Cool season, hardy annual. (Will stay green through much of the winter in USDA zone 6 and warmer.) Often called French parsley or gourmet’s parsley, chervil is an essential herb of French cooking along with chives, tarragon and parsley. Many cooks also like to add chervil to a bouquet garni. Though the light green, finely divided leaves resemble parsley, they have a distinct yet delicate licorice or anise flavor. The fresh leaves are perfect mixed with salads, sprinkled on fish or meat, added to egg dishes and even cold drinks such as tomato juice.
