Cultivation Details

Plants are hardy to about -10°c[].
Prefers a well-drained moisture retentive soil[]. Plants dislike hot dry summers[], it is best to give summer crops a cool shady position but winter crops require a sunny position[, , , ]. Tolerates a pH in the range 5.8 to 7.6.
Chervil is occasionally cultivated as a salad plant, especially in France[]. There are some named varieties[]. It can supply fresh leaves all year round from successional sowings, especially if given some protection in winter[].
The leaves are ready for harvesting in about 8 weeks from sowing, the plant responds well to cut and come again harvesting[].
Although a biennial, the plant is usually cultivated as an annual[]. It often self-sows when grown in a suitable position[, ].
Be careful if harvesting this plant from the wild because it is superficially similar to some poisonous species such as young plants of hemlock, Conium maculatum[].

Edible Uses

A mild aromatic flavour[] that is suggestive of aniseed according to some[], whilst others suggest a light, parsley-like flavour with a hint of myrrh[]. The leaves are often used as a flavouring, they form the basis of the seasoning 'fines herbes'[] and are an essential ingredient of 'bouquet garni'[].

Agroforestry Uses:

Chervil is an aromatic plant with pleasantly scented leaves[]. It is said to be a good companion plant for growing with carrots and radishes[, ], the radishes becoming hotter and crisper[]. It also grows well with dill and coriander[]. When grown with lettuces it is said to protect them from aphids and ants, the plant is also said to repel slugs[].

Other Uses

The growing plant is said to repel slugs[].

The dried plant is used in pot-pourri[].

The plant contains an essential oil that is used as a flavouring and in cosmetics etc[]. The essential oil is characterized by 3 main constituents: undecane, methyl chavicol (estragole) and methyl eugenol. These compounds constitute about 95% of the oil. The composition of the essential oil varies at different stages of growth - undecane increases to a maximum of about 20% after flowering,; methyl chavicol increases to a maximum of about 70% at full flower; and methyl eugenol reaches a maximum of about 70% before flowering[].

Propagation

Seed - sow in situ in succession from late winter to early autumn. The seed usually germinates in 2 - 3 weeks[]. The late winter, late summer and early autumn sowings should be made in a very sheltered warm and sunny position outdoors or under some protection such as a frame. Other sowings can be made in a position that has at least some shade from the midday sun since the plant runs to seed quickly if it gets too hot or the soil is dry[]. The seed only remains viable for about a year[].
