Chervil, a delicious herb

Chervil in a patch

A subtle but strong flavour, best enjoyed fresh since it fades on drying, makes chervil (Anthriscus cerefolium) a favourite in omelettes, fried mushrooms, mixed salads and soups. It grows fast and easily, yet dislikes heat: give it light, cool, well-drained soil and shade through summer, and leaves are ready within weeks.

Sowing and planting chervil

Planting chervil, or sowing for those who prefer to start from seed, is rather easy.

First of all, chervil is an herb that doesn’t cope well with heat. It’ll be fine in the sun in spring and fall but will need shade in summer.

Soil and location for planting chervil

Chervil likes well-drained, light and rather cool ground.

  • For chervil purchased in pots, you can plant from spring to summer.
  • Select a partially shaded emplacement, especially in summer.
  • Indoors, avoid windowsills that are often too hot for chervil.
  • Water when the soil is dry but without overdoing it, or the roots will drown.

Sowing chervil

Planting and care for chervil
Chervil is best sown in spring or autumn

Chervil is preferably sown in spring or fall.

  • You can sow chervil directly in the ground from mid-spring to early autumn.
  • To sow as early as late winter, you’ll have to find a place that is protected from from freezing.
  • As soon as the first leaves appear, thin down to about 4 inches (10 cm) to give the sprouts enough space to develop.
  • Sprinkle water over lightly to keep the substrate a bit moist.
  • Transplant to the ground, pot or garden box when there isn’t any risk of freezing any more.

Diseases and parasites that attack chervil

Even though it isn’t very vulnerable to diseases and parasites, like most herbs and spices, chervil is nonetheless subject to being invaded by aphids and fungus, downy mildew and rust.

Chervil troubles and how to tell them apart

Chervil is rarely troubled, but three problems account for almost everything you will see on the leaves. The symptom tells you which one you are dealing with.

Chervil troubles and how to tell them apart
Problem Type Symptom on the plant What to do
Aphids Pest Small insects clustered on the stems and leaves Treat against aphids
Downy mildew Fungus A type of mould on the leaves, which end up turning yellow Apply organic treatments to eradicate it
Rust Fungus, least common case Leaves marked with brownish orange spots Follow the treatments used to fight rust

Like most herbs and spices, chervil isn’t very vulnerable, so a glance at the leaves each time you harvest is usually enough.

Harvesting chervil

Harvest comes quickly after the sowing because there’s about 1 to 1½ months lead time from sprouting to harvest for the first chervil leaves.

Leaves are cut off whenever they’re needed, during the entire vegetation phase. Best wait for a full month after sowing though.

  • Snip the leaves at the base of the stem because new shoots will appear.
  • Collecting them in the morning makes for a better result as regards flavor retention.
  • With cut-and-come-again leafy crops such as chard, kale, loose-leaf lettuce and spinach, harvest the outer leaves first and leave the young central shoots intact, so the plant keeps producing new growth.
  • Pinch out flower stems as soon as they appear, because once chervil runs to flower the leaves turn coarse and lose their fragrance.
  • Let one or two plants flower and set seed, and chervil will often sow itself for a following crop.

Common chervil or ‘Crispum’ chervil, this herb presents us with a subtle strong flavor that you will prefer fresh because it tends to lose its taste when dried.

Chervil with other herbs
Snipped fresh into omelettes, salads and soups

It is native to Asia and it part of the wide Apiaceae family. Although it is part of the same family as turnip-rooted chervil, they clearly are of different species. As if to prove the point, turnip-rooted chervil leaves aren’t edible.

Being rather easy to grow, this plant is delicious when added to omelets, fried mushrooms, mixed salads, soups and gravy meals.

If you wish it to keep, it is best to freeze it, putting it in an airtight jar before doing so.

Chervil self-sowing flowers

It’s also possible to simply hang it upside-down in a dry spot of the house, and you can snip off leaves as you need them.
