Although this herb is a hard herb to grow in the south, for the heat, and humitity, which it does not  like, I have grown it and used it. Tarragon has a sweet peppery flavor.  It enhances flavors of fish, pork, beef, lamb, poultry, potatoes, tomatoes, carrots, onions, musrooms, cauliflower, broccoli, beets, peas, parsley, lemons, oranges, rice, and barley.  Use in sauces, omelets, and in vinegar. For maximum flavor add to dishes during the last 15 minutes. Has been used to stimulate the appetite, relieve colic, and to relieve a toothache.  It may be used as an antifungal as well. Its a great herb. The Herb Lady
