Description
The Chervis is a perennial herbaceous vegetable plant that grows up to 150 cm (59in) tall. It is cultivated for its swollen and fleshy tuberous roots, which have a whitish-grey colour and a taste similar to parsnips. The young shoots are edible and can be used in mixed salads. Sowing period is from September to November for a harvest 6 months later.
Chervis is native to Eastern Europe, Central Asia, and Western Asia. This vegetable was introduced to France around the 15th century from Germany and Russia. It was served at the tables of kings. The cooked roots can be consumed in the same way as salsify: in salads, with butter, fried with sugar and orange juice, and accompanied by a Béarnaise sauce. Chervis has no known properties.
Chervis requires a deep and moist soil with an annual compost application (3kg/m²) at the end of winter.
Harvest: The roots are harvested as needed from mid-October to the end of March.
Storage: Once harvested, the roots can be stored for a few days in a cool place.
Gardener's tip: To facilitate harvesting during freezing temperatures, cover the ground with dry leaves or straw.

Planting and care
Sowing
From September to November, trace furrows 2 cm (1in) deep spaced 40 to 50 cm (16 to 20in) apart. Then, place the seeds at the bottom of the furrow, cover with fine soil, firm down with the back of the rake and then water.
Germination occurs in 12 to 15 days. One month after sowing, when the young plants have 4 to 5 leaves, thin out the plants, keeping only one every 25 cm (10in).
You can sow in a nursery and transplant the young plants when they have 5 to 6 leaves.
Maintenance
Chervil is sensitive to drought. From May, spread a thick organic mulch (dead leaves, previously dried grass clippings) to keep the soil moist. Water abundantly at the base throughout the summer. Beware of slugs and snails!

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).
