Every knowledge on vegetables, health and nutrition.
Scientific Name
Valerianella locusta (Valerianaceae family)Common name
lamb’s lettuce, corn salad, field salad.
Varieties
Lamb’s lettuce has a rosette shape with rounded leaves, matte green in colour, with a velvety texture. Lamb’s lettuce grown in France is Valerianella locusta var. olitoria, from the Valerianaceae family. There are two main varieties of this lamb’s lettuce:
-Curly lamb’s lettuce with attractive round green leaves
-”Blond” lamb’s lettuce, with its longer, roughly spoon-shaped, light green leaves.
Vegetable garden: growing lamb’s lettuce
For ideal growing conditions, lamb’s lettuce needs sand !
Sown in open ground and exposed to the air, with a high tolerance of fresh winter temperatures, lamb’s lettuce is covered with a layer of sand that enables the young clusters to grow without harming the leaves.
Within 4 to 12 weeks, lamb’s lettuce grows to its full form. It needs a temperate climate, a light, deep and loose soil that runs through the fingers. Stores offer fresh lamb’s lettuce primarily in autumn and winter.
Consumption
The Pays de Loire region produces 90% of France’s lamb’s lettuce. Each French person consumes an average of 150 gr of lamb’s lettuce and 100 gr of watercress. However, these figures do not take into account plants grown in gardens.
Lamb’s lettuce is more popular with older, middle to upper class consumers in households of two to three people. The three regions of France in which lamb’s lettuce is most popular are: the Centre Est, Est and the Paris region.

Nutritionist’s advice
With its very high water content, lamb’s lettuce, like all salads and leafy vegetables, enjoys an exceptionally high nutritional density.
It is very rich in provitamin A (100 g is almost enough to satisfy your recommended daily intake!), rich in vitamin B9 and C.
In addition, lamb’s lettuce contains fairly significant levels of calcium and phosphorus.

Cooking and nutrition: tasty combinations
-The renowned beetroot, lamb’s lettuce and boiled egg salad is a classic on chef training courses. This tasty trio mixes the fresh, mild flavour of lamb’s lettuce with the mellowness of beetroot and the fullness of boiled egg, contrasted with the tangy note of the vinaigrette, to ensure a tasty meal all round. It also enjoys an array of nutrients: vitamins, fibre, protein, minerals.
-Lamb’s lettuce puree: a handful of lamb’s lettuce, thickened with a few mashed potatoes, and a dash of crème fraîche for a deliciously velvety puree filled with subtle flavours. Accompany it with crusty farmhouse croutons for a hearty and vitamin-filled meal.
Random tip
Broad beans are just as delicious either raw or cooked. Perfect for livening up a salad or mixture of vegetables as they are nicer with other ingredients rather than on their own.
Tip
Lamb’s lettuce or corn salad combines well with walnut or hazelnut oil, which brings out its mild and sophisticated flavour. Don’t leave lamb’s lettuce soaking in water for too long: it is better to rinse it under cold running water to maintain its vitamin content.
Additional info
150 g of lamb’s lettuce provides all your daily requirements of vitamins A and B9, almost all your vitamin C needs and a good proportion of your calcium and phosphorus requirements for just 30 calories! A record for a little salad! It’s hard to avoid talk of Omega 3s. These particular fats are currently being widely praised for the health benefits they offer and play a part in combating cardiovascular problems. Omega 3s are also thought to have a role in combating Alzheimer’s disease and contributing to emotional equilibrium. But they are not only found in oily fish and enriched margarines! Lamb’s lettuce is a very good source: over half the fats in lamb’s lettuce are Omega 3s, with 240 mg per 100 g. Purslane and no doubt many other wild salad leaves are also thought to be high in Omega 3s.
