially shaded location. It prefers rich, well-drained soil with a sandy and limestone tendency. In acidic soil, a limestone amendment will be appreciated. A few months before planting, add well-rotted compost by raking it into the soil after loosening it. Remove any stones and weeds. Planting can take place from spring to autumn.
Space the bulbs 25cm (10in) apart in all directions. Dig a hole, place the root ball, and cover with fine soil. Firmly press down and water. Mound the plants, bringing the soil up a few centimetres in height.
Plan for an annual compost application on the surface.
It does not require watering in summer, even in hot regions. It is more resistant to diseases and pests, especially the leek moth.
It can multiply from the bulblets that form next to the main bulb.

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.
