Description

The large Elbeuf Monstrous leek is originally from Normandy. Its stem is short but thick. The light green leafy part is predominant on this sturdy leek but remains tender. It is worth noting that vitamins are more abundant in the green parts of the plant.
Elbeuf Monstrous has a pronounced flavour. Reserve it for dishes where it will be highlighted.
It is sown from January to May and harvested from June to December.

The leek or Allium porrum is a biennial herbaceous plant belonging to the Alliaceae family. Originally from Central Asia, it was known to the Egyptians as early as 1500 years BC. Its foliage was long and very thin at that time. The Romans also liked it. Its appearance was then similar to that of its cousin the onion, with a very slim stem and a well-rounded bulb. It had already been introduced throughout Europe by the Middle Ages.

The leek has long blue-green or dark green leaves that are wide and sheathing, forming the stem, which resembles a stalk. This stem is the most prized part. It is white and its taste is very delicate in the underground part that has not been in the light. At the end of the second year, it produces a stem topped with a spherical purple umbel the size of a tennis ball, which has become the emblem of Wales.

This very hardy vegetable, some winter varieties can withstand temperatures below -15 or even -20°C (-4°F), can be sown for a large part of the year (February to August). Considered a winter vegetable, it can be harvested almost all year round. Leek is rich in dietary fibre, aiding digestion. It is also rich in vitamins C and B, as well as sulfur compounds with antioxidant properties. It is reputed to lower cholesterol levels in the blood the same as onions, among other benefits.

It is good for health but also tasty: its flavour is halfway between onion and asparagus, which has led to one of its nicknames "the poor man's asparagus". The white stem and the rootlets are mainly consumed. It is used in many local dishes around the world. It can be consumed in soups, quiches, cold in vinaigrettes, or even thinly sliced raw in salads, etc. The Japanese particularly like it: it can be found in many recipes such as sushi and sashimi or delicious sesame leeks.

Harvesting: Pick your leeks as you need them. They are usually ready to harvest between 5 and 8 months after sowing. Gently pull on the leek to avoid damaging the stem. You can use a small spade a few cm away from the desired leek and lever it out more easily.

Storage: You can keep them for two weeks in the vegetable drawer of your refrigerator. They can be kept for almost 3 months in the freezer. Bag them after blanching them for a few minutes, rinsing them under cold water, and then drying them carefully.

The gardener's tip: Grow leeks with carrots. The carrot fly dislikes leeks, and the leek fly does not care for carrots! Tomatoes, lettuces, and strawberries are also good companion plants for leeks, but leeks don't like to be near their cousin, the onion, or beets and beans.

To determine if a leek needs to be watered, simply observe its foliage: if it stands tall, everything is fine, it is not thirsty. If its foliage wilts and leans to the side, it probably needs a drink of water.

Planting and care

Leeks are considered winter vegetables. This is partly true, however there are a number of leeks for the summer. The leek's growth cycle is quite long and occurs in several phases.

Soil preparation: Leeks like rich and deep soils enriched with organic matter. However, the soil must have been enriched several months in advance. Leeks prefer a widely sunny location in generally moist, well-prepared soil.

Sowing: Dig a furrow 2 cm (1in) deep and sow a few seeds every cm. Cover the seed and lightly firm with a rake. Sow from February to May under cover, depending on the climate (greenhouse, tunnel, etc.). Germination will take between fifteen days and three weeks. Once the plant has reached about fifteen cm in height and the thickness of a pencil, it is now time to transplant. Before doing so, you can delicately uproot the young plants and let them dry out on the ground, in the shade for two days. This will remove the leek's smell and hopefully avoid attacks from onion fly.

Transplanting: Prepare the leek. "Preparing" means cutting the roots 2 to 3 cm (1in) below the bulb and at the same time cutting the young leaves a few cm above the stem. The objective is twofold: removing the roots allows for better rooting by stimulating new roots and cutting the leaves reduces evaporation.
Then, prepare holes about fifteen cm deep spaced 15 to 20 cm (6 to 8in) apart in all directions. Insert your young plants into them. The white part must be completely covered. Water generously at the base of the leeks, which will close the holes around the stem. They need a nitrogen-rich soil. You can place freshly mown grass between the rows. After a period ranging from fifteen days to a month, the plants grow and strengthen. Then you can mound up the soil around the stem to keep it protected from light so that it remains white and tender.

Storing: There are summer varieties and winter varieties depending on their hardiness and the period when leeks should be sown. Autumn sowings can be harvested in spring. This means that some of them will spend the winter outside. In regions with harsh winters, it is sometimes necessary to store the leeks, that is, to gather them in a place protected from the wind and to plant them temporarily before transplanting them again in spring.
