More information

Celtuce, also known as Asparagus Lettuce or Chinese Stem Lettuce, is a very original lettuce variety. It bears green, narrow leaves that do not form a heart. It quickly goes to seed, offering a large central stem which, once peeled and cooked, can be eaten like asparagus. Its flavour is sweet and refined and goes well with nutmeg. Although its leaves don't have a very distinct flavour, they can also be eaten cooked. Sow from March to June and harvest from May to August.

Description

Celtuce, also known as Asparagus Lettuce or Chinese Stem Lettuce, is a very original lettuce variety. It bears green, narrow leaves that do not form a heart. It quickly goes to seed, offering a large central stem which, once peeled and cooked, can be eaten like asparagus. Its flavour is sweet and refined and goes well with nutmeg. Although its leaves don't have a very distinct flavour, they can also be eaten cooked. Sow from March to June and harvest from May to August.

Lettuce is one of the most popular vegetables thanks to its deliciously fresh texture and flavour and its numerous health benefits. Generally eaten raw in salads, it is also very good cooked (with peas, for example!)

Lettuce is an annual plant that belongs to the great Asteraceae family. Its Latin name is Lactuca sativa: “lactuca” refers to the white sap that appears when the leaves and stems are cut, "sativa" means "cultivated".

Lettuce an essential member of any self-respecting vegetable garden. With so many varieties available, it can be grown almost all year round. So long as you comply with the growing calendar of the chosen variety, it is easy and quick to grow and will do well in most rich, moist soils.

Harvesting: cut the stems off at their base when ready.

Preservation: Lettuce can be stored for a few days in the refrigerator but is best eaten fresh.

Useful tip: During hot summers, lettuce exposed to direct sunlight tends to wilt and look miserable. To avoid this, protect the plants from intense sunlight by covering them with overturned crates. Summer lettuces don’t have to be grown in rows: dot them around your vegetable garden, under runner beans, in the middle of a cucumber or squash patch. They will benefit from the extra shade.

NB. Organic seeds (in French "AB" for "Agriculture Biologique") are produced from plants that aren't treated with phytosanitary products (insecticides, weed killers). The seeds do not undergo post-harvest treatment. They carry the AB label and are approved by Ecocert, an independent structure.

Planting and care

Sowing:

Lettuce germinates at a temperature of about 18°C and usually takes around 10 days.

Sow under cover (cold frame) from February to April or directly outdoors from March to July.

In loose, well prepared soil, sow the seeds in rows, 4 cm apart, 0.5 cm deep and cover with soil. Leave about 15 cm between each row. When the seedlings are strong enough, thin them out by keeping one strong plant every 15 cm.

If slugs and snails are a problem in your vegetable garden, sowing under cover in small pots may be the best option. The plants can be moved to their final position when they are big enough.

 

Where to grow:

Lettuce is not a very greedy vegetable, but it does require humus-rich soil or else it tends to bolt (go to seed) fairly quickly. Prevent this by raking a bit of well-rotted compost into the top 5 cm of the prepared seed bed in the autumn. Lettuce does well in slightly acidic to neutral soils (PH between 5.5 and 7.5) that are kept moist. Remember to water regularly.

Lettuce can be easily grown alongside other slow-growing vegetables such as beans, tomatoes, cucumbers etc. Avoid growing lettuce next to maize plants.
