Key Facts
- A cool season herb in the carrot family Apiaceae
- Delicate fernlike leaves with a mild anise or anise-parsley flavor
- Commonly used fresh in salads, soups and as a garnish
- Usually grown as an annual or short-lived perennial in mild climates
- Produces small white umbel flowers in spring
- Prefers cool, moist, well drained soil and some protection from hot sun
- Easy to grow from seed and may self seed in favorable conditions
Chervil is a cool season herb in the carrot family grown for delicate fernlike leaves and a mild anise parsley flavor. It is prized fresh in salads soups and as a garnish but performs poorly in hot sun so choose a cool sheltered spot.
Identification
Chervil has fine feathery leaves that form a small clump about 30 to 60 cm tall and 15 to 30 cm wide in cultivation. Small white umbels appear in spring. The overall habit is compact and delicate which makes it easy to spot among coarser leafed herbs.
Best uses and where to grow
Use chervil as a finishing herb for salads soups and egg dishes where its mild anise notes shine. It suits cool partial shade beds herb edging and containers where soil stays evenly moist. Avoid planting in hot exposed locations because strong sun reduces leaf tenderness and flavor.
Planting and timing
Sow seed in cool weather either in early spring or in autumn where winters are mild. Direct sowing into the final bed is the common method though starting seed indoors gives an earlier crop. Plants tolerate light frost but will not survive prolonged hard freezes so time sowings for cool growth periods.
Soil light and watering
Give chervil fertile well drained soil that stays consistently moist. Provide partial shade in warm climates and some afternoon protection in hotter sites. Water regularly to keep soil evenly damp since dry hot conditions cause leaf quality to decline and may trigger premature flowering.
Spacing and containers
Plant chervil about 15 to 30 cm apart to allow a small clump to form and good air movement around foliage. It grows well in containers and makes a neat edging plant. In pots use a humus rich potting mix and check moisture more often as containers dry faster than garden beds.
After flowering and controlling spread
Flowering reduces leaf production so remove flower heads if you want to prolong leaf harvest. Chervil can self seed freely in favorable conditions so pull or trim seed heads to limit spread. Allowing some seed to drop will naturalize chervil in a garden patch if that outcome is desired.
Propagation and general care
Propagate primarily by seed sowing directly where plants will grow or start indoors for an earlier crop. Feed lightly with a balanced fertilizer if growth is slow and harvest leaves regularly to encourage fresh foliage. Replace plants after a season or two in warm areas since they are usually treated as annuals.
Frequently asked questions
- How fast does Chervil grow?
- Chervil establishes quickly in cool moist conditions and produces usable leaves within weeks. It typically reaches its mature height during the season rather than over multiple years.
- Is chervil a perennial?
- Chervil is usually grown as an annual or a short lived perennial in very mild winters. In most climates treat it as a cool season annual.
- Is chervil safe for pets?
- Chervil is an edible culinary herb and is not commonly listed as toxic to pets in major horticultural references. Check ASPCA or local poison control for definitive pet safety information.
- Can I grow chervil in pots?
- Yes chervil does well in containers where soil remains cool and moist. Use a humus rich mix place the pot in partial shade and water more frequently than garden beds.
- When should I harvest chervil?
- Harvest leaves while foliage is tender for best flavor especially before plants flower. Pick outer leaves regularly to encourage new growth and avoid letting plants go to seed if you want continued leaf production.
