Growing Chervil: A Complete Profile
By Growing Home Greens Team · August 10, 2026
Chervil is one of the classic French fines herbes, a delicate, anise-and-parsley-flavored annual that fades fast once cut or cooked, which is why it’s almost always added at the very end of a dish rather than during cooking.
Sowing it for cool weather
Direct-sow in early spring, or about 60 days before your first fall frost for an autumn crop, since chervil is a cool-season herb that bolts quickly once summer heat arrives. It can also be started indoors about 8 weeks before your last frost. Seed needs light to germinate, so barely cover it rather than burying it; germination takes 10 to 14 days. Space plants 6 inches apart in rows at least 12 inches apart.
Harvest before it flowers
Cut leaves just before the plant starts to flower, when the anise flavor is at its peak. Once chervil bolts, the leaves turn bitter fast, so in a hot spring, plan to harvest earlier and more aggressively than you would with a slower-bolting herb like parsley.
Delicate flavor, delicate handling
Chervil’s flavor fades quickly with heat and time, which is why it’s traditionally added at the end of cooking rather than during it, and used fresh rather than dried whenever possible. It pairs classically with fish, eggs, and other mild dishes where a stronger herb would overwhelm it.
Chervil has no recorded companions or antagonists in our data. See the full companion guide for chervil for how it’s tracked. At 4 plants per square foot, it fits the Garden Designer’s grid the same way parsley does, best planted as a spring or fall crop rather than fought through summer heat.

Varieties worth considering
- 'Vertissimo' chervil (best for: cold tolerance, winter sowing): Johnny's Selected Seeds describes this as a Brussels Winter type with dark green leaves, bred for better cold tolerance than the standard curled type. (source)
- 'Fine Curled' chervil (best for: standard curled type): Johnny's Selected Seeds' organic offering, similar to Vertissimo but the standard curled-leaf type most seed packets sell, with the lacy, fern-like leaves chervil is known for. (source)
