Description
Lettuce 'Grosse Graine' is an early variety that produces long, tasty, slightly flattened green leaves. It is a generous lettuce, ideal for autumn salads. It is sown in August and September for harvest from September to November.
Lettuce, or "Lamb's Lettuce," is a small salad with rounded leaves arranged in rosettes. It is THE little salad of autumn and winter, although some varieties known as "all-season" can be sown and harvested throughout the year. Varieties with large seeds have larger leaves but are less cold-resistant than those with small seeds.
Lettuce belongs to the Caprifoliaceae family (like Honeysuckle) and grows wild throughout Europe to the point where it is sometimes considered a "weed."
This little salad is mainly consumed raw, on its own or accompanied, for example, by kiwi and avocado or beetroot, but can also be cooked, like spinach. It has remarkable nutritional value, being low in calories but particularly rich in vitamin C (three times more than Lettuce), vitamin E, and beta-carotene.
Cultivating Lettuce is easy, but the sowing must be done in firm soil, and it is important to ensure the soil remains moist.
Harvest: With a knife, lettuce is harvested as needed by cutting the rosette just above the collar.
Storage: It can be stored for a few days in the refrigerator's vegetable drawer.
Gardener's Tip: If you are gardeners who tolerate a bit of disorder, even in the vegetable garden, don't hesitate to let some rosettes go to seed in the spring. They will self-seed and provide you with some greenery on your plate at no cost or effort!

Planting and care
Sowing: The germination of Lamb's Lettuce occurs at about 14°C. The seedlings emerge in approximately 10 days.
Sowing is done in September/October for a harvest from December to March.
On firm soil, not dug up, just raked, make furrows spaced 15 to 20 cm (6 to 8in) apart, with a depth of one centimetre. Sow in rows, spacing the seeds 0.5 to 1 cm (0in) apart, cover with a bit of fine soil and firm down the sowing with the back of a rake. Keep the soil moist until the seedlings emerge. Lamb's Lettuce is preferably sown in shade or partial shade. If this is not possible, cover your sowing with a light mulch, like a very thin layer of herb, to maintain good moisture until the arrival of autumn rains.
Sowing can also be done by broadcasting, using 5 to 7 grams (12 grams for varieties with large seeds) for 10 m2.
Cultivation: Lamb's Lettuce is not demanding and does not require any prior fertilisation. Varieties intended for winter cultivation are hardy, but up to a certain point... Remember to protect them from extreme cold during harsh winters by covering them with a winter veil or a layer of straw.
It is a salad that grows very well in a cold greenhouse or under a polytunnel.
As for companion planting, Lamb's Lettuce is a good neighbour. You can sow it at the base of many vegetables and interplant it between rows of Escarole, Spinach, Radishes...

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.
